Key updates across Nebula and Specter.

38 updates

Feature

Redesigned Portal, Google Sign-in & Team Roles

The portal is reorganized into fewer, clearer pages, with Google sign-in, one-link onboarding and team roles.

  • Sign in with Google. Verification and invitation emails sign you straight in — one link, no second login.
  • Files chosen before signing up are kept while you confirm your email address.
  • Navigation is grouped into Work, Admin and Developers, the credit balance stays in view, and menus and tables fit a phone screen.
  • Billing is one page — overview, usage by month, history and plans — and an upload checks the balance and spend cap before it starts.
  • Team: change member roles and transfer ownership from one place.
  • Re-run a document or a whole batch with different settings, and unlock every password-protected file in a batch with one password.
  • Messages, errors and dates follow the language you choose, and the API keys page carries a quickstart and a Japanese developer guide.
Improvement

Batches, Spending & Account Security

Batches say exactly what finished, spending is easier to follow, and the AI apps connected to your account can be reviewed and revoked.

  • A batch can cancel the files still waiting, and its ZIP download names any file that has no result.
  • A batch is checked against the balance as a whole before it starts, and files that will reuse an earlier result are not counted.
  • Cancelling a conversion returns the credits held for it.
  • Usage history labels every entry, counts the month in Japan time, and a spend alert can be cleared.
  • Settings lists the AI apps connected to your account, and any of them can be revoked.
  • Changing or resetting your password revokes your personal API keys and every connected app.
  • Free conversions without an account are protected by a bot check, and cookie settings live in Settings — analytics load only after you consent.
v1.14.1Improvement

Account and Sharing Security

Password changes end other sessions, two-step setup asks for your password, and people join an organization only by accepting an invitation.

  • Changing your password signs out every other session; resetting it signs out every session and forgets trusted devices.
  • Setting up two-step verification asks for your current password.
  • People join an organization only by accepting an invitation.
  • A share link shows only the file it was created for.
  • Specter can no longer be embedded in another site’s page.
Announcement

One Price: ¥1 per Page

Every page costs ¥1 on every model, with monthly plans and one-time purchases priced in yen.

  • ¥1 per converted page on every model — 1 credit = ¥1 = 1 page — charged only for successful jobs.
  • Monthly plans: Basic, ¥1,500 for 1,500 pages, and Power, ¥4,500 for 4,500 pages. Unused plan pages expire when the plan renews.
  • Buy any amount from ¥1,000 to ¥10,000 without a plan, in place of fixed credit packs. Bulk volumes are invoiced.
  • Prices exclude consumption tax.
  • Free credits granted at signup are valid for 30 days.
  • A conversion that reuses an earlier identical result costs 0 credits.
Feature

Nebula in Your AI Assistant (MCP)

Claude, ChatGPT and other MCP-compatible assistants can convert documents through Nebula, signed in to your own account.

  • Add Nebula to Claude, ChatGPT, Claude Code, Codex or another MCP-compatible assistant, then ask for a document to be converted in plain words.
  • Open to every Nebula account as a Beta.
  • Sign in with your Nebula account through OAuth, or use an API key.
  • A file attached in chat reaches Nebula through a one-time upload link, not as text pasted into the conversation.
  • Photos are read by the assistant itself; documents go to Nebula.
  • Setup steps for each assistant are in the API docs, under “AI assistants (MCP)”.
  • API: job submission accepts an Idempotency-Key, and an unsupported file is refused at upload with the list of accepted types.
v1.14.0Feature

Source Statements, Spreadsheet Sources & DD-Format Export

Financial baselines are built from the statements as the source documents print them, Excel files included, and export in a due-diligence report layout.

  • Source statements (決算書) view: statements and 内訳書 schedules exactly as printed, each figure traceable to its file, page and printed label.
  • An item reported in several documents is shown as one line, with each document it came from.
  • Excel sources: sheets are mapped to statements, periods are read by column, and rows hidden in the workbook are marked.
  • Valuation: the DCF says when a value is not meaningful instead of printing a figure, flags an enterprise value far from the market range, and shows the basis for each forecast driver.
  • DD-format workbook: a 正常収益力 sheet with normalized EBITDA by period, adjusted net assets (実態B/S) on one sheet, and a net-cash sheet with tax-effected bridge items.
  • The equity bridge proposes items such as 倒産防止共済 and 資産除去債務 for the analyst to accept.
  • Pages scanned sideways or upside down are turned upright before they are read.
Improvement

Cross-Page Tables, Two-Page Spreads & Tables to Excel

A table split across pages comes back as one table, and every table in a result can be downloaded as an Excel workbook.

  • A table that continues onto the next page is merged back into one table. Where the boundary is unclear, the model decides from both pages.
  • Period columns in born-digital financial statements are read from the PDF’s own text layer, so the figures are not retyped.
  • Scanned two-page spreads are read as two pages, in reading order.
  • Download a result’s tables as one .xlsx: a Contents sheet, then one sheet per table with its title and the text around it.
  • Pages are split into evenly sized batches, so a long document no longer waits on a small final batch.
Improvement

Every Excel Format Read from Its Cells & Office Previews

Older Excel formats are read from their cells instead of as page images, and Word and PowerPoint files are shown beside their result.

  • .xls, .xlt and .xlsb workbooks are read from their cells, keeping the grid, instead of being converted to page images and read as images.
  • Plain-text and Markdown files pass straight through without conversion.
  • Word, PowerPoint, OpenDocument and RTF uploads show the source document side by side with the result.
  • An office-document conversion that stalls is stopped at a time limit, so it no longer leaves a job stuck.
v1.13.0Feature

Answer-First Valuation, Transaction Perimeter & Version History

Valuation opens on the answer and runs on its own, the deal perimeter can be defined, and any earlier baseline can be restored.

  • The Multiple and DCF tabs open on the answer — enterprise value range, equity value and value per share — with the working one click away.
  • Valuation runs automatically once the baseline is generated, and estimates and evidence gaps are flagged beside the number instead of hiding it.
  • One status vocabulary across valuation — Specter estimate, Analyst input, Market source, Evidence gap — and WACC and terminal assumptions are edited in place.
  • The valuation workbook opens on a summary sheet, with the DCF forecast laid out by year and the equity bridge beneath it.
  • Transaction perimeter: define the business being acquired, the operations included and excluded, and how shared items are allocated. Changing it clears statements built on the old perimeter.
  • Version history: open any earlier baseline in full and restore it as the current one. A valuation can be regenerated in a chosen language, and a generation in progress can be cancelled.
  • Projects show whether they are yours, your organization’s or shared with you, with a filter to match; anyone a project was shared with can leave it, and the Data Room’s “Added by” column names who added each file.
Feature

Import Folders from Google Drive, OneDrive, Box & Dropbox

Link a cloud folder and Nebula converts its files as one batch.

  • Connect Google Drive, OneDrive, Box or Dropbox, pick a folder, and its files are converted as a batch.
  • “Import from cloud” sits beside Upload files and Upload folder.
  • Imported files are converted with the same settings as files uploaded by hand.
  • A file identical to one already converted is marked “Reused result” in the folder view and on the job page.
v1.12.0Feature

Organizations, Sharing & Baseline Review

Share projects across an organization, and accept baseline figures a reporting period at a time.

  • Organizations: access decisions now resolve in one place, and sharing a project works end to end.
  • Financial baseline: accept a whole reporting period at once instead of line by line.
  • The tracking list replaces the old export view, with per-row fulfillment status and pinned rows on by default.
Announcement

SOC 2 Type 2 and GDPR Compliance

Ur AI completed its SOC 2 Type 2 examination and GDPR compliance programme, covering the controls Specter runs on.

  • Audit logging, access control and admin accountability were built to the SOC 2 criteria rather than retrofitted to them.
  • GDPR data-subject rights are served by real endpoints — access, erasure, portability and records of processing.
  • The Trust Center at trust.ur-ai.net carries the current reports and control status.
Improvement

Encrypted Files, Orientation Correction & Template Formats

Password-protected uploads wait for a password instead of failing, and pages are turned the right way up before they are read.

  • A password-protected upload parks as “needs password” and waits at an unlock step, instead of failing as unreadable.
  • Pages are checked for orientation before conversion and corrected, with a backup model when the primary one fails.
  • Excel template formats (.xltx, .xltm) go through the synchronous fast lane.
  • Spreadsheets carrying images are routed to the full pipeline, so nothing embedded in them is lost.
  • The upload allow-list accepts every file type Specter handles.
v1.11.0Feature

Cloud Data Room Connectors & the Equity Bridge

Import straight from Google Drive, Dropbox, Box or OneDrive, and bridge enterprise value to equity value with diagnostics you can audit.

  • Connect Google Drive, Dropbox, Box or OneDrive to a project and import into the Data Room with the cloud folder structure preserved.
  • Sync is on demand, not continuous: a freshness badge shows when a linked folder has changed, and you press Resync. A re-import skips any file whose content hash proves nothing changed, and every file that fails records why.
  • Unlink a cloud folder whenever you like — the files already imported stay where they are.
  • Equity bridge: a balance-sheet bridge from enterprise value to equity value, with its own table, diagnostics and export.
  • Valuation now covers negative-EBITDA cases through an EV/Sales route, a net-asset-value floor, and an explicit build-options view.
  • Staleness banners say when a projection or valuation no longer reflects the figures underneath it.
v1.10.0Feature

Report Export & Grounded Research

Export a finished report as Markdown, Word or PDF, and see exactly which research run produced what you are reading.

  • Export a report as Markdown, Word or PDF, with an executive summary generated only from what the report itself contains.
  • Research carries provenance at the run level: a report says which research produced it, and a banner appears when research it expected is missing.
  • Red Flags can generate its own structure when a project has none, gated on what that project actually supports.
  • A notification says “ready with gaps” when a step did not run, instead of reporting plain success.
  • One confirm dialog across the application; the browser’s native dialogs are no longer used.
  • Uploads are checked against the allowed content types in the browser, and server-side rejections are surfaced rather than swallowed.
v1.9.0Feature

Valuation Baseline, Comparables & Analysis Language

Driver-level projections that fade to a terminal rate, comparables you can regenerate deliberately, and one resolved language per analysis.

  • Financial baseline: driver-level projections that fade to a terminal rate, approved EBITDA adjustments shown in both the waterfall and the table, and diagnostics that explain a valuation’s sign.
  • Comparables: complete target profiles with an explicit regenerate action, published under a fencing token so two regenerations cannot collide.
  • One analysis language is resolved at every baseline entry point, and the prose the interface writes is localized with it.
  • Email notifications for structure and classification milestones, grouped into a section digest rather than sent one at a time.
  • A step that legitimately finds nothing to do is treated as done, so the steps depending on it are no longer left blocked.
Feature

Organizations, Retention Controls & Zero-Data-Retention Keys

Bill a whole organization centrally, and decide per API key how long — if at all — Nebula keeps what you send it.

  • Organizations: an owner, members, and billing held centrally for the organization rather than per user.
  • Zero data retention can be opted into when an API key is created — content is swept rather than kept.
  • A retention purge engine, plus a 30-day erasure sweep after an organization is closed.
  • Terms of service consent is captured at signup, with a re-consent gate when the terms change.
  • A budget alert at 80% of your monthly cap, and an expiry date shown per credit purchase.
  • Close your own organization from the portal, without going through support.
  • Custom prompts and crop policy can be set per account for organization tenants.
Feature

Public API Docs, Self-Service Keys & Unified History

Read the API reference, mint your own key, and search your whole conversion history rather than the page in front of you.

  • Public API documentation — a guide plus an interactive reference you can call directly from the page.
  • Mint, list and revoke your own API keys from the customer portal.
  • One History view across single files and batches, with search that covers your full history rather than the current page.
  • Search inside a batch, seeded from whatever you searched for in History.
  • merged.md follows the order you requested the documents in, so the output is reproducible.
  • Unsupported file types are refused at the front door, with a reason you can act on.
Feature

Reasoning Effort, Layout-Aware Conversion & Faster Throughput

Trade speed against accuracy per job, and read each region of a page with an instruction chosen for that region.

  • Choose reasoning effort per job — maximum speed at one end, maximum accuracy at the other — and the choice persists for your session.
  • Layout-aware crop reading: the page is segmented, each region cropped, and each crop read with an instruction resolved for that region.
  • Handwritten regions are routed to the model that reads them best.
  • Images take a fast path straight to the vision model, skipping the render stage they do not need.
  • A distributed rate governor keeps concurrency dense without tripping provider limits, with per-model rates.
  • Model coverage extended across current-generation GPT and Claude models, each with effort variants.
Announcement

Nebula is publicly available

Nebula opened to anyone with an account: turn Japanese and English business documents into layout-preserved Markdown and structured JSON, in the browser or over the API.

  • Charts, tables, forms, presentations and scanned pages convert with their structure intact.
  • Japan-hosted, with per-tenant isolation. Documents are not used to train models.
  • Available in the browser at nebula.ur-ai.net and over an authenticated API.
v1.8.0Feature

Notifications, Encrypted Files & a Faster Data Room

Know the moment work finishes, open password-protected files without leaving the app, and wait less for large libraries.

  • A notification bell with live arrival toasts and deep links into the work that just finished.
  • Password-protected files are detected on upload and opened with a password prompt, instead of failing as unreadable.
  • Batch uploads are fault-isolated: one file’s failure no longer takes the batch with it, and interrupted uploads retry.
  • Ingestion carries a completeness invariant, so financial rows are never silently dropped.
  • PowerPoint and Markdown files preview inline, and legacy .doc uploads work end to end.
  • A broad performance pass across ingestion and retrieval — parallel table fetches, pooled CPU work, and PDFs rendered in page ranges from a single open.
Feature

Accounts, API Keys and Prepaid Credits

A customer portal with real accounts, keys you control, and prepaid credits that stop rather than surprise you.

  • A customer portal with email accounts.
  • Prepaid credit billing through Stripe, with a hard stop when the balance runs out.
  • A pricing page with tiers, plus referral codes redeemable after signup.
  • Every charge is recorded in a usage ledger you can export.
  • Read-only billing endpoints available with an API key.
Feature

Custom Prompts and Per-Job Feedback

Tell us what a conversion got wrong on the job that got it wrong, with custom prompts managed in one place.

  • A per-job feedback thread in a floating widget — the report stays attached to the job it is about.
  • Custom prompts managed from a central store rather than edited per deployment.
  • Presentations convert through PDF, so slide decks keep their layout.
v1.7.0Feature

Conversational Analysis Rebuilt, Spanish, and Session Security

A rebuilt conversation surface with a proper citation viewer, Spanish end to end, and sessions hardened to enterprise expectations.

  • Conversational analysis rebuilt: a citation viewer with page navigation and full-screen reading, sources grouped by kind, and Excel, Word, CSV and text rendered inline instead of downloaded.
  • Scope a conversation to part of the data room with a file picker, or query the generated reports instead — Specter’s own outputs appear as files you can filter on.
  • Chat sessions persist, with suggestions on the empty state and a rolling summary that keeps long conversations coherent.
  • Spanish added end to end, alongside Japanese and English.
  • Library management with versioning, a slide view for business analysis sections, and charts enriched in the background and regenerated selectively.
  • Sessions moved to httpOnly cookies with CSRF protection, rate-limited authentication, and detection of refresh-token reuse.
  • GDPR data-subject endpoints (Articles 15, 17, 20 and 30) and SOC 2 logging, monitoring and admin accountability.
v1.6.0Feature

Shared Engine, Project Dashboard & Shared Links

Analysis moved onto the same document intelligence engine Nebula runs on, with a project dashboard and links you can send outside the account.

  • Analysis generation moved onto the shared engine Specter and Nebula both build on, so a document is parsed once and reused across every analysis.
  • A project dashboard summarizing library state, processing progress and analysis coverage in one place.
  • Shareable section links, so a finished section can be sent to someone without an account.
  • A reference library selector, to scope an analysis to a chosen subset of documents.
  • A chat scope selector: query the data room, the generated reports, or both.
  • Red Flags export questions and DDQ request data, plus a project context dialog captured after upload.
v1.5.1Improvement

Search Variants, Pagination & Red Flags

Smarter Japanese search with automatic name variants, pagination across data listings, and improved Red Flags accuracy.

  • Search now generates kana, romaji, and abbreviated name variants automatically for more comprehensive results across Japanese data sources.
  • Pagination and search history added to Registry and other data-heavy views.
  • Prefecture-based filtering and ranking for Nenkin and Kanpo results.
  • Table of Contents sidebar with auto-scroll for long CDD reports.
  • Red Flags analysis prompts improved to reduce false positives.
v1.5.0Feature

Full Web CDD workflow, a new Registry module for Japanese compliance records, and a reorganized Data Room.

  • Web CDD: run competitor due diligence with citations, table of contents, summary views, and export to data room.
  • Registry: search Nenkin (pension registry) and Kanpo (government gazette) records for target companies.
  • Classification and structure tree redesigned — creating a project now auto-generates its structure.
  • Red Flags and Teaser Analysis now support running multiple independent analyses.
  • Data room reorganized into Uploads, Outputs, and Registry tabs with folder tree view.
v1.4.1Improvement

v1.3.1Fix

Excel Processing & Stability

Fixed Excel, XLS, and CSV processing to handle empty cells and formulas correctly. General stability improvements.

  • Formulas stripped from Excel files before analysis to avoid misleading content.
  • Trailing empty rows and columns trimmed to reduce unnecessary processing.
  • Improved error handling and timeout management for large document sets.
v1.3.0Feature

Gemini as an alternative model for analysis, and faster document processing.

  • Gemini model option added alongside OpenAI for analysis.
  • Document processing optimized with batched status updates and reduced token usage.
  • Interdependency analysis across sections for deeper structural insights.
v1.2.1Improvement

Citations now link to specific page numbers in source documents. Processing reliability improvements.

  • Analysis citations include page numbers so you can verify sources directly in the original document.
  • Improved processing progress percentage accuracy.
  • Page-level document classification for more granular content categorization.
v1.2.0Feature

Data Room, Presentations & Teaser Analysis

Centralized data room for all project files, PowerPoint generation from analysis results, and Teaser Analysis.

  • Data Room: organize uploads, outputs, and downloaded files in a folder hierarchy with search, rename, and bulk operations.
  • Generate and download PowerPoint presentations from your analysis — per section or full report.
  • Teaser Analysis for quick preliminary assessments, with timestamped history.
v1.1.1Improvement

  • Business Analysis module with end-to-end workflow: structure generation, document classification, section-by-section analysis, and report view.
  • Editable structure tree — add, remove, and reorder sections before running analysis.
  • Analysis results appear as they are generated instead of waiting for the full run to complete.
  • Export results as Excel spreadsheets or download as ZIP.
