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. Oct 18, 2026 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.

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. Oct 12, 2026 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. Sep 30, 2026 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. Sep 30, 2026 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. Sep 11, 2026 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.

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. Jul 30, 2026 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. Jul 24, 2026 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. Jul 15, 2026 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. Jul 14, 2026 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. Jun 30, 2026 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. Jun 10, 2026 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.
