Scans, paper PDFs, and lecture notes with formulas need to become editable text — without standing up inference yourself. MiniCPM OCR (minicpmocr.com) is a ready web workbench based on OpenBMB’s open model MiniCPM-OCR 1.0, but the site itself is an independently run SaaS, not the ModelBest / OpenBMB official console. Upload image or PDF → proof against the original → export Word / Markdown / JSON. Researched October 29, 2026.
First: independent site ≠ official
The site FAQ is clear: the website, accounts, subscriptions, and document flow are deployed by the operator (copy mentions Cloudflare Workers, D1, private R2); OCR inference goes through their servers to the ModelBest API — weights do not run on the operator’s Cloudflare. Official model card on Hugging Face: openbmb/MiniCPM-OCR-1.0; official demos and API are via ModelBest / OpenBMB channels. This article covers this independent web app’s usage and pricing — do not confuse it with the official playground.
Upstream model notes (from the model card when checked): ~1.3B parameters, Apache-2.0, Chinese/English document parsing (text / tables / formulas, etc.); the card lists Real5-OmniDocBench and similar scores — treat HF as source of truth, we do not invent a comparison table. When checked, HF showed ~261 likes; model created October 21, 2026, still updating recently.

Workflow and how it sits next to tools on this site
Three steps: upload → after recognition, click original regions / result blocks to proof → export or copy a slice. Fits reports, invoices, scanned book pages, and lecture notes with LaTeX formulas. If you only want offline-in-browser PDF annotation with no upload, see PDF Tool; to truly open and save Office files on the desktop, see GenOffice; the OpenBMB-ecosystem agent workspace is PilotDeck 2.0. After structure extraction, continue AI edits on Markdown with Textus.
Who it is for (and who should skip)
Good fit: a few scanned pages that need an editable draft; accept cloud inference and independent-site billing; want side-by-side proofing before export.
Skip for now: confidential files that must not leave your network — self-host MiniCPM-OCR or use pure offline tools; need “official ModelBest billing and SLA” — use the official console; expect the free tier to carry production traffic — free is only 1 document ≤ 3 pages.
