Folio turns PDFs, scans and photographed pages into clean, editable Markdown. Recognition runs entirely on your machine, so your documents never leave it.
Contracts, research papers, receipts, book chapters and forms — recognized page by page, with the structure kept intact.
Recognition happens locally. Nothing is uploaded, queued on a server or shared with anyone. After setup, Folio works with no internet connection at all.
Everything runs on your own hardware, so nothing meters your use. Import a one-page form or a five-hundred-page report.
Multi-column layouts, tables, mathematical formulas, charts and stamps are reproduced as structured Markdown instead of one flat line of text.
See the original page beside the recognized text, step through pages, and edit anything that came out wrong. Your corrections are kept.
Each finished page is saved immediately. Close the app or restart the computer mid-document and Folio resumes from where it stopped.
Save results as Markdown, plain text, HTML or JSON, one document at a time or in batches, into any folder you choose.
Three steps, then it is yours to use offline.
On first launch, Folio shows you the recognition engine and model it needs, along with their size, and waits for you to confirm before downloading anything.
Choose PDFs or images from your computer. Folio reads them page by page and shows the text appearing as each page finishes.
Compare each page against the original, correct anything you need to, then export the finished document in the format you want.
Straight answers about privacy, requirements and cost.
No. Recognition runs entirely on your own computer. Your files, the recognized text, your edits and your settings all stay in a folder on your local drive, and Folio does not transmit document content anywhere.
No. There is no account, no sign-in and no subscription. Install the app and use it.
Yes, once set up. The only step that needs a connection is the initial download of the recognition engine and model files. After that Folio runs fully offline. It can optionally check for engine updates, but only when you ask it to.
No. Because processing uses your own hardware rather than a paid service, there is no monthly quota and no per-page charge. The practical limits are your disk space and how long you are willing to wait.
Folio is free to download from the Microsoft Store. There are no in-app purchases and no subscription.
PDFs and common image formats, including scans and photos of printed pages. Folio reads the page as an image, so scanned documents without a text layer work the same as digital PDFs.
Windows 10 version 1809 or later, 64-bit. The engine and model files need several gigabytes of free disk space. At least 8 GB of RAM is recommended; more memory and a faster processor make recognition quicker.
Accuracy depends on the scan quality and how complex the layout is. Nothing is perfect, which is why Folio shows every page beside its original so you can check it. You can edit the text directly, or re-run a single page without disturbing the rest of the document or losing corrections you made elsewhere.
The interface is available in English, Simplified and Traditional Chinese, Japanese, Korean, French, German, Spanish and Italian. Text recognition covers considerably more languages than the interface itself offers.
