Think on paper. Work everywhere else.
You shouldn't have to choose between thinking well and getting things done. Margen transcribes every page you write on your Boox and delivers it to Claude, ChatGPT and Notion. You keep the pen; your ideas stay within reach.
Claude
ChatGPT
NotionClaudeChatGPTNotionYour best thinking happens on paper. Then it gets stuck there.
The tablet is a wonderful place to think. It's a bad place to find anything later. Search stops at the device, recognition struggles with real handwriting, and nothing reaches the tools where your work actually happens.
“Manually exporting files, converting formats, and copy-pasting text like it was 1999.”
“Roughly as organized as napkins shoved in your glovebox… if you need a specific one, well, good luck.”
“[My DIY integration] ended up being too unreliable for real-life use.”
Keep the pen. Lose the retyping.
Claude
Meetings / 1:1 SamEverything your notes need, in one app.
Reads real handwriting.
Each page is read as an image by a state-of-the-art vision model, which copes with quick handwriting, abbreviations, lists and arrows. When a word matters, Claude opens the page image to check.
Ask your notes anything.
Connect Margen once from Claude’s connector directory, or in ChatGPT, and ask about any page from the web, the desktop or your phone. Notion is next.
Bring your old notebooks.
Import the notebooks you wrote in Boox Notes. Their pages are transcribed and searchable like the rest; each page counts as a new note.
Find any page again.
Every page gets a short title and a summary. Search goes through your handwriting and the summaries, so the page turns up even when the word was hard to read.
Writes as well as Boox Notes.
Ink appears under the pen tip with no lag. Pressure, palm rejection and the eraser end work as you expect, and the refresh is tuned for E Ink.
Your notes stay yours.
The connector is read-only. Pages are transcribed with zero data retention and never used to train models, stored encrypted, and deleted from the server when you delete them. App privacy policy.
See it work.
A page written by hand on a Note Air. Margen syncs it and names it, then Claude reads it, does the math, plans the next steps and puts the plan in Notion. Real recordings, sped up where it's slow.
In their words.
“I was making notes on Linux and using them to make flash cards for studying and memorizing various commands! I was originally trying out Boox built in tools but didn’t find them robust enough! With Margen I was able to transcribe my notes and then Claude also made me a set of flash cards from those notes!”

Before you join.
Which tablets does Margen work on?
Boox tablets running Android 10 or later. Early access goes through a Google Play closed test. If you have another tablet, pick “Another tablet” in the early-access form and tell us which one.
Does Margen read the notes I already have in Boox Notes?
Yes. In Margen, open Settings → Boox Notes and pick the notebooks to import. Their pages come in as read-only pages, are transcribed and become searchable from Claude like the rest. Each imported page with writing counts as one new note from your monthly allowance.
How do I connect Claude?
Margen is in Claude’s connector directory. In Claude, open Customize → Connectors → Browse connectors, search for Margen and click Connect. Sign in with the email you use in Margen: type the 6-digit code you receive, then Allow. The connector then works in the Claude web, desktop and mobile apps. It is read-only and you can disconnect it at any time.
How good is the handwriting recognition?
Each page is read as an image by a vision model, which copes with quick handwriting, abbreviations, lists and arrows. Like a person, it can misread a word: when it matters, Claude opens the page image to check.
Is Margen really free?
Yes. Every account can write up to 100 new notes a month for free, and an account you open now stays free: we won’t take the free plan away or shrink it later. Pro, $49 a year, is for people who write more and removes the limit.
What counts as a note?
A page counts as one note the first time it is transcribed with something written on it. Blank pages are free, and editing a page later doesn’t use another note (up to 100 re-transcriptions a month).
Does it work offline?
Writing works offline. Pages are transcribed and become searchable once the tablet has a connection.
