## What is fork ai?

Upload your lecture PDF and fork ai turns it into a mind map of notes.
Then dig into any part of it: open a branch on the map, or tap a sentence and Ask AI about exactly that.
Every question becomes a branch on your map, so you can find your place again.

HOW IT WORKS
• Upload a lecture PDF (lecture slides saved as PDF are fine), a text file, a Markdown file or an image
• fork ai builds a mind map of notes from it
• Open any branch from the map to read it
• Tap a sentence, or highlight a passage, and tap Ask AI to ask about exactly that
• Each answer becomes a new branch on the map
• Mix several branches into one new answer with the Mixer

KEEP AND SHARE YOUR WORK
• Highlight in colors and pin callouts
• Export a session to Notion as a structured page
• Share a session with a link. Anyone can read it without an account
• Choose the AI model for each branch
• Turn on web search to get answers with cited sources
• Get a notification when a long research run finishes

BEFORE YOU UPLOAD
• fork ai reads up to 50 pages, or about 40,000 characters, of a file
• Scanned PDFs with no text layer are read by OCR: the first 10 pages only, and English only
• If a file was only partly read, the app tells you, so you can split it and upload the rest
• You need an account to upload. Sign-up is free

CREDIT
New accounts get a one-time $5 starting credit. AI answers use up credit. When it runs out, you can buy more inside the app.
