Note2Agent

Send circled questions from tablet notes to AI agents on your desktop

Problem
While studying, people scribble, draw and circle questions on a tablet and then switch to a chat window to explain the context to AI, shuttling back and forth. The author of a tablet note app openly asked which handwritten-plus-AI scenarios are actually useful, a sign that no accepted workflow exists yet.
Solution
A lightweight bridge: select a handwriting area or PDF annotation in a tablet note, tap once, and the screenshot, OCR text and surrounding context go to a paired desktop agent such as Claude Code or Codex. Results come back to the note page as reference cards.
Users
Students, researchers and creators who take tablet notes and annotate papers or PDFs
MVP
One-tap region select and send from tablet; desktop pairing and task queue; invoke local or cloud agents; write results back as note cards; locally encrypted connection credentials
Revenue
Open-source core free; hosted pairing and relay subscription at $5/month; per-seat team plan
Why now
Both tablet handwriting and desktop agents have matured, and the dispatch channel between them is missing, so a bridge can win from both sides
