# Opennote

> AI notebook that reads, writes, and plans inside your notes

Opennote was an AI note-taking and learning tool built to act as a collaborative thinking partner. Rather than existing merely as a chat sidebar, it searched your existing notes, updated content directly, and suggested personalized study plans. The product has been sunset following its acquisition by Reducto.

## Why it was saved

- [@DhravyaShah, 26 January 2026](https://x.com/DhravyaShah/status/2015869929162256427): Saved for the product itself: a memory-driven AI that reads and edits the user's own journal rather than just chatting. Notable that the team behind it is reportedly just 3 people.
