Opennote

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

Visit opennote.com ↗

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.

What it's for

  • Search personal study notes for relevant context and automatically append new explanations
  • Generate structured daily study plans and practice problems based on current notes
  • Synthesize scattered personal research into cohesive journal entries

Features

  • In-journal AI editing that directly writes into user documents
  • Step-by-step inline action citations showing search and reading progress
  • Personalized study plan recommendations based on existing knowledge
  • Flashcard and practice problem generation
  • Collaborative digital notebook workspace

Why it was saved

  • @DhravyaShah, 26 January 2026: 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.
