Opennote – Personalized Learning, Perfected

In plain words

Opennote is a learning platform designed to help users personalize their educational experience. The tool applies the Feynman Technique, a learning method that emphasizes explaining concepts in simple terms to deepen understanding. It's built for students and self-learners who want to improve how they absorb and retain information. The platform focuses on making personalized learning more effective through structured, concept-based study approaches.

The notebook that thinks with you.

On May 6, 2026, we announced that Opennote has been acquired by Reducto . Everything we learned building a notebook that helps people make sense of scattered information is now going into Reducto's work on document intelligence, helping people and agents understand and act on complex information at a much larger scale. As part of that transition, Opennote has been sunset and the app is no longer available. If you need a copy of your data or have any questions, email us at [email protected] and we'll help you out directly. Thank you for trusting us with your notes, your knowledge, and your learning. Building Opennote was incredible, and we're excited for what'sfrom opennote.me

  Tetris in a PDF▲1,289

  I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

  21st.dev▲1,211

  I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
