Recho Notebook: A Text-First Notebook Built with Observable Notebook Kit

Show and Tell
1

Hello everyone! Luyu CHENG and I built Recho Notebook on top of Observable Notebook Kit, and it was accepted as a CHI 2026 Poster! So we’d love to share it here. Recho Notebook is a text-first notebook environment where output appears inline as comments, so code and feedback stay in one flow.

Below is a quick demo. You can find more details in the docs, examples, and this announcement post. Recho Notebook is also part of my thesis work, so I’d really appreciate any feedback, suggestions, or questions.

Thanks Tom! I think the Observable team did a great job making their system reusable!
