Opennote

The notebook that thinks with you.

What Opennote does

Opennote is a notebook with an AI thinking partner built in. Feynman lives in your work: it edits your writing, references your knowledge and the web, runs background tasks, and gives feedback as you work.

No open roles recorded right now.

That does not mean they are not hiring — plenty of roles never reach a job board. The careers page below is the earliest place a new opening appears.

Check the company’s own careers page — linked at the top — before a job board. A role appears there first, sometimes weeks before it is syndicated anywhere else.
