ThinkerNotes

ThinkerNotes lets users capture one-line insights quickly, refine them into their own conclusions, and link them to older related notes. It surfaces relevant past notes in context, supports importing Kindle highlights, lets users search notes by meaning, and offers an MCP connection so Claude or other agents can search the user's own insights. Users can create shareable images from notes for LinkedIn, X or Instagram. The site states it is free to start with up to 100 notes, and a Pro plan removes the note limit and adds Kindle import and custom branding on shared images.
