ThinkerNotes

What you work out stays worked out

Frictionless capture

One sentence, however it comes out, is the whole commitment — no title to invent, no folder to pick and nothing to decide before you write.

Linked insights and follow-ups

ThinkerNotes shows older notes that relate to what you are writing and you link the ones that belong, building trails from first hunch to decision.

Contextual resurfacing

Instead of waiting for you to remember to look, it puts the note you wrote last year next to this week's problem so you build on your own thinking.

Works inside Claude and ChatGPT (MCP)

Connect once from your assistant's settings and it answers from what you actually concluded rather than the internet's average opinion — read-only, so it can never edit your notes.
