Decision memory for developers

Your coding agent forgets why — Neither remembers the decision and cites it.

Push docs you choose, connect MCP in Cursor, and ask why — with cited decisions instead of pasted notes or confident guesses.

Stop your AI serving confident soup — accurate, consistent, cited context, every time.

Decision memory where your agent works

Coding agents forget why a path was chosen. Neither keeps cited decisions, owners, and rejected approaches tied to the files you push — not pasted notes.

Cited why, not confident soup

When you ask why in Cursor, memory_for_file returns structured citations with provenance — scoped to your business context and the docs you chose to push.
