Mention an idea once and Synapse wires it to every note that touches it. No tagging, no folders.

[ SURFACE ]

Forgotten notes, resurfaced

Your graph is weighted by what you revisit. The threads you've let go of tug back at the right time.

[ ASK ]

Question your own graph

Ask in plain language and get an answer stitched from your notes, with every source one click away.
