Claude gets semantic memory. Remembers across sessions. Finds connections you missed.

How it works

you › "Our auth uses JWT RS256, tokens expire in 15min"
khorai_remember → stored (node 1)
... new session, next day ...
you › "I need to add a refresh token endpoint"
khorai_recall "auth token" → node 1 (0.94)
Claude already knows your auth setup. No re-explaining.
you › "What am I missing?"
khorai_blind_spot
"No memories about error handling or logging strategy.
 Auth + payments exist but no rate limiting mentioned."
