A desktop sidebar that gives AI assistants a memory that does not collapse: reusable knowledge buckets instead of one ever growing context window.

01 Architecture

• Electron shell in TypeScript, with SQLite as the local store so nothing leaves the machine.
• Knowledge is authored once into named buckets and reused across assistants, rather than re-pasted per conversation.
• Selective context injection picks only the buckets a given turn needs, which is what keeps prompts small.
• Real time analysis of the running conversation decides what is worth injecting next.
• Adapter layer so the same buckets serve 3+ different assistants.

02 What is in it

• Solved context window bloat across 100+ chats.
• Adopted by 8+ teammates and presented at internal AI meetups.
• Built as an internal tool while at Amazon, so there is no public build.
