The Problem

Every session starts from scratch

You re-explain your architecture. You re-describe your preferences. Your AI has amnesia.

painful
😵

Context Loss

"We talked about this yesterday." But your AI doesn't remember yesterday. Every session is a blank slate.

🔄

Re-Explaining

You paste the same architecture docs, the same coding preferences, the same project decisions — over and over.

🔎

No Search

That brilliant solution you worked out in Claude last week? Gone. No way to search your own AI conversations by meaning.

The Difference

AI without memory vs. AI with Brain Kit

night and day
Without Memory
✗ "Can you remind me what stack we chose?" — "I don't have that context."
✗ Paste architecture docs every session
✗ Decisions evaporate between conversations
✗ Each tool is an isolated silo
✗ You are the only continuity
With Brain Kit
✓ "We chose Postgres for the joins" — recalled instantly
✓ Preferences auto-loaded via semantic search
✓ Every decision persists forever
✓ Claude + Cursor + Windsurf share one brain
✓ Your AI builds on previous sessions

Setup

Live in 10 minutes

No Docker. No local servers. No infrastructure to babysit.

seriously, 10 min
1

Deploy

Create a free Supabase project. Fill in 4 env vars. Run ./setup.sh — it handles the SQL migration and Edge Function.

2

Capture

Tell your AI "remember this." Thoughts get embedded with pgvector, auto-tagged with topics, people, and action items.

3

Search

Ask "what did I decide about X?" from any MCP client. Semantic search finds it by meaning, not keywords.

Comparison

vs. Building It Yourself

Only 8 repos in the Supabase + pgvector + MCP space. None production-ready. Brain Kit is.
