Local-first persistent memory for AI assistants
The BrassNorth standard
A clear build, with a person accountable for every detail.
Useful from day one
Every page has a job: call, book, order, visit or start a conversation.
Responsive by default
Fast loading, mobile-first layouts and direct replies from Saad.
What it is
A local-first persistent memory server for AI assistants, implementing the Model Context Protocol.
The problem
AI assistants forget everything between sessions, and most memory tools send your data to a hosted service.
What I built
- Three npm workspace packages: server, core with SQLite and sqlite-vec, and a Next.js dashboard
- Two local models via Transformers.js: all-MiniLM-L6-v2 for embeddings and nli-deberta-v3-xsmall for conflict detection
- Recall blending 70% semantic similarity with 30% recency, on a 30-day half-life
- Four MCP tools
- Norn Live, an SSE fleet dashboard, added in v1.3.0
Design and engineering decisions
- Local-first with SQLite and local models, so memory never leaves the machine. That constraint set every other choice.
- Recall weights recency alongside similarity, because an out-of-date fact that matches well is worse than a newer fact that matches slightly less.
- A conflict-detection pass using an NLI model, so contradictory memories get surfaced for review instead of silently coexisting.
- The conflict pipeline measured 95% precision and 100% recall on a 32-pair test fixture.

You never have to guess the next step.
Send a short note. I will ask the useful questions, share a direction and make the decision easy.
Tell me what is stuck
Share your business, your audience and the action you want more people to take.
See the direction first
Your homepage concept comes before payment, so the fit is clear before the build.
Launch with ownership
I build in checkpoints, then hand over the domain, code and logins in your name.
