**a local, Claude-powered brain-assistant for solopreneurs**

I kept losing good ideas — not because I forgot to write them down, but because nothing ever

went back and connected them. A task on Monday, an idea on Wednesday that was secretly the

same problem, a question on Friday that contradicted something I'd decided two weeks earlier.

All of it just... sat there.

So I built **Dot Connector**: a small local app where every capture is a "dot," and every few

captures, Claude reviews the stream against a standing memory and surfaces three things —

non-obvious connections between notes, contradictions with what you said before, and open

loops you haven't closed yet.

**The architecture is deliberately simple.** It's Express + vanilla JS, no build step, no

account system. Every capture gets a cheap, fast Claude call for auto-tagging. Every 3rd

capture triggers a deeper "sweep" — a second Claude call that looks at recent captures

alongside standing memory and open loops, and returns structured updates: new memory facts,

dot-connects, contradictions, and open-loop resolutions.

**Why local-first.** no server of my own, notes never leave your machine except the direct calls to Anthropic's API, bring-your-own API key so there's no subscription — you pay

Anthropic directly, typically well under $1/month for personal use.]

**Its just a steal**
