Business Brain: a private AI that reads your files first

A private AI for a real estate team. It reads the team's own files before every job and saves each correction for next time.

Problem and fix

What was broken.

before

Every ChatGPT chat started from zero, so the owner explained the business, the buyers and the tone again and again.

after

One folder holds the facts, SOPs, scripts and past corrections. The AI reads it first, and every correction is saved.

Watch it work, 30 seconds

One lead, from the first message to the owner's dashboard. Sample data.

My role

Designed the folder structure and the playbooks, and built the interactive demo.

01Keep the brain as plain files on the owner's computer, so it stays private and moves with them.
02Split it into core, operations, sales, voice, skills and memory, so each job reads only what it needs.
03Save every correction to one file the AI reads before every draft.
04Stop at a draft. Nothing is sent without the owner's yes.

How it is wired

Built with Claude Code or Codex, Markdown files, Airtable and voice dictation.

Result

Four real jobs: a lead reply, a listing, a call brief and an agent scorecard.
Correct the lead reply once, and the listing written next already follows the rule.
The demo runs in the browser on sample data.
