Broker email pipeline demo

Interactive flow: paste a broker email body → Parse with AI → review JSON, deal record, rent comps (subject row from the parse), and a screening memo. Steps 2–5 stay locked until parsing succeeds. There is no canned downstream data; everything after the email comes from the model response.

Run it

npm install
cp .env.example .env.local
# Add OPENAI_API_KEY to .env.local, then restart the dev server after changes.

npm run dev

Open http://localhost:3000. The path /demo redirects to /.

Using the demo

1. Edit the email body (default text is sample copy you can replace).
2. Click Parse with AI to call the parser, or Run walkthrough to step through the stages with a parse at the JSON step.
3. Click any step in the timeline to jump to that section.
4. Reset clears the parse and restores the default sample body.
