PersonalBrain — Web UI

This adds a tiny Flask-based web UI to run your local assistant. It uses your existing brain.py logic and vector search.

Files added:

• app.py — Flask server with / UI and /api/chat endpoint
• templates/index.html — simple chat UI
• static/chat.js — frontend JS to call the API
• static/style.css — UI styles
• requirements.txt — Flask dependency

How to run (Windows PowerShell):

1. Activate your virtual environment (from the project root):

.\venv\Scripts\Activate.ps1

2. Install requirements (only needed once):

pip install -r requirements.txt

3. Start the server:

python app.py

4. Open http://127.0.0.1:5000 in your browser and ask questions.

Notes:

• The server imports brain.py to reuse its search, format_context, prompt, and model objects. Ensure brain.py works standalone.
• If you run into import errors, confirm your venv is activated and required packages are installed there.
