## Minimum Setup (to test AI features)

For basic AI testing, you only need **one key**:

```bash
cd /Users/yamenahmad/projects2026/odoo/odoo19/odoo
../.conda-envs/odoo19/bin/python odoo-bin shell -c ../odoo.conf -d encoach <<'EOF'
env['ir.config_parameter'].sudo().set_param('encoach.openai_api_key', 'sk-your-openai-key')
env.cr.commit()
print("OpenAI key set.")
EOF
```

This enables: exam generation, writing evaluation, speaking evaluation (text grading), short-answer grading, and training tips.

Add AWS keys later for listening audio, ELAI for avatar videos, and payment keys when ready for subscriptions.
