## Documentation

# Deploy and Host Mosaic on Railway

Mosaic is a WhatsApp chief-of-staff: type `/sotu`, `/pending`, `/stats`, `/recap`, `/eli5` in **any** group and the answer is delivered privately to your own "Message yourself" chat — the group you typed in is never written to.

## About Hosting Mosaic

One Docker container (Go WhatsApp bridge + Python command engine) and one Railway volume mounted at `/data` — attached automatically by this template — which holds your WhatsApp pairing and message history across redeploys. Keep the service at one replica.

## Why Deploy Mosaic on Railway?

- Volume, restarts, health checks and the public URL are configured for you.
- Nothing else to install: pairing and settings happen from the browser once, then from WhatsApp (`/help`).
- Owner-only commands; answers never post into groups.

## Common Use Cases

- Operators sitting in 30–100 WhatsApp groups who lose track of what people asked them.
- A daily `/pending` open-loops ledger grouped by who owes what — in your Me chat.
- Catching up on a noisy group with `/recap` without posting anything into it.

## Dependencies for Mosaic Deployment

No external dependencies beyond your own accounts. At deploy time you will be asked for exactly two things:

| variable | what to enter |
|---|---|
| `GEMINI_API_KEY` | a Gemini key from a **billing-enabled** project: https://aistudio.google.com/apikey |
| `SETUP_PASSWORD` | a password for the web pairing page (used once, to scan the QR) |

Timezone defaults to `Asia/Kolkata`; add a `TZ` variable later if you need another.

After deploy: open the service URL, log in with `SETUP_PASSWORD`, scan the QR under WhatsApp → Linked devices, wait for **Connected as +91… · Me chat: …**, then type `/pending` in any group. Tips and troubleshooting: https://github.com/sameer-hoda/wa-slash-commands/blob/master/docs/RAILWAY.md
