Jawab: AI Call Assistant

Jawab answers your phone for you. When a call comes in, an AI voice picks up, talks with the caller naturally, and hangs up when they're done. Every call is saved with a transcript.

FOR YOUR BUSINESS
Salon, clinic, restaurant, gym, coaching class or shop: tell Jawab your hours, your services or menu, and what callers usually ask, or take a photo of your menu or price list and let it fill them in. It answers as your receptionist, using only what you wrote.
- Books appointments and tables at times that are really free, and writes them into your calendar. Pick your Google calendar and bookings show up on your own phone.
- Respects your calendar: anything you block out there is never offered.
- Lets callers check or cancel their own bookings, and books spots in your weekly classes.
- Turns enquiries about prices, stock or packages into leads for you to call back.
- Can wait for your OK on each booking, from the notification.
- Politely turns away sales and loan calls, and can answer only while you are closed.
- Takes a message when it doesn't know something, and tells you with a notification.
- Speaks the languages you choose, and switches to the caller's language.

YOUR NUMBER, YOUR PHONE
No call forwarding, no new number, no server of ours. Put your SIM in an Android phone, turn Jawab on, and calls to your usual number are answered. Choose who it answers: everyone, your contacts, or a list of numbers, and how many seconds to wait so you can still pick up yourself.

HOW IT WORKS (PLEASE READ)
Android doesn't let ordinary apps hear or speak into a phone call. Jawab uses Shizuku, a free app that gives it the same access a connected computer has, without root. You start Shizuku once with Wireless debugging, and again after the phone restarts.
The AI voice is the service you choose: Google Gemini (recommended), Sarvam AI or xAI Grok. You use your own API key for it; Gemini keys are free from Google AI Studio. A Line test voice, which needs no key, lets you check that callers hear Jawab before you add one.
Some phones need a different audio route; Jawab checks your phone and you can switch it in Settings.

PRIVACY
Callers are told an AI is answering. The call's audio goes to the AI service you chose so it can understand and reply. Transcripts, bookings and messages stay on your phone. Jawab has no account, no ads and no analytics.
Contacts are read to greet callers by name and to answer only them if you choose. The calendar is read and written to book free times. Both are asked for with Android's own permission dialogs, and both are optional.

Jawab answers one call at a time. Recording or answering calls with AI may need the caller's consent where you live; Jawab always announces itself.
