# OsmO — AI phone assistant for iPhone & Android (full reference)

> OsmO is a personal AI phone assistant that makes calls for you — booking reservations, appointments, and follow-ups — and answers your calls when you can't, taking a message and texting you a transcript. It also handles unknown callers, so spam and robocalls are caught before they reach you. It runs on top of your existing phone number using conditional call forwarding — no new number, no SIM swap — and is free to download on iOS and Android. Maker: Mountainheads Private Limited.

## About OsmO
OsmO acts like a personal assistant for your phone, working in both directions. It makes calls on your behalf — booking a table, confirming an appointment, or chasing a refund — and it answers your incoming calls in a natural-sounding voice when you can't, finding out who's calling and why, then taking a message or putting important callers through. You stay in control: the calls that matter reach you, and spam and robocalls don't.

Everything is written down: OsmO transcribes and summarizes every call so you can read instead of listen. It also includes an in-app AI chat assistant you can use to give instructions and ask OsmO to place calls for you.

## How OsmO answers your calls
1. You forward unanswered/unknown calls to OsmO using your carrier's conditional call forwarding (set up once, in about a minute).
2. When an unknown number calls, OsmO's AI answers and has a short, natural conversation to learn who's calling and the reason.
3. OsmO decides in real time: connect the call to you, take a message, or block it as spam/robocall.
4. You get a notification with a transcript and summary, and can call back or reply from the app.

## Outbound calling
OsmO can place calls on your behalf for routine tasks such as booking appointments and reservations or confirming details, then reports back what happened in plain text.

## Spam & robocall blocking
OsmO screens unknown callers conversationally, so spam and robocalls are caught before your phone rings. Unlike a static block list, the AI evaluates each caller in the moment.
