OsmO is a personal AI phone assistant for iPhone and Android. It answers calls you cannot take, screens spam and unknown callers, and sends transcripts and summaries so you can respond with context. OsmO can also make outbound calls for everyday tasks such as booking appointments, checking availability, chasing refunds, following up, and waiting on hold. It works with an existing phone number through call forwarding, so users do not need to replace the number they already share. Owners can add business knowledge, choose a preset, character, or custom voice, and set rules for urgent-call transfers. OsmO is available in the United States, United Kingdom, and Canada. It is free to download, includes a seven-day trial, and offers an optional Pro plan.
