## call4me

call4me solves the part of an AI assistant's job that still requires a phone. Websites often cannot answer questions like a business's cancellation policy or a self-pay price, and appointments frequently have to be made by voice. call4me connects to your agent over MCP (Model Context Protocol) so the assistant can dial a business, work through phone menus, and hold for a human until the task is done.

Setup is deliberately light. You install the call4me connector in ChatGPT, Claude Code, Claude Desktop, Codex, Grok Bot, Muse or another MCP-compatible client, sign in, and then simply ask in plain language for what you need. The service finds or uses the number, asks the agent for any missing details a specific call requires, and places the call. While the call runs, the AI caller can get quick answers to mid-call questions from your agent instead of stalling the business on the line.

You stay in control of the conversation. call4me can ring your saved phone number when a business needs to verify your identity, at which point you are on the call as soon as you answer and can hand it back by pressing * or hanging up. You can also ask to join in listen-only mode and press 1 to take over. Every call is tied to a credit balance, with the maximum cost held up front and settled when the call ends.

**Pricing & Plans:** Credit-based. You load credits starting at $10 (reloads monthly unless you untick it), calls are billed at $0.25 per minute from pickup, including phone menus, at half that rate while on hold. The maximum cost is reserved up front and settled when the call ends.

- **MCP connector for your agent:** Add one URL to ChatGPT, Claude Code, Claude Desktop, Codex, Grok Bot, Muse or any MCP-compatible client and your agent can place calls.
- **Real calls, menus and hold time:** call4me dials the business, navigates automated phone menus and waits on hold, then reports the outcome back to your agent.
- **Patch-in and listen mode:** Your phone can ring when a business needs to verify you; answer to take over, or listen silently and press 1 to join.
- **Category-aware briefs:** The agent is asked for only the details a specific call requires, such as party size, visit reason or insurance status, rather than a full profile up front.
- **Transparent per-minute billing:** Credits are held up front per call and settled on completion, with hold time charged at half the standard rate.

**Strengths:** Adds genuine phone capability to the AI assistants and coding agents you already use; Handles the tedious parts of calling, including IVR menus and hold queues; You can take over or listen in, so sensitive verification stays with you; Per-minute pricing with hold time at half rate is easy to reason about

**Limitations:** Requires a credit balance before any call can be placed; Depends on the reliability of third-party MCP clients and connectors; Call quality and outcomes vary by business and by how well the brief is written

## OsmO

OsmO is an AI phone assistant that sits behind your existing phone number and deals with the calls you would rather not take. It answers unknown callers, asks who is calling and why, silences robocall and scam traffic, and texts you a transcript and summary of anything that mattered. Because it works through conditional call forwarding on the number you already have, there is no SIM swap and no second line to pay for.

The product covers both directions of traffic. On inbound calls you define rules that decide what happens: family and known contacts ring straight through, unknown numbers get a chosen assistant character, telemarketers are silenced, and after-hours calls go to a message. OsmO can also clone your voice from roughly fifteen seconds of speech so callers hear you rather than a stranger. For small businesses, the assistant reads your website, PDFs, Google Docs and Sheets, FAQs, service areas and Maps listing to answer customer questions, check availability and book jobs during the call, then confirm the slot in Google Calendar or Calendly.

OsmO is available as a free download for iPhone and Android and supports the United States, United Kingdom, Australia, India and Canada, speaking English, Spanish and Hindi with French and German listed as coming soon. A free 7-day trial is offered; after that Android users choose between Basic and Premium, while iPhone users subscribe to OsmO Pro, with Apple and Google showing the localised price before purchase. Calls are encrypted in transit and you can review, export or delete your transcripts and recordings.

**Pricing & Plans:** Free to download with a free 7-day trial. After the trial, US pricing starts around US$7.99/month on Android (Basic and Premium tiers) and about US$9.99/month for OsmO Pro on iPhone, with localised prices shown by the App Store or Google Play at purchase time.

- **Spam screening and call answering:** Unknown callers are screened automatically: spam is silenced while legitimate messages, bookings and urgent calls are passed through to you.
- **Custom call-handling rules:** Set rules once — let family straight through, have a chosen character handle unknown numbers, silence telemarketers, and send after-hours calls to voicemail-style messages.
- **Knowledge base for businesses:** Feed the assistant your website, PDFs, Google Docs or Sheets, FAQs and Google Maps listing so it answers callers from your own materials rather than guessing.
- **Voice cloning and character voices:** Read a short line aloud and OsmO clones your voice so calls are answered as you, using either your voice or one of the studio and character voices.
- **Outbound calls, bookings and summaries:** OsmO can call out on your behalf, check availability against Google Calendar or Calendly, book slots during the call, and text you a transcript and summary seconds later.

**Strengths:** Runs on your existing number, with no SIM swap or extra line needed; Handles both inbound screening and outbound calling and booking; Voice cloning and character voices make calls sound natural and personal; Answers business questions from your own website, documents and FAQs

**Limitations:** Relies on carrier conditional call forwarding, and forwarded minutes may be billed by your carrier; Supported in only five countries; iPhone and Android use different plan names, so features can differ by platform; Screening can occasionally let an important unknown call slip past, so you still need to check messages
