My Side Call

My Side Call makes real phone calls in English for people who'd rather not — and lets Meta Muse make them for you. I'm a Korean immigrant in New Jersey. Like millions of non-native speakers, I put off phone calls: the clinic, the cable company, the solar guy. My Side Call is the fix. You type what you need in your own language (Korean, Spanish, Japanese, Chinese or English), and an AI makes the actual phone call in English. It introduces itself as an AI assistant, follows your request, and — this is the part that matters — stops and asks you, on your screen, in your language, whenever something comes up that you didn't cover (a different time, an extra fee). When the call ends you get a brief in your language, the recording, and a clean transcript. During the hackathon I turned My Side Call into a phone for AI agents. It now runs an MCP server, so any agent — Meta Muse, Claude, your own — can place calls, follow them, answer the AI's mid-call questions, and even call you (wake-up calls, reminders, results). I registered it as a custom connector in the Meta Muse app, so you can simply tell Muse, in Korean, "call them back and cancel it." The demo video is a real call. On Sunday Nov 1 a solar consultant was due at my house at 2 pm and I wanted out. I asked Muse in Korean. The AI sat through two minutes of hold music, pressed 1 for the voicemail queue, got a human agent, disclosed it was an AI calling on my behalf, gave the number on file, and got the appointment canceled with email confirmation. Muse reported back: "Canceled. The agent confirmed it herself. No need to pretend you're not home." (Address and phone number are bleeped in the video; the agent's voice is pitch-shifted.) What's new since Oct 26 (all marked in the README table and visible in git log --since=2026-10-26): the Muse Spark call brain and multilingual brief, bill-photo reading with Muse Spark vision, Muse Voice re-transcription, Facebook Login, the MCP server + agent keys, "Ask Muse", owner calls, the Meta Muse app connector, the whole redesign (scribble mascot, paper UI, "say hi in any language" intro), free-beta limits, and the legal pages. The product existed before as a Korean-only prototype on OpenAI; everything Meta is from this week. Why it matters for Meta's world: Facebook and WhatsApp are where immigrant communities already live. A Muse that can pick up the phone — politely, with disclosure, and that checks with you before deciding — removes one of the most stubborn daily barriers for people who read English fine but dread speaking it on a call. Next: English → any language, so a Korean small-business owner's Muse can call a Spanish-speaking supplier; two people, two languages, one call. Try it in 60 seconds (judges): go to https://mysidecall.com/login?judge=1 and enter the guest access code MUSE-2026 (Facebook Login works too, but the Meta app is still in development mode pending business verification, so the guest code is the sure path). Then put your own US mobile number as the number to call, and type a request in any language ("ask if they have a table for two tomorrow at 7; if not, ask what's free"). Your phone rings, you hear the AI introduce itself, and when you name a different time you'll see its question arrive on your screen in your language. Free beta: 3 calls / 10 minutes per account, no card. Emergency, medical and legal calls are blocked by design. Live: https://mysidecall.com · Solo build by Aaron Lee.
