Give it the task.
It makes the call.
Mishu is a phone assistant that runs on your own computer. Tell it what to find out and it calls, asks, and brings back the answer. It picks up when someone calls you. And any AI you already use can drive it.
macOS first; Windows and Linux next. The engine also runs headless on a server.
Three ways a call starts. One place it all lands.Example · one ordinary afternoon
- You give it a task
“The kitchen tap is leaking. Find five plumbers near me, ask who can come Thursday morning and what the call-out costs.”

Open source · agent-driven
Open source.
Any AI can drive it.
The core is MIT-licensed and on GitHub. Mishu speaks MCP, so Claude, Codex, or an agent you wrote can place and answer calls through it — and never sees your Twilio keys.
- Your AI proposes, you approve. It writes the plan; nothing dials until you say yes.
- On a call it can use your tools. Calendar and your own MCP servers. Reading is free; changing needs your yes.
- Your keys stay home. Twilio and model credentials never leave your computer.

How it works
From one sentence to calls completed.
Every task follows the same visible path: you see every number and every question before anything rings, each number is called once, and the answer comes back the way you asked.
The sentence from the top of the page, turned into a plan — and nothing rings until you approve itDesktop app · example task
01
Say the task
What you want to know, and how you want it back.
02
Inspect the plan
Every number and every question, before anything rings.
03
Approve it
No call goes out until you say yes.
04
Let it call
Each number once. No answer gets a message, not a retry.
05
Get the result
Answers come back to you; so do the decisions.
Examples
Six jobs to hand it first.
Six examples, not a menu. Anything that ends in “call and find out” or “call and settle it” can be a task.
02 / OutboundWaiting on you
Move the dentist to after 2 pm.
If the office only offers days you never approved, Mishu pauses and asks you.

Example transcript · Mishu is the AIUnknown number
Mishu
Hi — I’m Mishu, an AI assistant answering for Chen. How can I help?
Caller
Is he around? It’s about the Thursday delivery.
Mishu
He’s in a meeting until four. I can take the delivery window and pass it on — what time works?
Caller
Between nine and eleven.
Mishu
Noted, nine to eleven Thursday. He’ll confirm it himself.

Coming next
And it can call you.
“Ring me at one every afternoon and tell me what came in.” Mishu turns that into a scheduled task, you approve it once, and then it calls — a real conversation you can talk back to, not a recording.

Straight answers.
Can Mishu call without asking me?
No. Plans require approval. The one exception is small question-only tasks, and only if you switch that on; you are notified and can stop them.
What happens when nobody answers?
Mishu leaves a message, records the outcome, and does not keep retrying.
Can an external agent see my Twilio key?
No. MCP lets it drive Mishu without ever receiving your credentials.
Is it really open source?
Yes. The engine is MIT-licensed at github.com/YOMOO-LLC/mishu, as a developer preview.
