Metatron lives on your Mac. It hears your meetings without joining them, keeps every to-do with who asked and when, knows your calendar, email and apps, and plans your day. Ask it anything, out loud or with ⌥ Space.
People trust you with what they say in a meeting. Metatron is built so that trust stays with you.
Transcribed on your Mac
Apple's on device speech model turns calls into text. The audio never leaves your computer, and it picks the language of each call.
Your files, in plain text
Every client or project is a folder of Markdown files you own, like Northwind/To-dos.md. Open them in Obsidian or any editor.
Your choice of AI
Use your own Anthropic or OpenAI key, or a model that runs on your Mac. We never see your data.
Nothing happens without you
Every email, message, task and calendar change is a draft you approve first.
Made for people whose day is meetings
If you leave most calls with things to do and nothing to remind you, this is for you. It also knows the difference between your clients, teams and projects.

Needs a Mac with Apple Silicon and macOS 26 or later
No. Metatron records the call audio on your Mac, so nobody sees an extra attendee.
Which AI does it use?
Your own Anthropic or OpenAI API key, or a model that runs on your Mac. Your calls and notes are not sent to us.
What about consent to record?
Metatron reminds you to tell people the call is being transcribed, with a note you can paste in the chat. The law where you and your clients are decides what you need to do.
Does it work in other languages?
Yes. It detects the language of each call. English and Spanish are tested on real calls; Portuguese, French, German and Italian are supported by Apple's model.
Is there a Windows or iPhone version?
Not yet. Mac first; an iPhone companion is planned.
What if it isn't for me?
Ask for a refund any time before the first version ships, and within 30 days after.
