A small lab giving your AI hands
Melvin is one local execution layer for the AI you already use. It lets ChatGPT, Claude, Gemini and Grok find and sort your files and work in your Mac apps, on your own Mac and iPhone, only where you allow it. Your permissions, your devices, your control.
What Melvin does
Works with your files
Your AI can find files by name, kind, size or date, see what is taking up space, find duplicates and sort a folder. A clean up is planned before anything moves, each file is checked after it moves, and any change can be undone.
Works in your Mac apps
Mail, Notes, Calendar, Reminders, Contacts and Music, through their own controls: your AI can search and read, write drafts, and add events, reminders and notes. A draft waits in Mail until you press Send.
Acts when a file arrives
Tell your AI once what should happen when a file lands in a folder, approve it on your Mac, and Melvin does it each time, with no chat open.
One engine for every AI
Add Melvin to ChatGPT, Claude, Gemini or Grok as a connector. Each one reaches your Mac through one set of tools and one set of permissions, and the chat app never reaches your devices itself. How to connect.
Its own chat, too
The Melvin Mac app also has a chat of its own, for when you would rather ask Melvin directly. It works in your Mac apps, runs web tasks in a cloud browser it operates, and can repeat a run on a schedule.
What makes Melvin different
It starts when a file arrives
An automation watches the folders you choose and runs when a file lands or changes, as well as on a schedule.
It does not need a chat open
Melvin runs from the menu bar on your Mac, so automations, and tasks your AI already sent, carry on with the chat closed.
It checks its work
Each action reports what really happened, each folder and each app has its own permission, every task is logged, and file changes can be undone.
Your files stay on your Mac
Finding, comparing and moving files happens on your Mac. Your AI sees names, sizes and dates, not what is inside the files.
It never takes over your screen
Melvin works without bringing apps to the front or moving your cursor, so you keep typing while it runs.
Who uses Melvin
- People who already ask ChatGPT, Claude, Gemini or Grok for help and want it to act on their own Mac.
- Founders and operators at small companies whose day runs through Mail, Calendar and a folder of documents.
- Freelancers and consultants who file, invoice and follow up on their own.
- Anyone with a job they repeat by hand each time a file arrives: an invoice, a report, a scan.
- People on Apple silicon Macs running macOS 14 or newer.
The team behind Melvin
We started Melvin in 2026 because the tools that were supposed to save us time made us type more, not less. Melvin gives the AI we already use the hands we wished it had, so it does the work instead of describing it.
The team is two people who build, ship and answer support themselves, shipping every week. The goal is work you do not have to ask for twice, and we would rather say that out loud and be measured against it.
How Melvin works
Getting started
Download Melvin, drag it into Applications, open it and sign in, then add it to your AI from the Connect page. macOS asks once for the accessibility permission Melvin needs to read your apps, and the download page walks through it.
What a task looks like
You ask your AI. Melvin checks you allowed it, your Mac does the work, and your AI gets back exactly what happened. Anything that cannot be undone waits for your confirmation, and every task lands on your Activity page so you can check what it did.
Who you talk to
Support is the team that builds Melvin. Email support@trymelvin.com and a human replies within one business day; security reports to security@trymelvin.com are acknowledged within 48 hours.
What ships
New releases go out every week. The release notes list what changed in each one.

Frequently asked questions
Who makes Melvin?
Melvin is built by a two person team that ships every week. Every piece of feedback is read by the people who write the code.
Which AI apps work with Melvin?
ChatGPT, Claude, Gemini and Grok, and Meta’s Muse too. A ChatGPT dot can use Melvin as well wherever ChatGPT lets dots use your connectors.
Is Melvin free?
Yes. Free needs no card and covers everyday use on one device. Pro adds all your devices, unlimited automations and scheduled checks, every connected account, app control and running Shortcuts, from $4.99 a month or $39.99 a year.
Does Melvin send my screen to a server?
No. On the Mac, Melvin reads the accessibility structure of your apps, which is text rather than images, and that stays on your Mac. Web work in Melvin’s own chat runs in a browser Melvin operates in the cloud, and every run says which lane it used.
Will Melvin do things without asking?
Anything reversible just runs. Anything that cannot be undone, like a sent email, a booking, a deleted file or a payment, waits for you to confirm it.
Does Melvin work on Windows or Intel Macs?
Not today. Melvin runs on Apple silicon Macs with macOS 14 or newer, and Windows comes after.
