Hands for the AI your team already uses
Melvin lets the AI each person already uses, like ChatGPT, Claude, Gemini or Grok, work on their own Mac: their files and their Mac apps, with their own permissions and a record of every task. The Melvin Mac app also has a chat of its own, which can do the work below.
What Melvin handles
Inbox triage and drafts
Searches connected Gmail or Apple Mail, summarizes threads, and drafts replies for your review. Sending asks first.
Calendar that defends focus
Reads Apple Calendar, finds open time, and prepares new events on your Mac. Invites that include other people ask first.
The web, in a cloud browser
Fills forms, pulls text and works through multi-step flows on sites, in a browser Melvin operates in the cloud. Sign in once inside a run and it stays signed in.
Notes, files, and iMessage
Write Notes, find files, manage Reminders, read iMessage threads. Sending a message asks first. WhatsApp is not supported.
Slack and Google Docs
After a one-time connect under Settings → Your apps: catch up in Slack, post (asks first), find and edit Docs sections (writes ask first).
Auditable output
The Activity view records runs and their outcomes so you can inspect what Melvin attempted.
Why people pick Melvin for work
Your team’s AI can already think. Melvin gives it hands on each person’s Mac: it finds and sorts their files, drafts the reply and holds the calendar block, then stops before anything permanent, which each person approves in their own AI app. Every task is on their Activity page.
Mac work never leaves the Mac. Web work runs in a browser Melvin operates in the cloud, and every run says which lane it used. Model requests carry the minimum context a task needs.
