Use Melvin with your AI

Every AI app uses the same link:

Your AI gives you one link. On a Mac it installs Melvin from the download page; on an iPhone it gets the Melvin app. Melvin asks for what it needs there, the task runs, and you are back in your AI.

Already use Melvin? The same link connects your AI to the account you already have.

• See your Mac and iPhone: whether each one is online, its battery, and the free space on your Mac.
• Find files by name, kind, size and date, find duplicates, and see what is taking up space. It sees names, sizes and dates, never what is inside a file.
• Organize, rename and move files, and create folders, in folders you allow. A change is planned before anything moves, never overwrites or deletes a file, and can be undone.
• Move files to the Trash, after you approve it in your AI app. Put Back in Finder restores them.
• Copy files from your Mac to your iPhone, and photos from your iPhone to your Mac.
• Open apps on your Mac.
• See the names of your shortcuts, and run them on your Mac or iPhone. It gets back whatever a shortcut returns.
• Read and search your mail on your Mac and in the Gmail account you connected in Melvin, write drafts there, file messages, set up Mail rules that sort new mail after you approve each one on your Mac, and send mail, now or at a time you set, after you approve it in your AI app.
• Find, read, create and change notes in Apple Notes on your Mac, move them between folders, make folders, and save the files attached to them. Your AI app asks you before deleting a note.
• See your calendars and add or change events, and on your Mac invite people to them. Your AI app asks you before deleting an event or sending invitations.
• See your reminders, add them, complete them and change them. Your AI app asks you before deleting one.
• Look people up in your contacts, add cards, import vCards and change them. Your AI app asks you before deleting or merging cards.
• Read and search your messages and the files people sent you, see your recent calls on your Mac, and send messages, photos and files to people and group chats, as iMessage or as SMS through your iPhone, and send an iMessage at a time you set, after you approve each one in your AI app.
• Read and search the Slack account you connected in Melvin, and post or set your status after you approve each one in your AI app.
• Find, read and add to Google Docs in the account you connected in Melvin. Your AI app asks you before replacing a section.
• See and add events in the Google Calendar, and read the Google Sheets, of the account you connected in Melvin. Adding an event invites nobody.
• Search, read and query the Notion pages and databases you shared with Melvin, add to pages and create new ones.
• Search and read the Outlook mail and calendar, Teams chats and OneDrive files of the Microsoft account you connected in Melvin, write Outlook drafts and add events, and send a Teams message after you approve it in your AI app.
• List and read files in the folders you allow on your Mac, and copy, zip, tag and create text files there.
• Read PDFs, images and Pages, Numbers and Keynote files you allow, and make edited copies or add to them, on your Mac or in Melvin's folder on your iPhone, and on your Mac fill in PDF forms and make PDFs of documents.
• See which apps are open on your Mac and how long you used them, arrange their windows and quit them, or force quit one that is frozen. An app with unsaved work asks you first, and you are asked before a force quit, which loses unsaved work.
• See your open tabs, history and bookmarks in Safari and your other browsers on your Mac, and Safari's tabs on your other devices; read the page you have open; open pages in Safari, add them to your Reading List, open and switch tabs in Chrome, Arc, Edge and Brave, and close tabs after you approve it in your AI app. On your iPhone, add pages to Safari's Reading List, and block sites and trackers or hide parts of pages in Safari with Melvin's blocker.
• Read and set the clipboard on your Mac or iPhone. Passwords and codes it can recognize are hidden.
• See what is playing, play, pause and choose music, and add to your library on your Mac or iPhone, and on your Mac choose AirPlay speakers, control Spotify, and play and browse videos in the TV app.
• Show notifications, speak aloud and save speech as audio files on your Mac or iPhone, and read the notifications your apps showed on your Mac. Codes such as sign-in codes are hidden.
• Read and change what Melvin remembers about you on your Mac, and ask your iPhone what it remembers of your days: places, calendar, photos taken, music, Focus, alarms and AI tasks, kept on the iPhone. Health only when asked.
• Set, snooze and cancel alarms and timers on your iPhone.
• Read your Health data on your iPhone, add entries to it and put workouts on your Apple Watch. Your AI app asks you before removing entries.
• Read steps and activity from your iPhone, and its compass and other sensors.
• Know where your iPhone or Mac is, find places nearby, get travel times, directions and the weather on either, keep your saved places and remind you when to leave on your iPhone, and open places in Maps on your iPhone or Mac.
• Search your photos by date, place and text in them, organize and save photos, save copies from Photos on your Mac into your folders, and make shorter or smaller copies of videos. Your AI app asks you before deleting.
• Start calls from your iPhone or Mac, and fill in texts and emails on your iPhone. You press Send yourself, and your device asks before each call.
• See, read and change the files in Melvin's folder on your iPhone, and in the one folder you choose for your AI in Melvin's Settings. Your AI app asks you before deleting.
• Record, play and transcribe voice memos, take dictation, name songs and listen for sounds such as a doorbell on your iPhone; find, play and transcribe your Voice Memos recordings on your Mac, and record and transcribe meetings there from its microphone and the sound of your other apps, which macOS shows it is doing. A voice memo on your iPhone keeps recording or playing after you leave Melvin until it is stopped; dictation, naming songs and listening for sounds happen while Melvin is open.
• Open the camera on your iPhone for you to scan a document or a code, make QR codes and barcodes, and read or write NFC tags you hold to it.
• Read Wallet passes, offer them to Wallet for you to add, find and open books, and read your Apple Books highlights on your Mac.
• Turn the flashlight on or off and set the screen brightness on your iPhone, show progress on its Lock Screen, and pin a note to Melvin's widget.
• See the balances and transactions of your Apple Card, Apple Cash and Apple Savings on your iPhone, and add up your spending. Account numbers are never shown.
• Block and unblock groups of apps and websites for as long as you say: on your Mac, groups your AI makes, where Melvin quits those apps and closes those websites' tabs while it runs; on your iPhone, the groups you set up in Melvin.
• Translate text and tell what language it is in, with Apple's own translation on your iPhone or Mac.
• See and control your home's accessories and scenes. Your AI app asks you before unlocking, opening or disarming.
• Run the reading tools you choose on your devices at a time you set, such as your agenda every morning, and show what they found as a notification. No AI runs then.
• See and update the goals you keep in Melvin, and the ideas Melvin suggested.
• Read and use apps on your Mac: see their windows, press buttons, type and choose menu commands, and see your Mac's screen, save pictures of it and record it once you allow Melvin to record the screen in macOS. Your AI app asks you before it presses, types or chooses anything.
• Search the web, read web addresses, send requests to them and download files into your Downloads folder. On Melvin Agent, also use websites for you in Melvin's cloud browser, signed in where you saved a login; your AI app asks you before each task or step on a website.
• Run Terminal commands, AppleScript and Melvin's ready-made scripts on your Mac, and replace text files, the old version kept in the Trash. Melvin never runs one that asks for admin rights, reads saved passwords, sign-ins or private keys, or turns off macOS's protections.
• Change your Mac's volume, speaker, microphone, brightness, appearance, Wi-Fi, Bluetooth and VPN connections and wallpaper, join Wi-Fi networks on your Mac or iPhone, keep it awake, sleep its display, lock its screen, see what Mac it is, its updates, apps, battery, drives, printer list and print jobs, scanners, backups and how busy it is, start a backup, print, scan paper into a PDF, eject drives, open pages in your browser, and tell you on your Mac when something happens. Your AI app asks you before restarting, shutting down or sleeping it, cancelling a print job or emptying the Trash.
• Run actions your apps offer to Shortcuts, for the apps you add in Melvin on your Mac or iPhone. Your AI app asks you before each action runs.
• Set up automations on your Mac that act on new files or on a schedule, after you approve each one on your Mac. Sending or deleting still asks you each time.
• See and cancel the iMessages and emails this app scheduled to be sent later from your Mac. Each goes only if your Mac is awake with Melvin open at its time, and Melvin tells you if it could not.
• Your AI app asks you before Melvin deletes anything.
• Melvin can use only what macOS and iOS let it, which you choose when you set it up.
• You can disconnect it any time, on your Devices page or from the Melvin menu on your Mac.

The full guide, with approvals and how to take access back, is on the connector help page.

Your AI talks to Melvin, never to your Mac. Your Mac keeps its own connection out to Melvin, so nothing on it is opened to the internet: no ports, no router settings.

Your Mac has to be awake with Melvin open for a task to run. If it is asleep, the chat says so straight away instead of saving the task to run later without you.

To take it all back, choose Disconnect all AI apps in the Melvin menu on your Mac, or on your Devices page. Every app stops working at once.

For power users, and for apps that cannot use the steps above. Melvin is a remote MCP server at https://trymelvin.com/mcp that signs you in with OAuth, and it supports dynamic client registration, so no client ID or secret is needed.
