# Get Hjarni on every device

Hjarni is a knowledge base with a built-in MCP server. Use it in any browser, in the free apps for iPhone, iPad, Mac and Android, and inside Claude and ChatGPT. One account, one set of notes, everywhere.

## On your phone and your Mac

The apps are free, with the same features as the web. Write a note in a queue, and the next time Claude or ChatGPT searches your notes, it is there.

### iPhone and iPad

Capture a note, attach a photo from the camera, and search everything you have saved.

Free on the App Store. Needs iOS 16 or later.

### Android

The same five tabs and the same notes as on iPhone. Photos and files attach from your phone too.

Free on Google Play. Needs Android 9 or later.

### Mac

The iPhone and iPad app runs as a proper Mac window: the sidebar stays open, and Cmd-N starts a new note.

Needs an Apple Silicon Mac. In the Mac App Store, look under iPhone & iPad Apps.

## In any browser

### The web app

Everything works at hjarni.com, on any operating system. Nothing to install.

### Chrome web clipper

Click the toolbar icon on any article. It opens a clean Markdown copy with the source link, ready to save to your Hjarni inbox.

Free in the Chrome Web Store.

## Inside the assistant you already use

Hjarni is listed in both the Claude and ChatGPT directories, so connecting is an install, not a config file.

### Claude

Open the listing, press Connect and sign in. Then click + in a conversation and switch Hjarni on under Connectors.

Works in Claude.ai, Claude Desktop and Claude on iOS.
