This one has been a long time coming.

The last version of TheBrain to run on Linux was Version 8, more than a decade ago. Bringing it back has been one of our most requested features ever since, and something we've wanted to deliver on for just as long. Today, with TheBrain 15 for Linux now in beta, it's finally here.

What's in the box

This isn't a stripped-down port. It's the same TheBrain 15 our Windows and macOS users have been enjoying, with everything you'd expect:

• The animated visual plex
• Cerebro AI
• Rich Markdown editor
• On-demand sync and full offline capabilities
• Import and export
• The local API

On top of that, the Linux build picks up the native niceties that make a desktop app feel at home on the platform: drag and drop, the embedded browser, drag-to-float tabs, and fully-indexed local search.

In our own testing this is by far the best version of TheBrain on Linux that has ever existed — on par with the Windows and macOS builds, and in some workflows arguably faster.

If you've been waiting

If you're a Linux user who has felt left out of TheBrain over the years — this is the moment you've been waiting for. Grab it, point it at your brain, and dive in. We've also opened a dedicated Linux category on the forums where the conversation is already underway — come join in.

We're grateful to everyone who kept asking, nudging, and patiently waiting for support over the years. You're the reason this happened.

It's good to be back.
