An AI companion that lives on your computer.

It remembers between sessions. With a local model, nothing leaves the PC.

You can see and hear her: 3D and pet modes, Whisper speech to text, a voice on the device or in the cloud, and replies in the chat apps you already use.

Coming

Your team of bots.

Coming: a team of TerranSoul bots in one room. Each bot has its own character, brain, memory and voice. You mention one with @, it answers, and it asks before it acts.

Bot teams are in development. Today you get one companion, one memory shared with your coding tools, and your choice of model.

Questions

Do I need an account?

No. TerranSoul works without one. An account lets you reach your PC from a browser.

Is the account free?

Yes. Sign-up is free through Terranimus Identity.

Which systems does it run on?

Windows, macOS and Linux. Browser access to an agent needs the PC to be online.

Can I run several bots?

Not yet. Bot teams are in development; today there is one companion, and your coding tools share its memory.

Why does Windows show a SmartScreen warning?

New installers have no download history yet. The download page on terranimus.com lists each file's SHA-256 so you can check it.

Who can control my TerranSoul?

Only browsers that you approved on the PC itself. The site never sees or moves your screen.

Where do my memories live?

In a database on your PC. The site does not store them.
