The AI assistant for Windows you can actually talk to
Callisto is a desktop AI assistant built for Windows 10 and 11. Speak to your PC and it answers out loud, opens what you need, and gets work done.
What it does on your PC
- Finds and opens files without you saying the file type: "open my invoice".
- Opens apps, folders and websites by voice.
- Screen assist looks at what you are working on and walks you through it step by step, and can help fix code while you work.
- A system-wide shortcut brings it up from any app.
- Hand gestures can move an on-screen cursor if you want to work hands-free.
Why a desktop app rather than a browser tab
- It can reach your files and apps, which a website cannot.
- Video editing runs on your own computer, so the file is not uploaded.
- It updates itself and sits in your tray, ready when you speak.
More than answers
- Make pictures, posters, videos and 3D models.
- Write Word documents, PowerPoint slides, PDFs and Excel spreadsheets.
- See your Instagram, TikTok, YouTube, Stripe and website numbers in one place.
Free to download for Windows and Mac. The free plan includes 15 messages a day and 2 images, 2 videos and 2 3D models a week. Premium is $20 a month.
