A private operating system for your life, as a Mac app. Notes, projects, tasks, calendar, money and health live together in one place, with an AI assistant, Nova, that runs on your own computer.
Mac users who want their plans and records in one app, and who'd rather not hand their whole life to a cloud service to get an assistant that can help with it.
Yes, it's free to start. Nova runs on a free AI model on your own computer, so there's no subscription for the assistant and no charge per question.
Not yet. It's an early prototype for macOS. We're looking for a handful of Mac users to try it and tell us honestly what's missing.
Right now, by joining early testing. Join the waitlist and we'll send you a build and the user guide.
No. Your notes, tasks, calendar, money and health data are stored in a database on your Mac, and Nova runs there too. There's no Latis server holding a copy.
No cloud account. You set Latis up on your Mac and that's it.
No. Voice is push to talk: the microphone is on only while you hold the talk key. We decided against any mode that listens in the background.
Every item you've marked private. They disappear from the screen, and Latis also stops reading them, so Nova can't mention them in an answer while you're sharing your screen.
Not yet, and we'll keep saying so until it has. The privacy page explains exactly how your data is handled today.
Find things across your notes, tasks and calendar, answer questions about them, create notes, add tasks and plan meetings. It can delete things too, but only after you approve.
A free, open model run through Ollama on your Mac. The current default is Qwen3 4B Instruct, chosen because it answers directly and runs well on an 8 GB Mac.
Nova's answers are worked out on your Mac, not on a server. You'll need a connection to download Latis and the AI model when you set it up.
Every answer lists the notes, tasks and events it was based on, so you can check it. When Nova can't find something it says so, and if it claims something is missing when the search found it, Latis flags it.
No. It shows you the exact item and waits. With voice, a spoken approval will need a clear yes plus the item's name.
It's being built and tested now. The first version is push to talk, fully offline and free, and does everything typing can.
No. Latis is built and tested on an M2 Mac with 8 GB of memory. If you're on a different Mac, tell us how it runs.
Not yet. Latis is macOS only for now. More devices are on the roadmap, after the Mac app is solid.
[YOUR DOWNLOAD SIZE] for the app, plus the AI model, which Ollama downloads once.
Voice first, then a new look, a better Calendar with Day, Week, Month and Year views, and a full Home screen. The roadmap has the full list.
Please do. Early testers shape what gets built next. Join the waitlist and tell us what you'd use.
