Latis is an early prototype. We're looking for a few people to try it and tell us what's missing.
Latis began as Atlas OS, a local-first personal operating system that Yajat started building on his own Mac. The idea was simple: one place for notes, plans, money and health, with an assistant that never needed your data to leave the computer.
As it grew, so did the ambition. Shiven joined as co-founder to take it beyond one desk, and in October 2026 Atlas was renamed Latis, with a new logo. The assistant kept its name: Nova.
We're deliberately getting a solid local prototype right before anything else. Testers come next.
Yajat leads the technical build, from notes and calendar to Nova, the assistant that runs on your own Mac. He placed 1st in Part A of the National Cipher Challenge and 64th of 5,453 teams in Part B, competing on his own. He has also built a physics simulator with a neural network that predicts how objects move.
Shiven handles the business side: finding our first testers, speaking to the people we want to learn from, and getting the company ready. He co-founded NovaSoc, an astrophysics society with chapters in the UK, Europe and India that launched a free international competition. He also built DailyEngineering, a daily question site that has reached over a million users in more than 190 countries.
Every stage starts as a written plan with its open questions answered before any code changes.
Automated tests aren't enough. Each stage passes a hands-on acceptance checklist on a real Mac before it's called done.
Shiven talks to the people we want to learn from, so what gets built next comes from what testers actually need.
We're keeping the first group small so every piece of feedback gets read and acted on.
We're looking for a handful of Mac users to try Latis and tell us honestly what's missing.
