The products are different on purpose, but the product standard stays the same.
Core work should happen close to the device when a server is not necessary.
The app should not manufacture reasons to keep you inside it.
Outputs should be readable, shareable, and easy to explain.
A focused tool should have the courage to leave things out.
Clairos makes focused apps for everyday calculations, private writing, spatial whiteboarding, real estate math, weather, and hands-on technical learning.
Local-first is the default design direction. Core work should stay on the device when possible, with network features used only when they clearly serve the task.
Some Clairos apps are free, some may include optional purchases, and some products may have professional versions. Each product page or store listing is the source of truth for current pricing.
Because all-in-one tools often create more interface drag than they remove. Clairos favors smaller tools with clearer jobs.
