Sentient OS launches on-device AI that reads user data at night

On October 28, 2026, Sentient OS released on-device AI that at night uses a local LLM to read the user's messages, files, and notes, and writes what it learns into a pure markdown folder on the computer, which the user can open, edit, or delete. On the same day, Testing Catalog reported that Sentient released the open-source AI model Sentient OS, which can gather context from local files and messages and execute tasks on the user's computer; its Sidekick feature supports handing off tasks such as forms or emails open on the screen for it to complete using its own cursor. The report also said that what it learns is stored locally as plain text files, which users can open and edit; the first 1,000 users who enter FINAL_1000 in the app can use it free for life. Another report from the same day mentioned that during the day, Double Tap and Sidekick read these files to draft replies and complete tasks in apps, and only heavier tasks call the user-selected cloud model. There have been no further developments so far.
