AISummary of 3 articles

Sentient has launched Sentient OS, an open-source AI agent that uses context from local files and messages to carry out tasks on a user's computer, according to Testing Catalog.

Its Sidekick feature lets users hand off an open form or email for Sentient to finish with its own cursor, and users can view and edit what it learns, stored locally as plain text files.

Rohan Paul (@rohanpaul_ai) says the app reads messages, files and notes overnight with a local LLM and writes what it learns into markdown files. Santiago (@svpino) says it also draws on emails and calendar events and runs a local Gemma 4 E4B model through LiteRT-LM. Santiago names the app as Sentient OS, launched by Aditya Vellanki.

Testing Catalog says the first 1,000 users who enter the code FINAL_1000 in the app keep it free for life. The reports do not state the price for other users.

    Sentient OS launches on-device AI that reads messages and files overnight

    AISentient OS has launched an on-device AI that reads users' messages, files and notes overnight using a local LLM. Each night it writes what it learns into a folder of plain markdown files that users can open, edit or delete. During the day, Double Tap and Sidekick read those files to draft replies and finish tasks, calling a cloud model the user chooses only for heavier work.
