Sentient OS Launches Local AI to Process Digital Life Overnight
YC-backed Sentient OS has launched an on-device AI system that uses local LLMs to scan user messages, files, and notes overnight.

Local models have reached the point where it makes sense to let one read your entire digital life every night.
Sentient OS just launched an on-device AI that reads your messages, files and notes overnight with a local LLM.
Each night it writes what it learns into a folder of plain markdown files on your computer, which you can open, edit or delete. During the day, Double Tap and Sidekick read from those files to draft your replies and finish tasks in your apps, calling a cloud model you choose only for the heavier work.
