Backed by computer using agent: Sai can open your macOS apps, clicks, types and reads the screen until the work is done.
Finder, Mail, Numbers, Safari and third-party Mac apps, through the same interface you use. Including the ones that never had an API.
Every step is readable, and Sai stops for your sign-off before deleting, sending or paying.
Runs without your machine.

Three things that make it usable on real work
Sai works the full macOS desktop the way a person does — handling interfaces, applications and multi-step workflows directly, instead of stopping at chat or at whatever a narrow integration exposes.
Sai checks with you before critical actions, keeps every step readable, and lets you edit or stop a run. Useful without feeling risky.
Sai scores 73.0%, ahead of Claude Opus 5 Max Thinking at 70.6% and GPT-5.6 Sol Max at 62.6% — at $15.70 per task against $23.70 and $26.62. On the stricter binary success rate: 28.25%, vs 23.14% and 13.10%
Sai works with the Mac apps and sites you already use, with no integration work. Say what needs to happen, not how to click through it.
Keep it local on Apple Silicon, or hand it to an isolated remote machine so your own setup stays untouched.
Clicking, typing, navigating — this is what a computer use agent does. Every step is readable, and critical ones wait for your approval.
Save the run as a workflow and it repeats without you — nightly, weekly, or on a trigger.
Choose the plan that fits your needs
Your autonomous computer is ready in minutes — no setup, no integrations.
