Sai is the world's first robosecretary that works with a fleet of autonomous computers, doing your endless screen work. Each computer navigates software the way you do: reads the screen, clicks the button, types in the form. Trained to interact with the computer interface, Sai automates software even when they lack APIs: legacy desktop apps, internal portals, anything behind a login. Sai supports Windows, macOS and Linux. 73% on OSWorld.
Sai is the world's first robosecretary that comes together with a fleet of autonomous computers doing your endless screen work. We believe the future of work isn't just one computer — it's many computer.
Each computer navigates software the way you do: reads the screen, clicks the button, types in the form. That's the whole point. Because Sai works at the interface layer, it automates things that have no API and never will — legacy desktop apps, internal portals, anything behind a login. Windows, macOS, and Linux. 73% on OSWorld.
What that buys you in practice:
🖥️ Real computers, not a chat box. You hand over a task, it runs it on an actual desktop. Open the workspace any time to watch, or take the mouse back mid-run.
🔁 It learns the route once. Any finished task can be saved as a skill, scheduled, or triggered by an event — so the tenth run is faster and cheaper than the first.
🔒 Autonomy with a seatbelt. Tiered approvals, "trust for this task," and encrypted input for passwords and codes — the model never sees plaintext.
The agent we actually optimize for is whether it's still useful and affordable the tenth time you ask.
Tell us the screen work that eats your week — we'll tell you honestly whether Sai can take it off your hands.

Who hunted Sai?
Sai was hunted by Justin Jincaid. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
