SAI FOR AGENT BUILDERS

Autonomous computer service for building always-on agents that fit your needs.

Meet Sai. An autonomous computer, not just an API call. Give your agent computer-use capabilities and instant cloud machines, run by the top-benchmarked agent on OSWorld — without building computer-use infrastructure from scratch.

INTERACTIVE PLAYGROUND

Four tools your agent can call this week.

Every tool is a plain-language task plus the shape of the result you want back. Call it from your agent, check the output once, then save it as a replayable skill.

Per request · tool call

Check invoice status in a supplier portal with no API

Prompt

You are being called as a tool by another agent. Check the 14 invoice numbers in the attached list in the Acme Supplies supplier portal, which has no API. For each, record status (Paid, Pending, Disputed), amount, due date and any supplier note. If one is Disputed, download the dispute PDF to Drive > Procurement > Disputes. Read only: do not submit, approve, dispute or pay anything. Ask before signing in, say so if an invoice is not found, and stop after 15 minutes. Return one row per invoice, then totals by status.

WHY SAI FOR AGENT BUILDERS

Computer use for your agent. Simple to add, token-efficient to run.

One tool call. No computer-use stack to build.

Raw computer use means a sandboxed VM, a screenshot loop, an action handler and the scaling around them. Sai ships all of it as one API: managed Windows and Linux cloud computers, or your customer's own Mac or Windows machine, with the top-benchmarked computer-use agent already on board.

Typed results your agent can act on.

Send a JSON Schema with the task and the turn returns output that matches it, plus a record of each step. Your agent reads the fields directly instead of parsing a paragraph. Check a run yourself or with the judge endpoint before your agent acts on it.

Built for run #100, not run #1.

An agent that re-plans every click on every call gets slow and expensive at volume. Sai turns a finished task into learned code and replays it, asking the model only where the screen matters, so repeat calls use up to 90% fewer tokens. When a portal changes its layout, the agent takes over and repairs the code.

Ship it to your customers, safely.

Run Sai for your own customers with an Organisation: each customer is a Tenant whose machines, files and sessions are kept apart, and your Organisation pays for all of them. Sign-ins and credentials go to the right person as an approval link, so a password never passes through your agent.

Plugs into your agent framework — and the systems it can't reach.

Add Sai as one tool in the framework you already ship. Where a system has an API, your agent keeps calling it. Where it doesn't, Sai works the screen.
