Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 12 of the 51 other AI agents we grade
Sai is a computer-use agent from Simular that completes tasks by seeing the screen and clicking and typing through browsers, desktop apps, file systems and terminals, so it can work in software that has no API. It runs on a dedicated cloud computer that keeps your logins and setup between sessions, or on your own Mac or Windows machine, and a task taught once can be rerun on a schedule. A free plan has a daily credit allowance; paid plans start at $50 a month of usage credits.
To get you started, here are 9 things to know about Simular Sai, taken from its own pages and our grades.
No rating on record, and you don't just switch this on.
- 1
Best for repeat tasks in software that has no API
Sai is an agent that uses a computer the way you do, looking at the screen and clicking and typing, so it can work in an old portal or desktop program with no API and rerun a taught task on a schedule.
- 2
Paid plans start at $50 a month
As its pricing page puts it: $50 per month (Pay as you go, includes 50,000 credits).
- 3
There is a free plan
Explore plan: a credit allowance refreshed daily, limited access to a cloud-based Windows computer, workflow creation and testing, and community support.
- 4
It runs on 3 platforms
Web, macOS and Windows.
- 5
Operates real interfaces
Sai sees the screen and clicks and types through browsers, desktop apps, file systems and terminals, so it can handle software that offers no API.
- 6
Dedicated cloud computer
Sai works in its own Windows or Linux cloud machine, which keeps your logins, preferences and context between sessions and carries on after you close your laptop.
- 7
Bring your own device
Sai can run on your own Mac, Mac mini or Windows machine instead. On Pay as you go, only AI usage is then charged, with no computer time.
- 8
A 2.2 GPA, above 12 of 51
That is against the other AI agents we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace Simular Sai you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for repeat tasks in software that has no API
Sai is an agent that uses a computer the way you do, looking at the screen and clicking and typing, so it can work in an old portal or desktop program with no API and rerun a taught task on a schedule. Paid plans start at $50 a month, and those credits cover both the AI and the cloud computer's time, so real use means top-ups. The free plan's daily allowance isn't stated, and an always-on machine is $500 a month for one workspace.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | Pay as you go starts at $50 a month, which is exactly where the dearest tenth of agent tools here begins, against a $21.25 middle. That $50 of credits has to cover both the AI and the cloud computer's running time, so real use means top-ups. An always-on machine is $500 a month, for one workspace. |
| Free plan and trial | C | Explore costs nothing, no card, and the credits refresh daily with room to create and test a workflow. But the pricing page never says how big that daily allowance is, and cloud computer access is only 'limited'. A cap you'll hit, and not one you can plan around. |
| Features | B | It covers the whole job, on real interfaces: browsers, desktop apps, file systems and terminals, so nothing needs an API. The cloud machine keeps your logins and runs with your laptop shut, taught tasks save as skills and rerun on a schedule, and there's an API and MCP server. Manus and airtop do the same, so no A. |
| Ease of use | C | No rating on record, and you don't just switch this on. You teach it the task, watch the run and approve the critical steps before you'd leave it alone with anything. It pings you by iMessage, SMS or Telegram when it's stuck. |
| Platforms and integrations | B | The browser plus your own Mac or Windows machine, with the cloud computers running Windows or Linux. No phone app is listed, though it messages you by iMessage, SMS or Telegram. An API and an MCP server let Claude Code, Codex and Cursor call it. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Simular Sai is for
- Fits if you have a weekly chore in desktop software or a portal that offers no API
- Works for developers adding computer use to a coding agent through MCP
Who it is not for
- Pricey if you'd only use it now and then, since paid plans start at $50 a month
- Tight if you're staying free, with a daily allowance of unstated size and limited cloud computer access
- Skip it if you need several workspaces on Unlimited, as $500 a month covers just one
- Watch out: the $50 of credits pays for both AI usage and cloud computer time, so heavier use needs top-ups
- Watch out: heavy use on Unlimited may shift Sai into an efficiency mode, and no phone app is listed
Good to know
Good for
- Recurring tasks in desktop software or portals that offer no API
- People who want automation that keeps running with their laptop closed

Worth knowing

Part 03 · Features
What it does
Its main features, where it runs, what it works with and who makes it
3
Places it runs: Web, macOS and Windows
Computer-use agent that operates a cloud desktop or your own computer. Here is what it does, as its own site describes it, and what it covers: public API, workflow automation, AI agents.
It covers the whole job, on real interfaces: browsers, desktop apps, file systems and terminals, so nothing needs an API.
- Operates real interfaces
- Sai sees the screen and clicks and types through browsers, desktop apps, file systems and terminals, so it can handle software that offers no API.
- Dedicated cloud computer
- Sai works in its own Windows or Linux cloud machine, which keeps your logins, preferences and context between sessions and carries on after you close your laptop.
- Bring your own device
- Sai can run on your own Mac, Mac mini or Windows machine instead. On Pay as you go, only AI usage is then charged, with no computer time.
- Scheduled reruns that reuse steps
- A task taught once can be saved as a reusable skill and rerun on a schedule. Simular says the unchanged steps become code, so repeat runs need fewer model tokens.
- Approvals and live view
- You can watch Sai's computers work, approve its critical steps, and get notified by iMessage, SMS or Telegram when a task needs you.
- API and MCP server
- The Simular Platform exposes Sai through an API key and an MCP server that coding agents such as Claude Code, Codex and Cursor can call.

12/51
Other AI agents it is graded above
Simular Sai's GPA of 2.2 is higher than 12 of the 51 other AI agents we grade, and level with 10.
It stands best on features (B, above 27 of 51) and worst on value for money (D, above 0).
Its paid plans start at $50 a month, against a middle price of $21.25 for the category: 40 of the 44 others that charge start lower.
On features, ease of use and platforms it scores 2.7 out of 4. 8 tools score higher and cost less.
Each grade against the category

Each dot is one of 49 AI agents. Further left costs less; higher up scores better on features, ease of use and platforms. Simular Sai is the marked dot.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Simular Sai you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 29 of the 51 other AI agents grade higher. It costs $600 a year.
What you could not
- An AI agent, with the models and the safeguards behind it.
- Connections to other products, each kept working as those products change.
- A real app for macOS and Windows. Something home-made would be a web page.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Simular Sai’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
