Manus vs Simular Sai

Manus

• Handing off multi-step research and getting a finished report back
• Producing slide decks, websites and simple web apps from a prompt
• Teams that want pooled credits and usage analytics

Simular Sai

• Recurring tasks in desktop software or portals that offer no API
• People who want automation that keeps running with their laptop closed
• Developers adding computer use to a coding agent through MCP

Manus

• Usage is metered in credits, and unused monthly credits do not roll over to the next cycle.
• Free accounts are limited to the Manus 2.0 Lite model in Agent Mode, 1 concurrent task and 1,500 daily-refresh credits a month.
• The pricing page lists Pro tiers of 4,000, 8,000 and 40,000 credits a month; the help center states prices only for the first two.
• The macOS desktop download is labeled for Apple Silicon, and no Linux app is listed.

Simular Sai

• The free Explore plan has a daily credit allowance whose size the pricing page does not state, and only limited access to a cloud computer.
• On Pay as you go, the $50 a month of credits pays for both AI usage and cloud computer time; heavier use needs top-ups.
• Sai Unlimited costs $500 a month and covers one workspace; additional workspaces are upgraded separately.
• Running Sai on your own device is offered for Mac and Windows, while the cloud computers are Windows or Linux.

Manus

Agent Mode

Tasks run in a cloud virtual machine that handles file operations, browser automation and code execution. Credits are consumed only while a task is actively processing.

Wide Research

Splits a large research job across many agents working in parallel and returns reports and datasets. The pricing page lists it among the paid Pro features.

Slides, websites and web apps

Generates slide decks from a prompt and builds full-stack web apps with a built-in database, backend and login, which can be deployed and connected to a custom domain.

Browser Operator

A Chrome extension that lets Manus work inside your own browser session, using your existing logins and open tabs once you grant it access.

Scheduled and concurrent tasks

Tasks can run on a schedule and side by side: 2 scheduled tasks and 1 concurrent task on the free plan, 20 of each on Pro.

Connectors and API

Connects to apps such as Gmail, Notion, Slack, Google Calendar and GitHub. A public API can create tasks, send follow-up messages and retrieve results.

Simular Sai

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.
