What it is and who it's for
Manus is an autonomous general-purpose AI agent: you give it a goal, it breaks it into steps on its own and executes them in its own cloud environment — searching the web, writing and running code, working with files, assembling reports, sites and spreadsheets, and carrying the task to a result with minimal intervention. It's for analysts, product people and founders who want a "delegate and forget" executor for complex multi-step work. What stands out is that it beat OpenAI Deep Research on the GAIA benchmark (real multi-step assignments), and that it's backed by Benchmark.
Key features
- Autonomous planning and execution of multi-step tasks in a cloud environment.
- Web browsing, code execution and file/data handling under the hood.
- Builds artifacts: reports, presentations, simple websites, spreadsheets, dashboards.
- Async by design: you set the task, the agent works in the background.
- You can watch the agent's steps (transparency into its process).
- Web access; modes for different classes of tasks.
Get started in 5 minutes
- Go to manus.im and sign in (access and credits depend on your plan).
- Set a concrete goal with success criteria (what counts as "done").
- Let the agent work, watch the steps and correct course; collect the finished artifact.
When to use it, when not to
- ✅ Use it if you want to hand off a complex multi-step task (research + producing the deliverable) end to end.
- ✅ Use it if async matters — you kick it off and get on with your day while the agent works.
- ❌ Skip it → Claude Code or OpenHands is better if the task is development in your own repo, under your supervision.
- ❌ Skip it → Perplexity is better if you want a fast sourced answer rather than a long autonomous pipeline.
Honest pricing
Access is by subscription/credits; long, complex tasks consume more. There's limited free access. Exact numbers are on the provider's site and keep changing.
Gotchas
- Autonomous doesn't mean error-free: over long chains the agent can wander off — it needs a clear goal and supervision.
- Credits burn fast on heavy tasks.
- The agent acts on the web on your behalf — hand over credentials and data deliberately.
- Check the output (facts, code, conclusions) before you use it.
🤖 Prompt accelerator
"I want to delegate a task to Manus: <DESCRIBE — e.g. competitive analysis + dashboard / landing page / report>. Help me phrase the goal so the agent can work autonomously: define the "done" criteria, the sources/data it needs, the output format and the constraints. Break the task into verifiable stages and tell me what to check in the result (facts, code, correctness) before using it."
