What Is Manus AI? How to Use It, Pricing, and an Honest Review (2026)

Manus went viral in 2025 in an unusual way. Invite codes were selling for thousands of dollars. What people were chasing was its agent capability: give it one sentence, and it handles the rest. Not just a chat assistant. Something that actually does things.

Two years on, it’s open to most users for free. The conversation around it has also gotten more complicated: company relocation, a Meta acquisition that China then ordered unwound, data privacy questions. This article tries to lay out what it can and can’t do, plus the company background, and let you decide if it fits.

What Manus Is

Manus (manus.im) is an autonomous AI agent built by Butterfly Effect Pte. Ltd. The key difference from a regular AI chat tool is execution: give Manus a task and it breaks it into steps, then goes and browses pages, runs code, manages files, and produces a finished output. That might be a research report, a presentation, organized data, or a website prototype. You don’t need to guide it one prompt at a time.

You can watch the whole process live in the right-side panel: which page it’s checking, what terminal commands it’s running, which step it’s on. That transparency is one of the things Manus specifically designed for.

Manus doesn’t train its own base language model. It relies on third-party models. Based on public reporting, it primarily uses the Claude family as its reasoning backbone, which means a Claude outage affects Manus availability too.

Company Background and the Controversy

A few facts worth knowing, taken together.

Origins and relocation. The Manus development team was founded in China (Beijing and Wuhan) in 2022. By mid-2025, the company moved its legal entity to Singapore, shut down its mainland team, and closed its Chinese social accounts.

The Meta acquisition. Meta completed its acquisition of Manus in December 2025, reportedly for around US$2 billion. On April 27, 2026, China’s National Development and Reform Commission (NDRC) issued an order requiring the completed deal to be unwound, citing national security. The NDRC’s position: Singapore registration doesn’t place the company outside Beijing’s jurisdiction. This was the first time China used foreign investment security review to unwind a completed cross-border AI transaction. As of June 2026, the unwind order is in effect, Meta is dismantling the integration (some reporting suggests it may shut down the platform), the two co-founders are under Beijing exit restrictions, and three founders are reportedly trying to raise around $1 billion to buy the company back. The product at manus.im still works, but the company is in a forced dissolution transition, and where things land is not settled.

Data privacy. Manus is legally in Singapore, but the team’s background and early operations have extensive China connections. Server location and data flows don’t have a complete public accounting. If your use case involves sensitive business data or personal information, that context is worth a minute of thought before you start. No evidence says there’s a problem. The public information also isn’t sufficient to rule one out. That’s the honest position.

These are verifiable facts. People weigh them differently. This article doesn’t draw the conclusion for you.

How to Get Started

1. Go to manus.im
2. Sign in with email, Google, Apple, or Microsoft
3. After account setup you’ll receive starting credits (roughly 1,000-1,500)
4. Select Agent Mode (not Chat Mode: Chat Mode is free but doesn’t execute tasks)
5. Attach any relevant files as background context
6. Write your task prompt: include context, goal, expected output format, and a numbered list of requirements
7. Click Run and watch execution in the right panel
8. Download the output when done; keep an eye on the credit balance in the top right corner throughout

Write specific prompts. Vague instructions make the agent spend more steps figuring out what you want, and every step burns credits. “Research the Taiwan electric vehicle market and produce a PDF report in Traditional Chinese with market share, major brands, and consumer trends, with source citations on the last page” is not just better quality than “research the EV market.” It’s cheaper and takes fewer retries.

The “My Computer” feature released in March 2026 lets Manus access local files and the terminal. It asks for permission command by command; it doesn’t operate silently in the background.

Pricing and Credits

Plan details and credit numbers: check manus.im directly, as these change frequently.

The important credit warning:

Chat Mode is free. Agent Mode costs credits. Credit consumption varies a lot: simple queries run 10-50, deep research tasks 500-900.

Here’s the trap: independent reviews consistently show actual consumption running well above Manus’s own estimates, in some cases 2-4 times higher. A complex open-ended task can burn through an entire month’s allowance in a single run.

A few mechanics to know:

• Free plan daily credits don’t carry over. What you don’t use today is gone.
• Monthly quotas don’t roll over. They reset at month end. (Separately purchased credits are an exception and stay valid through your paid period.)
• If credits run out mid-task, the agent stops where it is. You get an incomplete output, with no graceful recovery.

The practical move: before running a new type of task at full scale, run a smaller version first to see how fast it burns, then decide whether to go bigger.

What It’s Good at and Where It Falls Short

Where Manus works well:

• Open-ended multi-source research. Researching a market, building a competitive analysis, pulling together information from many sources. This is where Manus is strongest.
• Travel and itinerary planning. Give it a destination, number of days, and budget. It can check flights, attractions, and accommodation and assemble something usable.
• Long tasks you can walk away from. Fifteen to ninety minutes of background execution without babysitting.
• Watching AI work. If you want to see an AI step through a process in real time, Manus has the most transparent interface for it.

Real limitations (from independent reviews):

• Paywalls and CAPTCHAs stop it cold. Sites requiring login or verification checks trip it up constantly.
• Stability is inconsistent. Crashes, high-load errors, and mid-task stops are reported by many users, not a handful.
• Coding on a real codebase is weaker than Cursor or Claude Code. Editing existing projects or debugging is not where Manus shines.
• Credits running out mid-task means an unfinished result. There’s no graceful pause-and-resume.
• No team collaboration features on basic plans.

Short version: Manus has real value for its best scenarios (long tasks, open-ended research, data aggregation). It’s not a universal agent. Framing it as “research assistant” rather than “does everything” sets more accurate expectations.

Traditional Chinese and Taiwan Access

Traditional Chinese. The underlying Claude-family models should handle Traditional Chinese input at a reasonable level. Manus hasn’t officially listed Traditional Chinese as a tested or supported language, and the interface is primarily in English. Personal testing is the only reliable gauge. Specifying “Traditional Chinese” output in your prompt usually helps.

Taiwan access. Taiwan works. Manus runs a Traditional Chinese (zh-tw) page and is actively marketing to Taiwanese users. The only confirmed geo-block is mainland China IP addresses. Claims circulating online about Taiwan being restricted don’t trace back to a reliable source; the likely explanation is confusion with restrictions on other China-origin AI products.

The data privacy reality. Manus operates under Singapore law, but as covered in the background section, transparency on server locations and data flows is limited. If your task involves sensitive business information, personal data, or anything that needs to stay confidential, spend a moment evaluating that before you proceed. Treat it as standard due diligence before picking any tool.

How It Compares to Other Agents

ChatGPT Agent is better value for most users: it comes with Plus at $20/month, and short tasks don’t drain it. Manus’s differentiation is specifically in long open-ended research tasks. Claude itself is stronger than Manus for document analysis, long-form writing, coding, and API use, but doesn’t have Manus’s autonomous multi-step execution (Claude Code is a different category, not the same type of product).

OpenAI Deep Research is the closest competitor to Manus on research use cases. Both aggregate from multiple sources. The difference: Deep Research output skews more academic, Manus is more dynamic in execution.

Conclusion

The problem Manus solves is real. Many tasks actually need execution power, not just smart answers. A tool that can run fifteen steps on its own has value. Manus does that part.

But a few things are worth evaluating before upgrading.

Credit burn needs a calibration period. Budget 2-4x your expected spend and you’re less likely to be surprised. The Free plan’s 300 daily credits is fine for trying one or two tasks. As an actual work tool, you need to do the math.

Stability is a genuine problem. Paying for a task that stops halfway through is frustrating. Multiple independent reviewers have flagged this. It’s not an edge case.

The company background is a fact, not a verdict. Singapore HQ, Meta acquisition being unwound by Beijing, limited data transparency: these are checkable. How much weight they carry depends on what you’re using Manus for. Dropping in personal entertainment tasks is a different conversation from putting confidential company data through it.

Manus is a good fit if you want to hand off long multi-source research, you’re willing to learn the credit system, and your tasks don’t involve highly sensitive data. Less of a fit if your main need is coding, you have low tolerance for tool instability, or you need to process anything sensitive.
