I Tested Manus AI: Complete Review of This Game-Changing Tool

Imagine stumbling upon a tool that feels like a glimpse into the future—a digital companion that doesn't just follow instructions but takes charge, turning your ideas into reality with minimal effort. That's the thrill I felt when I got my hands on Manus AI, a cutting-edge, fully autonomous AI agent that's creating waves in the tech world. With just three tasks to test its capabilities, I dove in, eager to see what this tool could do. Spoiler alert: it's as exciting as it sounds, with a few quirks that make the journey even more human. Here's a detailed manus ai review guide to my experience with Manus AI, from planning a dream trip to redesigning a website and even building an app—all with a spark of curiosity and a lot of heart.

What Makes Manus AI Special?

Manus AI, developed by Monica and accessible via manus.im, isn't your typical chatbot. It's an autonomous AI agent—a term that perfectly captures its ability to independently plan and execute complex tasks. Unlike traditional AI that needs constant nudging, this AI agent takes a single prompt and runs with it, browsing the web, writing code, and delivering polished results. It's like having a super-smart friend who gets things done while you're still sipping your morning coffee.

What sets it apart? Its full autonomy. You give it a goal, and it figures out the steps, from researching to creating deliverables like PDFs or HTML files. It's currently in an invite-only beta phase, which adds a layer of exclusivity, but don't worry—I'll walk you through how to get access and what I discovered in this manus ai review.

"Manus AI isn't just a tool; it's like a partner that brings your ideas to life with a mind of its own."

Getting Access: The Beta Journey

Securing access to Manus AI is like getting a golden ticket. Here's how I did it, and how you can too:

• Visit the Official Site: Head to manus.im and click "Get Started," then "Apply for Access."

• Sign In: Use a Google or Apple account (other email providers may not be supported yet).

• Submit a Detailed Application: Share your name, profession, and a compelling reason for wanting access. I wrote a lengthy explanation about testing this AI automation tool for creative projects, and it took about seven days to get my invitation code.

• Pro Tip: Be specific in your application. Mention real use cases like travel planning or coding to boost your chances. If you're stuck, tools like ChatGPT can help craft a persuasive pitch.

• Wait and Activate: Check your email for the invitation code, then use it to set up your account on manus.im.

The beta comes with three task credits, and trust me, you'll want to use them wisely. There's also an open-source version, OpenManus, for coders who want to tinker, though it's less feature-rich than the beta version of this autonomous AI agent.

Task 1: Planning a Dream Trip to Japan

For my first task, I wanted something fun and personal: a 10-day trip to Japan in May 2025 for me and my 13-year-old son, who's obsessed with gaming, animals, and food (especially sushi and ramen). I also threw in a challenge—could this AI agent check if I could use American Express or Chase credit card points for first-class flights from Newark (EWR) or JFK? If not, a detailed itinerary would do. Here's what happened:

The Prompt

I kept it straightforward: "Plan a 10-day trip for me and my 13-year-old son to Japan in May. He loves gaming, activities, animals, and food like sushi and ramen. Include three meals a day, break it down by morning, afternoon, and night, and check if I can use American Express or Chase points for first-class flights from EWR or JFK. If that's too complex, a full itinerary is fine."

The Process

The autonomous AI agent sprang into action, and watching it work was like seeing a detective solve a case. On the right-hand side of the interface, a dynamic panel flipped between browser, terminal, and VS Code views. It scoured Instagram, YouTube, American Express, and Japanese tourism sites, pulling data on gaming spots like Super Nintendo World, animal attractions, and ramen joints. It even researched credit card points but hit a snag—likely due to authentication barriers.

A "high load" error popped up, but Manus refunded my task credit and suggested I simplify the prompt. I removed the credit card part and reran it: "Create a full 10-day itinerary for Japan, focusing on gaming, animals, and food." This time, it delivered.

The Result

This AI automation tool produced a detailed itinerary, exported as a downloadable PDF, complete with:

• Trip Overview: Arrival in Tokyo, accommodation suggestions, and travel tips (like comfortable shoes and a Google Translate app for May's weather).

• Daily Breakdown: Each day was split into morning, afternoon, and night, with activities like visiting Universal Studios Japan, exploring animal cafes, and dining at top sushi spots.

• Meal Recommendations: From bento boxes at the airport to matcha ice cream on Day 10, every meal was tailored to my son's love for Japanese cuisine.

• Extras: Tips for traveling with a teen, like pre-booking popular attractions and respecting local customs.

The itinerary was thorough, naming specific places like Arashiyama for bamboo forests and animal encounters. It felt personal, like a friend had planned it just for us. The only hiccup? The initial server error, but the refund and retry made it seamless.

"Watching Manus browse the web and build my itinerary felt like having a travel agent who never sleeps."

Task 2: Redesigning My Website

Next, I pushed this AI agent to tackle something more complex: redesigning my website to outshine my current one, using my YouTube channel and existing site as references. I kept the prompt vague to test its task execution autonomy: "Design a better website than my current one, using my YouTube channel and website. Keep the color scheme and optimize for conversions."

The Process

The autonomous AI system dove into my YouTube channel, digging through the banner to find links, and analyzed my website. It hit an SSL certificate issue (something I didn't even know about!) but pivoted to an alternative approach. The right-hand panel showed it opening tabs, clicking dynamic elements, and scanning my content. It was like watching a curious intern explore my digital world.

After a few tries (and more refunded credits due to server load), this AI agent started coding in real-time. It used HTML, CSS, and JavaScript, building a new homepage in a Linux-based environment. The process was slow but mesmerizing—the autonomous AI agent was writing code, testing it, and refining it without my input.

The Result

The output was impressive for a first pass:

• New Homepage: A cleaner design with consistent colors, featuring sections like "New Videos Every Thursday and Friday," "Book a Call," and "Resources."

• Improvements Noted: The AI agent suggested fixing the SSL issue, integrating the YouTube API for auto-updating video thumbnails, and optimizing page load speeds.

• Code Output: I copied the HTML into an online viewer, and it rendered a functional site. It wasn't perfect—video thumbnails were placeholders since the autonomous AI agent couldn't access my backend—but it was a solid foundation.

The analysis was a bonus, pointing out flaws like slow load times and missing calls-to-action. It wasn't a complete overhaul, but for a vague prompt, this manus ai review shows the tool delivered a usable starting point. I could refine it further if I had more credits.

Task 3: Building a Web App

For my final task, I went big: "Create a full web application, like a directory, using HTML and JavaScript." I mentioned I'd tried something similar with another tool, Bolt, and wanted to see this autonomous AI agent's take. This was the toughest test, and I was nervous about burning my last credit.

The Process

The AI agent tackled this like a pro, switching to VS Code mode and writing code in a Linux environment. It structured a directory app, pulling inspiration from web resources (though it didn't specify which). The interface showed it testing the app, debugging errors, and deploying a live version. Server load caused a hiccup, but again, the autonomous AI agent refunded the credit, letting me retry.

The Result

The app was a basic directory with a clean UI, coded in HTML, CSS, and JavaScript. It included:

• Functionality: A searchable directory with placeholder data, ready for customization.

• Export Options: Like the itinerary, I could download the code or view it in a browser.

• Limitations: It lacked backend integration (e.g., a database), but for a beta tool with minimal prompting, it was a strong start.

The process wasn't flawless—server errors and the three-task limit were frustrating—but this AI automation tool's ability to self-correct and deliver functional code was a game-changer.

The Manus AI Interface: A Peek Behind the Curtain

The Manus interface is intuitive, with a left-hand menu for tasks, feedback, and settings (like light/dark mode). The right-hand panel is where the magic happens, toggling between:

• Browser View: Shows the autonomous AI agent navigating sites like a human, from YouTube to travel blogs.

• Terminal View: Displays Linux-based commands for coders who love the nitty-gritty.

• VS Code View: Real-time code writing, perfect for tracking progress.

You can attach files, track tasks, and even add knowledge bases to train this AI agent on specific skills. It's like a digital workshop where you watch your ideas come to life.

Challenges and Quirks

This manus ai review wouldn't be complete without mentioning that Manus isn't perfect. Here's what I ran into:

• Server Overload: High demand caused errors, but the auto-refunded credits softened the blow.

• Task Limits: Three tasks felt restrictive, especially for complex projects.

• Data Gaps: It struggled with real-time data like credit card points due to authentication barriers.

• Learning Curve: While user-friendly, maximizing this autonomous AI agent requires clear, specific prompts.

Despite these, the refund system and self-correction (like the "I'll resolve my own errors" message) made it forgiving for a first-time user.
