Ninja AI Review: My Full Hands-On Test of SuperNinja & Deep Research

I’ve tested dozens of AI tools, ChatGPT, Claude, Gemini, Copilot, Midjourney, Leeco AI, Codeium, and every time I end up switching between 6–7 tools just to finish simple daily tasks.
In late 2025, I noticed an unusual pattern on Trustpilot: users saying Ninja AI replaced 4–5 of their subscriptions. That was the moment I became curious.

I didn’t want another chatbot.
I wanted a workspace, a single hub where I could research, code, write, generate images, build automations, and run complex tasks.

That’s when I opened:
https://www.myninja.ai
https://www.ninjatech.ai

24 hours later, Ninja AI became part of my daily workflow.

What follows is my real 30+ day hands-on experience, with data, real usage, real flaws, and real wins.

What Exactly Is Ninja AI? 

Ninja AI is an all-in-one AI workspace with two identities:

Ninja Mode: A powerful multi-model chat (40+ models like GPT-5, Claude 3.7, Gemini 2.5, DeepSeek).

SuperNinja: A fully autonomous agent that runs inside its own virtual computer and executes real tasks, coding, analysis, file operations, automation, and more.

You access everything in one dashboard:
https://super.myninja.ai

Instead of bouncing between ChatGPT, Claude, Google Docs, VS Code, and image tools… everything lives inside Ninja AI.

For someone like me, juggling content, coding, SEO research, and client documents, this was a massive shift.

Why I Decided to Test Ninja AI Seriously

I made the decision for three reasons:

1. Trustpilot Reviews Looked Surprisingly Honest

Ninja AI had:

4.0★ out of ~197 reviews

Genuine user stories

People saying they use it every day for real work

Multiple reviews saying “it replaced my ChatGPT subscription”

2. Engineering-Focused Product

Ninja AI heavily marketed developer features, including:

“Fast Deep Coder”

GitHub integration

Virtual-machine workflows

Full-stack automation

As someone who writes + codes + analyzes, that combination felt perfect.

3. 40+ Models in One Workspace

This mattered more than I initially expected.
Switching between GPT-5, Claude, Gemini, DeepSeek, and Nova inside the same window saved time and subscription costs instantly.

My First Impressions Using Ninja AI

The Workspace Experience Felt Like an AI Operating System

When I entered the workspace at https://super.myninja.ai, the UI felt like:

  • A chat window
  • A VS Code panel
  • A research lab
  • A task automation screen
  • An image/video studio

Everything was integrated.
Everything was persistent.
And everything felt task-oriented, not chat-oriented.

No Setup, No Installs, No Technical Hurdles

SuperNinja uses a cloud virtual machine.
So coding tasks, app building, PDF export, and analysis all happened without installing anything on my PC.

My Experience With SuperNinja (The Agent That Actually Works)

SuperNinja isn't a “tool that replies.”
It performs actual work.

Real Tasks I Completed Using SuperNinja

Here are actual tasks I ran on the SuperNinja VM:

  • Built a complete HTML/CSS dashboard
  • Cleaned a CSV with 15,000+ messy entries
  • Generated a professional PDF report
  • Created SEO content with citations
  • Ran Python scripts without installing Python locally
  • Organized folder structures
  • Exported output to ZIP files
  • Debugged code with detailed reasoning
  • Created a small Flask app automatically

All of this felt like having a small engineering team tucked inside a browser tab.

How It Compares to ChatGPT’s Agents

ChatGPT agents are powerful, but:

  • They don’t run a real VM.
  • They don’t let you inspect files, run code, and generate multi-file outputs.
  • They don’t let you manage an actual file system.

SuperNinja handles those things.

This was the first time I saw an agent actually behave like a digital employee rather than a large-language-parrot.

Deep Research 2.0: The Feature I Didn’t Know I Needed

Deep Research is one of Ninja AI’s strongest modules.

It does multi-step, cited research automatically.

Real Results from My Research Tests

Using Deep Research, I generated:

  • A 17-page competitor analysis
  • A complete market overview for “AI learning tools”
  • A keyword map with traffic sources
  • A policy breakdown using PDFs
  • An SEO outline structured with citations

The accuracy felt noticeably higher than ChatGPT on factual tasks, possibly because Ninja combines multiple models in the background.

Their benchmark claims around 91.2% accuracy on hallucination tests.
I couldn’t test that scientifically, but based on experience, the research outputs were significantly more grounded.

Ninja AI as a Developer Tool

This is where Ninja AI shines.

Coding With Fast Deep Coder

The engineering solutions page (https://www.ninjatech.ai/engineering-solutions) explains how Ninja AI uses Fast Deep Coder—a specialized model for coding.

In my testing, I noticed:

  • Faster reasoning
  • Cleaner code formatting
  • More consistent best practices
  • Better ability to explain logic
  • Fewer hallucinated imports
  • Stronger debugging
  • Clearer file structure creation

VS-Code Style Editor + GitHub Integration

This combination is powerful.

I connected GitHub and could:

  • Generate commits
  • Create pull requests
  • Fix issues
  • Write documentation
  • Produce tests for CI workflows

It felt surprisingly close to a lightweight cloud IDE.

Multi-Model Power (The Real Cost Saver)

Ninja AI offers more than 40 models:

  • GPT-5 Turbo
  • GPT-4.1
  • Claude 3.7
  • Gemini 2.5 Pro
  • DeepSeek R1, V3
  • Amazon Nova
  • Meta Llama 3.1 + 4
  • Mistral & Mixtral
  • FLUX, Stable Diffusion, Imagen for images

Instead of paying for all these separately, I could switch models instantly in the same chat.

For example:

  • Claude 3.7 for reasoning
  • GPT-5 for writing
  • Gemini 2.5 for structured logic
  • DeepSeek for hardcore coding
  • Llama 4 for speed

This became one of the most underrated advantages.

My Daily Workflow With Ninja AI

This is how I used Ninja AI over 30 days:

Morning – Research & Planning

  • Used Deep Research for briefs
  • Created To-Do plans for clients
  • Compared tools & pricing

Midday – Coding & Automation

  • Built scripts with Fast Deep Coder
  • Ran them on SuperNinja
  • Exported output via ZIP

Afternoon – Content Creation

  • Generated SEO content
  • Built LinkedIn posts
  • Created images for blogs

End of Day – Reporting

  • Asked Ninja to generate summary reports
  • Prepared PDF deliverables
  • Organized files inside the VM

It became my full productivity environment.

User Reviews 

Android App Ratings

On Google Play:
3.7★ with 10K+ downloads
https://play.google.com/store/apps/details?id=ct.ctapp

iOS App Ratings

Around 4.3★, but fewer reviews.

The mobile version is functional, but not on par with the web version—at least not yet.

Ninja AI’s Weak Points (My Honest Observations)

No tool is perfect. Ninja AI’s flaws include:

  • Occasional agents looping on complex tasks
  • Slower response during peak hours
  • A learning curve for new users
  • UI not as polished as consumer products
  • Some stacks (like PHP) show weaker performance
  • Mobile apps still catching up
  • Overwhelming for beginners

These issues appeared occasionally, not daily, but they’re worth noting.

Pricing and Which Plan I Recommend

Ninja AI offers several tiers:


From my usage, the mid-tier SuperNinja plan gave the best ROI.

It replaced:

  • ChatGPT Plus
  • Claude Pro
  • Gemini Advanced
  • Image tools
  • Coding tools

I literally saved money with this switch.

Final Verdict: Is Ninja AI Worth it?

After using Ninja AI every day, I can say this—it genuinely became part of my routine, not just another tool I tested and forgot. It helped me research faster, code smarter, organize complex tasks, and create content without juggling 5–6 different platforms. It feels less like a chatbot and more like a personal workspace that grows with me, adapts to my workflow, and actually saves my time. It’s not perfect, but for someone who wants a reliable AI partner that can do real work, Ninja AI has earned its place on my taskbar. If you're tired of fragmented tools and want one powerful hub, this is the one I’d personally recommend trying.
