Has Potential
Checked this out a bit. Bought it because I see good potential with it. I will compare it to Straico and Zemith both of which were similar and had a lifetime deal on here at one point. I would say of the 3 this one not as good though keep in mind I tend to focus more on the AI chat itself here are some thoughts on it (will suggest features on their website at some point).
AI:
While it says the AI are the best ones it is actually missing some of the newer ones right now (it might get it later but shows it is slower to roll out). For example o3 and o4 mini is missing. Edit: Now has Grok 4. Opus 4 is missing (Edit: Zemith and Straico have it) Doesn't have a search feature like Straico or Zemith however Ninja AI Tools has it on the road map.
The PDF is not good. First it wasn't taking my pdf easily saying it failed but then it worked even if saying it failed (not showing the cover). It forgets any follow up questions. It also was basic for example I asked it the difference between Fictionalism and Pretense Theory in my pdf but it could only say the difference was Pretense dealt with Make-Believe and Fictionalism, Fiction but this distinction is already in the name of the theories so not very informative and I asked it a few times to try to get more out of it. However the roadblock shows this is in the works. This would be a great feature if it was much better.
The image creation isn't my thing so can't say except I like to use real images and make them into anime versions but Ninja AI tools does not have this option. You can only make a prompt generation. Would also be nice to make an image into a video.
One strength is it beats Straico on being able to use 6 AI to compare however unlike Straico there is no option to combine the responses which would make it definitely superior whereas rn it's debatable especially since Straico has the better AI for chat.
Edit: This isn't to say the AI are very bad, I bought it because it still has some of the most advanced ones like Sonnet 4, Gemini 2.5, and Grok 4 so thinking it will update but the fact it's missing some shows it's a tad on the slower end.
I haven't tried it's writing library but it looks quite nice with a good assortment of them that look quite helpful and not like the useless ones I often see. Also Ninja Tools AI has a nice mind map one can use.
Overall it has some nice features and ones in the development I would not have gotten it if I didn't think it would be worth it. It seems to have a good amount of messages, images and things one can use so definitely worth it.
Few suggestions in no particular order:
AI - Should be the first thing always. Make sure they are the most up to date and advanced. It shows easily whether one is lagging or not also.
PDF, Search, deep Research, Kling, Chat with YouTube: Seem to already be in the works.
Images - Let me upload a real image of say me and let me use GPT image to turn it into an anime version
Video - similar but let me turn an image into a video (Kling does this)
Have the AI chats be able to merge responses.
Source Library: This one is a big one for me. I often do research or debates and I need my sources. 30-50 books/sources my AI could access would help immensely.
Eraser: An image Eraser Zemith has a great one and is as good as Galaxy phone AI in erasing things from an image.
Audio/video transcription: Neither Zemith nor Straico has this. 1MinAI has it and Ideaaidze but rn they are outdated using the old Whisper from OPENAI and they can only take something like 25MB which isn't much. Beating them on this would make it a go to.
Add prompts.
These are my thoughts for now. New product so will grow faster in the future. Has lots of various things. Good amount one can use of them. Lifetime deal rn. Pretty up to date and new features make it promising enough for me to recommend buy now before it gets better and is too late. These are things that hopefully you catch in the infancy and glad you did.

Edited Jul 18, 2025Thank you so much for your thoughtful 3-taco review on AppSumo and for taking the time to share such detailed feedback—we truly appreciate it! We're delighted to hear you see the potential in NinjaTools.ai, especially with features like our writing library, mind map tool, and generous limits on messages, images, and more. It's great that you think it's worth buying now as a lifetime deal, and your comparisons to Straico and Zemith are super helpful for us to keep improving. Your support and recommendations mean the world!

We're sorry to hear about some of the frustrations, like the missing models. We actually had o3 before, but since it's super expensive, we removed it while providing other advanced options like Sonnet 4, Gemini 2.5, and Grok 3 mini. We're exploring new pricing models to make it feasible, and we'll add all the other models you mentioned (like o4 mini, Grok 4, and Opus 4) once that's sorted. We aim to stay up-to-date with the latest AIs, so stay tuned!
On the PDF chat, we completely agree it's not where it should be right now—the upload issues, forgetfulness on follow-ups, and basic responses (like with Fictionalism vs. Pretense Theory) are things we're actively working to fix for a much better experience. Thanks for highlighting that!
For images, we don't currently support uploading real images for transformations like turning them into anime versions, but we love the idea and encourage you to add it to our public roadmap at: doc.ninjatools.ai/docs/public-roadmap-and-feature-request. Image to video (using tools like Kling) is already on the roadmap, and we'll prioritize it.
We hear you on the AI comparison strength—being able to use 6 models at once is a big plus, but adding an option to merge responses is a great suggestion we'll consider. The search feature, deep research, chat with YouTube, and Kling enhancements are also on our roadmap, and we're adding search source references (like a library for 30-50 books/sources for research/debates) as you recommended. Audio/video transcription is an excellent idea—we'll add it to the roadmap too, aiming to beat competitors with better limits and updated tech like newer Whisper versions. An image eraser tool and custom prompt additions are fantastic suggestions; feel free to submit them directly on the roadmap for community voting!
We've been shipping updates daily, including fixes for authentication issues, artifact bugs, and additions like dark mode and email auth, to make NinjaTools even stronger.
