About
AI Compare Ninja connects AI tools with how to use them. The first pillar is the tool side: a free catalog of 1047 AI tools. Each tool page covers features, free access, prices, plans and limits, sourced from the official vendor pages. Missing figures stay marked as not published.
The second pillar is application: prompt templates, Skills, Loops, ready-made agents, guides and the AI glossary show how to use AI in your business, in your job and in your free time. Prompts, Skills, Loops and agents name the tools they work with.
The catalogue currently holds 1047 checked tools in 10 categories, available in 8 languages. Every entry names at least one official source.
Who is behind it
The founder of the project is Martin Müller. As a computer scientist (Diplom & Master's) he looks back on years of software development in audio, AR/VR and the web. His focus is on modern AI tools, AI-assisted software engineering, and the interfaces between AI and robotics. He and his team maintain the catalogue.
How we check
Sourced only
A tool enters the catalogue once its prices, plans and limits have been checked against the official vendor page. Where the vendor does not state a figure, we mark it as not published. We do not estimate and we do not extrapolate.
Source, not assertion
Every entry names the vendor page it came from, in plain text. Where the vendor page contradicts our entry, the vendor page stands.
Checked twice
Every published tool is checked automatically against the official vendor page each day. Once a month a second check with a different method is added.
Prices without conversion
Prices stay in the currency the vendor states them in, separated by pricing region. We convert no currencies, because a converted amount does not reflect the actual invoice.
Order without judgement
Search results are ordered by Task match by default, meaning how well the sourced tool facts fit the task you typed. Category and task lists are alphabetical by default. In search results and on category and task pages, you can switch to Free access first. None of these orderings is a quality ranking. The related tools on each detail page are chosen alphabetically as well. For task matching, exact product names and explicitly requested providers carry particularly high weight. Matching name prefixes and phrases, followed by editorial assignments to tasks, segments and primary or additional tools, also matter. Individual matches in feature descriptions and category overlap generally carry less weight; text similarity adds to these signals. Explicit requests such as free, open source or no subscription adjust the weights; exclusions and selected tasks restrict the results. Signals are combined, so their order may vary by query. Free access first puts free access and trials ahead of paid entries, sorting alphabetically within each group. Alphabetical sorts by tool name. Commissions and affiliate links do not increase the search score.
Inclusion criteria
We list an AI if it meets these three criteria:
- Real AI relevance: artificial intelligence is an essential part of the product.
- The tool works and is reachable.
- It is legal: no scam, no malware, nothing unlawful. We do not list tools that name themselves after other companies’ AI brands without belonging to their provider.
There are no other reasons for rejection. Inclusion depends solely on our criteria; free listing is available.
There are no other reasons for rejection. Inclusion depends solely on our criteria. The express review only speeds up the review; it influences neither the decision nor placement or rating.
Found an error?
We check against the vendor page and correct or withdraw the entry. Every tool page carries a direct link for this.
