Frequently Asked Questions About Categories

Common questions about how our AI tool categories work

Think about what problem you are trying to solve. If you need help writing blog posts, emails, or marketing copy, start with Writing Tools. For visual content like social media graphics or product photos, head to Image Tools. If you are a developer looking to code faster, Coding Tools is your best bet. When in doubt, browse multiple categories — many AI tools span several use cases, and our directory makes cross-category discovery easy.

The example tools shown in each category represent a mix of popular, highly-rated, and up-and-coming AI tools that our editorial team has reviewed and recommends checking out. They are not an exhaustive ranking — we include a variety so you can compare different approaches. For detailed comparisons, ratings, and full reviews, check each tool's dedicated listing page where we break down features, pricing, pros, and cons.

The AI landscape evolves fast, and so do we. We add new tools weekly and regularly evaluate whether new categories are needed as AI capabilities expand. If a trend like AI legal tools or AI healthcare tools becomes significant enough to warrant its own category, we'll create one. You can always suggest a new category or tool through our Submit a Tool page — we genuinely read every submission.

Yes — many AI tools are versatile enough to fit multiple categories. For example, Notion AI works as both a Writing Tool and a Productivity Tool. RunwayML spans both Video Tools and Image Tools. We list tools in every category where they genuinely deliver value, so you might see the same tool pop up in multiple places. Each listing is tailored to that category's context.

We list both free and paid AI tools across all categories. Many tools offer generous free tiers — ChatGPT, Claude, and Perplexity AI all have free versions with solid functionality. We clearly mark pricing models on each tool's listing so you can filter by what fits your budget. Our philosophy is that great AI tools should be discoverable regardless of price point.

Head over to our Submit a Tool page and fill out the form with your tool's details — name, URL, category, pricing, and a short description. Our team manually reviews every submission, tests the tool hands-on, and if it meets our quality bar, we'll add it to the appropriate category (or categories) with a detailed listing. The review process typically takes 5-10 business days.
