Free AI tools by category
184 listings across 30 categories are free: the maker charges nothing for the product itself. Each section below is ordered by upvotes.
A further 830 listings run a free tier alongside paid plans. Those are marked freemium and are not on this page, because a free tier is not a free tool. Browse everything to include them, or start from a category.
