Its core is a searchable index of AI products, each assigned to one or more categories, so a visitor hunting for, say, a background remover, a meeting assistant, or a vector database can browse by use case instead of relying on scattered social posts. The site reports more than 2,600 indexed tools and organizes them into an extensive taxonomy spanning marketing, development, health, legal, robotics, and hundreds of smaller niches. Beyond plain listings, Altern adds editorial and community layers. Curated lists bundle tools by scenario; a leaderboard ranks widely used products; and a "Buildboard" runs a weekly competition where new tools gather votes and the top entries are highlighted. A newsletter rounds out the offering, giving subscribers a periodic digest of new and noteworthy AI products. Altern is an independent third-party directory and is not affiliated with any of the vendors it lists. Listings are curated and can be submitted by makers, so pricing and feature details should always be confirmed on the vendor's own site before purchase. **Pricing & Plans:** Free to browse and use.
