Markets come from the alternatives Product Hunt lists for each product. Groups are drawn by Claude from a few words on what each product is, so read them as a first cut. Launch counts are of the products we have pages for, which lean recent: compare groups with each other rather than reading them as a census. Product Hunt categories here: Chrome Extensions (68), AI Chatbots (23), Prompt Engineering Tools (11). Updated 2026-10-14.
