AI prompt engineering tools
The cluster consists of web-based tools for creating, refining, testing, and optimizing prompts for AI models, including enhancers, evaluators, playgrounds, and libraries, with some targeting specific AI development platforms. The dated entry history shows a steady stream of new products from February 2025 through June 2026, with peaks of 5 entries in June 2025 and 3 in January 2026. The products with the highest activity signal are cotor.ia, cargarge-admin-2, and PROMPT-GENIE1, each showing 0 stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
