CLUSTER PROMPTS-REFINE-WEB · 21 ENTRIES · EARLIEST ENTRY 2025-08-16

AI prompt engineering tools

The cluster consists of web and local tools for crafting, refining, managing, sharing, and structuring prompts for large language models and generative AI, including template libraries, IDEs, and format converters. Dated entries run from May 2025 through June 2026, appearing one or two per month with no clear upward or downward trend, so the timeline is steady but unremarkable. Traction is led by AmazingDraw with 22 stars, far ahead of prompt-manager (3) and PromtHub (2).

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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
