What PromptMine is
PromptMine is a free, searchable library of 18,309+ AI prompts across 12 categories. Every prompt is free to read and copy. The 21 curated originals are written for real work and tested on frontier models — and each one carries a usage note on when to reach for it and where it breaks, which is the part most prompt lists leave out.
what’s free
Reading every prompt is free, forever — no account needed to browse. A free account copies 10 prompts a day, saves favourites, and previews the first step of any workflow pack.
what Pro adds
Pro sells the tooling around the prompts, never access to the prompts themselves: unlimited copies, a variable generator that fills a prompt’s {blanks} into a ready-to-paste result, all 39 workflow packs in full, and batch export to CSV/JSON. It’s $4.90/month, $49/year, or $99 once for lifetime. See pricing →
workflow packs
A workflow pack is an ordered chain of prompts that walks through one real task end to end — not a themed pile of prompts. “Ship a feature safely” goes from understanding the code, to pinning behaviour with tests, to building, to reviewing the diff. There are 39 packs across 12 industries. Browse packs →
where the prompts come from
Two sources, clearly separated. The 21 curated originals are written and tested in-house. The rest are imported from openly-licensed community collections — each prompt page lists its source. Curated originals are what we put forward; the imported library is there so you can search broadly.
independence
PromptMine is an independent site, not affiliated with OpenAI, Anthropic, Google, xAI, Meta or DeepSeek. Model names are used descriptively — to say which models a prompt was tested on, nothing more.
