Our Take

prompts.chat bonked it — 143k GitHub stars makes this the biggest open-source prompt library on the platform, and it's been doing this since December 2022 before "prompt engineering" was even a phrase people threw around at founders. Originally built for ChatGPT but now works across Claude, Gemini, Llama, basically anywhere you're chatting with an AI, and they've got self-hosting with custom branding and auth if you want your own private setup. The CC0 public domain license means you can fork it, sell it, remix it, no attribution required — and the academic credibility is actually insane, Harvard and Columbia have cited this thing.

A curated collection of prompt examples for AI chat models. Originally created for ChatGPT, these prompts work great with any modern AI assistant.
