About PromptDen
PromptDen is a community-driven platform for prompt engineering, discovery, and sharing. Users can explore, discover, and share prompts designed for various AI models including ChatGPT, Claude, Gemini, MidJourney, Stable Diffusion, DALL-E, and Firefly. The platform caters to both text and image prompt creators, offering a marketplace where users can upload their own prompts and explore prompts created by others. The platform also features a browser extension for ChatGPT, Claude, and Gemini that integrates directly into these AI tools. One limitation is that the platform primarily functions as a repository and community space rather than offering tools to generate prompts from scratch.

Our verdict on PromptDen
3.5/5 · 3 sources · reviewed August 3, 2026
PromptDen is a free, small-scale community for sharing ChatGPT, Claude, Midjourney and Gemini prompts, paired with a modestly rated browser extension that brings saved prompts into those chat windows. Early adopters liked it and no user complaints turn up anywhere online, but that is partly because almost nobody has reviewed it yet, the extension has only 13 ratings despite roughly 3,000 installs. Worth a look since it costs nothing to try, but treat it as an unproven pick rather than a heavily vetted one.
What users praise
- Early users described the browser extension's interface as intuitive and said it solved a real problem organizing and reusing prompts, with one calling it the only paid extension they use.
- The site draws a genuinely large and active pool of shared prompts spanning multiple AI models, and the browser extension brings that library directly into the chat window instead of requiring a separate tab.
What users complain about
- Because anyone can submit, prompt quality varies a lot, and the paid marketplace for buying and selling prompts sees limited activity.
- Outside scrutiny is thin: the browser extension carries only 13 ratings despite roughly 3,000 installs, so its 3.7-star average rests on a very small sample.
Not for: Skip it if you need a large, heavily vetted body of independent reviews before trusting a tool, since open submissions mean prompt quality varies and outside scrutiny of PromptDen is still thin.
