Key features	One-click installer bundling Stable Diffusion with no manual dependency setup Fully offline, on-device generation with no required data upload Text-to-image, image-to-image, in-painting, and out-painting in one interface Custom model support for loading community-trained checkpoints Built-in upscaling for increasing output resolution	Searchable index of millions of community-submitted AI prompts across multiple models Coverage spans Midjourney, Stable Diffusion, Sora, FLUX, Nano Banana, and other current generative models Curated "best of" prompt collections organized by model and style Academy section with structured lessons on prompt engineering AI model reference library covering both image and video generation tools
Pros	Entirely free with no subscription, credit system, or paywalled features Offline generation keeps prompts and images off third-party servers One-click install removes the Python/dependency setup barrier most local Stable Diffusion guides require	Free to search and browse, with no account required to find usable prompts Coverage of newer video models like Sora and Veo alongside established image models Backing from ElevenYellow adds resourcing after the 2024 acquisition
Cons	macOS only, so Windows and Linux users cannot run it Generation speed depends entirely on the local Mac's hardware, slower on older Intel models Solo-developer maintenance model means updates and support depend on one person's bandwidth	Quality of individual community-submitted prompts is inconsistent and requires some judgment to filter Does not generate images itself, so it's a companion tool rather than a standalone creation platform Some featured prompt examples lean toward mature or provocative imagery, which won't suit every workplace context
Company	Divam Gupta, founded 2022	PromptHero (ElevenYellow), founded 2022
