Free AI prompts

Free AI prompts are ready-to-use instructions you can reveal and run at no cost — for writing, coding, marketing, images, and everything in between. Free and premium prompts that members submit pass the same review by a person, so a free prompt is held to the same quality standard, not a lower one. Browse by model or category, reveal the full prompt text, and run it live in the in-app Playground to see the output on your own input. Start free, and only subscribe if you later want other creators' premium prompts and skills.

Frequently asked

Where can I find the best free AI prompts?

Prompt Dock's free collection gathers prompts you can reveal and run without paying. Free and premium prompts that members submit go through the same review by a person, so quality isn't the trade-off. Filter by model or category, reveal the full text, and run it live in the Playground to judge it on your own input.

Are the free prompts really free?

Yes. Free prompts can be revealed and run right away at no cost — no trial, no card. Only prompts an author marks premium require a subscription to unlock. You can build an entire workflow from free prompts and upgrade later only if you want others' premium work.

Which AI models do the free prompts work with?

Free prompts are written for models like Claude, GPT/ChatGPT, Gemini, Midjourney, and DALL·E, and each one names the model its author recommends. The Playground runs a prompt on your own input with a model you pick. Claude, GPT, Gemini, Llama, Grok, and more run on every plan. Some models run on the Master plan only.
