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. Every free prompt on Prompt Dock passes the same human review as our premium prompts, 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 access to other creators' premium prompts.
