PromptSpace is the world's most comprehensive free prompt library for AI image generation and AI writing tools. Our library contains over 10,000 tested, copy-paste-ready prompts organized across 40+ categories and every major AI model — making it the go-to prompt library for designers, marketers, developers and creators worldwide.
Unlike paid prompt libraries that lock content behind subscriptions, every single prompt in our library is free. No account required. No rate limits. No email capture walls. Just browse the prompt library, find what you need, click Copy, and paste it straight into your AI tool of choice.
Our AI prompt library covers the full spectrum: image generation prompts for Midjourney, DALL-E 3, FLUX.1, Stable Diffusion and Gemini; text generation prompts for ChatGPT, Claude and Gemini; video prompts for Runway and Kling AI; and specialized collections like cinematic prompts, anime prompts, product photography prompts and realistic portrait prompts.
Every prompt in the library has been run at least once on its target AI model and reviewed for quality. We update the library weekly, retiring prompts that underperform and adding fresh ones that reflect current trends and model capabilities. This keeps the prompt library accurate and useful rather than bloated with outdated content.
Every section of the library is organized by model so you get prompts that actually work with your tool.

A prompt library is a structured, searchable collection of pre-written prompts designed for use with AI tools. Just as a code library saves developers from reinventing common functions, a prompt library saves AI users from reinventing prompts they need for recurring tasks.
When you visit a prompt library, you browse by category, keyword or AI model. You find a prompt that matches your goal, copy it, and paste it into the AI tool you are using. A good prompt library is organized, tested and frequently updated — so every prompt you copy is more likely to produce a great result than a prompt you write from scratch without practice.
Prompt libraries became popular with the rise of image generation models like Midjourney and Stable Diffusion in 2022–2023. These models are extremely sensitive to prompt phrasing — small word changes produce dramatically different outputs — so having a library of proven prompts became a significant productivity tool for designers and creators.
Today the best prompt libraries cover multiple AI types: image generation, text/writing, code generation and video generation. PromptSpace was built as a universal prompt library that covers all of these in one place, organized so that finding the right prompt takes seconds rather than minutes.
A prompt library is a curated collection of existing, tested prompts. A prompt generator creates new prompts dynamically based on your inputs. Both are useful but serve different needs.
Use a prompt library when: you need something that is proven to work, you are learning how prompts are structured, you want inspiration for a specific style or use case, or you need a starting template you can customize.
Use a prompt generator when: you have a very specific concept that is unlikely to exist in any library, you want to combine multiple styles in unusual ways, or you need to iterate rapidly on a unique brief. PromptSpace has both a prompt library and a free AI prompt generator so you can switch between approaches without leaving the site.
Filter the library by your current AI tool first. A ChatGPT prompt will not produce great results in Midjourney, and vice versa. PromptSpace tags every prompt with the exact model it was tested on.
Understand what each part of the prompt does. Notice the structure — subject, style, lighting, mood, technical parameters. Understanding the template helps you customize it for your own projects.
The best results come from treating library prompts as starting points. Replace generic placeholders with specifics — your product, your brand colors, your character description. A 10% customization often produces 10x better results.
Create a free PromptSpace account to save prompts to personal collections. Build your own private sub-library of the prompts that work best for your specific workflow, style and tools.
The library is updated weekly. New prompts reflect current model capabilities — models like Midjourney and GPT-4o update frequently and old prompts sometimes stop working optimally. New additions to the library are always tested on the latest model version.
