Three places to work with prompts
Pick the studio when you have a specific idea to shape, and a library when you want a proven starting point.
- Prompt Studio: draft a prompt from an idea, or paste an existing one to refine it, with starting templates for popular image and video models.
- AI image prompt library: copy-ready image prompts you can search and filter by style, then copy in one tap.
- AI video prompt library: written prompts for marketing, reels, product ads, cinematic shots and more, each with customisable slots. Many are free to read, copy and download.
Draft a prompt in Prompt Studio
Choose a starting tool
Open /imgprompt and pick the focused tool that matches your goal: turn an idea into a full prompt, refine an existing prompt, or write for image, video or cinematic output.
Describe the idea
Write the subject, setting and mood in plain words. Use the controls to set style, framing, lighting and the target model.
Check the structure
Read the checklist value. It is a local heuristic based on length, specificity and the controls you chose, meant to flag vague prompts.
Copy and render
Copy the prompt and paste it into your image or video generator. Check that model's current syntax before rendering.
Customising video prompts
Prompts in the video library mark the parts you should change as uppercase tokens in square brackets, such as [BRAND_NAME] or [CTA_2]. The prompt page counts which variables you still need to fill in, and the copy and download actions use your values, so the text you paste into a video generator is complete.
Helper tools for prompt work
A few utilities make prompt work smoother: the Words to Tokens Estimator gives a rough token count before you hit a model's limit, the Prompt Text Cleaner strips stray formatting from pasted text, and the AI Prompt Organizer keeps the prompts you reuse in one place. To choose a generator, see the AI tools directory guide.

Frequently asked questions
Which AI models does Prompt Studio support?
It provides starting templates for models including OpenArt, Midjourney, Flux, Ideogram, Leonardo, DALL-E, Stable Diffusion, Runway, Pika, Kling, Luma and Hailuo. Check each provider's current syntax before rendering.
Do I need my own API key to use Prompt Studio?
No. The studio has a built-in prompt engine. Features that use a hosted model show their limits when you use them.
Can I use AI images commercially if I use these prompts?
A prompt does not grant any usage rights. Check the terms of the model provider and the rights to any brands, people or source images before commercial use.
