What are the five modes? ▼
Prompt turns a typed idea into a detailed prompt. Image analyzes a photo. Video watches a short clip (8–15 seconds). Master takes a simple prompt and expands it into a detailed, reusable template. JSON turns a simple prompt into structured JSON. Pick whichever fits what you need.
What is a "master prompt"? ▼
A master prompt is a bigger, structured version of a normal prompt — with labelled sections for subject, camera, lighting, mood, style, and what to avoid. It's great when you want consistent results across many videos: keep the structure and just swap the subject each time.
When would I use the JSON prompt? ▼
JSON is a structured, code-like format that some advanced tools and APIs accept for precise control. If you're a developer or using a tool that asks for JSON, paste a simple prompt and click Create JSON. Most beginners on Kling, Runway, or Veo can stick with the normal prompt.
Is it really free? ▼
Yes. The tool is completely free to use — no account, no credit card, and nothing to install.
Why must videos be 8–15 seconds? ▼
Most AI video generators create clips in that range, so a prompt built from an 8–15 second reference translates best. If your video is longer, trim it first with a free editor like Clipchamp or iMovie.
Is my data safe? ▼
Your files are sent only to generate your prompt and are not stored on our servers afterward. See our Privacy Policy for full details.
The prompt didn't work in my tool — now what? ▼
Try Regenerate for a fresh variation, or edit the prompt directly. Each AI platform responds a little differently, so small tweaks often help. Also double-check you picked the right platform.
Which AI platforms are supported? ▼
Seedance, Veo 3, Grok, Kling AI, and Runway ML — plus a Universal option that works with any AI generator. Just choose your target before generating and the prompt is tailored to it.
Do I need any technical skills? ▼
None at all. If you can type an idea or drag a file, you can use this tool. Everything else happens automatically.
Can I use the prompts commercially? ▼
The prompts are yours to use however you like. Just remember that whatever you create on a third-party AI platform is also governed by that platform's own terms.
