Frequently asked questions

Voice to prompt

Can I speak my prompt instead of typing it?
Yes. Tap the mic, talk the way you normally would, and PromptVault turns your spoken thoughts into a clean, ready-to-use AI prompt. Nothing is sent until you press Improve.
Does voice to prompt work in other languages?
Yes. Dictation uses your browser's speech recognition, and the improved prompt stays in the language you spoke, including Spanish and Arabic.
Is the audio stored?
No. Speech is converted to text in your browser and the original audio is never kept.

Image and screenshot to prompt

How does image to prompt work?
Tap + and add a photo or screenshot. PromptVault describes what it sees and drafts a prompt you can edit before improving it for ChatGPT, Midjourney, Flux, Runway and more.
Can I turn a screenshot into a prompt?
Yes. Screenshots of designs, apps, error messages or reference art all work. You review the description before anything is improved.
Will it invent details that are not in my image?
It is instructed to describe only what is visible and keep your stated facts. Always check the result before using it.

Prompt generator

Is this AI prompt generator free?
Yes. You can generate and improve prompts without signing up.
Which AI models does it support?
ChatGPT, Claude, Gemini, DeepSeek, Midjourney, Flux, Runway and Lovable, with tips for compatible models.
Can I start from voice or an image?
Yes. Type, talk into the mic, or add a screenshot or photo.

Prompt improver

What does a prompt improver change?
It fixes grammar, adds missing context and structure, and removes fluff while keeping your facts and meaning.
Will it make my prompt much longer?
No. Rewrites stay proportional, and long prompts get surgical edits instead of padding.
Is it free?
Yes, with no sign-up required.

General and privacy

Do I need an account?
No. You can improve prompts as a guest. Signing in is only needed to save prompts to your own vault.
Is my prompt used to train AI models?
No. PromptVault does not train models on what you type, and example prompts on the site are fictional.
Will the improved prompt stay in my language?
Yes. The rewrite keeps the language you wrote or spoke in, including Spanish and Arabic.
