Prompt Enhancer (AI) — frequently asked questions
Is the Prompt Enhancer really free?
Yes. There is no premium tier. Each enhancement is one short Claude request, so it runs within a generous daily allowance per visitor (currently 200 a day); when it is used up you can still type prompts by hand and try the enhancer again tomorrow.
What does it produce?
A structured generation spec you can read and edit before anything is generated: subject, style, composition, lighting, colour palette, negative prompt, suggested aspect and size, and safety flags. For video targets it adds motion and camera notes; for icon sets, shape and colour; for documents, spreadsheets and slides, an outline of sections, columns or slides. The model-ready English version sits beside your own language.
Is the AI opt-in, and is my prompt stored or trained on?
Cloud AI is opt-in: a consent sheet appears once per session before your text leaves your device. Claude is called through our zero-retention proxy with structured outputs; nothing is trained on your prompt, nothing about its content is logged, and only a salted hash is kept for quota counting. Your prompt history lives on your device (IndexedDB) with export and clear buttons.
Which languages can I write in?
English, Hindi, Kannada, Malayalam, Tamil and Telugu, or a mix — "couple photo golden hour saree" works as well as a full sentence. Set Spec language to Auto to keep your language and receive the English version the generation models understand best.
Can it make unsafe prompts "work"?
No. The enhancer applies the same moderation rules as the generators: it refuses to build prompts that depict real people, minors in sexual contexts, non-consensual imagery, hate symbols or extremist content, and it flags brand names so you can replace them with a description. Blocked requests return a plain error; only counts are recorded.
Can I run the spec directly?
Yes. Run in AI Studio opens Generate Image, Generate Video, Generate Icon Set, Generate PDF, Generate Slides or Generate Spreadsheet with every field pre-filled, and the spec is saved on your device so you can reuse or share it.
