VideoPrompt
Free on-device AI video prompt generator — private
VideoPrompt is a free, on-device AI prompt toolkit for AI video. 100+ hand-written prompt templates across 21 platforms (Sora, Kling, Runway, Veo, Pika, Seedance...), plus 5 local AI engines: text / video / image to prompt, a prompt improver, and a character-lock card generator for AI short dramas. Real models (Qwen2.5 + Florence-2) run in your browser via WebGPU — nothing is uploaded, no sign-up. 14 languages. The template library is open source (CC-BY-4.0) with a pip CLI.
Hey Product Hunt! 👋
VideoPrompt started with a simple frustration: every AI video platform wants a different prompt style, and "prompt generators" on the web all send your ideas and videos to their servers.
So I built the opposite:
• 100% on-device — real Qwen2.5 & Florence-2 models run in your browser via WebGPU. Your videos and images never leave your device.
• 21 platforms, 100+ hand-written templates — Sora, Kling, Runway, Veo, Pika, Seedance and more, each with camera/lighting/style controls.
• 5 local engines — text→prompt, video→prompt, image→prompt, prompt improver, and a character-lock card generator for AI short dramas (same face, same outfit in every shot).
• 14 languages, free, no sign-up.
And the part I'm proudest of: the entire template library is open source under CC-BY-4.0, with a pip CLI (vp-templates) and a public repo — because prompts shouldn't be locked in silos.
Open DevTools: no keys, no analytics on the AI pages, no uploads. Built with WebGPU, WebLLM and Cloudflare Workers. Feedback welcome 👇
