Opten: AI Image & Video Prompt Optimizer
Optimize AI prompts for Midjourney, Seedance & 60+ models
Opten is an AI prompt optimizer for image and video generation. One click scores your prompt 0–100 for the exact model you're using, shows what to fix, and enhances it automatically. 61 models supported: Midjourney, Nano Banana, Veo 3.1, Kling, Seedance, Flux, GPT Image, Runway, Wan, LTX-2 + 50 more. Every model has its own rules — Opten knows them all. Works inside syntx.ai, higgsfield.ai, freepik.com and magnific.com. No copy-paste, no tab switching.
Hey Product Hunt 👋
I'm Vlad, solo founder. I built Opten because I was burning through AI credits like crazy.
Here's what kept happening: I'd write a prompt that nailed it in Midjourney, paste the same thing into Kling for a video — garbage. Try Seedance — also garbage, but in a different way. Turns out Seedance ignores negative prompts entirely. Kling needs explicit camera motion. Midjourney prefers short. Nano Banana wants natural-language layout descriptions. Veo 3.1 needs explicit shot framing. Each model is its own language.
There are plenty of "AI prompt optimizers" out there, but they all give generic advice — "be more specific," "add lighting." Useless. The real answer is model-specific: what works for one breaks another.
So I spent months writing skill files for each model — 61 of them now, covering Midjourney, Nano Banana, Veo 3.1, Kling, Seedance, Flux, GPT Image, Runway, Wan, LTX-2 and 50+ more. Opten reads which model you're on, scores your prompt 0–100 against that model's actual rules, and rewrites it in one click. Works directly inside syntx.ai, higgsfield.ai, freepik.com and magnific.com — no copy-paste, no tab switching.
Three things I'd love your feedback on:
1. Which model are you using most right now? Tells me what skill to improve next.
2. What's the worst "generic prompt advice" you've ever gotten? I'll write a counter-rule.
3. Which platform should I support next? (Aitrix, OpenRouter, Flora are on the shortlist)
Happy to answer anything — Claude Haiku 4.5 under the hood, Vercel proxy, all skill files are markdown.
Thanks for trying it 🚀
