How Opten came to be
I'm Vlad Voronezhtsev — I make YouTube Shorts about AI image and video generation (channel @v.voronezhtsev, 4,500+ subscribers, 54 videos, around 7 million views in a year). I'm a web designer by trade, but in 2024 I went all in on AI creative work: Midjourney, Kling, Veo, Sora, Nano Banana, Seedance — I tried just about everything that shipped.
The more content I made, the more I kept seeing the same pattern: people open Syntx, Higgsfield, Freepik or Magnific, write a prompt "off the cuff", get a mediocre result — and conclude that the model is bad. When in fact there's a powerful model under the hood, it just doesn't understand what they want. Prompting is a skill. Nobody really teaches it.
I started Opten in fall 2025 for myself — I needed a tool that would show in real time how well my prompt "lands" for a specific model and what to improve. The personal experiment quickly turned into something bigger: thousands of my viewers had the same pain. That's how the Chrome extension came about.
Why prompts specifically
The core problem Opten solves: every model is written differently. Kling reacts to one phrasing of motion, Sora to another, Midjourney loves cinematography jargon, Nano Banana wants short dense descriptions with no filler. There are no universal "10 tips for writing a prompt": what works for Flux produces garbage in Imagen.
I assembled 60+ skill files for specific models — Seedance (all versions), Seedream, Kling with motion control, Midjourney 7/8/niji/video, GPT Image, Flux, Nano Banana, Imagen, Luma Ray, Sora 2, Veo 3/3.1, Runway, MiniMax Hailuo, Pixverse, LTX, Wan, Qwen, Grok Imagine and others. Plus two fallback modes for when you try something rare. Each skill file is a set of rules distilled from the model's official documentation and my own generation experience.
Opten doesn't just score a prompt 0–100 and surface up to five specific issues. It also does auto-enhance — one click rewrites the prompt for the selected model. Parallel rewrite: hit it, get an improved version a second later.
What you get
Install the extension → open your favourite AI generator (Syntx, Higgsfield, Freepik, Magnific — support is widening) → write a prompt as usual → Opten scores it silently right inside the interface, without pulling you into a separate window.
What you get:
- 0–100 score against the rules of the specific model — you see immediately how strong the prompt is.
- Up to five concrete callouts with pass/fail/neutral icons. Not "try again", but "no lighting style specified, add soft daylight".
- Auto-enhance — improved prompt in one click. No "here are ten tips" — just ready text you can copy or apply with a button.
- Multimodal — Opten accounts for the reference images you already attached. It won't suggest adding something that's already in the preview.
- Auto-detected model — no need to tell it "this is Kling" by hand; Opten looks at the page URL and DOM markup.
- Privacy — your prompts and references are not stored on Opten servers. Analysis runs through Claude Haiku 4.5 behind a private Vercel proxy, pure pass-through.
- RU / EN — the interface picks up the browser language.
On pricing: install and registration are free. Pro is 199 ₽/mo auto-renewed through YooKassa, or 299 ₽ one-time without a monthly subscription. For USD payments — Paddle, around $2.99/mo or $4.99 one-time. That's five times cheaper than PromptPerfect ($9.99), and Opten works across dozens of interfaces rather than just inside its own chat.
