I got frustrated watching people struggle to get good results from Midjourney and ChatGPT not because the models are bad, but because prompting them well is genuinely hard and nobody teaches you how. I'd been building in the SaaS space before this and saw the same pattern: huge search demand, real user pain, and almost no tools actually built around how each model works. PromptHero is a library. Generic improvers don't know the difference between a Midjourney parameter and a ChatGPT system prompt. Nobody was building model-specific generators. So I built one. Then twelve. The approach evolved fast. I started with Midjourney, validated the search demand, then systematically expanded to ChatGPT, Gemini, Claude, Grok, and the vibe coding tools like Bolt, Lovable, Cursor and v0. Each page is purpose-built for that model's syntax and use cases, not copy-pasted with a different name swapped in. A Chrome extension came later as a second acquisition channel so users can generate prompts without leaving their workflow. Still early, still growing. Happy to answer anything about the build, the SEO strategy, or what's coming next.
