LLM Jealousy Engine — Multi-AI Competitive Prompting Tool
A SaaS tool that automatically sends the same prompt to multiple LLMs, then feeds each model a rival's output to trigger competitive improvement cycles — delivering the best result without manual tab-switching.

Greg's core hack is manually opening ChatGPT, Grok, Claude, and Gemini simultaneously, submitting the same prompt, then telling each LLM that a competitor scored a 9/10 while it only scored 5/10 — forcing it to try harder. The result is noticeably higher-quality output. Right now this is a tedious manual workflow involving multiple browser tabs and copy-pasting.
The business opportunity is to productize this into a single-interface tool: submit one prompt, get parallel responses from all major LLMs, then auto-run a second competitive-feedback round where each model sees the best rival response and is challenged to beat it. The tool could surface the winning output, let users blend elements, and even track which LLM wins most often for specific task types (copywriting, code, strategy, etc.). Monetization via subscription tiers based on API call volume.

03 THE VERDICT
This is a genuine workflow gap that millions of AI power users experience daily — the manual version works and Greg demonstrates it live, which is strong validation. No existing tool has productized the iterative rivalry mechanic, making differentiation clear and defensible for at least 12-18 months. API costs are manageable at scale with usage-based pricing, and the concept is inherently viral (people love sharing prompting hacks). The main risk is that OpenAI or Anthropic builds a native comparison feature, but even then a neutral multi-vendor tool has lasting appeal.
