RIVAL: Comparing AI models, visually

Ever tried to figure out which AI model is best for a specific task? It usually involves a lot of tab-switching, copying prompts, and mentally comparing outputs. I wanted something better.

The Project

RIVAL is an open-source web app that lets you visually compare one-shot responses from different AI models (GPT-4o, Claude 3.7, Grok 3, etc.) side-by-side.

Instead of reading documentation or jumping between interfaces, you can see exactly how each model handles the same challenge—whether it's generating code, designing a website, creating SVGs, or analyzing text.

Key Features

  • Interactive Comparisons: Visual side-by-side model outputs with expandable cards
  • Challenge Categories: Organized by task type and difficulty
  • Content-Forward Design: See actual outputs without clicking through menus
  • Minimalist UX: Clean interface with subtle animations and retro-inspired details

Why I Built It

I was tired of the fragmented experience of testing AI models. Documentation tells you what models can do, but seeing is believing.

RIVAL emerged from a desire to make model comparison more visual, intuitive, and useful—both for my own projects and for anyone interested in AI capabilities.

Tech Stack

Built with modern web technologies and open-sourced for the community to use, extend, and improve.
