Cover image for MixerAI is a Chrome extension

MixerAI is a Chrome extension that consolidates ChatGPT, Claude, Gemini, and Perplexity into a single dashboard. Most heavy AI users are paying for 2-4 subscriptions and constantly switching tabs to use the right model for the right task. MixerAI fixes that. Features: Unified connection status for all major AI services in one panel Smart subscription tracking so you can see which plans you're on across providers Plan recommendation engine that suggests Free vs Pro vs Max tiers based on your usage patterns Single task input that routes your prompt to the best-suited AI for the job Built with TypeScript, React, Chrome Extensions API, Tailwind, and integrations with OpenAI, Anthropic, Google, and Perplexity APIs. This project came from frustration with my own AI tool sprawl: four tabs open, two paid subscriptions I wasn't fully using, and no system for deciding which model to ask. MixerAI is the tool I built to solve that for myself, and now I'm shipping it for others.
