AI Model Aggregator
Prompt, Compare, and Unify Multiple AI Models in One Interface
Chat with GPT, Claude, Gemini, and Grok simultaneously, let them refine and combine each other’s answers, and pay only for usage with your own API keys.
The Problem
AI is fragmented and expensive.
Expensive subscriptions
$20/month per provider. ChatGPT Plus, Claude Pro, Gemini Advanced - costs stack up fast.
No way to compare
You can't see how different models answer the same question. Switching tabs wastes time.
Models can't collaborate
Each model works in isolation. No way to share insights or build on each other's strengths.
The Solution
What CrossChat does
Pay per token, not per month
Bring your own API keys. Access every model without subscriptions. Most users spend less than $5/month on actual usage.
Side-by-side comparison
One prompt, multiple models. Responses stream in simultaneously. See which model gives you the best answer.
Roundtable discussions
Models read each other's responses. Claude critiques GPT. Gemini builds on their insights. Better answers through collaboration.
Unified output
Pick a model to review all responses and combine the best elements into one definitive answer.
