Our take: Choose Fixy if you want one chat that puts GPT, Claude, Gemini and Grok side by side and synthesizes a final answer, with plans from $1.99 per month.
Main limitation: Pricing could only be read from the vendor llms.txt file, since the pricing page is client-rendered.

What is Fixy, and how does it work?
Fixy is a browser-based chat that sends one question to GPT, Claude, Gemini and Grok, shows where they agree or disagree, and produces a single final answer.
The same account covers Fixy Code, a multi-agent terminal tool, and Fixy Works, a Mac desktop app for AI Workers. Users can also connect their own provider API keys.

Fixy features and their limits
Feature overview on the official site. fixy.ai, captured Oct 2, 2026
Multi-model group chat
Sends your prompt to several models at once and shows them together. Researchers can see several models answer the same prompt at once instead of pasting it into each service.
Access: Not statedLimit: Each model uses credits, so asking several models costs more than asking one.source (opens in a new tab)
Final Answer card
Summarizes agreement and disagreement into one answer. Readers get one summary of where the models agree and disagree instead of reading every reply.
Access: Not statedLimit: The card is based on the model outputs, so it inherits their errors.source (opens in a new tab)
Debate, Consensus and Red Room modes
Runs structured argument formats. Decision makers can have models argue a proposal, reach a consensus or attack it instead of getting a single opinion.
Access: Not statedLimit: Which plans include each mode was not readable in the official pages we could read.source (opens in a new tab)
Shared rooms for humans and AI agents
