Talk to ChatGPT, Claude or Gemini. Then ask all six.
Type a slash command to ask one model directly. When the answer matters, check it with six AIs and see where they disagree.

This is on top of your normal messages and six-AI checks. Each model has its own counter.
Three ways to ask
One model
Use a slash command to talk to ChatGPT, Claude, Gemini and the others, one at a time.
Two models
Type /duel and your question to open Cove Fight with two AIs. It needs a Pro plan on the web.
Six models
Turn on the six-AI check to compare them and see the disagreements.
What to know
- It is a limited allowance, not an unlimited chat with each model
- A slash command gives one model's answer, not a consensus
- Web only for now
- Answers from slash commands are not saved to your history yet
Good to know
Is this the same as using ChatGPT or Claude directly?
No. You get a limited weekly allowance per model, and the versions depend on your plan. For unlimited use of one model, use that model's own app.
Why would I ask several models instead of one?
Models can answer differently on the same question. Seeing where they agree and disagree helps you decide how much to trust an answer.
Do the slash commands use my normal quota?
No. They have their own weekly allowance per model, in addition to your messages and six-AI checks.
Can I choose which two models duel?
On the web, /duel opens Cove Fight with the first two providers active in your settings. You can adjust the models there.
Ask one. Then check with all six.
Start with a model you know, then see what the others think.
