Run the Same Prompt Across Multiple AI Models
MultiChats lets you run the same prompt across multiple AI models. Branch a conversation, keep the prompt fixed, and switch the model on each branch to send it to GPT-5, Claude, Gemini, and others. You compare every model's output in one app under a single subscription.

Test once, see every answer
Prompt engineering and model selection both improve when you can see how different models handle the exact same input. MultiChats makes that a built-in workflow rather than a copy-paste chore across tabs.
How branching keeps it clean
Fork your conversation into branches that share the same prompt and context. Set each branch to a different model, then read the responses together. Nothing about your original prompt changes, so the only variable is the model.
One plan, every model
Running a prompt through five models is just five messages from your unified MultiChats pool ($20.99/mo Pro), with no separate per-provider subscriptions or API keys to manage.
How it works
- 1Write your prompt once. Send your prompt to the first model in a MultiChats conversation.
- 2Branch the chat. Fork the conversation so each branch starts from the same prompt and context.
- 3Change the model per branch. Assign GPT-5, Claude, Gemini, or any other model to each branch.
- 4Compare and keep the best. Read the answers side by side and continue with whichever model won.
