ChatHub made side-by-side AI comparison popular as a browser extension. ByteChat takes the idea further: a full web chatroom where every model shares one conversation — they answer together, chain their work, and a judge can settle disagreements with one consensus verdict.

ChatHub-style tools show several models in parallel panes: same prompt in, separate transcripts out. Useful — but each model is alone in its pane, blind to the others. ByteChat puts the models in a shared conversation: every bot sees the same context, you can ask one model to react to another’s answer, chain them in sequence, or run a Consensus round where a judge model compares all the answers and returns one verdict with a confidence score.
