ChatHub lets you chat with multiple AIs side-by-side. AI Hub adds the next layer: models that react to each other, relay context, run structured plans, and connect to local models.

ChatHub does parallel chat well — but it stops there. AI Hub treats multiple AIs as a collaborating team: debate mode has AIs argue and react to each other's answers, relay mode feeds all responses as context into the next round, and plan mode runs a structured planning session then synthesizes what all AIs agreed on versus where they differed. Add local Ollama support, conflict detection, and a full prompt library — all free and open source.
