Best ChatHub Alternatives 2026 — Multi-Model AI Apps Beyond Extensions
TL;DR: Perspective AI is the best ChatHub alternative for a full multi-model app experience. Poe is best for model variety. Merlin AI is the best alternative browser extension with deeper website integration.
ChatHub is a popular Chrome extension that shows AI model responses side by side — send one prompt and compare GPT-5.2, Claude, and Gemini simultaneously. At $6.99/mo, it's affordable for quick model comparisons. But it's limited to being a browser extension: no mobile app, no AI tool marketplace, no deep features like Canvas or Projects, and no mid-conversation model switching.
We tested 8 ChatHub alternatives for users who want multi-model AI access as a standalone app, on mobile, or with deeper features than a browser extension can offer.
