Overview
ChatHub is a unified platform that lets users chat with and compare multiple AI models side by side, including GPT, Claude, and Gemini. A single subscription gives access to 20+ models plus image generation, file analysis, and web search.
Our take
ChatHub lets you query several AI models side by side in one interface, which is genuinely useful for comparing outputs and for avoiding lock-in to a single provider. It is a convenience layer, so what you get depends on the models underneath and on whether you bring your own API keys or use the included access.
Worth it if
People who want to compare model responses directly rather than switching between several tabs.
Look elsewhere if
Anyone who has settled on one model — the comparison layer adds cost without adding capability.

❓ Frequently Asked Questions
Is side-by-side comparison actually useful?
More than expected, for a specific reason: models differ noticeably by task, and the differences are invisible unless you see the answers together. It is particularly worthwhile when choosing which model to standardise on for a repeated job. For everyday use, it mostly adds noise once you have decided.
Should I use my own API keys or the bundled plan?
Your own keys usually cost less at low volume and give you the provider's own data terms, which matter if you handle anything confidential. A bundled subscription is simpler and predictable. The consideration people miss is data handling — a middle layer sees your prompts, so check what it retains either way.
