Many users search for one subscription that includes ChatGPT, Claude and Gemini. This page explains what that usually means and where the tradeoffs are.
Comparison matrix
Use the table as a buying checklist. Verify live prices, plan names and model access on official provider pages before paying.
| Need | Best first pick | Why it fits | What to verify |
|---|---|---|---|
| Need one place for all models | MultipleChat AI | Use ChatGPT-style, Claude-style and Gemini-style models in one workspace. | Check exact model list. |
| Need native ChatGPT features | ChatGPT subscription | Voice, custom GPTs and OpenAI-native features may be better in ChatGPT. | Do not cancel if those matter. |
| Need Claude long writing | Claude plan | Claude can be strongest for long prose and document reasoning. | Compare caps. |
| Need Google ecosystem | Gemini / Google AI plans | Useful for Gmail, Docs, Drive and storage bundles. | Value depends on Google usage. |
| Need normal chat plus options | MultipleChat AI | Use one AI normally for most tasks, then switch models, compare outputs or use AI Collaboration when the work gets harder. | This is where full workspaces beat simple comparators. |
| Need cheapest access | Compare bundle vs separate plans | A bundle can be cheaper than multiple native subscriptions. | Only if limits fit your use. |
Practical guidance
They want one bill, one login and access to several leading models without tab switching.
The bundle may not include every native feature, may have different caps, or may not expose the newest model immediately.
Use the bundle for daily multi-model work. Keep one native subscription only if a native feature is essential.
FAQ
Yes, through any of the bundles here — but check the model class. Bundles reach these providers through commercial APIs, so what you get is whichever tier the bundle pays for. MultipleChat, for instance, includes a Flash-class Gemini rather than the Pro-class model in a Google AI Pro plan.
Much cheaper on paper. ChatGPT Plus, Claude Pro and Google AI Pro together cost about $60 a month, against $15 to $20 for most bundles. The catch is that three native plans give you three sets of published limits and full-size models, while a bundle gives you one shared cap and, often, undisclosed model sizes.
Everything that is not exposed through the API. That means Claude Code and Cowork, ChatGPT's Codex and Sora, Copilot inside Word and Excel, Perplexity's Comet browser, and native voice modes. If any of those is part of your workflow, the bundle supplements your native plan rather than replacing it.
ChatHub lists the current generation — GPT-6 Astra, Claude Opus 5 and Sonnet 5 — on both paid tiers with published query caps. Merlin's own site advertises nothing newer than Claude 3.7 Sonnet, which is worth verifying in the picker before paying.
