How we checked

We read each app's own pricing, home and help pages on September 28, 2026 and quote what they say, with a link. We didn't subscribe to the apps or score their answers, so nothing here says one app's models answer better than another's. Prices change: a quote is what the page said that day, and this page leaves search if it isn't checked again within 45 days.

We make llmwise. Its row comes from its own plans, and it sits where the alphabet puts it. Where another app says it gives more messages on a model than llmwise does, the table says so.

Multi-model chat apps: questions

What app lets me use Claude, GPT and Gemini in one chat on one subscription?

ChatHub, llmwise, Magai, Mammouth, Monica, MultiChats, Overchat, Poe, Quad Chat, and Zemith each sell a plan with all three; TypingMind is bought once, and you pay the model companies per use; T3 Chat shows its plans only after sign-in. The table gives each one's price, counts and free tier, from its own pages on September 28, 2026.

Which of these apps say how many messages you get?

ChatHub: 1,500 a month on its bigger models (Pro), llmwise: a count on every model: on Pro, from up to 31 a month on the biggest to up to 250, and 60 a day on the everyday models, Monica: 200 a month on its bigger models (Pro), MultiChats: 1,500 a month (Pro); bigger models use more per reply, and Quad Chat: an estimate: about 800 Claude Sonnet 5 messages a month (Pro). Magai, Mammouth, Overchat, Poe, and Zemith measure use in points, dollars' worth or their own units, with no message count.

Can I switch between models in the middle of a conversation?

llmwise, Magai, MultiChats, Quad Chat, TypingMind, and Zemith say you can switch models in the same conversation. ChatHub and Monica put several models' answers side by side instead.

Which of these apps can I try free?

ChatHub, llmwise, Monica, MultiChats, Overchat, Poe, Quad Chat, TypingMind, and Zemith have a free tier, each with its own limits (the table says which). Magai and Mammouth list no free plan, and we couldn't read T3 Chat's.

Is one app cheaper than paying for each AI separately?

ChatGPT Plus $20, Claude Pro $20, Google AI Pro $19.99, and SuperGrok $30: $89.99 a month together, at the prices their pages gave. Every entry plan we could read here costs less than that; before you switch, check what the plan's count covers on the biggest models.

Did you test these apps?

No. We read each app's own pricing, home and help pages on September 28, 2026 and quote them with links; we didn't subscribe to them or score their answers. We make llmwise: its row comes from its own plans, and it's listed alphabetically, not first.
