Why Multio — the all-in-one AI chat
An all-in-one AI chat app gives you every major AI model in a single interface. Multio unifies 100+ AI models — 10+ free plus GPT-5, Claude, Gemini, Grok and more.
Every major model, one app
Why a single app for every AI
Paying separate subscriptions for ChatGPT, Claude, and Gemini is expensive and fragments your history. An all-in-one AI chat lets you switch models mid-chat, keep files attached across sessions, and pick the model that actually fits the task.
Compared to alternatives
The all-in-one AI chat category includes AI Fiesta, Magai, AiZolo, MultipleChat, Poe, T3 Chat, ChatLLM, TypingMind and Msty. Each takes a different approach. Read our honest head-to-head comparisons on the Multio blog.
