One app, chat with every major AI model
ChatGPT · Claude · Gemini · DeepSeek · Doubao · Qwen — switch and compare any time
One model isn't enough, and switching back and forth is a pain
Different large models each have their strengths — some are great at writing code, some at long-form analysis, some sound more natural in Chinese. Paying for separate memberships, installing several apps and copy-pasting between them is exhausting. TonboAI brings the leading models into one chat box, so one account lets you switch and compare side by side any time.
Too much back-and-forth
ChatGPT in one app, Claude in a browser tab, Gemini somewhere else — asking the same question means opening half a dozen places. Now one chat box handles it all.
Separate memberships cost too much
A monthly plan for each model adds up fast at month's end, and the quotas often go unused. With TonboAI it's one balance, pay as you go, only pay for what you use.
Not sure which one to use
Ask the same question and different models answer differently. Compare them side by side and pick the reply you like best.
A dedicated AI channel at the network layer
More than a proxy — TonboAI builds an independent encrypted tunnel for every AI request at the network layer, smart-routes to the globally optimal exit node, and delivers end-to-end encrypted direct connections to ChatGPT · Claude · Gemini · Sora.
End-to-end encrypted tunnel
Every AI request travels through its own encrypted channel. Keys are generated on the client; data never touches a third-party server. Complete privacy throughout.
AI smart routing
The optimal exit node is selected in real time for each target AI platform — ChatGPT, Claude, and Gemini each get their own best path for the lowest latency.
Precise split tunneling · Domestic direct
Domestic traffic bypasses the tunnel entirely; only AI and overseas requests go through the secure channel. Full speed and full privacy without affecting everyday browsing.
