One conversation. Every AI model.
Testudo brings GPT, Claude, and Gemini into a single thread. Stop switching tabs. Stop losing context.
Currently in development. Early access invites go out soon.
THE PROBLEM
This is what using AI looks like today
Three subscriptions, three tabs
You pay for ChatGPT, Claude, and Gemini separately — each in its own tab.
Context lost on every switch
Moving from one model to another means copy-pasting the whole conversation.
You never know which one's actually better
Instead of comparing in one place, you're asking the same question three times.
THE SOLUTION
One thread. Three models. Nothing lost.
Switch models instantly
Move from GPT to Claude mid-conversation — context comes with you.
Ask all at once
Send one question to all three models, compare answers side by side.
Branch and merge
Try different answers, pick the best, or merge them into one.
WHY TESTUDO
The market has AI tools. Here's our edge.
Comparing is a moment. Branching is a structure.
Most tools show you multiple answers once, then move on. We turn every comparison into a real branch — go back, try another model, merge two answers into one. Nothing is ever lost.
Your chats are yours.
Stored locally, not in someone else's cloud. Privacy isn't an add-on — it's the default.
A real app, not another tab.
Built natively for Mac and Windows — faster, less cluttered, actually part of your system.
One conversation, not a pool of chats.
Most tools give you access to many models, each stuck in its own isolated chat. We keep everything in one conversation: switch models, but never lose the thread.
In 52 BC, Roman legionaries faced a hail of arrows outside the walls of Alesia. They didn't retreat. They locked shields — above, beside, and in front — and kept moving forward. No single soldier's shield was enough. But together, they were impenetrable.
That formation was called the testudo. Three models. One formation. Every answer covered.
