The Multi AI Chat App That Compares Every Answer

Ask once. Read every AI side by side.

Qorpus is an all-in-one AI app for multi chat: it sends one question to ChatGPT, Claude, Gemini, Perplexity and Grok at the same time.

Every answer arrives in one screen, next to the others. You read them together instead of asking five apps the same thing.

It runs on Android and in your desktop browser, and it is free to install.

One AI answer is one point of view

A single model gives you one framing of the problem. It sounds finished, which is exactly what makes it easy to accept.

The better detail sits elsewhere

One model catches the exception the others skip. You only find it if the answers are in front of you at the same time.

You anchor on whichever answer came first

The first reply sets your thinking before you have anything to weigh it against. Reading in parallel removes that pull.

High stakes need a second opinion

For a contract clause, a dosage, a tax position or code about to ship, one confident answer is not enough to act on.

Why compare AI models on your phone

Phone questions get asked away from your desk, with less time to verify. That is exactly when you want to compare AI models, not trust one.

Catch what one model left out

Send the question once and see the parts only one model thought to mention. Nothing gets retyped between apps.

See the assumptions each model made

Given identical constraints, different models optimise for different things. The gap between them tells you what is really being traded.

Check the claims that would cost you

When two models disagree on a fact, you have found the thing to verify. Agreement is not proof, but disagreement is a flag.

Stop switching between five apps

No copying a prompt into one app, then another, then trying to hold five replies in your head. One question, one screen.

How the app works

Four steps, and the app handles the repetition so you do not have to.

Ask once

Type your question one time. Qorpus sends it to every model you picked, unedited, so the comparison stays fair.

Compare every AI

Answers come back into one screen. Swipe between them on a phone, or read them in columns on desktop.

Sort agreement from contradiction

Where the models say the same thing, you can move. Where they split, you have a shortlist of what to check.

Follow up with the best one

Carry on the thread with whichever model gave you the strongest start, without retyping any of the context.

Use the AI accounts you already pay for

Qorpus signs in with your own AI accounts. There is no API key to generate and no developer console to open.

That means you get the model versions you already pay for, at the quality you pay for, because nothing is resold in between.

There is no second subscription stacked on top of the ones you hold. If you already pay for ChatGPT or Claude, that is what runs.

Built as an Android AI assistant

The Android app runs the same comparison as the desktop browser, sized for a phone. Answers stack so you swipe between models.

Pick up the thread with whichever model gave you the better start, without losing the other answers.

Install it free from Google Play. It takes one tap and your existing AI logins.

Which AI models Qorpus compares

Qorpus works with ChatGPT, Claude, Gemini, Perplexity and Grok.

You choose which models a question goes to each time. A quick lookup does not need all five. A decision that matters can have them.

A Poe, ChatHub and Multi Chats alternative with no API key

People arrive at Qorpus from Poe, ChatHub and Multi Chats, and the difference is the account model.

Those tools generally route you through an API key or resell model access inside their own subscription.

Qorpus runs on the AI logins you already hold, and it is built around putting answers next to each other rather than storing a chat history. Qorpus is neither a one-subscription aggregator nor a bring-your-own-API-key tool. It runs on the AI logins you already have, with no API key and no extra subscription.

Questions worth comparing

Research where you need a source, not a summary. Writing where tone matters more than word count.

Code where there is more than one sensible approach. Plans where a hard constraint forces a trade-off.
