How to Get Claude, GPT and Gemini in One Chat Window

If you've ever wanted to ask GPT and Claude the same question back to back — without opening two tabs, logging into two accounts, and re-typing your prompt — you've run into the actual problem with today's AI landscape. The models are commodity-adjacent; the login walls between them are not.

Here are the three ways people actually solve this, ranked by how well they work.

Option 1: Keep multiple tabs open and copy-paste between them

This is what most people default to. It works, technically. In practice it means your context lives in your clipboard: you copy the question into ChatGPT, copy the answer out, paste it into Claude to compare, and now you're maintaining conversation history in your head instead of in either app. For a one-off comparison this is tolerable. For anything you do daily, it's a tax you pay every single time.

Option 2: Use each provider's official app and switch by habit

Some people just use whichever app they happened to open — ChatGPT for most things, Claude when they remember it's better at code, Gemini when it's already open because of Google Workspace. This avoids copy-paste but means you're never actually comparing outputs, just picking based on whichever tab has focus. You lose the main benefit of having access to multiple models, which is being able to check one against another.

Option 3: A single app with model switching built in

The direct fix is a chat interface where the model is a dropdown, not a login. You keep one conversation thread, and you can send the next message to GPT, Claude, Gemini, DeepSeek, or Kimi without losing the context that came before. This is the actual unlock — not "having access to five models" (free tiers already give you that), but keeping them in the same thread so switching costs you a click instead of a context-reset.

AIWITH.CHAT is built specifically for this — one login, one chat window, model switching mid-conversation. You ask GPT-5.6 to draft something, then switch to Claude Fable 5 to review it, then to Gemini to check a long document reference, all in the same thread, all under $10/month instead of three separate $20/month subscriptions.

What this actually changes day to day

The value isn't abstract. Concretely, it means:

You stop defaulting to "whichever app I already have open" and start actually using the model best suited to the task in front of you.
Cross-checking a factual or numerical answer against a second model takes one click, not a five-minute context rebuild — so you actually do it, instead of skipping it because it's annoying.
You're not paying for three subscriptions to keep three logins "warm" in case you need them.

If you're currently juggling tabs or picking a model out of habit rather than fit, this is the specific friction that's costing you the most.
