How to Use Multiple AI Models at Once (Without 6 Browser Tabs)

You open ChatGPT for a draft. Then Claude, because it's better at tightening long prose. Then Perplexity, because you need a real source. Then Gemini, because the document is too long for the others. Four tabs, four logins, and you've pasted the same context four times.

If you use AI seriously, you already know no single model is best at everything. The problem was never picking the right model — it's that using more than one is a logistical mess. Separate tabs, separate bills, and context that doesn't follow you from one to the next.

This guide shows you how to use multiple AI models at once the practical way: in a single conversation, with one login, switching models as the task changes. No tab circus required.

Why You End Up With Six AI Tabs Open

Nobody plans to run six AI tools. It happens one task at a time.

You start with one model for everything. Then you notice it's weak somewhere — maybe it invents sources, or its writing all sounds the same, or it chokes on a long PDF. So you add a second tool for that job. A few weeks later you add a third for research, a fourth for polishing drafts. Each one is genuinely better at its specialty:

• One model drafts fast but its prose is generic.
• Another follows instructions to the letter and writes in a cleaner, more natural voice.
• A research engine cites real, live sources instead of guessing.
• A long-context model swallows an entire contract or report without losing the thread.

Every addition is rational. The pile of tabs that results is not. (For a full breakdown of which model actually wins at which task, see Stop Using Just One AI Model.)

The Hidden Cost of Switching Between AI Tools

The pain of a multi-tool setup isn't the models — it's the switching. Three costs add up quietly:

1. Lost context. Every time you move to a new tool, you start from zero. You re-paste the brief, the constraints, the half-finished draft. The new model has no idea what the last one just did.
2. Repeated prompts. That re-pasting isn't free. You're rewriting the same setup over and over, and any detail you forget to carry across degrades the answer.
3. Multiple bills. ChatGPT, Claude, Gemini, Perplexity, and Grok each charge $20–$30/month for their paid tiers. Stack five or six and you're paying around $120/month — often for tools you only open a few times a week.

The fix isn't to give up and crawl back to one model. It's to keep the multi-model approach and delete the switching tax.

How to Use Multiple AI Models in One Place (Step by Step)

The cleanest way to run several models is to stop treating them as separate apps and put them in one workspace, where they share a single conversation and a single subscription. Here's the workflow.

1. Pick the right model for each task

Instead of opening a different app, you open a model picker inside the same chat and choose the right engine for the job at hand — a generalist for drafting, a sharp reasoner for tricky problems, a research model for sourced facts, a long-context model for big documents.

In izzedo chat, every leading model — GPT, Claude, Gemini, Grok, Perplexity Sonar, DeepSeek, Qwen, Llama, plus image models — sits in one dropdown. Choosing a model is a single click, not a new tab and a new login.

Here's a quick cheat sheet for which model to reach for:

What you're doing	Reach for	Why
First drafts & brainstorming	ChatGPT	A fast, versatile generalist for getting ideas down
Polishing & long-form editing	Claude	Follows detailed instructions and writes in a clean, natural voice
Research with real sources	Perplexity Sonar	Searches the live web and cites where each fact came from
Hard reasoning & math	Gemini or Grok	Built for careful, step-by-step problem-solving
Very long documents	Gemini	Handles huge amounts of context in a single pass
Images	Image models	Generate and edit visuals without leaving the chat

None of these are locked in — the whole point is that you can pick the best model for each step and change your mind a sentence later.

2. Switch models mid-conversation without losing context

This is the part separate tabs can't do. Because every model shares the same thread, you can switch models in the middle of a conversation and the context comes with you.

Draft with one model, then switch to another to sharpen the tone — in the same thread, with no copy-paste. The second model sees everything the first one wrote, so it builds on the work instead of restarting it. Ask one model for a fast answer, then hand the exact same conversation to a stronger reasoning model when you hit something hard.

Here's a real exchange from the screenshot above. I asked ChatGPT for a one-sentence welcome tagline for a bookstore and got a solid one: "A cozy corner for curious readers, warm conversations, and stories that feel like home." I wanted punchier options, so I switched to Claude in the same thread — without re-pasting the brief. Because Claude already had the full context, it built straight on the idea instead of starting over: "Where every book feels like a hug and every reader feels like a regular." Two models, one conversation, zero copied-and-pasted setup.

For a hands-on version of this — sending one prompt to several models and picking the best reply in under a minute — see How to Finish Any Task Faster by Asking 3 AI Models Instead of 1.

3. Ask several models the same question at once

For anything high-stakes — a fact you'll publish, a number you'll act on, a recommendation you'll put your name on — don't trust one model's word. Ask the same question to several models at the same time and compare their answers side by side.

When the answers agree, you can move on with confidence. When they disagree, you've just caught something worth a second look — and the disagreement itself is the signal. izzedo's Multiple Model Opinions feature is built for exactly this: same question, multiple models, side by side, in one place.

When Using Multiple Models Actually Matters

You don't need three models for a grocery list. Multi-model pays off most in three situations:

• Research you'll rely on. Gather sourced facts with a web-research model like Perplexity Sonar, then hand the findings to a strong writer to synthesize. Sources stay attached; the synthesis stays grounded.
• Writing that has to land. Draft fast with one model, then pass it to a more precise editor model to tighten the structure and voice. The second model catches the weak transitions and filler the first one glossed over.
• Important decisions and facts. Anything you'll publish, send to a client, or base a decision on deserves a second opinion. Cross-checking across two models is the fastest hallucination filter there is.

In every case the workflow is the same: the right model for each step, all inside one conversation. (Want exact, copy-pasteable workflows? 4 Tasks That Take 3 Hours With One AI — and 20 Minutes With Three walks through four of them.)

One Workspace, Every Model

Here's the math that makes this easy. Running ChatGPT, Claude, Gemini, Perplexity, Grok, and DeepSeek as separate subscriptions costs around $120/month — six bills, six logins, zero shared context.

This is the problem we built izzedo chat to solve. Every model in one conversation, one login, one bill — starting at $6/month, with a free plan that needs no credit card. Switch models mid-thread, ask several at once, and keep your projects and context in one place instead of scattered across a browser full of tabs.

See the pricing plans to compare it against the stack of subscriptions you're paying for now.

The goal was never to find the one perfect AI. It's to use the best one for each task — without the six tabs, six logins, and six invoices that used to come with it.
