For people tired of switching tabs

Consensus first, decide with more confidence

Send one question to multiple AI services. ChatDuel compresses repetitive copy and paste into one action, then helps you collect shared recommendations, repeated risks, and real disagreements.

High user trust

No API key, no handing privacy to another platform

Many aggregator tools ask users to buy credits or paste their own API key into a third-party service. That raises privacy concerns, account worries, extra costs, and a hard-to-estimate API bill.

ChatDuel reuses the official web pages you already log into. Free accounts and paid subscriptions keep working the same way; ChatDuel simply puts those pages in one workspace so you can ask, compare, and summarize faster.

No API key

No need to share keys with a third party or learn tokens, credits, and model pricing.

No extra API bill

Keep using your own web accounts instead of opening another usage-based billing layer.

No moving your chats away

History stays local, while the website only provides the necessary privacy policy entry.

Compare like you already do, but without the busywork

Different models shine in different tasks: planning, coding, research, shopping, writing, and review. Comparing multiple opinions is natural. ChatDuel makes that habit much less tedious.

Shopping

Find shared picks

Products recommended by several AIs are usually worth comparing first; majority picks make a better shortlist.

Planning

Collect repeated feedback

When the same risk is raised more than once, treat it as important. Fix those points before style suggestions.

Long answers

Compress to decisions

When answers are too long, start from shared views, main disagreements, and the next action instead of reading every paragraph.

Uncertainty

Reduce single-model bias

One AI can miss an angle. Multiple answers make it easier to spot the safer conclusion.

No API key, no API usage guessing

ChatDuel is built for everyday AI users. You keep using the official web accounts you already have, whether free or subscribed, without applying for API keys or calculating tokens, balances, and usage fees.

That is the biggest difference from most API aggregators: it does not ask you to buy another pool of credits. It makes the AI web pages you already use easier to compare.

More than parallel sending

An AI decision compiler

The value is not only sending the same question everywhere. It is compiling multiple answers into something usable: shared recommendations, disagreements, risk lists, and what to change next.

Summarize

Collect the opinions mentioned by multiple AIs and start from the steadiest parts.

Disagree

Separate the places where answers truly conflict so long text does not hide them.

Cross-review

Let one AI review another AI's answer to inspect a plan, add angles, and find gaps.

Fewer claims, faster judgment

The page keeps only the actions users can understand immediately.

One input, multiple sends

Send the same question to several AIs, or send to one selected service.

One-click consensus

Organize shared recommendations, risks, and viewpoints first.

One-click disagreement

Pull out the places where answers actually differ.
