The doubt is marked in the answer.

One answer, read top to bottom. Where the models pull apart, the sentence itself carries the mark, so you never have to read a second document to know what to trust.

68 Agreement on the core · Disputed: where the Amazon starts Minor details, 6 models compared Analysis by Gemini independent of the consensus engine

Consensus Answer

The Nile is the conventional longest river, but the Amazon has a credible claim.

By convention and in most references the Nile leads at about 6,650 km Whether the Amazon overtakes it depends on where its mouth is drawn: counting the Pará estuary adds several hundred kilometres, and not every survey accepts that boundary.

  • The Amazon is unambiguously the largest river by discharge
  • The disputed 2007 expedition puts the Amazon at 6,992 km.

A careful answer names both rivers and the measurement dispute instead of hiding it inside one confident number.

Marked passages are checked key claims. Unmarked text was not compared individually.

Contradiction · minor detail Is the Nile definitively the longest river?
ChatGPT, Mistral, DeepSeek
The Nile is the settled answer at ~6,650 km.
the Nile is traditionally listed as the longest river at about 6,650 km
Claude, Gemini, Grok
The 2007 Amazon survey is a credible challenger.
if the Pará estuary is counted, the Amazon may exceed 7,000 km
Worth verifying: check whether the source counts the Pará estuary as part of the Amazon.

The same lens on other questions

“Is nuclear power a low-carbon energy source?”

94 High agreement no contradictions found, 6 models compared Analysis by Claude independent of the consensus engine

Consensus Answer

Yes. Its lifecycle emissions are on par with wind.

All six models put nuclear power at roughly 10–15 g CO₂-eq per kWh over its full lifecycle, far below coal and gas. The open questions they name are cost and construction time, not carbon.

Nothing is underlined: no passage in this answer is disputed.

No substantive contradictions found across the 6 answers.
Agreement is a good signal, but not a guarantee of correctness.

“Which programming language should I learn first?”

84 High agreement different emphasis on how much the goal decides, no contradictions, 6 models compared Analysis by OpenAI independent of the consensus engine

Consensus Answer

Python is the default first language.

Every model recommends Python for its readable syntax and broad use in data, automation and scripting How much the choice should follow your goal is where they set different priorities: for the web, JavaScript gets you to something running sooner.

Marked passages are checked key claims. Unmarked text was not compared individually.

Different emphasis How much should the first language depend on your goal?
ChatGPT, Gemini, DeepSeek
Start with Python regardless of the goal; switching later is cheap.
Python's simplicity lets the fundamentals stick before you specialise
Claude, Mistral, Grok
Pick by destination: JavaScript if you want to ship something visible early.
if you want to build for the web, JavaScript gets you to a running product fastest

“Can I take ibuprofen while on blood thinners?”

41 Agreement on the core · Disputed: an occasional dose 1 critical, 6 models compared Analysis by Mistral independent of the consensus engine

Consensus Answer

Avoid the combination unless a doctor approves it.

All models agree that ibuprofen raises bleeding risk on anticoagulants and most name paracetamol as the safer default Whether a single occasional dose is still acceptable is genuinely disputed, because the sources weigh the size of the added bleeding risk differently.

Marked passages are checked key claims. Unmarked text was not compared individually.

See all differences
Contradiction · critical Is an occasional ibuprofen dose acceptable?
ChatGPT, Claude, Gemini, DeepSeek
No. Avoid NSAIDs entirely unless a doctor explicitly approves.
even single doses can meaningfully increase bleeding risk
Mistral, Grok
A one-off low dose is usually tolerated.
occasional use is generally considered low risk for most patients
Worth verifying: this is a medical decision. Confirm with a doctor or pharmacist before combining the two.

Why consens.io

Built for decisions that need a second view.

Compare

Original answers stay visible

Read each model response side by side before the consensus layer summarizes it.

Verify

Disagreement is marked in place

Where the models pull apart, the sentence itself carries the mark, instead of the doubt being smoothed into one confident answer.

Control

You choose the models

Select providers, switch reasoning modes, and decide which outputs count toward consensus.

Model coverage

One workspace for leading AI providers.

Direct comparison across major model families, so every answer can be checked against independent alternatives.

What it costs

Free while I'm testing it.

consens.io is a one-person project and still very much a test. Every question you send calls six model providers at once, and that bill lands on me. That's the only reason there are limits at all.

Today

Nothing to buy right now

No checkout, no price, no waiting list. Where something is switched off, it's one of the expensive runs, and those I enable per account rather than for everyone, because they cost a multiple of a normal one.

The limits

The cap is what I can afford

Your remaining runs are shown in the app, and that number moves with what the month allows. You can also put your own provider API keys into the settings; then my limits stop applying and the costs are yours.

Later

If enough of you want it, it'll come

There's no membership today and I'm not collecting sign-ups for one. But if people keep telling me they want the expensive runs regularly, that's how I'd make it possible. Write to me either way at contact@consens.io, and have fun with it :)
