Three frontier models cross-examine each other, and one answer survives
Beginner API
What is Triall?
Triall is an AI search tool. Triall puts a question through three frontier AI models that answer independently, then critique and rank each other's work blind, with key claims checked against live web sources. Output is one surviving answer plus a SURVIVES, WEAKENED or REFUTED verdict.
Triall is a question answering service built around a simple premise: a single model cannot reliably audit its own output. Instead of asking one assistant for an answer and trusting the tone of confidence, Triall runs the question past three frontier models that work in isolation. Before any of them respond, it pulls live web sources on the topic and feeds that evidence into the pipeline, so the reasoning starts from retrievable material rather than recall alone. Each model writes its answer in its own room with no visibility into the others. That separation matters, because models that can see a first draft tend to anchor on it. Kept apart, their errors diverge, and the points where they disagree become the interesting ones. The three drafts are then stripped of authorship and sent back for a tribunal round, where every model attacks and ranks all three answers without knowing which one it wrote. Rankings are combined, and the answer that holds up best earns the right to become the final output. That draft is rewritten to withstand the sharpest criticism the tribunal raised, then its load-bearing factual claims are checked against real sources and tagged verified, contradicted or unconfirmed. The delivery is a single answer plus a verdict: SURVIVES, WEAKENED or REFUTED. The tribunal also flags answers that merely agree, hedge constantly or flatter the asker, and those flags sit next to the verdict. If the result comes back weakened, the user can order a repair and watch it go through review again. Triall sits in the same space as multi-model chat aggregators, but where those present several answers and leave the judging to you, this one performs the judging and returns a ruling. It suits researchers, analysts, writers and developers who need to know how much of an answer is likely to hold up, and it is accessible through a web interface, an MCP endpoint for Claude and ChatGPT, and a REST API for custom applications.
How do you use Triall?
1Run a free session without an account
Open the homepage and start a trial run. Three sessions are available with no signup, which is enough to see how the verdict format reads on a question you already know the answer to.2Write a hard question rather than a trivial one
Triall is built for questions where a confident wrong answer is costly. Ask something specific and checkable so the verification step has claims to work with.3Read the verdict before the answer
The result arrives as SURVIVES, WEAKENED or REFUTED. Check that first, then read the synthesis and the flags the tribunal raised about agreement or hedging.4Inspect the source checks
Load-bearing claims come back marked verified, contradicted or unconfirmed. Treat unconfirmed items as open questions rather than settled fact.5Repair a weakened answer
When the verdict comes back weakened, order a repair and watch the revised answer go through the tribunal again before relying on it.6Buy credits and connect the API
There is no subscription requirement. Purchase credits on the pricing page, then wire up the MCP endpoint or REST API to run the same pipeline from Claude, ChatGPT or your own tooling.
Pros and cons
Pros
- Blind isolation between the three models reduces the anchoring that plagues single-model reviewAI
- Every result carries an explicit verdict and source checks rather than just an answerAI
- Agreement and hedging are flagged, so sycophantic responses surface instead of hidingAI
- Weakened answers can be repaired and sent back through the tribunalAI
- Works inside Claude and ChatGPT via MCP as well as over a REST APIAI
Cons
- Three models plus verification rounds make each run slower and heavier than a single chat promptAI
- The verdict is a judgment from the same model family being tested, not an independent auditAI
- Source checks cover only load-bearing claims, so secondary assertions go unverifiedAI
- No detail is published on which three frontier models are actually usedAI
