TRU8

Context, not verdicts.

Paste a claim or a question. Tru8 breaks it into its checkable parts, gathers evidence from published sources, and returns a signed, organised evidence record.

01Inside a check

The summary, then the lenses.

Every check opens on a plain-English summary of what was found. Behind it, the same evidence arranged six ways. Click any screen to look closer.

The Summary
Summary

The whole record, at a glance.

What was examined, how the evidence stacks up on each side, where the sourcing runs thin, and what's missing — before you open a single source.

Lens 01 / 02
Evidence

Every source classified.

Tier × type heatmap and ledger. Filter, sort, browse. Receipts for everything excluded — no hidden curation.

Lens 02 / 02
Map

The shape of the conversation.

A citation cascade. See where sources agree, where they diverge, and which are just echoing the same original.

02The Record

What comes back.

A structured evidence record, every time: what supports each part of the claim, what challenges it, what’s missing, and what was set aside and why.

Record — what every check returnsclaimMap · _meta · _manifest
01

Element decomposition

Each claim broken into the 1–5 checkable parts that can actually be examined.

02

Supports / challenges / context

Every source mapped to the element it bears on, with a one-line reason — for, against, or framing.

03

Tier × type classification

Primary / reporting / commentary, across data, official, news, analysis, opinion and academic. Classified, never scored.

04

Echo detection

Sources that merely repeat one original are grouped — not counted as independent corroboration.

05

Gaps, named

What the record could not establish, stated as a finding — not hidden behind a score.

06

Exclusion receipts

Every source set aside carries a reason. No silent curation.

03Edges

An honest record has edges.

Bounded by what's public.

Evidence comes from external published sources — official data, research, legislation, and reporting — not private records, leaks, or primary fieldwork.

Best on a focused set of claims.

Depth per claim beats breadth. A handful of claims gets the fullest record; very long inputs are decomposed and ranked.

A snapshot in time.

The record reflects what was retrievable when you ran it. Re-running later can surface sources that did not exist before.

Under a minute — not instant.

A check runs a live search and reads every source it keeps, so it takes tens of seconds rather than milliseconds. You get a permanent link to the record when it is done.

04For developers

The same record,
structured for agents.

Everything above ships as JSON — one call, a signed evidence landscape your agent can act on. Your agent decides what matters.

05Common questions

What Tru8 does — and what it deliberately does not.

What is Tru8?
Tru8 is evidence research infrastructure. You submit a claim or a question, and Tru8 decomposes it into checkable elements, retrieves evidence from published sources, and organises the results into a structured evidence landscape — what supports each element, what challenges it, and what is missing. Submit an article and Tru8 extracts its claims for you to choose from. We organise; you decide.
How long does a check take?
Under a minute. Tru8 runs a live search and reads every source it keeps, so a check takes tens of seconds rather than milliseconds — and you get a permanent link to the record when it is done.
How is Tru8 different from a fact-checker?
A fact-checker hands you a rating — true, false, misleading. Tru8 hands you the organised evidence and its provenance, and leaves the judgement to you. You see every source, how it relates to the claim, and what could not be found, so you can show your working.
Who is Tru8 for?
Researchers, journalists, analysts and developers who need to show their working — people who would rather present an organised evidence trail than ask others to trust a single score.
What sources does Tru8 search?
The open web, plus specialist APIs across government, legislation, academic literature, economic data, news and archives — for example GOV.UK, Hansard, FRED, Semantic Scholar, PubMed, the World Bank and the Internet Archive. Every source that is included, and every one that is excluded, carries a receipt.
Does Tru8 use AI to decide what is true?
No. AI is used to decompose claims, retrieve evidence and classify it by source type and tier. It never scores credibility and never issues a verdict. The judgement stays with you.
