Updates
What changed and what we've built, in reverse chronological order — the most recent at the top. Here we report the news that changes what the service can do and how well it does it, with the technical detail useful to anyone who wants to understand how it works.
The archive opens up: public streams, broadcast overlay, signed verdicts
Three changes that take verification outside the members' area. The first verified streams are now public: the timeline with outcomes and sources can be read without a subscription, and every verdict has its own citable permalink. The broadcast overlay is available: an on-air lower third (OBS, vMix) that shows verdicts live during a programme, with a control-room instruction kit. And every published verdict now carries a digital signature: anyone can check its integrity from its proof page, even long after publication.
A more accessible site and more reliable checks
A round of polish across the site. On accessibility: forms and navigation that are easier to use with a keyboard and a screen reader, and the «field» app now installable on your phone with its own icons. On reliability: verification doesn't waste resources when nobody is watching, resumes without losing anything after a restart, and a momentary technical glitch no longer leaves a wrong verdict behind.
One page for all the tools
We've gathered in one place — the Tools page — every way Cryterio verifies and delivers verdicts where they're needed: live checking, time reference, permalinks, sources (broadcasts, broadcasters, files, phone), embeddable timeline, gallery overlay, archive and export. Each with its status, so it's clear what's available today and what's coming.
Every verdict now says when it was said
On the timeline and the permalink, each check now shows the moment in the broadcast when the claim was made (“said at minute X”): you can trace precisely what was said, and the time reference accompanies the citation. The verdict's issue time is also included in its signature.
The phone as a source: live checking (preview)
First step of the «phone as a source»: from the members' area the newsroom can now start a field session — point the microphone where the speech happens (a rally, a press conference, a council) and the checks appear in a timeline while the person is still speaking, on the same pipeline as broadcasts. In preview for the newsroom; the first step of the direction described in Research.
The newsroom introduces the broadcast, and checks get more precise
When scheduling a broadcast, the newsroom can now write a short introduction — who is speaking and on what topic (“question time with minister X on the Y file”). The system uses it as background context, never as a source, to resolve ambiguity and implicit references (“the president” → which one): fewer “unverifiable” verdicts caused by unattributed names, and better-formed claims. It is optional: without it, checks stay exactly as before.
Not just YouTube: live broadcasts from broadcasters' own sites
Verification is no longer tied to YouTube and Vimeo: the newsroom can also schedule broadcasts that live on publishers' own sites — TV channels and news outlets — by enabling their domains in the configuration. The audio of this content is still verified: the broadcast page links out to “Watch on the publisher's site” and the timeline of checks remains the product. This applies to public statements, respecting opt-outs: publishers who ask not to be included are excluded at the source. A step in the broader coverage described in Research.
Fact-checks now embed where the public reads
Every public live event now has an embeddable timeline: a lightweight widget that a news outlet or website can drop into its pages with one line of HTML, with the outcomes, the sources always cited and a link to the full verification. It is the first step of «verification where the public is watching» described in Research.
Uploaded recordings get verified too
Not all public discourse goes through YouTube: the newsroom can now upload an audio or video file — a rally recorded on site, a press conference received from a press office — and have it verified by the same pipeline as live events, with the timeline in the schedule.
The usage licence is now attested by a document
Professional plan holders can print the licence attestation from the Account page: a document with holder, plan, seats and validity period, to file or attach to newsroom contracts.
Recurring claims now have a memory
Many claims come back, identical, from one live event to the next. The system now recognises them: if an equivalent claim — same figures, same language — was recently verified, the outcome arrives instantly, with the same sources, without re-running the judgement. Faster and above all consistent verdicts: the same figure cannot get two different outcomes a day apart. If a verification is corrected, the memory is updated with it. It is the first step of the «memory of claims» described in Research.
One plan, the whole newsroom: seats are here
The Studio and Organisation plans now include seats: the plan holder invites colleagues from the Account page and each works with their own personal access — no shared credentials. And for those who use the checks in their work, the professional licence puts a right that matters in black and white: citing and republishing individual verdicts in articles and reports, with attribution to Cryterio and the cited source.
Advertising doesn't get fact-checked
During a broadcast, commercials are not public speech: the editorial team can now pause evaluations instantly during the ad break — transcription keeps running, resuming is immediate — and the system recognises advertising windows by itself, avoiding treating the promises of products on sale as claims to verify. A cleaner timeline, resources spent only on the speech that matters.
Every verdict has an address: the permalink
Every check from a public broadcast now has its own citable page: claim, verdict, sources, date and a link to the broadcast, with the preview card for sharing. If a claim is re-judged, the link always leads to the most recent verdict: only one citable version stays in circulation. It is the first building block of the portable verdicts described in Research.
Complete public broadcasts, with verdict charts
Broadcasts made public by the editorial team now share the same layout as the members' area — video on the left, verification column on the right — and, below the video, two charts: the distribution of outcomes and the most-cited sources. The charts are computed in the browser from the data already on the page: no extra load on the servers, the same experience for everyone.
Live search restricted to authoritative sources
Evidence retrieval always starts from our curated index of primary sources; only when the index doesn't cover a claim does a live search step in, limited to a selected set of authoritative public domains (statistics institutes, central banks, institutional and European sources). Every piece of evidence reports its source page; the search never touches the open web. The system rule stands: without a citable source the verdict is non_verificabile, never a claim called false without proof.
A more sober, professional face
Site redesigned in a language of technical precision: cold white, high-contrast typography, electric-blue accent and mono for technical labels. On the home page, a stylised chart of the broadcast over which the verdict markers — green, amber, red, grey — move in real time. Added the The model, Research, Technology and Contact pages; menu and navigation, mobile included, reorganised.
Readable by humans, engines and models
An llms.txt file describes Cryterio to the language models that explore the web — so even AIs know how to cite us for what we are when they talk about live fact-checking. For humans: pages looked after on contrast and keyboard navigation; for search engines, sharing metadata and canonical URLs.
Joining the NVIDIA Inception program
Cryterio joins NVIDIA Inception, NVIDIA's program for startups building products based on artificial intelligence and accelerated computing: access to technical resources and the ecosystem to push research faster.
The system's foundations
The pipeline everything rests on, built one phase at a time, each tested before the next.
In production, with health checks
Put online behind TLS and CDN, with a dedicated health check on every component and automatic shutdown of processing jobs at the end of a broadcast — no resource running without a reason. Infrastructure and account data on servers in the European Union.
The schedule is curated by an editorial team
An internal panel to choose which broadcasts to cover, start and stop the processing of a stream and curate the source index. Broadcasts are chosen by a person, not an algorithm: quality stays high.
Free on invite for the whole beta, then monthly or annual
With an invite, access is free for the whole beta; then subscriptions begin (monthly or annual, −15%) with a native 7-day trial: the card is entered right away via Revolut, no charge during the trial, automatic renewal unless cancelled. Payments are handled idempotently, without silent failures and with card data kept out of our systems.
A product, not a prototype
Landing, public schedule, sign-up and login; members' area with player and timeline side by side, and account page. A middleware blocks access for anyone without an active or trial subscription, both on the pages and on the real-time channel.
The timeline that scrolls with the broadcast
Verdicts reach the browser via WebSocket, synchronised with the player. The work is done once per broadcast and streamed to every connected viewer: more people on the same event don't double the computation (fan-out).
The verdict, anchored to the data
Every claim is compared against an index of primary sources; the judge produces a label — true, imprecise, unconfirmed, unverifiable — with an explanation and cited source. A rule carved into the code and not only into the prompt: without sufficient evidence, or below the confidence threshold, the verdict drops to non_verificabile; calling a claim false without a source is forbidden.
Separating claims from rhetoric
From a sliding window of speech we isolate only what is verifiable — numbers, dates, entities, circumstantiated facts — normalising the values. Opinions, promises and slogans stay out, and a textual deduplication avoids checking the same repeated sentence twice.
Every word transcribed, on our servers
Transcription performed locally, without sending the audio to external services: data that never leaves the infrastructure — a privacy choice.
From URL to audio stream, seamlessly
The system takes a broadcast, extracts its audio and splits it into short windows with an overlap, so no word is cut in half. A single processing job per broadcast: the same verification reaches every viewer, in real time.
We keep improving the source index, the coverage of live search and the accuracy of verdicts, broadcast after broadcast. The open areas are described in Research.
