Introducing the Truth Terminal Chrome Extension
ArAIstotle's Polymarket analysis on every market plus live fact-checking on every video, podcast, and article you watch or read. Same extension. Two superpowers.
TL;DR: We've launched a Chrome extension that brings the Truth Terminal's verification engine into your browser, with two flagship capabilities. On Polymarket, get ArAIstotle's full market analysis (independent probability, delta vs. the crowd, full reasoning, source citations, and resolution risk scoring) in a side panel on every market. Everywhere else, the Live Fact Checker transcribes YouTube videos, podcasts, and articles as you watch or read, extracts factual claims, and returns verdicts with sources in real time. No copying links. No switching tabs. Same extension. Two superpowers.
Install from the Chrome Web Store. Verification should live where you're already looking.
For the past year, we have been writing about why prediction markets need an external verification layer, independent probability estimates, source-weighted reasoning, and structural risk scoring like the Resolution Fragility Score. And we have spent even longer building the engine underneath all of it: real-time verification of factual claims, from any source, anywhere on the internet.
Both have worked. Both get used. But they have lived in their own tabs. A Polymarket trader who wanted ArAIstotle's read had to leave the market, open another window, find the question, wait for analysis, switch back. A viewer watching a news clip or a podcast had to pause the video, copy-paste a claim, search elsewhere, and lose the moment. Friction in both directions.
Today, we are closing both gaps with a single product. We've launched a Chrome extension that brings two of Facticity's core tools directly to wherever you are in your browser ArAIstotle's Polymarket analysis on every market, and live fact-checking on every video, podcast, and article.
Same extension. Two superpowers.
What the Chrome Extension does on Polymarket
Open any Polymarket market. The extension recognizes the market automatically and offers ArAIstotle's full analysis, the same engine that powers the Truth Terminal, directly in a panel alongside the page.
What you see for each market:
AI vs. crowd at a glance. ArAIstotle's YES probability, the market-implied price, and the delta between them, color-coded so you can read the edge instantly.
Full reasoning. The model's rationale, supporting evidence for YES and NO, and clickable sources with reliability ratings.
Resolution risk scoring. Both the Resolution Risk Index (RRI) and the Resolution Fragility Score (RFS), which we have written about, so you know not just where the price is wrong, but whether the market itself can be cleanly resolved on.
News and odds velocity. How ArAIstotle's read has moved with the headlines over time.
Term definitions. Ambiguous wording in the resolution criteria was clarified. The "exceed," "by," and "confirmed" language that have broken resolutions before.
Cached results load instantly. Fresh analyses run with live progress, stage by stage. No copy-paste, no tab-switching, no waiting.
Top Deltas, on every page
The Top Deltas leaderboard, the live ranking of the biggest AI-vs-crowd edges across Polymarket, is built into the extension. Tap any market on the leaderboard to open its full analysis. The biggest opportunities surface themselves; you do not have to go looking for them.
The Live Fact Checker: verification right where you watch
The extension's second superpower has nothing to do with Polymarket and it is the feature most users will use most often.
YouTube. Podcasts. News articles. Substack pieces. Long video essays. Anywhere claims are being made faster than you can verify them, the Live Fact Checker runs in the background of your current tab, transcribing what is playing, extracting factual claims as they appear, and returning verdicts with sources in real time.
No copying links. No switching tabs. No pausing the video to Google something. Just live verification as claims are made.
How it works:
It listens. Transcribes what is playing in your current tab, YouTube captions, podcast audio, and page audio.
It extracts. Pulls factual claims from the transcript as they appear, scoring each one by how check-worthy it is.
It verifies. Runs the highest-priority claims through Facticity's verification engine automatically. Lower-priority claims can be reviewed manually or set aside.
Each claim returns a verdict True, False, or Unverifiable, with sources. You can filter by verdict, adjust the rate limit, watch live progress as claims are processed, and review skipped claims later in a dedicated tab. Nothing is ever lost.
This is a fundamentally different tool from the Polymarket analysis. The Polymarket panel is for traders pricing specific markets. The Live Fact Checker is for anyone reading or watching anything and it works on every page, every video, every podcast, every article.
It is also the feature with the broadest reach. Most people are not trading on Polymarket. Almost everyone is watching something.
Sources, weighted by reliability
Every ArAIstotle verdict and every fact-check produced by the extension uses the same source-weighting model that runs in the Terminal. Sources are graded by independent third-party media reliability ratings, including our integration with the Ad Fontes Media Bias Chart.
This matters more in a browser extension than it does on a dedicated site. When fact-checks pop up over a YouTube video or alongside a Polymarket market, the user has seconds to decide whether to trust the verdict. Showing the sources and showing how they are weighted makes the verdict legible in those seconds. No opaque "we say it's false." Just the receipts, with the reliability ratings attached.
Chat with ArAIstotle, in context
A chat interface is built into the extension. Open it on any market or any fact-check and ask questions. Get clarifications on the reasoning. Push back on the verdict. Drill into specific sources. It is the same model that produced the analysis, ready to explain itself without you leaving the page.
Access tiers
The extension signs in with your Facticity account. There are two tracks:
The Live Fact Checker is available to any signed-in user and runs on your existing fact-check credits.
The Polymarket analysis features ArAIstotle market analysis, Top Deltas, and Chat require a Facticity Pro subscription, a Gold or Platinum $FACY stake tier, or a redeemed access code or trial.
If you do not qualify yet, the extension shows you exactly how to get access. The Live Fact Checker is fully usable in the meantime.
What the extension does not do
The extension reads the page you are viewing and sends content to Facticity's servers for analysis. That is it.
It does not modify Polymarket. It does not place trades. It does not move your funds. It is a verification layer, not a trading interface.
We are not affiliated with Polymarket. ArAIstotle insights and fact-check results are AI-generated research and are not financial advice. Always do your own research.
Why this matters now
Prediction markets are increasingly being read as signal by journalists, by policy observers, by autonomous AI agents. The category is being asked to do truth-discovery work for a wider audience than its original users. That role only holds up if verification keeps pace with attention.
The Truth Terminal at araistotle.facticity.ai will continue to be the home for traders who want a dedicated verification workspace, the full leaderboard view, side-by-side comparisons, and deep dives across markets. The Chrome extension is for the other half of the workflow: the moments when you are already on Polymarket, or already watching a video, and verification needs to be one click away from where you are.
Both surfaces. Same engine. Same source-weighted reasoning. Same independent probability estimates.
Verification you have to look for is verification you mostly skip. Verification that is already on the page is verification you actually use.
Install the extension today
The extension is free to install. Sign in with your Facticity account to start. The Live Fact Checker is ready to use the moment you install it. Polymarket analysis is one upgrade away.
