InTruth: A Chrome Extension That Fact-Checks Live Speech in Real Time
InTruth is a free, open-source Chrome extension that listens to your browser tab and labels spoken claims as true, false, or misleading using AI.

A GitHub repository published just days ago has been making the rounds on social media, and for good reason. InTruth is a Chrome extension that listens to audio playing in your browser and fact-checks the speaker's claims on the fly — no pausing, no copy-pasting, no manual searching required.
How InTruth Works
After installing InTruth from the Chrome Web Store, you enter a cloud API key, which the extension needs to run in real time. Once you hit "Start Fact Checking", InTruth's overlay panel appears and starts monitoring the tab's audio stream.
The process unfolds in the background:
- Spoken words are continuously transcribed.
- The extension extracts verifiable claims and key topics from the transcript.
- Those claims are cross-referenced against information pulled from the internet.
- Each claim is labeled true, false, or misleading and displayed in the panel.
All of this happens while the speech continues — there's nothing you need to do except watch.
What Does It Cost to Run?
Costs depend on the API service you use and the length of the content. As a real-world reference point shared by the developer: running InTruth through a lengthy political speech consumed around 20 cents in API credits. A rough estimate for a full press conference puts the cost at around $1. For casual use, the quota consumption is quite low.
Current Limitations
The most notable limitation right now is language support: InTruth currently works only in English. Real-time fact-checking for Turkish-language speech is not yet available. Whether Turkish support arrives in future versions remains to be seen — no official commitment has been made.
How to Get Started
- Install the extension from the Chrome Web Store.
- Generate an API key from your preferred cloud provider.
- Enter the key in the extension's settings.
- Play the content you want to fact-check and press Start Fact Checking.
Because the project is open source, you can review the code, report issues, or even contribute a pull request to add support for other languages.
Final Thoughts
InTruth is a genuinely interesting tool for anyone who regularly watches political speeches, live interviews, or news broadcasts and wants a quick, automated second opinion on what's being said. It won't replace critical thinking, but having a real-time layer of verification running in the background is a meaningful step toward more informed viewing. It's free, open source, and worth trying — especially for English-language content while multilingual support catches up.
