CONVOLENS fact-checks a debate while the claim is still on the table. Each check shows a verdict, the reasoning and the sources, with the exact wording from the transcript, so a moderator or a watching team can raise it in the moment. It hears the debate through a room microphone or the broadcast playing on your computer, without joining or altering anything.
CONVOLENS is available on Mac, Windows, and Linux.
In the flow
Load the record. Follow the claims. Publish with care.
Bring the positions and statements in, follow the checks as they appear, and take exact quotes from the transcript.

Import the positions, previous statements and your own research before the event. Use Chat to prepare the claims you expect to hear.
Follow the claims
Fact Check surfaces checkable statements from the transcript with a verdict, an explanation and sources when available. Ask Chat or Voice to check a specific line when it matters.
Publish with care
Every check stays with the session. Reopen it from History and ask Chat for the exact wording; CONVOLENS keeps the transcript, not the audio.

What can CONVOLENS check?
Publicly verifiable claims, with web sources. Claims about private records need a connected tool with read access to those records. Opinions and predictions are not checkable.
Is a verdict final?
No. Unverified means the evidence did not settle it, and a card with no sources says so. When a speaker corrects a figure, the claim is checked again.
Can several people follow the same debate?
Each computer runs its own session. A producer can run CONVOLENS beside the broadcast while the host stays on camera.
Can I fact-check a debate I am watching, not hosting?
Yes. Choose System Audio Only as the audio source and CONVOLENS checks the claims in the broadcast playing on your computer.
Who decides what is true?
You do. Each card gives a verdict with its reasoning and any sources it found.
Which platforms does CONVOLENS run on?
CONVOLENS is available on Mac, Windows, and Linux. It needs the microphone permission and, for calls, the system-audio permission. The download page is where a computer installs it. On a phone, tablet, or Chromebook, nothing downloads.
Can I try it before paying?
Yes. Start free with limited monthly usage. The app shows your current allowance, and you choose a plan in the app.
