AI Commentary on Any Video: Roasted, Analyzed or Explained
BSmeter comments on what a video actually says. Paste a link, or open the browser extension on the video you're watching, and the AI goes through the video claim by claim in one of three voices: Roast (uncensored and joke-first), Analyze (a credibility score per claim, with sources searched for the low scorers) or Learn (explains the topic). Paid plans add realistic audio narration so the commentary is spoken as you watch, and on YouTube any moment can become a clip with the Devil's voiced reaction.
How it works
Pick a video
Paste a YouTube, TikTok, Instagram Reel or podcast link at bsmeter.ai, or open the extension on a video you're playing.
Web, extension or Android app
Choose the voice
Roast, Analyze or Learn. The AI transcribes the video, finds the claims and writes its commentary in that style.
Three commentary modes
Watch, listen, share
Follow the commentary in sync with the video, turn on narration on a paid plan, or clip a YouTube moment to the Doomscroll with the Devil's voice.
Commentary you can share
What you get
Three Commentary Styles
Switch between Roast for brutal, uncensored humor, Analyze for a straight credibility breakdown, and Learn for plain-language explanations of the topic. Same video, three very different takes.
Roast, Analyze and Learn modes
In Sync While You Watch
The Chrome and Firefox extension puts the commentary right on top of the video as it plays, so each reaction shows up at the moment the claim is made instead of in a report afterwards.
Commentary synced to the video in your browser
A Spoken AI Voice
Basic and Premium add realistic audio narration, so the commentary is read aloud over the video instead of only shown as text.
Realistic AI narration on paid plans
Reaction Clips With the Devil's Voice
On YouTube videos, tap Clip on a moment and it becomes a short reaction clip on the Doomscroll: the real moment, then the Devil's voiced roast. Watching the Doomscroll is free and needs no account.
Voiced reaction clips, free to watch
The Crowd's Take Too
Alongside the AI's commentary, BSmeter surfaces the sharpest viewer comments at the moments they are relevant, so you see what the AI caught and what the audience caught.

Frequently asked questions
What is an AI commentary video generator?▾
A tool that adds an AI's reactions or analysis to a video. BSmeter does it for videos you did not make: it transcribes a YouTube, TikTok, Instagram or podcast video and comments on each claim as a roast, a credibility analysis or an explanation, in sync with the video.
Can the AI react to a video while I watch it?▾
Yes. Open the Chrome or Firefox extension on the video and, once the analysis is ready (seconds to minutes), the commentary appears on the video as it plays, timed to the moments the claims are made. Paid plans can also read it aloud with realistic AI narration.
Can I make a reaction video to post?▾
BSmeter makes reaction clips on the Doomscroll, shared as links: the real YouTube moment followed by the Devil's voiced roast. It does not export MP4 files. You can also download a roast card image in square or 9:16 format from any analysis.
Is it free?▾
Yes. The free plan covers 3 videos a day, up to 30 minutes each, in all three commentary modes. Audio narration comes with Basic ($3.99/month) and Premium ($8.99/month).
