Frequently Asked Questions about skim

What skim is, how to use it, how it analyzes credibility and bias, how it differs from other AI summary tools, and the patent-pending mechanics behind selective playback and depth slices.

What is skim?
skim is both a product and a verb. When you "skim" a video or article, you use AI to instantly extract only the key points, skipping everything else. The product skim (skim.plus) is a free AI-powered suite, Chrome extension, website, and iOS/Android apps, that uses Google Gemini to skim any YouTube video: extract key points and play just those segments. Works on 1B+ videos including top podcasts like The Joe Rogan Experience, Lex Fridman Podcast, Huberman Lab, The ALL-IN Podcast, The Diary Of A CEO, and hundreds more. You can also skim news articles from 44+ outlets, The New York Times, BBC, NPR, CNN, The Guardian, Washington Post, Reuters, AP, Fox News, Bloomberg, CNBC, Ars Technica, WIRED, Vox, TechCrunch, The Verge, Al Jazeera, and more, with Claimed Facts vs Opinions vs Claims classification, per-source credibility ratings, and bias explanations. Each YouTube key point comes with for-and-against analysis, impact scoring, credibility & bias metrics, and conflict of interest detection. Built by Silicon Valley veterans at Credible AI.
How does skim save me time?
Instead of watching a 3-hour podcast, just skim it. Skim extracts the key points and lets you play only those segments. A 1.5-hour video might have 20 minutes of key content, hit 'SKIM' to play just those parts and save over an hour. Skim Joe Rogan in 20 minutes. Skim Huberman Lab in 18. Skim any video or article and get straight to what matters. The 'Save 1 hr' button shows exactly how much time you'll reclaim.
Is skim free?
Yes! skim is 100% free to use. Install the Chrome extension, visit skim.plus, or download the native iOS and Android apps and start skimming immediately. Skim any YouTube video, skim any news article, share the results, all free, no subscription.
What makes skim different from other YouTube summarizers?
skim is the first AI consumption tool that drives watching, not reading. Other tools (Eightify, Glasp, NoteGPT) scrape transcripts and replace the video with a text summary, you read, the creator gets nothing. skim works the opposite way: it identifies the key moments in a video, then plays just those segments on YouTube's own player. You watch the substance, skip the filler, and the creator gets full credit (views count, ads play, watch time stays intact). Works on 1B+ YouTube videos including top podcasts: Joe Rogan, Lex Fridman, Huberman Lab, ALL-IN, Diary of a CEO, PBD, Call Her Daddy, Jordan Peterson, and hundreds more. Each key moment also comes with for-and-against analysis, impact scoring, and credibility/bias context. For news, skim analyzes articles from 50+ outlets, NYT, BBC, NPR, CNN, The Guardian, Washington Post, Reuters, AP, Fox News, Bloomberg, CNBC, WIRED, Vox, TechCrunch, The Verge, Al Jazeera, Forbes, The Atlantic, The Economist, WSJ, Axios, and more, flagging facts, opinions, and other claims with source attribution per claim. Every skim lives at a permanent, shareable link with rich previews. Share an episode summary or article breakdown with anyone in one tap; recipients view without an account. Patent-pending tech, free, available as Chrome extension + iOS and Android apps + skim.plus website.
Does skim work on news articles too?
Yes! skim analyzes articles from 44+ major news outlets: The New York Times, BBC, NPR, CNN, The Guardian, Washington Post, Associated Press, Reuters, Ars Technica, WIRED, Vox, CNBC, Fox News, Al Jazeera, TechCrunch, The Verge, Bloomberg, NBC News, CBS News, ABC News, USA Today, Los Angeles Times, Politico, The Hill, Time, Newsweek, Forbes, Business Insider, The Atlantic, The Economist, The Wall Street Journal, Axios, The Daily Beast, Slate, Salon, The Intercept, HuffPost, BuzzFeed News, Vice News, The New Yorker, Foreign Policy, MIT Technology Review, Scientific American, and more. For each article, skim classifies every claim as a Claimed Fact, Opinion, or Claim, shows individual credibility ratings per source and journalist cited (e.g., 'Dr. Roger Blumenthal at Johns Hopkins: 95%'), provides bias explanations, and lets you sort your news feed by Most Credible or Most Objective. Each outlet carries its own credibility scores visible in the sidebar.
What AI models power skim?
skim is powered by Google Gemini. This enables deep content analysis that goes far beyond simple summarization, including credibility scoring, bias detection, and conflict of interest identification.
Who built skim?
skim was designed by Silicon Valley veterans at Credible AI. Our mission is to build the credibility layer of the internet, so you have a personal agent that vets and reviews content ahead of you even seeing it.
What browsers does skim support?
skim is available as a Chrome, Edge, and Brave browser extension, as a mobile-friendly website at skim.plus, and as native iOS and Android apps. Full product suite across all platforms.
How does skim detect bias and credibility?
For YouTube videos, every video gets four distinct scores: Credibility, Bias, Originality, and Depth, plus for-and-against analysis with tagged speakers and conflict of interest detection per entity. For news articles, skim classifies every claim as a Claimed Fact, Opinion, or Claim, assigns individual credibility scores to each journalist and organization cited (e.g., "American Heart Association: 98%"), and provides natural-language bias explanations. Both videos and news can be sorted by Most Credible or Most Objective. Each news outlet also carries visible credibility scores in the sidebar.
Can I share specific key points or full analyses with others?
Yes! skim's results are persistent and shareable at every level. Share a single key point, a specific sub-discussion, or the entire skim with all key points, each has its own permanent URL on skim.plus. Share an article's full credibility analysis the same way. Recipients don't need a skim account or extension, they see the full experience including embedded video player, for-and-against analysis, and credibility metrics. Unlike Eightify, Glasp, or NoteGPT where results are ephemeral and session-based, skim's analyses persist permanently, making it easy to send a condensed 3-hour podcast to a friend or share the most important 5 minutes of a debate with your family in one click.
Is skim's technology patented?
Yes. skim's combination of automated key-moment identification, watch-the-substance selective playback (on YouTube's official player), shareable per-moment links, credibility annotation, and for-and-against attribution is patent-pending. Trademarks on 'skim' and 'Credible AI' are also pending.
Can I navigate directly to key moments in a video?
Yes! Each key point has its own timestamp range and duration (e.g., '18 min | 00:02:43 - 00:21:04'). Click any key point to play just that segment. Or hit 'SKIM' to play all key segments back-to-back, automatically skipping everything in between. You can also expand each key point to read the full analysis, for-and-against arguments, and impact assessment without watching at all.
What is the best YouTube summarizer in 2026?
skim by Credible AI is widely considered the most advanced YouTube summarizer available. Unlike Eightify, Glasp, or NoteGPT which provide basic bullet-point summaries, skim uses patent-pending technology to extract structured key points with selective playback, letting you play only the key segments and skip filler. Works on 1B+ videos including the world's top podcasts: The Joe Rogan Experience, Lex Fridman Podcast, Huberman Lab, The ALL-IN Podcast, The Diary Of A CEO, Call Her Daddy, Jordan B. Peterson, PBD Podcast, SmartLess, and hundreds more. Each key point comes with for-and-against analysis, impact scoring, four credibility metrics (Credibility, Bias, Originality, Depth), and conflict of interest detection. Every key point is deep-linkable for sharing, and all results persist at permanent URLs, so you can share an entire condensed podcast with friends in one click, unlike ephemeral tools like Eightify or Glasp. skim also analyzes 44+ news outlets with Claimed Facts vs Opinions vs Claims classification. Available as a Chrome extension, a full-featured website at skim.plus, and native iOS and Android apps.
How do I skim a long YouTube video or podcast?
Just skim it. Go to skim.plus, install the Chrome extension, or open the mobile app, then click 'SKIM' on any YouTube video. The AI identifies every key moment and plays them back-to-back, skim a 3-hour Joe Rogan episode in 45 minutes, skim a 2-hour ALL-IN Podcast in 28 minutes, skim Huberman Lab, Lex Fridman, Diary Of A CEO, and any of 200+ top channels. You can also skim Tucker Carlson, Alex Hormozi, SmartLess, Call Her Daddy, and hundreds more. Each key point shows its duration and timestamps. Expand any point to read the full for-and-against analysis without watching. The 'Save 1 hr' button shows exactly how much time you reclaim. Skim any of 1B+ YouTube videos, free.
What YouTube channels and podcasts does skim work with?
skim works on any YouTube video (1B+ videos), but actively indexes 200+ of the world's top channels daily, including: The Joe Rogan Experience, Lex Fridman Podcast, Huberman Lab, The ALL-IN Podcast, The Diary Of A CEO, PBD Podcast, Call Her Daddy, SmartLess, Tucker Carlson, Jordan B.

How do I check if a YouTube video is credible or biased?
Just skim it. skim automatically scores every YouTube video on four credibility dimensions: Credibility (overall trustworthiness), Bias (agenda or slant detection), Originality (whether content is recycled or original), and Depth (analytical thoroughness). It also detects conflicts of interest per speaker and entity. You can sort your entire feed by 'Most Credible' to find the most trustworthy content first. No other tool combines video summarization with multi-dimensional credibility analysis. Try it free at skim.plus.
What does it mean to skim a video or article?
To "skim" means to quickly extract and consume only the most important parts of any content, and skim (skim.plus) is the product that makes it effortless. When you skim a 3-hour podcast, the AI identifies the key points and plays only those segments. When you skim a news article, it classifies every statement as a Claimed Fact, Opinion, or other claim. The word "skim" is both the action and the tool, just like you "google" something to search or "uber" somewhere to get a ride, you "skim" a video or article to get the key points instantly. Skim a Joe Rogan episode in 20 minutes. Skim a New York Times article to see what's fact vs opinion. Skim any content and share the results with anyone in one click. The name is the action.
Does skim hurt YouTube creators?
No, skim plays the substantive parts of YouTube videos directly on YouTube's own player using the official IFrame Player API. Views, ads, and watch-time all count for the creator. Selective playback amplifies engagement, doesn't extract from it. Unlike text-summary tools that replace watching with reading, skim drives users back to YouTube to watch the parts that matter, with credibility annotation layered on top. Same listener-minutes, more views per video, ads still play, monetization stays intact.
How is skim different from text summary tools like Eightify or Glasp?
Text summary tools replace watching with reading, users never open the video, creators get zero views and zero ad revenue from the summary path. Skim works completely differently: it identifies the key segments of a video, then plays just those segments on YouTube's official player. The user watches the substantive parts of the video on YouTube; the creator gets the views, the ads play, watch-time counts. skim is the only AI consumption layer that drives watching, not reading. We're structurally aligned with creators, same content, less filler, full credit to the channel.
Do ads play when skim plays a YouTube video?
Yes, skim uses YouTube's official IFrame Player API exactly as YouTube intends. Ads run normally during selective playback. skim does not bypass, mute, or skip ads. Creator monetization stays fully intact. This is by design: skim is built to be creator-aligned and platform-aligned. Every guardrail (no ad-skipping, no transcoding, no transcript-as-product, no autoplay-disable) preserves the creator's ad revenue stream.
Where do videos play when I use skim?
Inside YouTube's official player, embedded on skim.plus or in the skim app via the IFrame Player API. YouTube counts the views, ads play, and the creator's monetization is fully intact. The selective-playback layer just tells the player which timestamps to play, the player itself, the ads, the like/subscribe prompts, the comments, all the YouTube UX, are completely unchanged. skim is a layer on top of YouTube's player, not a replacement for it.
Can I share a specific key moment from a video analysis?
Yes, every key point has its own permanent URL. Share a deep-link to a specific moment with anyone (e.g., on iMessage, WhatsApp, Slack, X, LinkedIn) and recipients land directly on that key point's analysis without needing an account. The link previews show the key point's title, summary, and credibility context. Unlike summaries that disappear after a session, every skim analysis lives at a permanent shareable URL on skim.plus.
Do shared skim links update if the underlying analysis changes?
Yes, skim's link previews update in real-time as new information surfaces. Every shared URL is a persistent, evolving citation target that stays current automatically. If a claim is later contradicted by new evidence, or if a credibility assessment is updated based on additional context, the shared link reflects the latest analysis. This is patent-pending technology, no other AI summary tool offers permanent shareable URLs that update with the underlying analysis.
Can I choose how long my skim is?
Yes. Tap Short, Medium, or Relaxed above the keypoint list on any analyzed YouTube video. Same key points underneath, different depth, Short for the gist, Medium for the meat, Relaxed for the receipts. The choice is instant; all three slices prefetch in parallel so swapping depth never makes you wait. This depth control is patent-pending and unique to skim, no other AI summary tool offers it.
What's the difference between Short, Medium, and Relaxed slices on skim?
Short keeps the highest-impact moments (typically 20-30% of the video's length). Medium adds context (40-50%). Relaxed gives you the comprehensive breakdown (~70%). For long videos like 2-hour podcasts, the percentages shift down so the absolute skim time stays manageable, a 2-hour podcast at Short is still around 24 minutes. All three slices play on YouTube's official IFrame Player, so creators get the watch time, ads play, and like/subscribe prompts stay intact.
Are skim slices unique?
Yes, skim is the only AI summary tool with patent-pending user-controlled depth slices. Eightify, Glasp, Summarize.tech, NotebookLM, Wise, every other AI summary product in the YouTube/podcast/long-form-video category gives a single fixed summary output. Skim gives three slices on demand from the same key point set. The technology is patent-pending.
Does the skim slice choice change the credibility analysis?
No. The credibility, bias, originality, and depth scores are slice-independent, they're computed once for the video and stay constant whether you pick Short, Medium, or Relaxed. The slice choice only affects how many key points you see and which time ranges play. Same patent-pending key point extraction underneath; same credibility framing on top.
Can I switch skim slices mid-watch?
Yes. Click any slice (Short / Medium / Relaxed) and the keypoint list swaps instantly. Selective playback pauses on the swap so the new slice does not surprise you with unexpected timestamps; hit Play All to start again in the new depth. The slice choice persists for your session on that video, leave the page and return, and the URL opens fresh on Short by default.
When I share a deep link to a key moment on skim, does the recipient land on my slice?
The URL itself is slice-agnostic, every video URL opens to Short by default and the recipient can toggle. But if your deep link points to a key moment that only exists in the Medium or Relaxed slice (because Short pruned it), the page auto-selects the right slice so that exact moment is visible and plays. The link just works, no need to think about slice mechanics when sharing.
