It is distributed mainly as a Chrome extension, so instead of copying text into a separate tool you can summarise and explain a page right where you found it. That low-friction placement is the point: the tool is meant to slot into an existing browsing habit rather than demand a new workflow. Its core jobs are summarisation and explanation. Long articles can be distilled into the essentials, and YouTube videos can be turned into the key points without watching start to finish. For startup knowledge workers — founders, marketers, salespeople and product managers — that means faster grounding when researching a market, a competitor or a topic that just came up in a meeting. The product fits a category of lightweight AI copilots that augment browsing rather than replace it. It will not do your thinking for you, and summaries should still be checked against the source for anything high-stakes, but it removes a meaningful amount of reading overhead from the day. Check the official site for the current feature set and plan limits, since AI assistant products in this space evolve quickly. **Pricing & Plans:** ExplainThis is generally offered as a free-to-start AI assistant with paid options for heavier usage. Review the official site for current pricing, as details may change. - **Page and article summarisation:** Turn long articles and pages into a readable summary so you can decide what deserves a full read. - **Video explanation:** Get the key takeaways from YouTube videos without sitting through the entire runtime. - **Browser extension workflow:** Primarily a Chrome extension, so it sits alongside whatever you are already browsing rather than forcing a separate app. - **Built for fast-moving teams:** Built for startup knowledge workers who need context fast across marketing, sales and product research. - **Explanations on demand:** Ask follow-up questions about the content you are viewing to dig into the parts that matter to you. **Strengths:** Sits inside the browser as a Chrome extension, so there is nothing new to launch; Handles both web pages and YouTube videos; Speeds up research for founders, marketers and product teams; Useful for triaging which long articles actually deserve a full read **Limitations:** Relies on a browser extension, so it is most useful inside desktop Chrome; Summary quality depends on how well the page is structured; You need to review AI output before acting on it for anything important; Best experience requires signing in, which some users prefer to avoid [Profile (Markdown)](https://openaitools.app/tool/explainthis.md) ## Noiz Noiz is built around a simple promise: skip the watching and still get the knowledge. Instead of copying a link into a separate tool and crafting a prompt, you install a browser extension, open a YouTube video, and click summarize. Noiz returns the key ideas as a clear list, optionally with timestamps that jump to the exact moment, plus a full video-to-text transcript when you need the words, not just the gist. It handles everything from a two-minute clip to a multi-hour course or podcast. The product also ships mobile apps for iOS and Android, so the same summaries are available when you are away from your desk. Beneath the summarizer sits a wider library of free AI utilities covering transcripts, PDF and article summaries, text summarizers, content generators, and YouTube growth helpers like title, description, and tag generators. Summaries can be translated into more than 40 languages, and a weekly top-100 view helps you track what is trending on YouTube. Noiz positions itself as a learning and productivity companion rather than a media downloader. The audience is students, researchers, and professionals who consume a lot of long-form video and want structured notes instead of raw playback time. It reports more than half a million users, with a free trial that leads into a paid subscription. **Pricing & Plans:** Free trial, then paid subscription. You can test Noiz before subscribing; plans are purchased through the extension or mobile apps. Check the official site for the latest prices and tiers. - **Key Ideas Extraction:** Get the essential points from any topic and length of video as a short list or a detailed breakdown, without watching the whole thing. - **Timestamped Summaries:** Each summary point carries a timestamp that links back to the moment it came from, so you can verify or jump straight to the relevant section. - **Video to Text Transcripts:** Convert YouTube audio into accurate, readable text that you can scan, quote, or use as notes for research and study. - **41-Language Support:** Summarize and translate content across 41 languages, making international lectures, interviews, and creators accessible in your own language. - **Browser Extension and Mobile Apps:** Summarize directly on YouTube from the extension, or on the go with the dedicated iOS and Android apps, so learning fits wherever you are. **Strengths:** Summarizes on YouTube itself, with no tab switching or prompt writing; Timestamped summaries make it easy to verify and jump to source moments; Handles very long videos up to about 12 hours, including podcasts; Companion iOS and Android apps extend it beyond the desktop browser [Profile (Markdown)](https://openaitools.app/tool/noiz.md) ## Frequently Asked Questions ### How do ExplainThis and Noiz compare in monthly traffic?
