Is YS Summarizer the same as DeepSum / deepsum.io?

No. Independent paste-a-link YouTube summarizer; not affiliated with DeepSum or deepsum.io.

Do I need a Chrome extension?

No. Paste the YouTube URL on this website in any browser. There is no YS Summarizer Chrome extension sidebar for this flow.

Do you offer chat with the video?

No. Caption-driven text notes only—four styles. Prefer DeepSum when you want their sidebar chat-with-video workflow.

Do Chinese, Japanese, or Portuguese brand searches belong here?

Yes—queries like “DeepSum YouTube AI 摘要,” “DeepSum YouTube AI サマリー,” or “DeepSum resumo do YouTube IA” map to this same DeepSum / deepsum.io comparison page; we do not ship separate pt locale pages for that brand completion.

Do you support multi-hour or unlimited videos like some extension plans advertise?

No. We do not claim that. A common comfort ceiling here is about ~90 minutes when captions exist.

Is summarizing here free?

Yes for the shared daily allowance, with no account required.

DeepSum / deepsum.io YouTube summarizer: any-browser paste-a-link vs Chrome extension sidebar + chat with video

Looking for a DeepSum YouTube summarizer, DeepSum YouTube AI summary, or a DeepSum alternative without installing an extension? DeepSum (deepsum.io) publicly markets an Install-on-Chrome path with a sidebar summary, transcript view, and chat with the video—often with paid tiers for higher limits. YS Summarizer below is a different path: paste a public YouTube URL in any browser—no Chrome extension—for Key Takeaways, Connected Ideas, Structured Summary, or Detailed Article when captions exist, then copy/download Markdown or browser-print PDF. We do not offer an extension sidebar or chat-with-video, and a common comfort ceiling is about ~90 minutes. Prefer DeepSum when you want their Chrome sidebar + video chat workflow; prefer this tool for a no-install paste-a-link summary. We are not DeepSum and are not affiliated with deepsum.io.

DeepSum Chrome sidebar + video chat vs paste-a-link in any browser

DeepSum / deepsum.io publicly leans on a Chrome extension experience: install, open the sidebar beside YouTube, summarize, and often chat with the video. That can be convenient if you already live in Chrome and want in-page capture. YS Summarizer keeps the job on one website page in any browser: link in, caption-based summary out—similar honesty framing as our Eightify / Noiz / Gistly comparison pages. No extension install step for this flow.

Honest limits (no extension sidebar / video chat; ~90 min)

We do not ship a Chrome extension sidebar, do not offer chat-with-video, and do not claim unlimited or multi-hour processing. Captions required; a common practical ceiling here is about ~90 minutes. This page is an independent comparison—not an official DeepSum product page.
