About Eightify・AI Video Summarizer
What Is Eightify・AI Video Summarizer
Eightify is an AI tool for people who treat YouTube as a source of information rather than entertainment. It reads a video and returns a short summary, a list of key ideas, and a full transcript, so you can decide in seconds whether a two-hour lecture or podcast is worth your time. The Chrome extension lives inside the YouTube page. One button next to the video starts the summary, with no tab switching and no prompt writing.
The same product is sold under two names. The website and the mobile apps use Noiz, while the browser extension keeps the older Eightify label. Both draw on the same summarization engine, which also lists ChatGPT and Claude as the models behind the text output.
The main limit is scope. Eightify summarizes YouTube content and nothing else. Point it at a Vimeo clip, a Zoom recording, or a local video file and it has nothing to work with. Length is capped at 12 hours per video, and the free tier is a 7-day trial rather than an ongoing free plan, so heavy users end up on a paid subscription.
Getting Started
- Install the Noiz or Eightify extension from the Chrome Web Store, or download the iOS or Android app.
- Open any public or unlisted YouTube video in your browser.
- Click the Summarize button that appears next to the player.
- Read the summary and key ideas, or open the transcript tab for the full text.
- Jump to any section through the timestamps, or share the summary with a link.

Key features
One-Click YouTube Summaries
The extension adds a Summarize button directly on the YouTube page. Clicking it reads the video and returns a short summary plus a bulleted list of key ideas. There is no separate prompt box, no copy-pasting of links, and no second tab to manage.
Timestamped Key Ideas
Each key idea carries a timestamp, so you can click through to the exact moment it came from. This matters for long videos where the value sits in a handful of segments. Jumping by timestamp beats scrubbing through a progress bar by hand.
Video to Text Transcripts
Eightify works as a YouTube transcript generator, turning speech into readable text you can export as a document, a Markdown file, or a paste into Notion. The transcript is the part people keep for research, since it turns a spoken video into something you can search and quote.
Q&A and Brief or Detailed Modes
Instead of one fixed summary format, the tool offers a Q&A view and lets you pick how long the output should run. A quick bullet list suits a fast check; a longer version suits a video you need to study closely.
41-Language Support
Summaries and translation cover 41 languages, so a video in one language can be read in another. This is the feature that widens the tool beyond English-language YouTube, where most summarizers concentrate.
Top Comment Insights
The tool surfaces the most-liked comments alongside the summary. Reader reactions often reveal whether a video's claims are contested or widely accepted, which the summary alone cannot tell you.
Trend Navigator
A weekly list of trending videos lets you spot which topics are gaining traction. It suits creators and marketers who want to catch a subject before it peaks.
Pros and cons
Pros
- Works inside YouTube, so summarizing takes one click with no setup.
- Handles videos up to 12 hours long, well above what most summarizers accept.
- Summaries, key ideas, and transcripts all come from the same pass.
- 41 languages cover non-English videos that many rival tools skip.
- Mobile apps let you summarize away from the desktop.
Cons
- YouTube only, so podcasts on other platforms or local files are out of reach.
- No permanent free plan, only a 7-day trial, so occasional users face a subscription.
- The mobile app has drawn complaints about usage limits appearing after the first video.
- Extension and app use different names for the same product, which can confuse new users.
