Eightify Chrome extension

Eightify uses AI to summarize YouTube videos into key points, saving time on long videos before you decide to watch them in full. It's best for research, learning, and skimming lengthy content. The catch: an AI summary can miss nuance or context that only watching the video would give you.

What Eightify does

Eightify adds a summarization feature to YouTube video pages. When you open a video, it can generate an AI summary that breaks the content down into key points, letting you grasp the main ideas without watching the entire runtime. This is aimed at long videos like lectures, interviews, or tutorials where the core information is spread across a lot of time.

Eightify free vs paid

Eightify offers free summaries, typically with a limit on how many videos you can summarize before hitting a cap. Paid plans remove or raise that limit for people who summarize videos regularly, since running AI summarization on video transcripts has an ongoing processing cost.

Is Eightify safe?

The extension needs to read YouTube page content, specifically video transcripts, to generate summaries. That transcript data is processed by an AI service to produce the summary. It doesn't need access to your Google account credentials just to summarize public videos.

Eightify: FAQs

Is Eightify free?

Yes, it offers free summaries with a usage limit; paid plans are available for summarizing more videos regularly.

Is Eightify safe to use?

It reads video transcripts from YouTube to generate summaries, which are processed by an AI service, without needing your Google account credentials.

How do I use Eightify?

Open a YouTube video, click the Eightify icon or button on the page, and review the AI-generated key point summary.

Does Eightify work on all YouTube videos?

It generally needs a video to have captions or a transcript available, so videos without any captions may not summarize well.

How accurate are Eightify's summaries?

Summaries are AI-generated and aim to capture the main points, but they can miss nuance or context that only watching the full video provides.

What are Eightify alternatives?

Glasp, NoteGPT, and YouTube's own built-in summary features are common alternatives for condensing video content.

Does Eightify have a free limit?

Yes, free use typically comes with a cap on the number of summaries, after which a paid plan is needed to continue.

Why did Eightify fail to summarize a video?

This usually happens when the video lacks captions or a transcript, which the extension needs to generate its summary.

Can Eightify summarize long lectures or podcasts?

Yes, it's designed for exactly this kind of long-form content, where getting the key points quickly saves the most time.

Does Eightify support languages other than English?

Support depends on the availability of captions or transcripts in that language on the source video; check the extension for current language coverage.
