Eightify Review 2026: One-Click YouTube Summaries

Eightify is a one-click YouTube summarizer that adds a summary button to videos, producing timestamped breakdowns, key insights, and translations in 40+ languages. It ships as a Chrome extension plus mobile apps, and its vendor says the system has processed over 10 million videos. The catch: free access is limited to a small number of summaries per week, and unlimited use sits behind a Pro subscription.

Bottom line: The fastest way to skim a YouTube video before committing to it — great for students and researchers triaging video content. The free tier is a taster, not a tool; budget for Pro if you’ll summarize videos daily.

Eightify’s whole pitch is zero friction. Open any YouTube video, click the Eightify button, and get a chapter-by-chapter summary without leaving the page — no copying links into a separate app. Summaries come with timestamps for jumping to the relevant moment, and you can adjust style, type, and length before generating. The tool also exposes full transcripts (via a “cc”-style button in its panel) with copy support for both summary and transcript, and translation across 40+ languages. Dedicated mobile apps extend the same workflow to phones, which third-party roundups rate as one of the better mobile summarizer experiences.

Key features

One-click in-player summaries: A summary button inside YouTube’s interface — no tab-switching or link-pasting.
Timestamped breakdowns: Chapter-by-chapter summaries with clickable timestamps for navigation.
Key insights: AI-extracted takeaways and highlighted keywords, not just a wall of text.
40+ language translations: Summarize and translate across dozens of languages.
Customizable output: Adjust summary style, type, and length before generating.
Full transcripts: View and copy the video’s full transcription alongside the summary.
Mobile apps: Dedicated iOS and Android apps for summarizing on the go.

Who it’s for

Eightify fits students triaging lecture recordings, researchers scanning interviews and conference talks, and professionals keeping up with video content they don’t have time to watch fully. It’s at its best for structured educational videos, where chapter breakdowns map cleanly onto the content. Casual viewers who just want the gist of a 20-minute explainer will also get value — though the limited free quota means even casual use eventually pushes toward paid. Anyone needing bulk processing, APIs, or content repurposing (turning videos into blog posts or slides) should look at more workflow-oriented alternatives.

What to watch out for

Eightify only handles YouTube — no podcasts, no uploaded files, no general web pages. Free access is limited to a small number of summaries per week (the exact quota varies by source), so it functions as a trial rather than a usable free tier; one third-party test even required entering payment details for a 3-day trial. Summary quality varies by video type: structured educational content summarizes cleanly, while interview-heavy or unstructured videos come out messier. Compared with some rivals, there’s no Q&A chatbot for interrogating a video and no content-repurposing export — it’s summaries and transcripts, full stop.

Pricing

A limited number of free summaries per week (exact quota varies). Pro is reported from around $4.99/month — check current pricing on eightify.app, since third-party sources disagree on the exact figure and the vendor changes it. Paid plans unlock unlimited summaries, customizable lengths, multilingual support, and full transcriptions.

Frequently asked questions

Is Eightify free?

Partially — you get a limited number of free summaries per week (the exact quota varies). Unlimited summaries require the Pro subscription, reported from around $4.99/month. Check current pricing on eightify.app.

How does Eightify work?

Install the Chrome extension (or mobile app), open any YouTube video, click the Eightify summary button, and it generates a timestamped summary with key insights — plus an optional full transcript.

Can Eightify summarize videos in other languages?

Yes — it advertises translations and summaries in 40+ languages.

Does Eightify work on videos without captions?

It generates from the video’s audio/transcript pipeline, but quality depends on clear speech; heavily unstructured or noisy videos summarize less cleanly.

Can I ask follow-up questions about a video?

No — Eightify focuses on summaries and transcripts. If you need interactive Q&A with video content, look at tools that explicitly offer a video chatbot mode.
