Claras vs Eightify: two YouTube summarizers side by side

The main differences, explained

What we could check, and what we couldn't

We compare every tool on its own site. Eightify's website returned an access error each time we tried. So everything we say about Eightify here comes from the store listings its developer, Rational Expressions, Inc., wrote: the Chrome Web Store listing, updated in November 2026, the App Store listing, last updated in April 2025, and the Google Play listing. Before you choose, open Eightify's site and check the points this page marks as not mentioned.

What each one is for

Eightify's listings are clear about its job: get the core ideas of a YouTube video fast. Its Chrome listing promises a summary in about 5 seconds, key insights you can shape by focus, format and length, timestamps to jump to the important parts, the top comments, a transcript, and 40+ languages. It is built for deciding whether a video is worth your time.

Claras does that job too, with a different emphasis. Next to the summary and the transcript is Ask AI, which answers questions from what was said, and Claras transcribes videos that have no captions. The same steps work for Instagram and TikTok links and for your own video and audio files, and Bulk Summaries reads a whole playlist or a YouTube search page at once. If all you want is the gist on your phone, much of that is more than you need.

The same job in each: a one-hour interview on YouTube

Say a founder you follow did a one-hour interview, and you want the main points before deciding whether to watch.

In Eightify, its Chrome listing describes clicking the Eightify button on the video for a summary and key insights, with timestamps to jump to the important parts, and the top comments to see how others reacted. It also offers a transcript, and the summary can be shared. The listings don't describe asking questions, or what happens when a video has no captions.

In Claras, sign in with a free account, then paste the link in the web app or click Summarize under the video with the Chrome extension. Claras reads the captions, or transcribes the audio if there are none, and gives you a short overview, key takeaways and a summary for each section. Chapters jump to their moment, and the extension also marks them on YouTube's progress bar. Then ask follow-ups such as "What does he say about hiring?" Ask AI answers from the transcript and usually gives the time as plain text, so you move the player there yourself. On a paid plan, the Comments tab reads the top 100 comments and sums up the main themes and the mood. YouTube Shorts and live links don't work in Claras yet.

What each costs in practice

Eightify's App Store listing offers Eightify Pro as an in-app purchase at $9.99 a month or $59.99 a year. Its Chrome listing offers a 7-day free trial of the extension but gives no prices. We couldn't confirm what stays free after the trial, and the third-party sites we found disagree with each other, so check inside the app before paying. Claras prices are on the pricing page. Claras counts videos, not questions: the free plan includes 3 videos a month and 1 Bulk Summaries run, Pro allows 50 videos a day, and Unlimited has no daily limit. Paid plans start with a 14-day free trial.

Who should choose which

Choose Eightify if

• You mostly decide what to watch on your phone, iPhone or Android, and want the gist fast.
• You want summaries in a language Claras doesn't offer. Claras writes in English, Spanish, Portuguese, French, German, Italian, Dutch, Russian, Polish, Turkish, Arabic, Hindi, Japanese, Korean and Chinese.
• A summary and key points are enough, and you don't need follow-up questions.

For these, Eightify is a good fit, and Claras would be more than you need.

Choose Claras if

• You ask questions about videos, or compare what several videos say.
• You learn from playlists, lectures and long interviews, including ones with no captions.
• You also watch on Instagram and TikTok, or have your own recordings.

If you are not sure

Try both free on the same three videos, including one long one. If the summary is all you read, Eightify may be all you need. If you find yourself asking "where did they say that?", or wanting a whole playlist at once, that is what Claras is for.
