Eightify Not Working? 7 Causes and Fixes (2026)

Quick answer: Eightify usually stops working for one of three reasons — the video has no captions, you have hit the free tier's weekly summary limit, or the browser extension broke after a Chrome or YouTube update. Test with a short, popular English video: if that summarizes fine, the problem is the original video; if it also fails, the problem is the extension or your account limit.

1. The video has no captions

Eightify reads the transcript, not the audio or picture. If the creator disabled captions and YouTube has not auto-generated them, there is nothing to summarize. Check by opening the video description, clicking "...more", and looking for Show transcript. No transcript button means no summary — from any transcript-based tool.

Fix: pick a different video, or wait a few hours if the upload is very recent — auto-captions typically appear within 1–4 hours.

2. You have hit the free weekly limit

Eightify's free tier caps how many summaries you can generate per week. When you hit the cap it often fails quietly rather than showing a clear message, which reads like a bug. Check your account status in the extension popup.

Fix: wait for the weekly reset, upgrade, or move to a tool without a recurring cap. This limit is the single most common reason people look for an Eightify alternative.

3. A Chrome or YouTube update broke the extension

Extensions that inject into the YouTube page depend on YouTube's layout staying stable. When YouTube changes its DOM, or Chrome tightens extension permissions, extension-based summarizers break until the developer ships an update.

Fix: update the extension, restart Chrome, then remove and reinstall it if the button still does not appear. If it keeps breaking, a web-based tool avoids this class of failure entirely because there is nothing injected into the page.

4. The video is too long and the summary truncates

Very long videos produce transcripts that exceed the model's context window. Some tools handle this by chunking; others silently summarize only the first portion. If your summary of a two-hour podcast only covers the first half hour, this is why — and it is the most dangerous failure because the output looks complete. See why YouTube summaries get cut off.

5. The video is private, unlisted, or age-restricted

Tools can only read publicly accessible videos. Private, members-only, and age-restricted videos are blocked at the source. More detail in summarizing private and age-restricted videos.

6. Regional or account issues

Some videos are geo-restricted, and some extensions behave differently when you are signed out of YouTube or using a VPN. Try the same video in a normal window, signed in, without a VPN.

7. Another extension is conflicting

Ad blockers, privacy extensions, and other YouTube add-ons can block the scripts a summarizer needs. Disable other extensions one at a time to identify the conflict.

Quick diagnosis table

Symptom	Most likely cause	Fix
Button missing on YouTube page	Extension broke after update	Update or reinstall extension
Spins forever, no output	No captions on the video	Check "Show transcript" exists
Worked yesterday, not today	Weekly free limit reached	Wait for reset or switch tools
Summary stops halfway	Long-video truncation	Use a tool that chunks transcripts

If it keeps breaking

Extension-based tools have a structural fragility: they live inside a page that Google keeps changing. A web app has fewer moving parts — nothing is injected, so a YouTube redesign cannot break it, and it works on mobile and on managed work laptops where extensions are blocked.

YT Summarizer is a YouTube summarizer with one-time pricing — credits from $19 that never expire, no subscription. You paste a URL instead of installing anything, five summaries are free, and there is no weekly cap to hit. If Eightify's limit is what is actually blocking you rather than a bug, that difference matters more than any fix above.
