Sider Not Working on YouTube? Causes and Fixes (2026)
Sider sidebar not summarizing YouTube, missing on the page, or out of credits? The usual causes — daily credit allowance, extension conflicts, YouTube layout changes — with fixes.
Quick answer: Sider problems on YouTube usually come down to the daily credit allowance being exhausted, the sidebar failing to inject after a YouTube update, or the video lacking captions. Because Sider is a general AI assistant rather than a YouTube-specific tool, its credits are shared across every feature — so heavy chat or translation use can leave nothing for video summaries.
1. Out of credits
Sider's free tier provides a daily credit allowance shared across all its features. Summarizing a long video costs more than a short chat exchange, and once the daily pool is gone, summaries fail — sometimes without a clear message. Check your credit balance in the sidebar before assuming a bug.
Fix: wait for the daily reset, upgrade, or use a tool with a separate allowance for video.
2. The sidebar does not appear
Sider injects a sidebar into the page. YouTube layout changes and Chrome extension policy updates can break injection.
Fix: reload the page, update the extension, restart the browser, then reinstall if needed. Same class of problem as any in-page tool — see summarizers breaking after updates.
3. The video has no transcript
Sider reads the caption track. No captions, no summary. Verify with Show transcript under "...more" in the description — details in "no transcript available" fixes.
4. Long videos fail or truncate
Long transcripts can exceed the model's context on lower tiers, producing partial summaries that look complete. Check whether the final third of the video is represented — see summaries cut off on long videos.
5. Model selection
Sider lets you choose models, and cheaper or free-tier models handle long transcripts less reliably. If summaries are poor rather than absent, try a stronger model before concluding the tool is broken.
The structural tradeoff
Sider is an all-purpose AI sidebar; YouTube summarization is one feature among many. That breadth is the appeal, and also why video summaries compete for the same credit pool as everything else. It is also extension-based, so no iPhone use.
If YouTube summarizing is what you actually do, a dedicated tool avoids both issues. YT Summarizer is web-based with one-time credits — 1 credit per video of any length, 5 free, then packs from $19 that never expire, with nothing shared with other features and no daily reset.

Frequently Asked Questions
Why is Sider not summarizing YouTube videos?
Most often the daily credit allowance is exhausted. Sider's credits are shared across all its features, so heavy chat or translation use leaves nothing for video summaries. Other causes are sidebar injection failing after a YouTube update, or the video having no captions.
Do Sider credits apply to YouTube summaries?
Yes, and they are shared with every other Sider feature. Summarizing a long video costs more than a short chat exchange, so a long video can exhaust what remains of a daily allowance in one go.
Why are Sider's YouTube summaries poor quality?
Often model selection. Cheaper or free-tier models handle long transcripts less reliably. Try a stronger model before concluding the tool is broken — and check whether the final third of the video is covered, which indicates truncation.
Is Sider worth it just for YouTube?
Rarely. It is an all-purpose AI sidebar where video summarization is one feature among many, so you pay for breadth and your summaries compete for shared credits. A dedicated tool is cheaper and does not share an allowance.
