## Review summary

Users praise the extension for accurate, fast summaries and translations, with strong YouTube transcript support and rich customization through prompts. It’s valued for context-aware results and open-source Firefox availability. However, recurring concerns center on needing a Gemini API key and confusing setup with inconsistent sources, plus UX bugs around custom actions and options. Mobile users report UI glitches (content overflow, dark mode readability). Some updates temporarily break features like video summaries and trigger 403/API issues, highlighting reliability and documentation gaps. Overall, powerful but with setup and stability caveats.

### Pros

- High-quality summarization and translation.
- Supports summarizing pages and YouTube transcripts/subtitles.
- Rich customization via custom prompts and prompt options.
- Fast, context-aware summaries on the current page.

### Cons

- Requires Gemini API key; setup can be confusing and key sources/instructions are inconsistent.
- Custom actions/prompts do not always work reliably and documentation is lacking.
- Mobile UI issues such as content overflow with large fonts and hard-to-read input in dark mode.
- Post-update reliability issues (e.g., video summarization can break; occasional 403/API problems) and guidance gaps.
