Chromium extension that adds Gemini-powered Q&A to YouTube using visible video metadata, transcripts, and the user's own API key.
VidQuery - YouTube Q&A Extension is a browser extension created to make a real workflow clearer, faster, and easier to trust. It turns a focused product idea into something people can use, evaluate, and understand without needing to inspect the source code.
Why VidQuery - YouTube Q&A Extension exists
Viewers must scrub long YouTube videos to find specific answers even when the page already exposes metadata and a transcript.
The goal is not simply to add another tool. VidQuery - YouTube Q&A Extension is designed to reduce the friction around that problem and give people a more dependable way to complete the work.
What it delivers
- Users can ask questions about an open YouTube video.
- Answers can use available transcript and visible metadata.
- Users control their own provider credential.
- Maintainers can produce installable GitHub release artifacts.
The experience
Chromium extension that adds Gemini-powered Q&A to YouTube using visible video metadata, transcripts, and the user's own API key.
The project brings the important parts of the workflow into one coherent experience. Its interface and behavior are shaped around the people using it, while the implementation stays focused on predictable results and honest feedback.
What to know
Every product has boundaries. These are the most important considerations for VidQuery - YouTube Q&A Extension:
- Answers are limited by transcript availability and quality.
- Gemini calls require the user's own API key and send bounded video context to an external provider.
- YouTube route/DOM changes and extension permission boundaries can break extraction.
These limitations are presented openly so visitors can understand where the project works well, what it depends on, and what may change in future versions.
Current status
GitHub release available. The current release demonstrates the core value of the project and the main end-to-end experience.
My role was product design and browser-extension engineering, covering browser integration, provider workflows, and privacy. The related case study explains the decisions and delivery process in greater depth for visitors who want the engineering story behind the product.
