Commetry is an AI-powered Chrome extension that analyzes YouTube comments instantly. It provides sentiment analysis, identifies discussion themes, and generates summaries to help creators and marketers understand their audience better.

How does Commetry work?

Simply install the Chrome extension and navigate to any YouTube video. Click the Commetry icon, and our AI will fetch and analyze the comments, giving you insights about sentiment (positive, negative, neutral), key themes, and an overall summary within seconds.

Is Commetry free to use?

Yes! Commetry offers free credits to get started. You can analyze videos using your free credits, and purchase additional credits if you need more.

Is my data safe and private?

Absolutely. We use industry-standard encryption and secure data storage. We only access YouTube comments from videos you choose to analyze, and your data is never sold to third parties. You can delete your account and data at any time.

What Google account information does Commetry access?

Commetry uses Google Sign-in solely for account authentication. When you sign in with Google, we request only your email address and public profile name to create and manage your Commetry account. We do not access your YouTube channel, videos, playlists, subscribers, watch history, or any other private Google account data. Public YouTube comments are fetched directly from YouTube's public API using the video URL you provide not through your personal Google account.

Which browsers are supported?

Commetry is available as a Chrome extension, which works on Google Chrome and Chromium-based browsers like Microsoft Edge, Brave, and Opera. We plan to support Firefox and Safari in the future.

Do I need an account to use Commetry?

Yes, a free account is required to use Commetry. This allows us to save your analysis history, manage your credits, and provide a personalized experience. You can sign up with your email or Google account in seconds.

What AI model does Commetry use to analyze YouTube comments?

Commetry uses GPT-4.1 by OpenAI to analyze comments. This advanced language model powers our sentiment analysis, theme discovery, emotion detection, and comment summarization, delivering highly accurate insights from your YouTube audience.

How many YouTube comments can Commetry analyze at once?

Commetry analyzes up to 100 top-level comments per analysis by default, which provides statistically representative insights for most YouTube videos. The comments are fetched directly from YouTube's public API.

Can Commetry analyze comments in multiple languages?

Yes! Commetry supports multi-language comment analysis. Our AI can process and analyze comments written in various languages, making it ideal for creators with international audiences.

How accurate is the AI analysis?

Commetry uses advanced AI model GPT-4.1 to analyze comments. While AI analysis is highly accurate for sentiment and theme detection, results should be used as insights to inform your decisions rather than absolute metrics.

Can I export my analysis data?

Yes! You can export your analysis results as CSV files, making it easy to use the data in spreadsheets, reports, or other tools. Export options are available directly from the extension.
