Comment Pulse

About

Comment Pulse helps you find useful comments faster.

Instead of scrolling endlessly through long comment sections, Comment Pulse adds a compact floating sidebar directly on supported pages. You can fetch comments, search locally, filter by author, sort by engagement, and quickly spot the overall mood of the conversation.

Use it to find:

song names
movie or scene references
people mentioned in a video
timestamps
repeated questions
highly liked replies
positive, negative, or neutral reactions
dominant conversation atmosphere
Comment Pulse is useful for:

researchers
creators
journalists
moderators
music fans
video viewers
anyone trying to understand large comment sections quickly
Key features:

Search comments without manually expanding every thread
Works with YouTube through a secure backend API
Supports public Reddit threads
Includes visible-comment support for Facebook and other platforms
Local sentiment and atmosphere analysis
Engagement sorting
Author filtering
Export results to JSON or CSV
Compact draggable interface
No YouTube API key required for users
Privacy-focused design:
Comment Pulse does not require users to enter API keys. YouTube comment fetching is handled through a backend service, while search and analysis happen locally in the browser whenever possible.

Comment Pulse is built for people who want to understand conversations faster, not just read them one by one.
