CommentFinder

Paste the URL of the post or video whose comments you want to search, then enter what you are looking for, whether that is an exact phrase, a word or a username. Choose how many comments and replies to fetch, from 50 on the free tier up to 1,000 on premium. CommentFinder retrieves the comments including nested replies and returns the matches with counts and surrounding conversation context, so you can see what a comment was responding to. Export the results as CSV or JSON if you need them outside the tool. Credits deduct per batch, purchased as one-time top-ups with no subscription, and they never expire.

• •Nested Replies Included - Searches inside reply threads, which most comment tools skip and where the comment usually is
• •Three Platforms - YouTube, TikTok and Instagram public comments
• •Search by Phrase, Word or Username - Find a specific comment or track a specific person's participation
• •Conversation Context - Matches shown with surrounding conversation rather than as isolated lines
• •CSV and JSON Export - Results usable for research and analysis outside the tool
• •Selectable Batch Size - From 50 to 1,000 comments and replies depending on plan
• •No Subscription - One-time credit top-ups with credits that never expire
• •Free YouTube Search - YouTube is free, plus one free TikTok or Instagram search

For creators wanting to find what their audience actually said on a specific video, and for social media managers tracking whether a particular person or complaint appeared in a thread. Researchers analysing public discourse get the CSV and JSON export, which turns it into a data collection tool rather than only a lookup. Anyone who has tried to find a helpful comment they half-remember is the everyday user. The non-expiring credits suit occasional use, which is how most people will need it, and the free YouTube tier covers a lot of that.
