Mentions scattered through conversation
On social platforms, a mention is a username with @ in front of it, and it is how people get someone’s attention. Mentions scatter through posts, comments, replies and chat logs. When you need the full list, for example to thank everyone who took part, to invite the same people again, or to check who was involved in a discussion, finding them by hand means reading everything and hoping you missed nobody.
An extractor does that reading for you. It pulls every @username out of the text and hands you a clean list, one mention per line, ready to copy.
How this tool works
Paste any text and press Extract mentions. The tool finds every @ followed by letters, digits or underscores, which is the username format used on most platforms. Each mention goes on its own line in the result.
One detail matters: email addresses are not mentions. An address like joe@example.com contains @ followed by letters, but it is not a username. The tool checks the character before the @ and skips matches that are part of an email address or a dotted name, so your mention list is not polluted with email domains.
Remove duplicates, on by default, keeps each person once, which is what you want when someone was mentioned ten times in a thread. Sort A to Z arranges the list alphabetically for easy comparison. Copy the result with one button.
Common uses
Event organizers collect everyone mentioned in an announcement thread to build a guest or thank-you list. Community managers find who was mentioned in a discussion so nobody is left out of a reply. Creators gather the accounts they collaborate with regularly. Researchers map who talks to whom in a sample of posts.
It is also useful for moderation and review: extracting mentions from a heated thread shows who was actually pulled into the conversation, which is often a shorter list than it felt like at the time.
What counts as a mention
Most platforms allow letters, digits and underscores in usernames, and that is what this tool matches. A mention at the start of a line, after a space, or after punctuation like a parenthesis is matched. A mention inside an email address or after a dot is not, by design.
Some platforms allow dots or hyphens in usernames. Those characters end the match here, so a username like @mary-jane would be extracted as @mary. If your platform allows those characters, check the results for truncated names before using the list.
Privacy and etiquette
Everything runs in your browser, so the text you paste is never uploaded. That matters when the text is a private group discussion or a client’s material.
Having a list of mentions does not grant permission to message everyone on it. Mentioning someone in a post notifies them, and mass-mentioning people who did not ask to be included is a fast way to annoy them and to trip spam filters. Use the list for people who took part, who asked to be included, or who would genuinely want to know.
Tips
Extract from the whole thread, not just the first post: the people mentioned in replies are often the ones who matter most. Deduplicate before counting, because a raw count exaggerates the role of the most-mentioned person.
Sort the list when you want to compare it with a member list or a previous event’s list. Keep the original order when you want to see who was brought in first, since the order of first mention often follows the order people joined the conversation. Either way, scan the result once: a truncated username or a missed edge case is easy to spot in a short list.
