## What it is
A jQuery-based autocompletion library that adds GitHub-like @mentions and emoji autocomplete to textareas and contentEditable elements. It is no longer maintained; the README recommends using Tribute instead.

## Use cases
- add @mention autocomplete to a comment box
- autocomplete usernames in a textarea like GitHub
- trigger suggestion dropdowns on custom characters
- add emoji picker autocomplete to an editor

## When to choose
- you maintain a legacy jQuery app already using At.js
- you need IE7+ textarea support with a battle-tested mentions library

## When to avoid
- starting a new project - use Tribute instead
- you need a maintained library with modern framework support
- you don't use jQuery

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components
- domain: frontend, web-development
- platform: browser
- tags: mentions, autocomplete, jquery, coffeescript, javascript
