Tags are only as good as the person applying them at the end of a long shift. Contact reasons get skipped, the "Other" tag fills up, and the report the team relies on starts to drift. Aide tags every message, chats a teammate handles included, so routing rules and reports cover the whole queue.
In the inbox, each message shows its topic as a chip. Open it to see how sure Aide was, mark it right or wrong, or move the example to the right topic. In Zendesk, the tag and the field land in the same ticket update as the rest of Aide's changes.
