KeyMentions is a web-based Reddit marketing tool that tracks brand names and keywords and sends an alert when a relevant discussion is active. The site markets it under the tagline Marketing on Autopilot and aims it at people who want to reach customers through Reddit threads that already draw traffic.
Beyond alerts, the product includes an AI comment generator and an auto publish option that posts replies for the user. The homepage cites 500+ users and says the tool also watches for competitor mentions. The site does not state when the company was founded or where it is based.
The homepage describes a four-step flow. A user creates a project, sets the keywords to monitor along with an expiry for the monitoring, receives notifications in the dashboard and by email, and then generates a comment with the AI bot. Users can run more than one project, depending on the plan.
Comments can be published manually, or the send-to auto-publish feature posts them automatically. Monitoring can be limited to keywords that appear in viral discussions, so alerts focus on threads with traffic instead of older posts that surface through Google searches.
Monitoring features include keyword and brand tracking, competitor mention alerts and real-time tracking on every plan. Alerts are customizable, so users decide when and why they are notified, with settings based on how viral a discussion is. Notifications appear in the dashboard and are sent by email.
On the engagement side, the AI comment generator drafts replies to relevant posts, and auto publish can post them. Plans also differ in project count and data retention, which ranges from none on the Free plan to 2 years on Agency. The source pages list no third-party integrations.
