Source: https://mentio.dev/reddit/ Reddit # Reddit monitoring: keyword alerts for your brand mentions Reddit keyword alerts from every subreddit: posts that name your product, your competitors or your space, scored for relevance, sentiment and intent, so the r/devops thread reaches you while it is still alive.

Being in the thread within the hour is the difference between a customer and a warning, and Reddit monitoring that alerts on every match buries the thread under noise. What we watch ### Posts, not comments Reddit's search covers posts only; the official API has no comment search, so neither does anyone else. Titles and self-text, with the subreddit and author. How often ### Every 30 minutes Each keyword is searched twice an hour, a phrase match so "acme cloud" never turns into "acme" and "cloud". Where it comes from ### The official Reddit API OAuth search on the official API, free and sanctioned, with a fallback provider when it is unavailable. ## Reddit mentions, as Mentio delivers them Every match is scored 0 to 100 for relevance against your company context, tagged with sentiment and intent, and summarised in a line. The same shape reaches Slack, a webhook, the API and your agent. An illustrative mention for a fictional brand, acme. acme 2m ago Su/senior\_devr/devops12K karma Is anyone using acme in production?

One POST per term, or a click in the dashboard. 02 ### The pipeline watches everything Every source is ingested once, matched against your terms, and classified by AI: relevance 0 to 100, sentiment, and intent, tuned by your company context. 03 ### Act on what matters Triage in the dashboard, deliver to Slack or webhooks, query the REST API, or let your AI agent work the feed over MCP. ## Reddit monitoring questions ### Can you set up Reddit alerts for a keyword? Yes. Add a keyword and Mentio searches every subreddit for it every 30 minutes, scores each post for relevance, sentiment and intent, and sends the ones that matter to Slack, Telegram, email, a webhook or your AI agent over MCP. Alerts can be instant or a daily digest. ### How do I track keywords on Reddit without the noise? The AI relevance score is the filter. A post that merely contains your word scores low; one where someone asks whether to use your product scores high. An alert rule can require a minimum score, a sentiment or an intent such as buy intent, so Slack only sees the threads worth answering. ### Is there a free Reddit monitoring tool? Every Mentio account starts with $5.80 of credit and no card: one keyword for a month plus 100 mentions. F5Bot is free and emails raw matches; Mentio adds AI scoring, Slack and webhook delivery and an API, at $5 per keyword per month and $0.008 per mention. ### Does Mentio monitor Reddit comments? Posts only. Reddit's official API has no comment search, so no tool that stays within its terms can alert on comments. Mentio watches titles and self-text across every subreddit and says so rather than pretending otherwise. ### Is Mentio a GummySearch or F5Bot alternative? For keyword monitoring, yes. GummySearch closed in November 2025; its keyword alerts and Slack delivery are what Mentio does across Reddit and nine other platforms, with AI scoring and an API on top. F5Bot stays free for raw email matches. Audience research and subreddit discovery are not part of Mentio. ### Can my AI agent read Reddit mentions? Yes. Mentio's MCP server exposes search and triage tools, so Claude, Cursor, Codex or any MCP client can ask for this week's Reddit mentions with buy intent and answer with the thread in hand.
