Most Reddit keyword tools ping you hours late and on every mention. SubredditSignals surfaces matching posts within about five minutes and filters them for buying intent — so your alerts are worth acting on, not muting.
A keyword alert that arrives after the thread has peaked is just a notification. One that arrives while it is fresh is an opportunity.
SubredditSignals watches new posts as they land through a multireddit new-post fast path, so a matching thread reaches you within about five minutes — not on the next slow poll cycle.
On Reddit, the comment that shows up early gets the visibility and the upvotes. By the time a slower tool notices a post, the thread is crowded and your reply is buried.
Our own detection lag used to sit around 3.3 hours on a polling cycle. Switching to a new-post fast path cut that to roughly five minutes — that gap is exactly the window competitors fill first.
Detection-lag figures reflect SubredditSignals' own measured performance before and after the new-post fast path shipped, shared for illustration.
The reason people abandon keyword alerts is noise. An AI intent layer is what keeps them useful past the first week.
Get scored alerts by email on every plan — or pushed straight into a Slack channel on Pro — plus a single in-app feed you can skim in a few minutes each morning. The near-real-time pings are for the threads that cannot wait until tomorrow's review.
A few of the setups founders use to turn keyword alerts into pipeline. The full walkthrough — seven setups with templates — is on the blog.
Catch “what tool do you use for [category]?” threads — the clearest product-research signal there is.
Fire when someone says they are frustrated with, or looking for alternatives to, a competitor.
Track the phrases people use to describe the exact problem you solve, before they name a category.
Watch the small, high-conversion communities where your buyers actually congregate.

Alerts-only tools stop at the notification. SubredditSignals scores the lead, drafts a reply in your brand voice for you to post, and tracks which subreddits convert. If you are weighing a dedicated alerts tool, here is the honest side-by-side.
Matching posts reach you within about five minutes of going live. That is because we watch new posts as they land through a multireddit new-post fast path, rather than re-scanning subreddits on a slow polling cycle the way many keyword tools do.
Free keyword tools fire on every mention regardless of context, which quickly becomes noise you mute. SubredditSignals adds an AI intent layer on top of the keyword match, so an alert reflects whether the person is actually shopping for a solution — not just that your term appeared somewhere.
To email and the in-app feed on every plan; the Pro plan can also push alerts straight into a Slack channel via webhook. You can skim the scored feed each morning and rely on near-real-time alerts to catch the highest-intent threads while they are still fresh.
Yes. You set the keywords, competitor names, and pain-point phrases for each brand, and tune the minimum intent scores that decide which matches surface as alerts versus staying in the feed. That lets you trade volume for quality based on your capacity.
Everything matching your keywords is still tracked in your feed. The AI layer decides what is worth an alert versus what stays as background — so you get pinged for buying moments without drowning in every passing mention. You can loosen the thresholds any time.
