02 — the flow

Three steps.
None of them involve scrolling.

  1. 01step

    describe what you sell

    Drop in your product, ideal customer, and a handful of subreddits. We translate that into keyword clusters with relevance weights — no regex, no boolean gymnastics.

    takes about 90 seconds
  2. 02step

    we scan the firehose

    Every few minutes we pull fresh submissions across your watched subreddits, enrich with metadata, and score each one against your monitors.

    < 4 minutes from post to alert
  3. 03step

    you reply to the 90s

    Open the queue. Threads are pre-ranked by opportunity score. Reply, dismiss, or send to Slack. We track what converted so your scoring gets sharper over time.

03 — what’s in the box

Built for founders who’d rather
ship than scroll.

core

Opportunity scoring that actually
knows what a good thread looks like.

A 0–100 score per thread, calibrated on real responses. Question posts beat link dumps. Fresh beats buried. Specific beats generic. You open the top of the list and it’s worth opening.

discovery

Subreddit discovery

Paste a product description, get 20 ranked subreddits where your buyers already post. We weight by size, activity, and topical fit.

velocity

Real-time triggers

Webhook, email, or Slack — under 4 minutes from the post going up to landing in your inbox. Reply while the OP is still refreshing.

api

REST + MCP endpoint

A clean REST API, plus a JSON-RPC MCP server your agents can call natively. Let Claude or Cursor pull scored opportunities straight into your workflow.

workflow

Queue, not inbox

Ranked list, keyboard shortcuts, one-click dismiss. The UI is deliberately shaped like a task queue — because replying on Reddit is work, and tools should respect that.

The questions
we get most.

Didn’t see yours? hey@redditscanner.ai — a human reads them.

How is this different from GummySearch, F5Bot, or a saved search?

A saved search gives you matches. We give you a ranked queue. Every thread gets scored on freshness, engagement velocity, and how much it reads like a buying signal vs. a vent — so the top of your list is the part worth replying to.

Will this get me banned from Reddit?

We only read public data — no posting, no upvoting, no scraping logged-in sessions. How you choose to reply is on you. We nudge toward helpful over spammy because the ROI is higher anyway.

How fresh is fresh?

Pro users get hourly scans, Team gets real-time via Reddit's streaming endpoints. Median delay from post-to-alert on Team is about 3 minutes 40 seconds.

What does the scoring actually weigh?

Freshness (40%), keyword + subreddit relevance (35%), and engagement signals like comment velocity and upvote ratio (25%). Question-style posts get a bonus. Memes and link dumps get a penalty. Full breakdown in the docs.

Can my AI agents use this?

Yes. Pro includes a REST API. Team adds an MCP endpoint — Claude, Cursor, or any MCP client can pull scored opportunities directly into context.

Do you store Reddit content?

We cache thread metadata and scoring features for 7–30 days depending on plan. Full text of replies isn't stored. GDPR-safe, DSAR-ready.
