Noise disguised as signal.

A keyword match ≠ an opportunity.

Existing monitoring tools promise more alerts, more coverage, more platforms. You end up with 20–50 notifications a day — most of them irrelevant. The signal gets buried. You stop checking. The tool becomes shelfware.

Founder attention is scarce. A tool that's supposed to save attention shouldn't consume more of it.

rising Show HN: a minimal vector store
Discussion turning toward retrieval strategy — your angle.

AI discovers. Humans contribute.

The tool handles the tedious part — scanning threads, detecting which ones matter, catching them while they're still climbing. You handle the valuable part — writing something thoughtful that genuinely adds to the discussion.

01 once

Describe your product once.

Tell us what you build, who it's for, and what problems it solves. This becomes the context we use to evaluate every thread — not a keyword list, but an understanding of where your product actually fits.

product context, not keywords
02 continuous

We catch threads in their momentum window.

The system watches comment velocity, upvote patterns, and engagement. AI evaluates each rising thread against your product context — and finds the ones where your perspective would genuinely add value.

03 1–3 / day

You get an email while the window is still open.

Each alert includes the thread, why it's relevant to your product, and what kind of contribution would feel natural. No drafted replies. No templates. Just the right thread, at the right time.

The line between useful and spam.

    Auto-post or auto-reply on your behalf.

    The tool never writes anything under your name. You are the one contributing.

  • ×
    Draft generic promotional comments.

    No AI-generated replies. Your voice stays yours — because that's the whole point.

  • ×
    Send every keyword mention.

    If it's not rising and not relevant, it's not an alert. Quality is the filter, not quantity.

  • ×
    Try to game or spam Hacker News.

    Authentic contribution wins. Everything else is a short-term play that ends badly.

One price. Full product.

No alert caps. No tiered feature gates. No per-thread billing. You pay for one product; you get the whole thing.

Quality is the constraint, not quantity — so capping alerts would make the product worse, not cheaper. If you monitor more than one product, it's $50 per product.
