Buyer Profilerv0 · previewHigh Caliber AI ↗
▸ The agentic AI marketer

Right now, somebody is asking the internet for what you sell.
You'll never see them.

Buyer Profiler does. It watches Reddit, Hacker News, and the open web for buying-intent conversations matching your ICP, drafts a genuinely helpful reply, and queues it for your one-tap approval. Not an audit. Not a copilot. An agent that does the work.

▸ Live demo

Paste your URL.
Find recent buying signals.

We'll fetch your site, derive your ICP, scan Reddit and Hacker News for the past month, and show up to 5 strong matches with draft replies. Some searches may find none. Hacker News is live; Reddit access is currently unreliable.

No signup. Public URLs only. Cached 24h per URL.

▸ The closed loop

Most "AI SDR" tools fake step four. We close the loop.

Anyone can scrape Reddit. Almost nobody can also tell you whether what you said three weeks ago moved your AI search visibility. Buyer Profiler can — because it's built on the same infrastructure as BrandReceipts.

  1. 01 · Observe
    Continuously scan 6 public sources

    Reddit, Hacker News, Perplexity SERPs, HARO, GitHub Issues, job postings — for posts asking for what you sell.

  2. 02 · Decide
    Score every signal against your ICP

    Lovable AI ranks each match 0-100 for buying intent. Only the top 10 per day make the queue.

  3. 03 · Act (gated)
    Draft a genuinely helpful reply

    Concrete, specific, no marketing-speak. Posted via your own account — your voice, your reputation. You approve every send.

  4. 04 · Measure
    Track what actually converted

    Profile views, DMs, replies, meetings booked. Pulls from BrandReceipts to also see if your AI visibility moved.

  5. 05 · Learn
    Re-rank sources and tactics weekly

    Approval rate + downstream conversions feed back into the scorer. The agent gets sharper every week you use it.

▸ Manifesto

The difference between a tool and an agent is whether it does the work.

  • BrandReceipts watches what AI says about you.
    Buyer Profiler watches what buyers ask for.
  • Most AI marketing tools draft for you.
    Buyer Profiler acts for you, with your approval.
  • Most growth tools optimize attention.
    Buyer Profiler surfaces the moment of intent.
  • Other agents race toward more autonomy.
    Buyer Profiler is approval-first by design — never spammy.
  • Other tools post in their voice.
    Buyer Profiler posts in yours, from your account.
