Inside the instrument

A used-hardware listing walks in. A verdict walks out.

Every deal you see went through the same machine: a hunt that says what you want, a benchmark that says what it's worth, four checks that say whether it's real. Here's how the machine works, and why you can trust the number it lands on.

Part 1 · Input · The hunt

Tell it what you want. It watches from there.

A hunt is a saved search with a price bar: what you're after, how much you'll pay, where to look.

Target = the price you'd love. Ceiling = the most you'd pay. Anything above the ceiling never reaches you.

Say it in part numbers ("AMD Ryzen 9 9950X3D") or in plain English ("a MacBook for school, good battery"). Both become the same thing: a set of criteria the machine checks every listing against.

Cadence: it re-reads the market daily on Free and every two hours on Pro/Lifetime. When a scan finds a listing that clears your bar, the alert goes straight to Telegram, Discord, Slack, Pushover, or ntfy.

Part 2 · Reference · The price benchmark

"Good price" isn't a feeling. It's a number with a sample size.

Every scanned listing lands in a running history of real asking prices per component. That history becomes a benchmark: the median, the p25 (low end), the p75 (high end), and how many observations back it up.

So "underpriced" means something concrete: below the median of N real recent listings, not below a guess.

The benchmark ages. The machine tracks freshness, meaning how long ago those prices were actually seen, and won't pretend stale data is current.

Scores are snapshots, not forecasts. A listing scored yesterday is yesterday's read on it. The benchmark is real observations, with the sample size shown. Thin data is labeled thin, not padded.

Part 3 · Judgment · The four checks → one verdict

Watch one listing run through all four checks.

A 1–10 score isn't one opinion. It's four checks run together. Each check passes or flags. The score is the sum of those four answers, and the verdict is the score's plain-language translation.

This is the machine working on real inputs. The reading is static here; the interactive demo below lets you drive it.

Input NVIDIA GeForce RTX 3080 · 10GB · $340 · tested, original box
01 · Price Asking price vs. the benchmark: $340 vs $460 median (p25/p75 window) → 26% under
02 · Fit Does it match what your hunt asked for? Model, capacity, condition: matches hunt "RTX 3080, used, under $450"
03 · Seller The signals a careful buyer checks: history clean, feedback established, no warning signs
04 · Risk The scam tells: thin descriptions, new accounts, prices below a believable floor. None detected.
8.9/10
ALERT

The one line: "26% under median, specs verified, seller clean. This is a buy."

We never dress up a bad deal. Excitement scales with how good the price actually is. You get a readout, not a sales pitch.

Part 4 · Output · Alert / Watch / Skip

Three outcomes. One of them is worth your time.

You set the bar (target vs ceiling), so you only get pinged when a listing clears your line. ALERT is the machine saying: this one is the real deal.

Alert Cleared your bar.

Price under benchmark, specs match, seller clean, no scam flags. Worth opening now.

Watch Worth knowing, not worth rushing.

It scored well but didn't clear the bar.

Skip Didn't clear.

Overpriced, wrong fit, or flagged.
