How we check things

The publish gate, the verification clock, and what has to be true before a page can enter the search index.

Publishing is earned, not toggled

On most directories, publishing is a checkbox. Here it is a score, computed from what is actually on the page, and an entry below the bar does not enter the search index no matter who wants it there.

Eight signals are measured:

SignalWhy it is measured
One-sentence summaryIt is the answer to "what is this", and it is what an answer engine quotes
Body depthBelow roughly 150 words of real prose, a page cannot say anything a vendor page does not
Filled key factsCounted filled, not declared — ten empty fields are not ten facts
Graph relationsWhat made it, what it runs on, what it replaces. Also how the page gets crawled
Primary sourcesAt least two. Vendor docs, a model card, a paper
Questions people askWritten for this entry, not generated
Stated limitationsWhat it is bad at. Never optional
Original insightOne thing that exists nowhere else: a measured number, a caveat, a gotcha

An entry has to score 60 out of 100 to be indexable. A scraped row with a name, a logo and a borrowed description scores about 14.

Entries below the bar are not hidden. They are reachable, browsable and useful — they simply carry a noindex and stay out of the sitemap, and the page itself says why. It costs nothing to hold a page back and it costs the whole domain to publish ten thousand thin ones.

The verification clock

Every entry carries verifiedAt: the date a human last confirmed the facts on it are still true. That is not the date the record was edited — fixing a typo does not reset it, and the two actions are separate operations on purpose.

How long a verification is trusted depends on what kind of thing it is:

  • Models — 90 days. Pricing and context windows move quarterly.
  • Tools and agents — 120 days.
  • Companies, frameworks — 180 days.
  • Benchmarks, use cases — 270 days.
  • Datasets — 1 year.
  • Concepts — 2 years. The definition of backpropagation is not going anywhere.
  • Papers — 3 years.

At 70% of that interval the entry is marked as ageing, which puts it on the editorial queue. Past 100% it goes stale: the badge turns into a warning to the reader, and the page drops out of the index automatically until someone re-checks it.

This runs on a clock, not on a person remembering. That is the entire point.

What counts as a source

A primary source is the vendor's own documentation, a model card, a published paper, a pricing page, or an official announcement. A news article about an announcement is not a primary source; the announcement is.

Sources are rendered visibly on the page, not just emitted as structured data, because "verified on this date" is only meaningful if you can check it.

What we will not do

  • Invent ratings. We do not collect reviews, so there are no stars anywhere on this site. Our ordering is an editorial opinion and is never presented as a score.
  • Generate comparison pages in bulk. See the editorial policy.
  • State a number without being able to say where it came from and when.

When we get it wrong

We will. Prices change on a Tuesday afternoon and we find out on Thursday. Report a correction — no account needed — and it goes onto the queue with the entry attached.
