§01

Who these terms are with

keytwelve.ai is operated by Crosby Thirty-Three. These terms cover your use of this website. They are not an agreement to use the product — access is arranged separately, in writing.

§02

What this site is

This site describes what KeyTwelve does and shows a worked sample. The property in that sample is synthetic and disclosed as such. Nothing here is an offer, a valuation, or a representation about any real property or transaction.

§03

Not advice

Nothing on this site is investment, tax, legal, or accounting advice, and nothing here should be relied on as a substitute for your own diligence or your own advisers.

§04

Requesting access

Submitting a request does not entitle you to access. We read every request and reply, including the declines, and we can decline without giving a reason. What you send us is handled as described in the privacy notice.

§05

What belongs to us

The text, design, and material on this site belong to us. You are welcome to read it, link to it, and quote it with attribution. Reproducing it wholesale, or presenting it as your own, is not permitted.

§06

Using the site sensibly

Do not try to break, overload, or circumvent the site's protections, and do not use automated means to retrieve it at a volume that degrades it for anyone else.

§07

Liability

We are liable without limitation for intent and gross negligence, and for injury to life, body, or health, and under the Produkthaftungsgesetz. For slight negligence we are liable only where we breach an obligation essential to the purpose of these terms, and then only for damage that was foreseeable and typical. Beyond that our liability is excluded.

The site is provided as it is. We do not promise it will always be available or free of error.

§08

Links to other sites

Where we link to something we do not run, we do not control it and are not responsible for its content.

§09

Changes

We update these terms when what we do changes. The date below is when they last changed.

PrivacyTerms
  1. The property on this site is synthetic and disclosed. A synthetic property with known ground truth is the only way to measure extraction against an answer key — we know what the documents say because we wrote them. Accuracy figures, when we publish them, will come off holdouts that are never made public.
  2. Deterministic means the kernel returns the same figure for the same inputs on every run, and emits the operand tree behind that figure alongside it. Model-assisted extraction reads the documents; the arithmetic downstream of extraction does not vary between runs.
