Pin

Pin puts a source pin on every claim the model makes. Tap one and the cited passage opens in place, with the words that support the claim marked. A claim without a source gets a pin that says so, and a person can strike it.

Colour

Live specimen

The answer makes four claims. Tap pin 2 to see the notice period in the lease. The last claim has no source: the lease says nothing about a penalty, so strike that sentence.

Anatomy

When to use

On any answer that states facts from documents: leases, reports, minutes, policies.
Wherever people will act on the answer, or forward it.
For how a figure was calculated, use Trace. For a figure that depends on live data, use Tether.

Behaviour

A pin cites the passage, not the document. “Lease, page 14” sends people looking; the marked words settle it.

Best practices

Pin every claim, including the obvious ones.
Quote the passage exactly, and mark only the words that support the claim.
Name the document, clause and page.
Say plainly when a claim has no source, and why.

DoOpen the passage in place, with the supporting words marked.

Don’tDon’t list a document at the end. Nobody can tell which claim it supports.

Accessibility

Each pin is a button named for its source: “Source 2: Lease, §7.2, page 14”.
The passage opens after the answer in reading order; Escape closes it.
The no-source pin says “No source” in its name, not only in ochre.
