Methodology · v1 · Nov 12, 2026
Every sentence says where it comes from.
An IRIS brief is a list of claims. Each claim carries one label, the sources that back it, the date the source was published and the date we last read it.
Three labels, never mixed
A public record shows this. Open the source to see it.
e.g. Legora, Inc. filed a Form D notice with the SEC, accepted on Nov 4, 2026.
The company says this in its own filing. The regulator records it but does not audit it.
e.g. Legora reports $220.8M sold of a $550M offering.
Our interpretation of the claims it cites. It is not a fact and is never marked as checked.
e.g. Our read: Legora’s round may still be open.
The company filed the notice. The notice states the amount. The valuation was not published. Those are three different sentences, and we write them as three.
What “checked” means
- A published fact or company statement is marked checked only when a source listed with it backs that exact sentence and that source opens.
- IRIS analysis is never marked checked. It links to the claims it builds on, so you can judge the reasoning yourself.
- Every number keeps its unit, its period and who reports it. Amounts on a Form D are what the company reported; the SEC records filings and does not audit them.
- What the source does not say is written next to the claim: for example, that Form D does not ask for a valuation.
When a source breaks
- When you open the evidence, IRIS checks the source from our servers and shows the time of that check.
- If the original does not respond, we offer an alternate only when it backs the same sentence. If none does, the claim is marked needs review instead of checked.
- If the publisher removed it, we say so and show what the document said when we read it, with that date.
- If your own connection drops, we say that too. It is a different problem with a different fix.
Corrections
Claims are versioned. A correction adds a new version with its date and reason; the old wording stays on the brief. Saved findings show when the claim they point to has changed. Report any claim from its card: the report carries the claim ID and version, so you never have to explain which sentence you meant.
Copying and exporting
“Copy citation” and “Export with sources” carry the same label, source, dates, claim ID and version as the page. Agents get the same record at /api/v1/briefs/<slug>.
What we measure
When you open a brief or a source, copy a citation or save a finding, we record the event, the brief and claim IDs and a random ID kept in your browser. Never your notes, your email or what you type. With Global Privacy Control or Do Not Track on, nothing is sent. Details in our privacy page.
