Journalistic integrity is hard to see. We make it measurable.
Primary is two things built on one idea. A publication whose reporting is traceable to the source material behind it — and an index that scores journalism on the rigour of the work itself.
Reporting built from the record, and published with it.
Reporting with a visible foundation
Primary publishes articles built from primary-source material — including filings, records, statements, interviews, and other original sources. Every article begins with that material, and the editorial direction is centred on surfacing it clearly, presenting it in a readable format, and keeping a visible evidentiary trail through the piece.
Trust starts with traceability
When readers can see the basis for a story, trust improves. Primary is designed to preserve the connection between published reporting and the source material behind it.
Every sentence that states a fact carries the source it came from — named, dated and linked.
From source to story
Primary is built to connect reporting back to the materials that underpin it. That includes source references, structured article relationships, and a model that makes evidence more legible to the reader.

Quality can be scored, not just asserted
Most ways of judging quality in a field are informal, reputational, and slow to evolve. They lag behind who is actually crafting the best work in real time. We believe quality can be scored directly, from the work itself, using a consistent, transparent, first-principles methodology.
The Primary Index
The Primary Index is our first product: a public ranking of journalists based on the originality and integrity of their reporting. Every profile is built from a journalist’s public body of work and scored by our methodology — not follower count, not outlet prestige, but the work itself.
A profile shows how a journalist ranks against everyone else covering their category, their region, or their industry: how an entire corpus of work scores across multiple metrics, and how the craft has evolved over time.
The Index is the beginning. It is the first proof point for a broader idea — that quality is measurable, in almost any field, if you build the right rubric. We are starting with journalism. It will not be where we stop.
We are a team of engineers and scientists focused on using the latest in AI technology to analyse society’s hardest problems.

Reporters
Our reporters interview the researchers behind each story and show them the draft before it runs. Anyone we interview sees their words in place before publication, attributed by name, and the full transcript is kept with the story’s sources.

The evidence trail is part of the story
Primary is building toward a model of publishing where source transparency is not hidden in the background. It is part of the product, part of the reading experience, and part of what gives the reporting weight.
