Blackletter
Legal Intelligence

Deep, jurisdiction-specific legal intelligence —
built by attorneys, not algorithms.

Blackletter builds deeply annotated legal intelligence scoped to specific jurisdictions and legal issues. We start where the major legal databases stop.

What We Build

The annotated corpus
is the product.

The major legal databases give you opinions. Blackletter gives you what those opinions mean — at the level of specific language, enforcement patterns, and doctrinal outcomes. Built case by case, field by field, by attorneys who understand what they're coding.

01
Attorney-Built
Every data point is coded by a practicing attorney with real domain expertise. Not crowdsourced. Not generated. The judgment embedded in the corpus is the product's core value.
02
Narrow by Design
We work within a specific jurisdiction and a specific legal issue — going deeper than any horizontal platform can justify. New York law is where we start. Doctrinal precision is what we deliver.
03
AI-Ready Structure
The corpus is annotated for machine use — structured fields, controlled vocabularies, outcome labels. Ready to power predictive models, fine-tuning, and retrieval-augmented legal tools.

Why It's Different

Where the platforms end,
we begin.

Beyond the database
The major legal databases index opinions. Blackletter annotates what those opinions decide — at the clause level, the outcome level, and the doctrinal pattern level.
Deeper than legal AI
Existing legal AI tools process text. Our intelligence is structured by attorneys who understand the doctrine — not inferred from it after the fact by a model.
A compounding asset
Each new issue corpus follows the same model — proprietary, attorney-annotated datasets that grow in value as the library expands across issues and jurisdictions.
