The Rules, resolved.
Brief is a regulatory applicability engine for UK firms with a focus upon single or dual regulated financial services firms. We use machine learning and artifical ingelligence to turn dense, complex rulebooks into simple, plain English and very specific guidance.
Tens of thousands of provisions across two regulators. Most don't apply to you.
The regulatory landscape that firms face contains tens of thousands of individually numbered provisions across multiple rulebooks. Working out which rules apply has typically meant reading dense application annexes, mapping firm types, and building your own scoping matrix. Today firms do this manually, pay law firms thousands, or rely on generic summaries that aren't specific enough to your firm.
An encoded application matrix and a typed classification.
Brief encodes regulatory rules as a machine-readable matrix. A plain-English question tree resolves your firm's regulatory category — so applying the rules is a database lookup, not a regulatory exegesis.
A provision-level applicability engine.
Classify
Plain-English wizard resolves regulatory category, statuses, activities, and metrics into a typed firm profile.
Match
Profile is mapped to matrix columns derived directly from the FCA's and PRA's own application tables.
Resolve
Typed predicates evaluate activity gates, status checks, thresholds and sequential conditions per provision.
Render
Each provision returns RULE / GUIDANCE / CONDITIONAL / N/A with full reasoning and cross-references.
The architecture separates three layers: chapter-level applicability metadata for chapters not yet modelled at provision level; provision-level matrix rows for fully or partially encoded chapters; and a predicate sidecar for provisions whose applicability depends on firm-specific conditions.
This delivers accurate results across the full sourcebook from day one, progressively deepening to provision-level resolution as encoding is completed.
Built on a modern TypeScript stack with a fully automated test suite and type-checked data pipeline, every JSON change is validated against the schema before deployment.
The engine is regulator-agnostic — the same wizard framework and predicate system applies to any FCA sourcebook or PRA Rulebook instrument, with the matrix and predicate files serving as the only sourcebook-specific inputs. Dual-regulated firms get a single combined view across both regulators.
Complex rules, plain English.
Brief puts complex regulatory topics into plain English for you. Ask them about any provision, chapter or obligation in the FCA Handbook or PRA Rulebook — they'll explain what it means, why it applies, and what you need to do. You can also chat with them about your obligations in real time.
Stop scoping the Handbook by hand.
Select your sourcebooks, answer the classification wizard, and get your firm-specific rulebook.
