Built for AI-native engineering

The intelligence platform
for code reviews.

Stop guessing which files matter. PRism computes a mathematical attention score for every changed file — so reviewers know exactly where to focus.

CORE PLATFORM

Built for scale.

Every PR is parsed into an AST, mapped into a dependency graph, and analyzed across 6 dimensions of risk in under 30 seconds.

🎯
Attention Score
AS(f) = 0.40·R + 0.35·D + 0.25·C — tells you exactly which files need line-by-line review.
🔐
Security Risk
AST pattern matching detects JWT issues, SQL injection, eval(), auth bypass patterns.
💥
Blast Radius
Graph centrality shows how many services break if a changed file fails.
🧠
Decision Memory
Architectural decisions stored permanently. Search why any change was made, forever.
👃
PR Smell Detection
Flags God PRs, missing tests, Friday merges before a single reviewer opens the diff.
👥
Reviewer Matching
Recommends reviewers by actual commit history on changed files, not random assignment.
