Where it falls short
Limited features
Poirot is a macOS app designed for developers, offering functionalities such as browsing Claude Code sessions, exploring code diffs, and re-running commands. It reads local transcripts, supports offline operation, and is open source. The app features a clean interface and practical functions, ideal for developers who frequently need to review and backtrack code changes.
From registration to actual use - step by step
Visit the GitHub repo to clone the project. Poirot is a code search and analysis tool that helps developers quickly locate code snippets in large codebases.
Visit GitHub RepoRun Poirot to index the target codebase. Indexing parses code structure, recording symbol definitions and reference relationships. Large projects may take several minutes for initial indexing.
Add index files to .gitignore to avoid committing. Incremental indexing only processes changed files—much faster.
Use Poirot's search syntax to query symbol definitions, references, or text content. Supports regex and file type filtering. Results highlight matches with context.
Use "references" rather than searching function names directly to find call sites, not just definitions.
Before refactoring, use Poirot to find all reference points to ensure none are missed. After refactoring, verify all callers work correctly with test coverage to ensure safety.
Search the entire codebase for references before renaming public APIs to assess impact before making breaking changes.
