Baker Street

Baker Street is a free-form tool that helps you produce natural deduction proofs in propositional logic. Use Baker Street to enter your proof, check for errors, clarify relationships between proof lines, preview, and export your proof in several formats. Type your proof in a free-form manner. Baker Street provides automatic line numbering and feedback to help you see where you've gone wrong. Baker Street is great for creating new proofs, inspecting sample proofs, and exporting them to a variety of formats, all within a native macOS experience. Baker Street was developed by Ian Hocking under the supervision of Dr Olaf Chitil at the School of Computing, University of Kent, UK, as an MSc Computer Science summer project. Key features: - Proof validation - Syntax highlighting - Tailored error messages designed to get you on track - Add text comments to your proof - One-touch insertion of logical operators and inference rule justifications - Preview your formatted proof while typing in a lightweight markup language - Export or copy your preview to LaTeX, Markdown or HTML - A plain text file format - if Baker Street goes away, your proofs won't - Zoom support for all windows - Dark mode support - Example proofs for all inference rules (e.g. AND Introduction) - Further help on: - Inference rules (in overview and in detail) - Key term definitions (e.g. theorem)
