Libreta is a tool for building auditable financial models using plain text files (CSV and YAML) instead of Excel spreadsheets, designed for AI agents to write and humans to review. It provides a CLI and live browser view, with traceable formulas and checks, aiming to replace brittle spreadsheet or code-based modeling with diff-friendly text.
