Smart Rename

Smart Rename is a small macOS app that renames your documents by reading their content. Drop in a stack of badly named PDFs and invoices and get clean, consistent file names back — in a single drop.

Every file comes out as YYYY-MM-DD Entity - Subject - Number.pdf — sortable, searchable, predictable. No more Scan_20240312_0001.pdf.

How it works

• Smart Rename reads the document's content.
• Your files go straight to the AI provider on your own API key — no middleman server collecting your data.
• Renames happen in place, and you can undo them.
• It renames a whole batch of files in one drop.

Requirements

macOS on Apple Silicon, plus your own API key from Anthropic. On first launch the app asks for your key, and you are ready in a minute.

Why I built it

I built Smart Rename to organize my own invoices and documents, and to get hands-on experience with AI engineering — using a large language model as a component inside a real desktop app. It is built with Tauri, React, TypeScript, and Rust.
