DropItDown – Drop a file, get Markdown your AI agent can read (macOS)

DropItDown, a free macOS app for Apple Silicon, converts any file dropped onto its menu-bar icon into clean Markdown locally, with on-device OCR for images. The Markdown is filed into a user-specified vault folder with a one-line summary, enabling AI agents to read text instead of binary PDFs, reducing token usage. The app runs entirely on the Mac with no uploads, supports OpenAI-compatible endpoints for classification, and works with Obsidian or any Markdown reader.

Drag any file onto the menu bar → clean Markdown your AI agent can read, filed in your vault. Convert once, locally — stop burning tokens on raw PDFs. Drag → clean Markdown → filed in your vault → handed to your agent. Drag any file onto the menu-bar icon. It’s converted to clean Markdown on your Mac — paste the note’s path into your AI agent and it reads text, not a binary PDF. Whatever lands on your Mac becomes Markdown — documents, images OCR’d on-device , tables, and more. Drag an attachment right out of Mail, Outlook, or a chat app onto the icon — no saving it to disk first. Each note drops into the right folder in your vault with a one-line summary — the sorting runs on your own key. Open the vault in any agent and it searches across every note — the one-line summaries are the index — to answer from your own files. Conversion runs on your Mac — no upload. Your agent reads clean text instead of a binary PDF, for a fraction of the tokens. One click writes a CLAUDE.md so any agent can search your vault. It’s just Markdown — open it in Obsidian, or nothing. Classification runs on your own key — any OpenAI-compatible endpoint. Files stay in your folders; no account, no server.
