Files.md

Files.md stores every note as a plain .md file in a folder you choose on your local disk, accessed through the browser's File System Access API. There is no proprietary database in the critical path — the files are yours and readable by any text editor. The optional server is a single Go binary you can run yourself, or you can skip it entirely and sync the folder via iCloud, Dropbox, or Google Drive.

The app includes a chat-style capture flow (opened with Cmd+Enter) that lets you dump ideas and have them turned into notes without leaving the keyboard. It also ships a Telegram bot for capturing thoughts from your phone, which writes back to the same .md files. The project is described as LLM-friendly: the codebase is intentionally small enough that a single developer or an LLM can fit it in their head.

Files.md is MIT-licensed and the hosted beta at app.files.md is free to use. The repository is primarily Go (about 53%) for the server and vanilla JavaScript for the client, with no build system — you can just open web/index.html in a browser. Chromium-based browsers (Chrome, Brave) currently have the best File System Access API support.

Unlike Notion, Files.md does not store your data in a remote database — every note is a local .md file you fully own. Compared to Obsidian, the editor is browser-based rather than a desktop app, and the project emphasises simplicity and AI-extensibility over a plugin ecosystem. Built-in Telegram capture and an LLM-friendly codebase round out a deliberately minimal toolset.
