Scratch

It provides a minimalistic environment for creating and editing markdown documents with a live WYSIWYG preview, allowing users to see formatted output while typing. The application stores all data locally, operating without any cloud synchronization, accounts, or subscription requirements. It is built as an offline‑first tool, so notes remain accessible even without an internet connection.

The editor supports standard markdown syntax and renders it in real time, giving a seamless writing experience for users who prefer visual feedback. In addition to basic note‑taking, the app can integrate a local AI agent that runs on the user’s machine, enabling context‑aware assistance without sending data to external services.

As an open‑source project released under a free‑tier license, it is intended for anyone who needs a lightweight, privacy‑focused markdown notpad. The software is considered stable and ready for everyday use on personal computers.
