Otterly

Otterly is a free, open-source desktop application for writing and organizing Markdown notes. It stores all files as plain .md files in a folder you choose, giving you full ownership and portability. The app includes a clean editor with live formatting preview, full-text search across all notes, bidirectional linking between notes, and version history integration with Git.

Designed for macOS, Windows, and Linux, Otterly requires no account or sign-up. It offers customizable themes and keyboard shortcuts, and lets you open notes in other applications. The project describes itself as an Obsidian alternative that prioritizes staying close to plain files. According to build evidence, the application was developed using Claude for coding assistance.
