Xournal++ is an open-source, cross-platform note-taking software, described as a feature-rich modern rewrite of the original Xournal program. It is available for MacOS, Windows, and Linux. The app supports handwritten note-taking with pressure-sensitive styluses and drawing tablets, offers customizable pen, highlighter and eraser tools, includes layers for complex notes, page previews, and supports adding images and various shapes for scientific and general note use.
Memos is an open-source, self-hosted note-taking app that provides a timeline for quick notes written in Markdown. New memos are private by default, and visibility can be limited to the author, invited people, or anyone with the link. The software is MIT licensed, sends no telemetry, and can be deployed with Docker.
HelixNotes is a local markdown note-taking app built with Tauri, SvelteKit, and Rust. Notes are stored as standard Markdown files on the local filesystem. The Codeberg repository is a historical backup; the project has moved to GitLab and is no longer updated there.
Docmost is an open-source, self-hosted collaborative wiki and documentation tool presented as an alternative to Notion and Confluence. It offers real-time collaborative editing, team spaces with permissions, comments, page history, public sharing, nested navigation and diagramming tools. An optional enterprise edition adds SSO, AI and API access. It can run in air-gapped environments with no external dependencies.
Notion World helps clean, compare, sort, transform, count, or format text in the browser.
SiYuan is an open-source, local-first, privacy-first note-taking app. It offers Markdown, block references, bidirectional links, databases, and multi-device sync for personal knowledge management. Content is organized at the block level, with built-in block-level and span-level elements, and blocks support zoom-in focus with breadcrumb navigation. A free tier includes local storage; PRO features require a one-time purchase and third-party sync services.
QOwnNotes is an open source markdown note-taking application for Linux, macOS and Windows that works together with Nextcloud Notes. Notes are stored as plain-text markdown files on the computer, and sync services such as Nextcloud can be used to sync notes across devices. It is described as a native application optimized for speed and low processor and memory use.
