Tolaria is a local-first Markdown knowledge base with native relationships, Git history, and AI workflows. Each note is a Markdown file with YAML frontmatter rather than a database or proprietary format. It includes a block-based editor with wikilinks and an integrated Git client for committing, pushing, and browsing history. AI features cover local CLI coding agents and local or API model providers. It is free and open source, with desktop builds for macOS, Windows, and Linux.
wikmd is a file-based wiki that uses Markdown documents, converting them to HTML for viewing in the browser. Features listed include git support, image support, math and LaTeX, code highlighting, file searching, a dark theme, a knowledge graph and basic password protection. Data is stored as files rather than in a database.
Notion World helps clean, compare, sort, transform, count, or format text in the browser.
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.
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.
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.
Butterfly helps clean, compare, sort, transform, count, or format text in the browser.
