HelixNotes

HelixNotes is a local-first markdown note-taking application built with Tauri, SvelteKit, and Rust. Unlike cloud-based alternatives, it stores your notes as standard Markdown files on your local filesystem — giving you complete ownership and zero vendor lock-in.

The app features a rich WYSIWYG editor powered by TipTap with slash commands, tables, and code highlighting, alongside a source mode for raw Markdown editing. You can link notes with [[wiki-links]] and explore connections through an interactive graph view. Full-text search is powered by Tantivy for instant results across your entire vault.

HelixNotes supports KaTeX math rendering, Mermaid diagrams, daily notes with a built-in calendar, version history with diffs, automatic backups, and AI writing tools via local Ollama or your own API keys. It runs natively on Linux, Windows, macOS, and Android without Electron — making it significantly faster and lighter than many competitors.
