HelixNotes

HelixNotes saves every note as a plain .md file directly on your local disk — there is no proprietary database, no cloud account, and no vendor lock-in. The app is built on Tauri (Rust) with a SvelteKit frontend, which keeps the binary small compared to Electron-based alternatives. You can open and edit your vault with any Markdown editor, including cat from the terminal.

HelixNotes does not run its own sync server, but it supports WebDAV so you can sync against any WebDAV-compatible endpoint you control. This is a bring-your-own-sync model where files remain plain .md on your disk and the WebDAV layer handles replication. For mobile, the project also ships an Android app that opens the same vault format without requiring an account.

Yes — HelixNotes has an Android app (tested on Android 16) that opens the same Markdown vault without requiring an account. It includes the editor with tables, the Tasks view, the graph view, and Daily Notes, so the core desktop feature set is mirrored. There is no iOS build yet, and the project explicitly notes that it is not a hosted workspace or team collaboration suite.

HelixNotes includes a built-in Obsidian import path, so existing Obsidian vaults can be opened in HelixNotes without manual conversion. [[wiki links]] are supported natively, and the graph view renders connections automatically from those links. An external .md viewer mode lets you browse notes outside the main app as well.

HelixNotes is built on Tauri (Rust) for the desktop shell and SvelteKit (Svelte/TypeScript) for the UI, which keeps memory and binary size low. Full-text search is powered by Tantivy, the Rust search engine, with CJK awareness built in. Optional AI features can run locally through Ollama, or with your own API key.
