What is HelixNotes and what kind of note-taking app is it?

HelixNotes is a local Markdown note-taking app: your notes are plain .md files stored on your own disk, and the app itself is free, open source, and requires no account. It runs on Linux, Windows, macOS, Android, and iOS. It suits people who want a fast personal notes app with rich editing but refuse to hand their notes to a hosted service — and it is explicitly not for teams that need a shared workspace or collaboration suite.

The core idea: your notes, your files, your rules

The tagline on the site is "your notes your files your rules," and the architecture follows it literally:

• Notes are plain Markdown files on your disk, readable with cat.
• There is no HelixNotes cloud and no account to create.
• Sync is optional and entirely yours to arrange — for example, pointing the app at a WebDAV server you control, or syncing the folder with whatever tool you already use.

That last point is the main decision factor. If you want someone else to handle sync, backups, and multi-device access, HelixNotes deliberately leaves that to you.

What you actually get

Editing

A WYSIWYG editor that writes plain Markdown, plus a source mode when you want the raw text. It supports slash commands, tables, code blocks with highlighting, and live KaTeX math. There's an outline panel, tags with autocomplete, callouts, collapsible sections, focus mode, multi-window, and customizable keyboard shortcuts.

Tasks

HelixNotes pulls every - [ ] checklist from across your notes into a single Tasks view. You can set priority and due dates per row, then work in a list or drag tasks around a calendar.

Linking and graph

Notes connect via [[wiki links]], and a graph builds itself as you link. Hovering a node traces its connections.

Daily notes

A built-in calendar with one note per day — click a date to open or create it. Useful for standups, journaling, or thinking out loud.

Search and technical details

• Built on Rust and Tauri rather than Electron.
• Full-text search via Tantivy, with CJK awareness.
• Mermaid diagrams rendered natively.
• Version history with diffs and automatic backups.
• Optional AI, either local through Ollama or with your own API key.
• Obsidian import and an external .md viewer.

Appearance

Built-in themes or your own, with configurable accents and fonts, and interface scaling from 80% to 200%.

Platforms

The mobile app opens the same Markdown vault without creating an account, and includes the editor, Tasks, Graph, and Daily Notes views.

On Linux specifically, the site lists an AppImage, an RPM for Fedora 43+, an AppImage build for Arch and openSUSE Tumbleweed, and distro packages for Fedora and Debian. The current release shown is v1.3.6.

What HelixNotes isn't

This is the clearest way to decide whether it fits:

• Not a hosted workspace. There's no HelixNotes cloud.
• Not a team collaboration suite. No shared team space is offered.
• No account required. Nothing to sign up for.

If your need is a shared, always-synced team wiki with permissions and comments, HelixNotes is the wrong tool. If your need is a personal notes app where the files stay yours and you're willing to own the sync setup, it's built precisely for that.

How to decide

Choose HelixNotes if:

• You want your notes as plain .md files you can read and move without the app.
• You're comfortable setting up your own sync (for example WebDAV) or syncing the folder yourself.
• You want rich editing — tables, math, diagrams, tasks — without a proprietary format.
• You want an open-source app on desktop and mobile with no account.

Look elsewhere if:

• You need real-time collaboration or a hosted team workspace.
• You don't want to manage sync or backups yourself.
• You need a service that guarantees multi-device sync out of the box.

Getting started

Download from the HelixNotes site for your platform, point it at a folder to use as your vault, and start writing — no sign-up step exists. If you already have an Obsidian vault, the built-in import lets you bring it over. From there, the practical setup work is deciding how that folder gets synced and backed up, since that part is intentionally left to you.
