OMN-Go is a self-hosted personal wiki and note application that uses Markdown. It runs a small local web server on your device and shows your notes in a browser-style interface. It needs no account, no cloud service, and no third party to keep working.

A note is a plain Markdown file with a small header block (title, date, tags). OMN-Go compiles each note to a static HTML page. You can read these pages and link between them with ordinary relative or absolute links.

Key features:

• Full Markdown editing, with the built-in editor or your preferred external text editor.
• Optional git synchronization over SSH, so the same notes stay up to date on every device that runs OMN-Go. OMN-Go shows each conflict clearly and gives you a manual merge or a safe pull or push.
• Optional LAN sharing, off by default. In the default state, OMN-Go answers only local connections. If you enable LAN sharing, other devices on your network can reach your notes over HTTP with a password. This is useful to read or edit from a second device without git synchronization.
• An embedded SQL database that note scripts can read and write directly. You can create a backup of its contents at any time. Git can track this backup, and OMN-Go saves it with your notes.
• Quick capture: a quick-note box that opens with one press, and a bookmark collector. Both work with the Android share-to-application function.
• The Tags page, which OMN-Go generates automatically. It indexes every note by its tags and works offline.
• On Android, a note can open a system settings screen or start another application. It can also run a Termux command. These links use an intent: URI, and the function is off by default.
• Math formulas (KaTeX, opt-in per page) and automatic syntax highlighting for fenced code blocks.
• Light, dark, and system-following themes.
• Material Design icons and small HTML/JS building blocks that you can put into any note.

OMN-Go also runs on the desktop. You can get the Linux and Windows builds at https://github.com/mvbasov/OMN-Go/releases - the same notes and the same interface. Optional git synchronization keeps a desktop device and a phone in step.

I tried to describe as much as possible in the built-in documentation. Please read it.

I design this application to my needs and use it everyday for several years. I will be glad if this application meets anybody needs also.

This Telegram channel shares news and usage tips for OMN-Go: https://t.me/OMNNewsAndTips

OMN-Go does not include ads, analytics, or trackers of any kind. It does not need an internet connection for day-to-day work with your notes. Git synchronization and LAN sharing are both optional.

OMN-Go installs on Android 6.0 and newer. The limit is the WebView and not the version of Android: OMN-Go needs a System WebView of Chromium 85 or newer. Android 6 ships Chromium 44, which is too old, but the "Android System WebView" component updates to Chromium 106 on that release. Update that component and Chrome first. When the WebView is too old, OMN-Go shows a line at the top of the page that names the version it found and the version it needs.

AI coding assistants did much of the development work on OMN-Go. They wrote code, refactored it, and drafted supporting documentation such as this listing. A human reviewed and directed this work.
