OMN-Go is a self-hosted, Markdown-based personal wiki and notes app. It runs a small local web server on your device and serves your notes through a browser-style interface - no account, no cloud service, and no dependency on any third party to keep working.
Notes are plain Markdown files with a small metadata header (title, date, tags), compiled to static HTML pages you can browse and link between using ordinary relative or absolute links.
Key features:
* Full Markdown editing, with an internal editor or your preferred external text editor.
* Optional git synchronization over SSH, so the same notes stay up to date across every device you run OMN-Go on. Conflicts are shown clearly, with manual-merge and safe pull/push options.
* Optional LAN sharing: off by default (the app only answers itself); when enabled, other devices on your network can reach your notes over HTTP with a password, useful for reading or editing from a second device without setting up sync.
* An embedded SQL database that note scripts can read and write directly, with on-demand, git-trackable snapshots of its contents saved alongside your notes.
* Quick capture: a one-tap quick-note box and a bookmark collector, including Android share-to-app support.
* An automatically generated Tags page that indexes every note by its tags and works offline.
* On Android, notes can open system settings screens, launch other apps, or run Termux commands through intent: links - 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 you can drop into any note.
OMN-Go also runs on the desktop. Linux and Windows builds are available at https://github.com/mvbasov/OMN-Go/releases - the same notes and the same interface, with optional git sync keeping a computer 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.

OMN-Go does not include ads, analytics, or trackers of any kind, and does not require an internet connection for day-to-day note-taking - sync and LAN sharing are both entirely optional.
AI coding assistants have been actively used in this app's development - for implementation, refactoring, and drafting supporting documentation such as this listing - alongside human review and direction.
