COA Research — small tools, built by hand

Small tools, lighter days.

Orqnote, a Mac dictation app. NagiShield, a WordPress defence plugin. Both started as annoyances I decided to fix myself.

The tools

Both started with a problem of my own.

01 Mac app

Orqnote

Speak, and the writing is done.

An AI notes app that transcribes and tidies your words entirely on your Mac. Less typing, more thinking.

The meeting tomorrow at 10 works for me.

About

Who makes this.

COA Research is the name I build under, on my own. Dictation for the Mac, defence for WordPress, and a journal about food and health. If something is annoying enough, it gets made into a tool.

  1. 01

    Build

    If it is awkward, build the thing that fixes it.

  2. 02

    Protect

    Keep what we built running quietly in the background.

  3. 03

    Write

    Record what the research and the building taught me.
