A local tool I built with Claude Code that finds the payments on my company's bank account that miss a receipt, matches each one with invoice files I already have, and uploads them only after I approve every match.

A native Mac recorder with OBS-style scenes: 1 Stream Deck key sets up the screen, the camera and the mic, and records. It replaces OBS, which I used for more than 10 years, and my agents can drive every part of it. Built with Claude Code.

Press 1 button on the scanner and the page ends up OCR'd, named, filed and searchable. OCR and the AI run locally on my Mac, so nothing leaves the house.

When a person is detected outside, a window opens on my Mac with the live camera stream and the latest clips. It shows in about 1 s, where the old web app took 10 to 20 s.

My own menu bar app, replacing Bartender. 1 button or ⌃⌥⌘M lists every menu bar icon with its image, name and state, opens any icon's menu, and keeps all the other icons out of sight.

A native menu bar app I built with Claude Code to replace CleanShot X: 1 key for a window, a display or an area, the frozen screen up in about 56 ms, the file on disk 21 ms after the click.

A native macOS text expander that replaced Espanso: Markdown snippet files, a search panel, 30 MB of memory instead of 350 MB. Built and switched over in 1 day.

A native rules engine I built with Claude Code to replace Hazel. It renames, moves and runs scripts on new files, never deletes, and can undo every move.

A native macOS sticky note in my NicAI design. 1 to-do list on the screen, fed from my iPhone through iCloud Drive, full screen on all 4 monitors with 1 click.

A native macOS viewer and light editor for SQLite and CSV that replaced TablePlus and Easy CSV Editor: a 624,000-row table on screen in 352 ms, in a 2.6 MB app.

A native text editor that replaces TextMate as my clipboard scratchpad. Against TextMate, CotEditor, Sublime Text and TextEdit, it wins 12 of 16 speed and memory measures.

A tiling window manager I built in 1 day with Claude Code, in Lua inside Hammerspoon. It replaces Amethyst and tiles a new window in 0.1 s instead of 9 s.

A native Mac app that keys my green wall in real time, follows the daylight all day, keeps me solid even with green on my glasses, and shows up in any call app as a camera called Webcamee. It replaces the ATEM Mini on my desk. Built with Claude Code.

Every app I built for myself with Claude Code, what each one does, the app it replaced, and a link to its full note.

A native Mac app I had my AI agent build to replace Pulltube. 1 hotkey downloads the video in my browser tab, 2x faster than Pulltube, with 8x less memory.

How I make Claude's replies to me easy to read: ASD-STE100 softened to 80%, Google's developer style, Zinsser, and a precedence order.

A local dashboard on port 9000 that starts, stops and opens every browser app under ~/ai. Fixed ports, start on click, 1 file of stdlib Python.

How I configure Claude Code for NicAI: layered CLAUDE.md files, hooks, auto-memory, permissions, skills, connectors and the output conventions.

What NicAI has cost me in time and services, what failed on the way, and the lessons I would give anyone building their own AI layer.

Why SQLite files, Markdown knowledge bases and JSON are the source of truth for NicAI, and the 4 nightly jobs that keep them current.

My personal AI layer: what it is, why I am building it, how it started in 2022, and where it stands in September 2026.

NicAI Lab, the site where NicAI and I put the pages, demos and files we build, shared through unlisted links that only work if I give them out.

How NicAI turns "write a note about X" into a live, signed page on this site in about 15 seconds: the write-note skill, the publish hook and the 5 publish phases.

The 30 small Python wrappers my NicAI skills call for research, web data, media, publishing, email, DNS and home automation, and the pattern they share.

Every skill in my NicAI setup, grouped by purpose, 1 line each, plus what a skill is and the rules I build them by.
