TOOLS
Open-source tools
Open-source tools I've built, plus a method I've released openly. All free, no account required, and nothing you enter reaches my server.
Each one started because I ran into a problem myself and couldn't find something that already solved it.

LiveWhich stages AI can take, and which it can't
Breaks writing into 8 stages and marks which ones AI can take and which need your own judgment. Download the zip and upload it to claude.ai (Pro plan with Code execution enabled), then work entirely in the browser — no coding. What comes out is not just an article but a fact-check table and citation list alongside it. CC BY 4.0, and it works the same in any other field.
TimeTracker
Source only, self-hostedBuilt for my own freelance work
Log billable hours, calculate monthly invoices, and track annual revenue goals. Data stays on your own computer. No cloud, no account.
These are things I built because I ran into the problem myself. If your organization has one it wants built too, let's talk.
