Each tool is a small repeated job we got tired of doing badly somewhere else. We build them the way we build client work, fast, local-first, no account walls, and leave them out on the bench.
Everything runs in your browser. No uploads, no tracking pixels, nothing phoning home. If one saves you ten minutes a week, that's the whole business model: you'll remember who built it.
