› Snips

Type any /command, press space, and its stored text appears — in any app, in any text field.

Typing /phone and pressing space replaces the command with the stored value. The same keystroke worked in any text field on the system — browser forms, Word, Excel, a note. Recreated here; the original ran on Windows.

// the problem

Applying for jobs meant typing the same handful of facts — phone number, email, date of birth — into form after form. Windows had nothing that reliably offered them back. Browser autofill only fired on fields it happened to recognize, which was inconsistent, and the moment I was outside a browser there was no autofill at all. So every application meant pulling the same values out of my head and typing them again. I wanted one mechanism that behaved identically everywhere: define a value once, type a short command anywhere, get the value.

// approach

01The trigger is a command plus a space — type /phone, press space, and the command is replaced where it sits. The hook is a three-state machine (idle → building a command → expanded), small enough to reason about, and that third state buys a real affordance: one backspace immediately after an expansion puts /phone back. The space that fires the expansion is suppressed rather than typed and then deleted, so nothing flickers on screen.

// notes

–I wrote a far more detailed spec for V2 — a math evaluator, live data, AI summarization behind a Supabase edge function — than I ever wrote for V1, and built none of it. The planning was the fun part, which is exactly why it wasn't the useful part.
