02·The moment

Most thoughts evaporate before you can save them.

Capture turns one tap into a permanent home for anything you read, watch, hear, or think.

One tap. From a phone in line at the pharmacy to a permanent row in the captures table.

Captured · One tap
03·The mechanism

A one-tap capture tool. From anywhere to a permanent home.

Three files. That is the whole system.

i. SQL
A nine-column captures table.
schema.sql · Supabase · RLS on
ii. JS
Thirty-six lines of vanilla JS.
bookmarklet.js · Chrome bookmarks bar · One click
iii. iOS
Three actions in the Shortcuts app.
share-to-capture · iOS share sheet · One tap
04·The receipt

Capture cost approaches zero.

One click on the desktop. One tap on the phone. An optional one-line note. That is the whole interaction.

36
Lines of vanilla JavaScript in the desktop bookmarklet. It captures the selected text and the page URL, asks for an optional note, and posts one row to Supabase.
05·The system

The first move in a longer chain.

Capture is the input layer. The rest is the writing system.

01 · Input
Capture
One tap, anywhere. This page.
02 · Record
Supabase
One table holds every capture, permanently.
03 · Review
A tagging pass
Captures get read, tagged, and connected.
04 · Output
The writing
The strongest captures seed finished pieces.

Before Capture, writing started at a blank page. Now it starts where the reading happens. On a phone, in line at the pharmacy.

The smallest build on the list, in daily use.
