Most note apps ask you to make an account before you can write a single sentence, then sync that sentence to a server you did not ask for.
But a large share of what people actually type is temporary: a phone number held for thirty seconds, a paragraph being reworded, text pasted somewhere neutral to strip its formatting. That work does not need an account, a sync engine, or a subscription. It needs a blank page that opens instantly.
Opening the app puts you in an empty note with the caret already in it. Earlier notes wait in the sidebar, and a note you leave empty is discarded rather than cluttering the list.
Everything is stored in your own browser. Nothing is uploaded, nothing is synced, and there is no account to make.
Rich text with headings, lists, and checklists. Starring, and sorting by date, name, or starred. Font and text-size choices for the editor. An opt-in auto-delete after thirty days that never touches a starred note. Sanitized paste, rich copy that keeps formatting, export, word count, and full light and dark themes.
Designed in Claude Design and built with Claude Code as a single HTML file with no build step, which is the right shape for something this small.
The handoff documents the tradeoffs rather than hiding them: the editor uses a deprecated but universally supported browser API because adopting a full editor framework would have been disproportionate, and browser storage caps around five megabytes, which is roughly a million words of plain text.
Tags, folders, sharing, sync, and multi-select were all considered and left out. Each one is individually reasonable and each one turns a scratchpad into an application that needs maintaining, which is the opposite of the point.
Pasted content is sanitized to a deliberate allowlist of tags, with every attribute stripped except safe links, so text pulled in from anywhere on the web cannot bring anything with it.
