Autofill Vault: Store Your Details Once, Fill Them AnywhereAutofillVault

Autofill Vault stores your details once and copies or fills them anywhere. A full-page dashboard organises everything into categories (Personal, Address, Education, Professional, plus any you add) with a copy button on every field. A toolbar popup offers "Fill this page," shows accounts saved for the current site, and has a quick search-and-copy box. It is simple and local by design.

A shared data model and field-type dictionary back both the dashboard (rename, reorder and extend categories, with inline editing) and the popup. The autofill engine injects into the page, detects fields, and fills them by matching names, labels and autocomplete hints, flashing each filled field blue. It also works on React and Vue forms, and Alt+Shift+F fills the whole page. JSON export/import keeps the vault portable. It is plain HTML/CSS/JS with no build step: edit a file and hit Reload.

Filling the same forms over and over mostly goes away, whether triggered from the popup, a keyboard shortcut or right-click. It is the simpler predecessor of ApplyOS, and the project that convinced me to handle passwords properly the next time.

By design it stores data, including passwords, unencrypted in chrome.storage.local. That is fine for convenience but it is not a substitute for a password manager. That limitation is what pushed me to build ApplyOS's AES-256-GCM credential vault.
