Vowkey reads your passport, ID, and documents once — alongside your logins, cards, and API keys — then fills every field across websites, PDFs, Word, Excel, and AI.
@vk:…, and Vowkey writes the real values locally.
Sensitive numbers stay masked until you need them. Click Fill on any form yourself, or approve in one click when an AI agent asks to fill a field.
In 1Password, saving a passport or ID means typing each field into a blank template — while attached scans sit unread until you open and copy from them yourself.
Vowkey reads documents on your computer and verifies MRZ check digits automatically. Every saved detail links back to its blue highlight on the original scan.
Inline browser menus handle username, password, and basic contact inputs, but stop at split character boxes, imperial era dates (平成10年), half-width Katakana (ｸﾞｴﾝ ﾃｲ ﾘﾝ), or Excel, Word, and PDF files.
Vowkey formats dates (YYYY-MM-DD, DD/MM/YYYY, 和暦), uppercase names, character grids, and half-width Katakana across websites, PDFs, Word docs, and Excel sheets.

Quick Access is designed for copying values yourself, with no way for Claude Code or Codex to fill a sensitive field without seeing the value.
Each detail has its own rule (Fill without asking, Ask first, or Don’t fill). When Claude Code needs a pension or ID number, Vowkey pauses for your click on Allow once.

Claude, Codex, or another AI agent can ask Vowkey to fill by reference. Vowkey's tools return what was filled, not your saved values.
Opening Vowkey on your computer registers your local agent host automatically. Claude Desktop, Claude Code, Codex, and Cursor connect without manual tokens.
Your AI agent inspects blank form labels and maps @vk: references across up to 200 fields at once. Vowkey writes the real details on your device.
Coding agents sync @vk: templates and run commands through vowkey run so raw keys stay out of prompts and terminal logs.

@vk: Preview
Even when a form is only a phone photo of a printed sheet on a desk, your AI agent maps the blank boxes to @vk: handles and Vowkey places each character cleanly into the grid.
Documents are read on your computer by default.
Passports, IDs, PDFs, and spreadsheets are read directly on your Mac or PC. Nothing leaves your computer when reading a document or filling a form.
