Type it once. Tap it forever. Keyboard Clipboard is a text expander keyboard for the things you type again and again: addresses, emails, phone numbers, links, bank details and ID numbers. NEW IN 2.0: SMART IMPORT Paste an email signature, a booking confirmation or a contact card and Smart Import pulls out every email, phone number, link, address and reference number, ready to save as snippets. On devices with Apple Intelligence, on-device AI gives each one a sensible name. On every other device, quick detection does the job offline. Nothing you paste leaves your device. HOW IT WORKS 1. Save your snippets in the app, by hand or with Smart Import. 2. Turn on the Keyboard Clipboard keyboard in Settings and allow Full Access so it can read the snippets you saved. 3. In any app, switch to the keyboard and tap a snippet to type it. FEATURES • One-tap snippets in any app, color-coded and labelled (Address, Document, Link). • Pinned favorites stay at the front of the keyboard. • Filter the keyboard by label, and make the keys bigger or smaller. • Siri and Shortcuts: copy a snippet, add a new one or run Smart Import by voice or from the Shortcuts app. Snippet names show up in Spotlight. • Try the keyboard inside the app before you use it for real. • A distinctive hand-drawn design, with full light and dark mode support. PRIVACY Your snippets are stored on your device, in a container shared only with the Keyboard Clipboard keyboard. The keyboard has no network code and never records or sends what you type. Full Access is needed only so the keyboard can read the snippets you saved in the app. Terms of use: https://doc-hosting.flycricket.io/docukeys-terms-of-use/635916ce-768c-4705-9e94-a7496126e7ee/terms
