CopyBox

Read full description

CopyBox is a clipboard library and keyboard paste tool for iPhone. Save copied text, reusable snippets, links, and replies, then paste them from the CopyBox keyboard without switching back and forth between apps. Input Templates turn a reusable message into a simple fill-in form. Define fields such as Customer Name, enter their values when you use the template, review the completed message, and prepare it for the CopyBox keyboard. Only the completed text is available to the keyboard, and it expires automatically after 30 minutes. Use CopyBox for common replies, support messages, links, hashtags, and any text you need to reuse. When several messages must be sent in a specific order, Queue mode lets you paste the next saved item one step at a time. Key features: - Create Input Templates with your own field names - Enter values, preview the completed message, and prepare it for the keyboard - Save current clipboard text from the main app - Save selected text and URLs from the Share Sheet - Keep recent clips and saved snippets ready - Keep multiple snippets in an ordered queue - Create, rename, and delete queues for different tasks - Insert recent clips, saved snippets, prepared templates, or the next queue item from the custom keyboard - Import multiple lines at once - Mark snippets as used and reset queue progress when needed - Use Shortcuts actions to save the clipboard, add text, copy the next clip, reset queue progress, and open the app CopyBox stores snippets, templates, and prepared text locally in its shared App Group container. Clipboard text, keyboard input, snippets, template fields and values, and completed messages are not sent to a developer server or included in data sent to advertising, Analytics, or Crashlytics services.
