NanoMouse is a Rime keyboard and BytePaste workspace built for AI input. It saves common prompts, snippets, materials and clipboard content, then syncs them across iPhone, iPad, Mac and the keyboard extension under the same iCloud account. For AI chat, writing, coding and research, input is more than typing. You often need role settings, output formats, frequent phrases, images, Markdown, canvas sketches, causal graphs or quick voice notes. NanoMouse keeps those materials close to the keyboard. Key features: - Rime keyboard: Wusong Pinyin, double pinyin, Japanese romaji, stroke input and more. - Pinyin shortcuts: easier rules such as `ng -> nn` and `uan/uang -> vn/vnn`. - Mixed Chinese, Japanese and English input with quick switching. - Long-press letters for extended characters, and long-press `123` for the number keypad. - Keyboard toolbar for voice input, canvas, Markdown and BytePaste. - AI workflow: store prompts, role settings, output templates, high-frequency text and code snippets in BytePaste. - Multi-type cells: plain text, rich text, links, colors, images, camera, photo library, PDF, files, Markdown and canvas files. - iCloud sync for cells and previews across devices signed in to the same iCloud account. - Clipboard history: copy on Mac, reuse on iPhone, iPad or the keyboard extension. - Voice input for capturing quick thoughts before turning them into AI-ready text. - Markdown workspace with live preview, Mermaid diagrams and HTML color rendering. - Canvas and causal graphs for expressing structure visually. - macOS configuration tool for managing Squirrel/Rime settings without hand-editing YAML. AI input and BytePaste are useful for: - Pasting common prompts, system prompts, role settings and output formats with one tap. - Reusing frequent phrases, canned replies, signatures, templates, code snippets and links. - Keeping images, files or Markdown in fixed cells and continuing on another device. - Recording ideas with voice, organizing context in Markdown, and expressing structure with canvas or causal graphs. - Opening common materials inside the keyboard instead of switching between the current app and Files. - Copying content on Mac and reusing it from the keyboard on iPhone or iPad. Basic usage: - In the main app or on Mac, open BytePaste and place common prompts, frequent phrases, rich text, images, files, Markdown, canvas files or causal graphs into cells. - In any text field, switch to the NanoMouse keyboard and tap the BytePaste button in the toolbar. - Plain text and prompts can be inserted by tapping a cell. - Rich text, images, files, Markdown and canvas content are limited by the system keyboard environment. Usually, long press a cell, choose copy, preview, export or the matching action, then paste or insert it in the target app. - Clipboard content copied on Mac can enter clipboard history and later be reused on iPhone, iPad or in the keyboard extension. Long-press tips: - Long press letters for extended characters. - Long press `123` for the number keypad. - Long press the language key to switch Chinese, Japanese and English input. - Long press the candidate bar to switch between Simplified and Traditional Chinese. - Long press or right-click a BytePaste cell to edit text, copy from clipboard, set as file, take a photo, choose from photo library, copy to clipboard or clear it. NanoMouse respects system permissions and data boundaries. Voice, location, camera, photos and iCloud capabilities are used only when needed. BytePaste sync uses your private iCloud database and syncs only between devices signed in to the same iCloud account. If you like Rime configurability and want less switching between typing, pasting, voice, drawing, Markdown and causal graphs before talking to AI, NanoMouse fits that workflow.
