nexusStack vs XSIME

Meet .nexusStack, a focused workspace for everything around a job, client, project or personal goal. Each one gets its own stack, with deliverables, checklists, notes, mind maps, repos and links, so nothing gets mixed up. STAY ON TOP OF THE WORK Track deliverables with due dates and reminders, and see what's overdue at a glance. Sort to-dos into Now, Next and Later, then clear them one at a time in Focus mode. CAPTURE EVERYTHING Write rich notes, and keep files, photos, scanned documents and links on the same board. Text recognition makes it all searchable, and any note or file can become tasks in a tap. THINK VISUALLY Map ideas on a fluid, zoomable canvas. Choose a layout, switch to an outline, send ideas to your task lists, present branch by branch, and export to PDF, PNG, Markdown or OPML. KNOW WHERE THINGS STAND Each stack shows its insights at a glance: completions, on-time rate, streaks and recent activity, plus details tailored to the stack type. KEEP CODE AND DOCS CLOSE Browse GitHub repos, branches and files from any stack, and sign in to see your private repos. Save Confluence links per stack. Repo Pro (optional in-app purchase) adds syntax highlighting, search, bookmarks, rendered Markdown, diffs and blame. MADE FOR EVERY SCREEN Designed for iPhone, iPad and iPhone Duo, with home screen and Lock Screen widgets and an optional Liquid Glass look. MAKE IT YOURS Use the clean default theme, or choose Midnight Neon, Aurora, Prism or Obsidian (optional in-app purchases). PRIVATE BY DESIGN Your data stays on your device. No account required. BUILT FOR • Freelancers and contractors juggling multiple clients • Team leads coordinating deliverables across projects • Engineers, PMs and tech pros who want notes, tasks and repos side by side

XSIME is a keyboard and text assistant for your iPhone, formerly RIMES / Lingxi IME. Type locally, organize your words in Buffer, and choose optional translation or AI assistance when you need it. TYPE YOUR WAY Use Pinyin, nine-key Pinyin, Ziranma double Pinyin, Wubi 86, XSIME Wubi, English or slide chords. Switch Simplified and Traditional Chinese, customize key layouts, and import compatible Rime scheme ZIPs or coded UTF-8 text dictionaries. XSIME Wubi combines Wubi and Pinyin; Wubi 86 offers z-prefixed Pinyin lookup. Both Wubi schemes can commit a unique four-key Wubi match automatically. A BUFFER FOR YOUR WORDS Compose and edit before inserting text into your app. Tap to insert one block, or hold for one second to insert all remaining blocks. Default Buffer also offers optional timed insertion, off by default; translation and AI results require explicit insertion. Inserting text never sends a message for you. Explicitly import readable text from the current input field, or collect clipboard text with the system Paste control. Saved clipboard entries stay in a separate local history that you can delete or clear; opening the list does not read the system clipboard. OPTIONAL APPLE TRANSLATION On iOS 26 or later, Apple translation uses downloaded on-device language models. Prepare the required languages in the XSIME app, then choose a language pair in Buffer. Availability depends on supported languages and downloaded models. No external AI fallback is used when local translation is unavailable. YOUR CHOICE OF EXTERNAL AI For optional AI polishing, rewriting and other writing tools, configure your own HTTPS AI service that supports a general-purpose interface format, along with your model and API key. The recipient is shown before you grant permission. Only Buffer text you explicitly submit is sent to the configured, consented service. Your provider's data policy applies and its service may require a separate account or payment. XSIME does not include an AI subscription, provider credentials or a hosted AI service. PERSONALIZE YOUR KEYBOARD Manage built-in Buffer tools, keyboard appearance, custom chord mappings and status-light pets. View local typing statistics and create a statistics card. Local learned associations suggest what you may want to type next. LOCAL EVERYDAY INPUT Ordinary typing and Buffer editing work offline without Full Access, an app account or a subscription. XSIME has no ads or keyboard-text telemetry. API keys use this device's Keychain. External AI, collecting clipboard text from the keyboard and keyboard image export require Full Access; saving an image to Photos requests add-only photo access. Buffer drafts are cleared when the keyboard session ends; separately saved clipboard history, learned words and settings remain on the device. Enable XSIME in Settings > General > Keyboard > Keyboards, then choose it with the globe key. Secure fields and apps that prohibit third-party keyboards use the system keyboard. Requires an iPhone running iOS 17 or later. Apple local translation requires iOS 26 or later and supported language models. Haptics depend on device and system settings.
