Run open models locally — chat, code, search, vision, image generation, audio, translation, and background agents — with nothing sent to Nimbus servers for inference. Gale (chat) is free forever. Download models from Hugging Face, attach photos and PDFs, and stream replies entirely on your device. Nimbus8 Pro (one-time in-app purchase) unlocks: • Cirrus — repo-aware coding agent with inline diffs • Ashe — confirm-first background agents and scheduled Hands • Mist — hybrid local search with optional web layer • Mirage — on-device image generation • Stratus — camera, OCR, and vision Q&A • Overture — speech-to-text, text-to-speech, and audio tools • Zephyr — on-device translation • Haze — cross-module memory and recall Built native in Swift with a Rust core. No Nimbus account required. Optional cloud inference. No telemetry. Models you choose are downloaded to your device and run locally. Processing stays on your phone unless you explicitly enable optional network features (such as web search or a BYOK cloud provider in Cirrus). Purchase Nimbus8 Pro once through Apple In-App Purchase. Restore anytime with your Apple ID. Family Sharing follows Apple's IAP rules. Privacy policy: https://trynimbus.org/privacy.html
MarkWrite

WYSIWYG Markdown editor that allows embedding pictures and natural language mathematics. MarkWrite is a fast, focused Markdown editor for Mac, iPad and iPhone. Your writing formats itself as you type — headings, bold, lists, quotes, tables and code appear the moment you write them, while the Markdown syntax stays visible only on the line you are editing. Nothing to toggle, no split screen required. EMBED IMAGES, NOT LINKS Drag a picture into your document and it is really there. Grab its corner to resize it and MarkWrite writes the new size back into the Markdown for you. Text and images are saved together in one self-contained document you can move, rename, duplicate or send without leaving a single broken link behind. Images can be embedded in any of the common formats: VS Code, Pandoc or HTML. WRITE EQUATIONS BY DESCRIBING THEM Say what you mean: "x equals minus b, plus or minus the square root of b squared minus four a c, all over two a." MarkWrite turns that sentence into a properly typeset formula. There is no LaTeX to memorise — though you can type LaTeX directly whenever you would rather. Powered by on-device Apple Intelligence; requires a supported device. ALSO • Tables that line up in the editor, not only in the preview • Live preview that follows your cursor, side by side or full width • Themes: fonts, colours, spacing, line height, list spacing — saved as presets • Callouts, footnotes, highlights, code blocks and inline code • Export to PDF or print, with your theme applied • Open a whole folder in tabs and work across files • Find and replace, including regular expressions STILL JUST MARKDOWN MarkWrite writes ordinary .md files. Nothing is trapped in a proprietary format, nothing is locked in a cloud, and nothing you have written is ever held behind a subscription. Open your work in any other editor, any time, or share it with anyone and they will be able to open it with any Markdown viewer, including the embedded images.
