Vox.md is a local-first quick capture app for Obsidian vaults and Markdown folders. Send text, links, photos, files, document scans, sketches, and voice to the right note without stopping to organize first. CAPTURE MORE THAN VOICE Add typed Markdown, a URL, photos or screenshots, files, a document scanner with on-device OCR, a sketch, or a voice recording. Combine several items in one capture, preview the result, then save it as plain Markdown. SEND IT WHERE IT BELONGS Capture Presets remember the destination and formatting for workflows such as your inbox, journal, task list, or meeting notes. Create a note, append or prepend to an existing file, insert beneath a heading, or write to rolling daily, weekly, monthly, quarterly, or yearly notes. Each preset can keep its own template, metadata, attachment folder, filename rules, placement, and processing preferences. Override a destination or template for one capture without changing the preset. CAPTURE FROM MORE PLACES Use Vox.md from the app, Share Sheet, custom keyboard, Home Screen and Lock Screen widgets, Shortcuts, or Apple Watch. Pending and failed deliveries remain available for retry, so a temporary folder permission or sync issue does not lose your work. PRIVATE VOICE TRANSCRIPTION Transcribe speech into text on your device with Apple Speech, Whisper, or Parakeet, depending on your settings and device. Audio and transcripts are never sent to Vox.md servers. Use offline dictation and voice typing from the custom keyboard, record on Apple Watch, or export transcripts as TXT, Markdown, JSON, or YAML. PLAIN FILES, NO LOCK-IN Vox.md writes standard Markdown to the folders and Obsidian vaults you choose. You do not need an account or a proprietary notes database. Your files remain readable in any Markdown app. FREE TO TRY New users receive 15 minutes of free transcription and 10 successful Capture deliveries. A single one-time purchase unlocks unlimited use. There is no recurring subscription. PRIVACY Capture contents, exported notes, audio, transcripts, keystrokes, file paths, and bookmarks are not sent to Vox.md servers. Vox.md collects limited, privacy-safe onboarding analytics to understand setup problems. Microphone, camera, photo, and file access are used only when you choose those capture types.

**What is CosmoMap?** - CosmoMap is a personal knowledge map that turns pages and notes collected from Safari into stars and connections. - Save information from the Safari extension, Share Sheet, or manual entry. - Use fast full-text search as your starting point, then view and explore pages, topics, and links as a 3D knowledge map of stars and lines. - Jump from search results to a star, follow its connections, and discover unexpected relationships. **Four ways to view** - Choose from Sphere, Nebula, Neural Network, and Plane views. - Switch views to explore the same information from different perspectives. **Expand with AI** - Choose a topic, and CosmoMap creates text you can give to an AI. - Paste it into an AI you use, such as ChatGPT, Claude, or Gemini, then import the returned file or response text. → New stars and connections are added to your map. - Choose 30, 100, or 200 items to expand. - CosmoMap does not connect directly to AI services. No API key or additional payment is required. **Passcode for each notebook** - Set a different numeric passcode for every notebook. - On supported devices, you can also unlock notebooks with Face ID or Touch ID. - Keep work, study, hobbies, and other knowledge maps separate and secure. **Includes the Japan Star Map sample** - Includes a star map built from 50,000 Japan-related articles from Japanese Wikipedia and 151,153 real article links. - Start exploring a vast knowledge universe even before adding anything yourself. **Cosmic Collapse Mode** - Use the knowledge map you have grown as your stage: tear through stars, fling them away, and pull them in for a spectacular collapse. - Turn your knowledge map into a place to play, not just a place to organize and browse. - Close the mode at any time to return to your original map. Your information is never damaged. **Stored on your device** - Imported information is stored on your device. The app does not automatically send it to external servers. - AI integration works by letting you review and copy or share information yourself. - Safari Private Browsing pages are excluded from automatic capture. **About the sample data** - The included sample uses article titles and introductory excerpts from Japanese Wikipedia. - It is available under the Creative Commons Attribution-ShareAlike 4.0 International license (CC BY-SA 4.0). - Open any article’s detail screen to view its source article and edit history.
