CA3 is your personal AI memory workspace on iPhone. Use the app to read, search, and manage the notes stored in your CA3 workspace. Notes can include Markdown content, source metadata, publishing state, revision history, and attachments. CA3 also includes iOS integrations for capturing useful context while you work: - Save text, links, screenshots, or a photo from other apps with the CA3 Share Extension. - Extract text from a shared image on device and keep it with the image in one searchable note. - Clip Safari pages with the bundled Safari extension. - Preview extracted page content before saving. - Save source URL, title, site metadata, Markdown body, and selected page images. - Open and review saved notes in the CA3 app. - Sign in with CA3 OAuth using scoped access. CA3 is designed for user-owned memory. It does not automatically read browsing content or photos in the background. Safari page content is accessed only when you open the extension or use one of its clipping actions, and shared content is processed only when you invoke the share sheet. Text recognition for a shared image runs on device; the image and resulting note are uploaded to your CA3 workspace only after you tap Save.
