Markor is an open-source, Local-First text editor for the Android platform designed for privacy and cross-platform document interoperability. The solution operates entirely offline, managing plain-text files directly on the device's filesystem without reliance on proprietary cloud services or centralized databases.

Key Capabilities

Multi-Format Markup Support: Natively supports and renders multiple plain-text standards, including Markdown, todo.txt, and Org-mode, alongside support for Zim/WikiText, AsciiDoc, and structured formats like YAML and JSON.
Specialized Task Management: Features a dedicated todo.txt editor mode with context-sensitive action buttons for managing priorities, project tags (+), and contexts (@), as well as an automated archiving mechanism for completed tasks.
Workflow Shortcuts: Provides "QuickNote" and "To-Do" interfaces for rapid data capture, accessible via swipe gestures, widgets, and Android launcher shortcuts.
Geospatial and Math Integration: Supports KaTeX for mathematical formula rendering and allows for the insertion of timestamps and GPS coordinates directly into the text stream.
Zero-Telemetry Privacy Model: The application contains no ads, tracking, or telemetry. It adheres to a strict privacy model where internet access is only utilized for user-initiated content retrieval (e.g., loading external image assets).
Filesystem Synchronization Compatibility: Because it operates on standard file directories, the platform is natively compatible with third-party synchronization tools such as Syncthing, Nextcloud, and Git clients.

Audience: Developers, privacy-conscious professionals, and users requiring a mobile-to-desktop bridge for text-based knowledge management.
