LucidMark

Your lightweight, local-first Markdown workspace. Seamlessly capture ideas, manage Kanban tasks, and read EPUBs or PDFs in one private, distraction-free environment.

LucidMark is a lightweight, local-first Markdown workspace designed for capturing ideas, writing, reading, organizing tasks, and retrieving knowledge. Built on the philosophy of plain text integrity, your Markdown files remain the canonical user data, while LucidMark provides powerful live projections over those files.

Operate directly on your existing files and folders without being forced to import them into a proprietary database.

Core Features (Free):

• Zero-Friction Capture: Launch quickly into a dedicated Inbox/Scratchpad to capture ideas instantly.
• Source & Visual Editing: Toggle seamlessly between CodeMirror Source and Tiptap Visual editing modes. Supports rich Markdown syntax including Mermaid, PlantUML, MathLive/KaTeX formulas, and chemistry notation.
• Kanban & Task Management: Standard Markdown checkboxes automatically power interactive Kanban boards, including Section, Tag, and Query boards. Stay organized with Today and Agenda projections.
• Universal Reader: A distraction-free reading surface for Markdown, TXT, EPUB, and PDF files. Save reader highlights and annotations directly back to your Markdown knowledge base.
• Local Transfer: Send and receive files across devices on your local network without relying on cloud dependencies.
• Web Clipper: Capture webpages and articles directly to clean Markdown.

LucidMark Pro (One-Time Purchase): Unlock the full capabilities of your workspace with a one-time upgrade to LucidMark Pro.

• iCloud Sync: Unlocks the iCloud workspace mode to safely and automatically synchronize your documents across your Mac, iPhone, and iPad.
• AI Integration: Unlocks AI execution, allowing you to configure and connect supported AI providers to act as a workspace assistant for rewriting, summarizing, and extracting tasks.

Take control of your knowledge with a workspace that respects your files and your privacy.
