Write in local Markdown. Think with AI when you choose. Keep standard .md files, organize knowledge, and discuss the document in front of you.
marknow is a native Markdown editor for macOS, designed for long-form writing, knowledge organization, and focused thinking.
Your notes are standard .md files in local folders you choose. Open them with any editor, manage them with iCloud or Git, and keep them free from proprietary formats.
LOCAL-FIRST BY DESIGN
• Use any local folder as a Vault
• Keep standard Markdown source files
• Organize files and folders the way you already work
• Your notes are not stored on marknow servers
A CALM, NATIVE WRITING SPACE
• Native macOS editing experience
• Live Markdown styling for long documents
• Table of contents navigation
• Tasks, images, links, code blocks, and Mermaid diagrams
• Favorites and flexible file sorting
AI THAT WORKS WITH YOUR DOCUMENT
• Discuss the current note without repeatedly copying the full text
• Select text to ask questions, revise, rewrite, continue, or translate
• Insert useful sections back into your note with undo support
• Analyze images and use a separately configured image model
BRING YOUR OWN MODEL
Choose Google Gemini, OpenAI, Xiaomi MiMo, Anthropic Claude, or an OpenAI-compatible service. Chat and image-generation models can be configured separately.
LOCAL MEMORY LIBRARY
When enabled, marknow indexes selected Markdown notes on your Mac and retrieves relevant passages as context. Indexing and retrieval stay local and do not require extra API calls.
A PARTNER YOU CAN SHAPE
Set the assistant’s name, how it addresses you, collaboration style, and long-term visual identity. Persistent changes are saved only after you confirm them.
PRIVACY AND CONTROL
API keys are stored in the macOS Keychain. Content needed for an AI request is sent only when you start that request, and only to the provider you selected.
Start with one Markdown file. Keep your writing, knowledge, and workflow in your own hands.
