Rho MD: Markdown Reader
Notes & knowledge base
Free · In‑App Purchases
One beautiful, powerful home for your notes: read, edit in place, build a linked library, time your work with focus stats, and ask Rho AI. Local-first.
Rho MD is more than a Markdown app. It is one beautiful, powerful place to read, write, organize what you know, manage your time and think with an AI assistant — local-first, with every note a plain file on your device.
READ
• Book-quality typography for .md, .mdx and .markdown files, in light or dark
• Flowcharts, math, tables, code with syntax highlighting, and live interactive charts
• Book layout for long documents: read by pages, not one endless scroll
• Highlight as you read; bookmarks and an outline keep your place
WRITE
• Click any paragraph and type: the document itself is the editor
• Formulas, footnotes and images stay intact while you edit
• Switch to the Markdown source at any time
• Free-form canvas boards for visual thinking, saved as plain Markdown
ORGANIZE YOUR KNOWLEDGE
• Psi, the built-in library: every note in one place, grouped into constellations
• Psi Star Map: your notes as stars, your links as the lines between them
• Links between notes, tags, daily notes and full-text search
• A home page with today's note, your focus and your recent files
MANAGE YOUR TIME
• A Pomodoro timer and a stopwatch, with a button for each thing you work on
• A daily goal for each activity, and today's progress at a glance
• A statistics dashboard: focus by day, month and year, the notes you created and edited, your diary streak
• A calendar where every day shows its focus time, notes and diary
AI ASSISTANT
• Ask Rho AI about your own library; answers point back to your notes
• Research reports with numbered sources that have been checked
• Turn web pages, Word and PDF files into clean Markdown notes
• Before your first message, Rho AI shows what will leave your device
LOCAL-FIRST
• Your notes are plain Markdown files in folders you choose — nothing is locked in
• Rho MD works fully without an account, and your library stays on your device
• An optional rho.md account adds cloud backup and private sharing for free; a subscription adds sync for the folders you choose across your devices, publishing to Discover and Rho AI. Subscriptions are offered as in-app purchases.
ACCESSIBILITY
• Screen reader labels, full keyboard control, and respect for Reduce Motion and Increase Contrast
Discover is a feed of documents the community publishes; you can report any document and block its author.
Available in English, Simplified Chinese, Traditional Chinese and Japanese.
