THE WORKSPACE
• Folders saved as vaults, split into projects; notes in tabs or windows, and a pinned tab stays put while you open the rest
• Move or copy notes and files between folders, projects and vaults together with their attachments: links update by themselves, also when you rename
• Version history: every note keeps its previous versions, to compare with the current text and restore
• Search the whole vault, and the Timeline: a heatmap of the year that finds each day's notes
• Preview PDFs, images, Word documents and Excel sheets; read-only SQLite databases; Canvas in the JSON Canvas format
• .csv and .tsv files open as a table you edit in place, even large ones
• Convert images, also to WebP and AVIF; format code in many languages
• Drag a message from Mail: formatted body, attachments and images in place
• Browse and extract zip files, Finder tags, folder icons, external folders linked read-only, Terminal in the note's folder
VAULT FOR SECRETS
• Passwords, keys and private data inside the vault, encrypted and linkable to notes and projects (⇧⌘L)
• Master password or Touch ID; locks itself again. System cryptography only, no cloud
CALENDAR
• Day, Week, Month and Year views, multi-day events, CSV or XLSX export with real dates for Excel
WORD THEMES FOR DOCX
• Convert a note with your own .dotx or .docx template: the theme's styles, header, footer and fonts, {{placeholders}} filled from the note's properties
AI AGENT (bring your own key)
• Reads and edits your notes inside the app: every change is proposed as a diff and applied only after you approve it
• Also reads PDFs, Office documents and images; one chat per window, tied to the active note
• Generates properties from the content and translates the note, always with a preview
• Native Anthropic or any chat/completions endpoint; the key stays in the Keychain, no data passes through our servers

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Note version history: before overwriting a note, PL Markdown keeps a copy, also when the note changes in another app or through the agent or the AI. In the Version History window you pick a file and a version, see it as it was, see what changed compared with the current text or the previous version, step through the changes with the arrows, and restore it or save it elsewhere. Versions identical to the current text are marked. In Settings you choose how often to save and how many days to keep versions.
• "Move or Copy…": moves notes and files to another folder, project or vault together with their attachments, and updates the links. It also opens when you drag a file onto another vault.
• "Save to Vault…" brings a note opened from the Finder, or a new document, into a vault; "Open as Single Note", in the context menu, opens a vault note in a window of its own.
• Pinned tabs: the pin keeps a tab in place, and the files you open next open beside it instead of replacing it. Pinned tabs stay in front and come back pinned when you reopen the vault.
• "Attach file" also inside a property value, and a new attachment location, "Nearest attachments folder".
• Word documents preview with the same pages as in Word and real page numbers; Excel sheets preview with the file's colours, fonts, alignment, borders and sizes.
• Updated Mermaid diagrams, also in dark mode, with node tooltips in Live and in exported files.
• "Duplicate as…" shows the operation in progress and tells you if it fails; the file appears only when it's ready.
• History, Find in Files and Timeline have their commands in the toolbar.
• Fixes: bold no longer disappears while you type in Live; tables and their links in Live; moving several files at once updates every link; with a vault inside another, notes open in the right vault; formulas in exported Word, PDF and HTML documents; exported HTML stays light in any viewer; links in the preview of an HTML file open a new tab; windows have their own name in the Dock; missing translations; a crash when scroll bars are set to Always.
