## What is Orviss?

Orviss brings your calendar, Markdown notes, files and a daily journal together, organized by project and by day. Everything is a plain file in one folder, so nothing is locked in.

NEW IN 2.0: SYNC AND SHARING
• Orviss Pro syncs your Orviss folder between your Mac, iPhone, iPad and Windows PC.
• Share a project and give each person a role: co-owner, editor or viewer.
• People you share with need a free Orviss account, but not Orviss Pro.
• Shared projects arrive in everyone’s Projects folder as ordinary files.
• Edits on different lines are merged. If they clash, both versions are kept.
• Work offline. Changes sync when you’re back online.

WORK BY PROJECT
• A project is a folder for anything: code, notes, specs, web pages and mail.
• Every project starts with a Project Overview note.
• Next Up gathers the unfinished items from a project’s notes.

WORK BY DAY
• See and edit the day’s events beside your notes.
• Every day gets a folder with a Journal note, for daily reports or a diary.
• The day’s home shows the photos you took and the files you touched.
• Read a week or a month of journals on one page.

MARKDOWN AND MERMAID
• Every note is a .md file any app can open.
• Live, split and preview modes, with checklists, tables and images.
• Draw flowcharts, sequence diagrams and Gantt charts with Mermaid.
• Export notes as PDF.

AND MORE
• Plain folders and Markdown let other apps, scripts and AI agents read your notes too.
• On supported devices, Apple Intelligence summarizes a period and drafts documents from your notes, on the device.
• Stickies, search, widgets, Shortcuts actions and the share sheet.
• Keep the Orviss folder in Documents, iCloud Drive or any folder you like.
• Markdown templates and 30 themes.

FREE, WITH ORVISS PRO FOR SYNC AND SHARING

• Sync: Orviss Pro syncs your whole Orviss folder between your Mac, iPhone, iPad and Windows PC. On every device, each note is still a plain file.
• Share projects: invite people to a project and give each a role: co-owner, editor or viewer. They need a free Orviss account, but not Orviss Pro.
• Invitations to you appear in Settings, with a badge on the Projects tab.
• Plans for 2 to 100 people, paid monthly or yearly. Start in Settings → Orviss Account.
• New in Help: “Syncing and Sharing”. The welcome tour has a new page about Orviss Pro.

Everything that worked without an account is still free, and your notes stay in your Orviss folder.
