Features

Everything OV can do, in one place. Each section ends with a Try it in your browser button.

In a hurry?

Read just the five core sections. Stays on your computer, An editor that feels right, Tables · boards · calendars, Calendar & schedule, and AI assistant — those five are what make OV, OV.

Stays on your computer

Every note is a plain file on your disk. OV works fully offline, and your data is never locked into someone else's service.

Properties — tags, dates, favorites, anything you like
Switch between folders — keep work, hobbies, and archives separate
Crash-safe writes — a power outage mid-save won't corrupt your file
Live reload — edit a file from another app and OV refreshes instantly
Drag-drop reorder — move notes between folders right in the sidebar

Default vault location: ~/Documents/OV/ (macOS · Linux), C:\Users\<user>\Documents\OV\ (Windows).

Create a note in the editor

An editor that feels right

A writing experience without friction. The output is a plain file that opens in any other tool.

IME-safe composition

We took extra care with Korean / Japanese / Chinese composition. You won't see a cursor jump or characters disappearing while you're composing.

Use the slash menu yourself

Tables · boards · calendars

The same notes, three perspectives. What you write becomes columns automatically.

Table view — `⌘2`

Click a header to sort, type to filter
Edit cells inline (text, select, date, checkbox, number)
Add, rename, hide, or delete columns

Board view

Group cards into columns by a status or category property
Drag a card between columns — the property value updates automatically

Calendar view

Notes with a date show up on a calendar automatically
Toggle Month / Day views

Toggle through table · board · calendar

Calendar & schedule

You don't need a separate calendar app.

Month view — month grid; click a date to expand its schedule
Day view — time slots (6 AM – 11 PM) with a NOW line that tracks the current time live
Click empty time → add a new event
Events ↔ tasks — events on the calendar also show up as task checkboxes

Events are saved as ordinary notes. You can freely edit start time, end time, and description.

AI assistant

It understands your notes — but never changes a single character without your approval. Every edit passes a user-approval gate.

Invoke: ⌘J — from anywhere
15 actions: read notes, search, create events, refine notes, create new notes, rename, and more
Time-aware — natural language like "today", "tomorrow", "next Monday"
Pick the model — a default model, swap it in settings

What gets sent

Item	Sent to the AI service?
System prompt	Yes
Vault summary (file names, folder structure)	Yes — not contents
Active note metadata	Yes — name, size only
Active note contents	No — only fragments the AI explicitly reads
Chat history	Yes (conversation context)

Where the API key lives

It's encrypted in the OS keychain. The key never touches disk in plaintext.

Bring your own key (BYOK)

OV does not run its own AI service. Calls go directly to the provider using your key, so you can see your real usage and billing exactly as the provider charges them.

Run the 6 Copilot scenarios

Spotlight — your vault notes show up in macOS search
Apple Calendar · Reminders — sync events with the system Calendar and Reminders
Native notifications — upcoming events arrive as OS notifications with Snooze / Done / Open actions

Security & privacy

See the privacy page for the full breakdown. In short:

App password — prompted on every launch (optional)
Per-note locking — AES-256 encryption (PBKDF2-SHA256, 200k iterations)
Safe file handling — multiple layers of validation block unintended path access
CSP — unknown external scripts and network calls are refused
All file writes — atomic and path-validated before they hit disk
