Real-Time Collaboration

HVAKR projects are multiplayer. Several people can open the same project at once, and every change syncs to everyone in real time.

How It Works

Live Sync

HVAKR saves and syncs as you work:

• Edits appear for other collaborators within moments: there’s no manual save or refresh
• Changes are written field by field, so teammates editing different things don’t overwrite each other
• If two people change the same field at the same time, the most recent edit wins

The save status icon next to the project name shows Saving while your edits are being written and Saved once they are stored. Hover it to see which.

Use Undo / Redo in the toolbar to step back through your own changes. The buttons appear once you have made a change.

Presence

The top toolbar shows an avatar for each collaborator:

• People currently in the project show a green dot; everyone else is dimmed and sorted after them
• Hover an avatar to see the person’s name; when there are many collaborators, the extras collapse into a +N badge
• Click the avatars to open the Share panel

Live Cursors

You can watch teammates’ cursors move around the project. This is off by default, and each person turns it on for themselves:

1. Open the account menu (your avatar, top-right of the toolbar)
2. Click Realtime Cursors to toggle it on: the eye icon next to it shows whether it is on

The setting applies only to the current project in this browser. Turn it on again for each project and device.

Both people must turn it on. HVAKR shares your cursor only while your toggle is on. It also shows you other cursors only while your toggle is on.

Each collaborator who has it on appears as a colored cursor with their name. You see only the cursors of people on the same page as you.

A cursor that has not moved for 30 seconds disappears. It comes back when that person moves it again.

Chat & Comments

The Chat button in the toolbar (shown on every licensed plan: Solo, Team, University, and Enterprise) opens a shared conversation for the project. A badge shows how many messages you haven’t read yet.

• Message your team: type in the composer and send; messages are grouped by day, and the search button in the Chat header finds past messages, including replies
• @mention: type @ or click the person button under the composer to mention a teammate and loop them in; mentioning someone who isn’t on the project yet prompts you to invite them
• Attach files: click the paperclip button, drop files onto the window, or paste a screenshot into the composer. Chat accepts images, PDFs, Excel, Word, CSV, and text files. Each file can be up to 25 MB. Images show as previews. Other files show as cards with the file name and size. Click an attachment to open it in a new tab
• Comment on an element: open the context menu for a space, zone, or system (right-click it on the canvas) and choose Add Comment to open Chat with that item attached; the composer notes which item you’re commenting on
• Reply in threads: reply under a message to keep a discussion together; replies can carry attachments too

Best Practices

Divide the Work

To stay out of each other’s way:

1. Split work by area: different floors, zones, or systems
2. Use Chat to say what you’re working on
3. Attach comments to the specific space, zone, or system in question

If Your Connection Drops

If your browser goes offline, HVAKR shows a Connection Lost dialog and pauses editing. It doesn’t store offline edits, so there’s nothing to sync on reconnect. The dialog has a Refresh button if you want to reload the page manually. When your connection returns, the dialog closes automatically and a Connection restored. toast confirms it.
