What this means in plain English: Like Microsoft Word or Excel — you download it once
and it lives on your computer. It is included at no extra cost in every Vertinab plan (Starter, Professional, and Business).
If you turn on Local AI, your conversations never leave your device — no data goes to the cloud,
and there are no monthly message limits.
HOW TO INSTALL ON A MAC
1
Click the macOS download button below
Choose Apple Silicon if your Mac is an M1, M2, M3, or M4 (bought 2020 or later). Choose Intel if it is an older Mac. The file downloads to your Downloads folder.
2
Open the downloaded .dmg file
Double-click the .dmg file. A window opens showing the Vertinab icon. Drag it into your Applications folder.
3
Bypass macOS security (one-time step)
macOS will block the app the first time with a message saying "Vertinab Not Opened". This is normal for apps not yet on the Mac App Store. Follow the fix below.
⚠️ macOS Security — "Vertinab Not Opened" message
macOS Gatekeeper blocks the app because it is not yet Apple-notarised. To open it, follow
one of these two methods:
Method A — System Settings (easiest):
1. Click
Done on the warning dialog.
2. Open
System Settings → Privacy & Security.
3. Scroll down until you see
"Vertinab was blocked".
4. Click
Open Anyway and enter your Mac password.
Method B — Terminal command:
Open the Terminal app and paste this command, then press Enter:
xattr -dr com.apple.quarantine /Applications/Vertinab.app
Then double-click Vertinab to open normally. You only need to do this once.
4
Sign in with your Vertinab account
Use the same email and password as the cloud version. If you do not have an account yet, click "Sign up free" on the login screen or visit the website first.
5
(Optional) Switch to Local AI for offline and unlimited use
Download Ollama from ollama.com/download — it is free. Then in the Vertinab desktop app, click the green/blue dot in the bottom-left sidebar → click the ⚙ settings icon → choose "Local AI" → click "Install a model" → select Llama 3.2 (Fast, 2 GB) → click Download. Once installed, your AI runs entirely on your computer with no message limits.
HOW TO INSTALL ON WINDOWS
1
Click the Windows download button below
A file called Vertinab_0.3.0_x64-setup.exe will download to your Downloads folder.
2
Run the installer
Double-click the .exe file. If Windows asks "Do you want to allow this app to make changes?" click Yes. The installer runs and Vertinab appears on your desktop and Start menu.
3
Open Vertinab and sign in
Double-click the Vertinab icon on your desktop and sign in with your account.
4
(Optional) Switch to Local AI
Same as Mac — download Ollama from ollama.com/download, then install a model inside the Vertinab app settings for offline, unlimited use.
