Install Lexpad in Brave,
Opera or Vivaldi

Brave, Opera and Vivaldi are built on Chromium, so they install extensions from the Chrome Web Store. There each shows its own button: Add to Brave, Add to Opera or Add to Vivaldi. Here are the steps for each, taken from the browser’s own help.

Available in the Chrome Web Store

The extension is free and works with a free Lexpad account. After you add it, click Connect to Lexpad and sign in, or create your account. You never type a password into the extension.

The three side by side

Where each browser puts things. The names are the ones each browser’s help uses.

If something does not work

  • Brave: the sign-in window stays blank. Brave Shields block trackers, and can block scripts, site by site. Open app.lexpad.app in a tab, click the Shields icon in the address bar and set Shields down for that site, then choose Connect to Lexpad again (Brave Help: Shields).
  • Opera: no Add to Opera button. Update Opera first. Opera’s FAQ says to click Add to Opera; an older Opera help page says to add Opera’s “Install Chrome Extensions” add-on before that, so if your Opera still asks for it, add it from Opera’s add-ons store and try again (Opera Help: Customization).
  • Vivaldi: no Add to Vivaldi button. Open Settings, Privacy and Security, Google Extensions, and turn on Web Store (Vivaldi Help).
  • Vivaldi: Lexpad’s button is gone. It may be hidden. Use the Show/Hide hidden extensions toggle at the right of the Address Bar, then right-click Lexpad and choose Show Button. Settings, Address Bar, Extension Visibility can list hidden extensions in a drop-down instead.
  • Brave: Lexpad’s button is gone. Open the puzzle-piece menu next to your extensions and pin Lexpad again.
  • Nothing happens on a page that was already open. Reload the page. Lexpad starts on pages opened after it was added.
  • Still stuck? Write to us, with the browser’s name and version.

Good to know

Questions

Where do Brave, Opera and Vivaldi get Lexpad?

From the Chrome Web Store, the same listing Chrome uses, so you get the same version (0.5.0) and the same updates. Each browser shows its own name on the button.

Do I need a separate account for each browser?

No. Install Lexpad in each browser and connect it once with the same Lexpad account. Every browser saves to the same notebook, which you also see on the web, in the Android app and in Lexpad for Mac and Windows.

Is it free?

Yes. The extension is free on every plan and works with a free Lexpad account. Each meaning it writes uses the same AI allowance as the app: 25 AI cards a day (400 a month) on Free, 150 AI cards a day (2,000 a month) on Pro. Every new account gets Pro free for 14 days, no card needed.

What does Lexpad ask permission for?

Storage, the right-click menu, the browser’s sign-in window (to connect) and access to the Lexpad API; never your tabs, your history or permission to run remote code. Read the privacy policy.

How do I remove it?

Open the browser’s Extensions page (the steps for each browser are above) and choose Remove. Your words stay in your Lexpad account.

Can I use it on my phone?

The extension is for a computer. On a phone, add words in the Android app or the web app; they land in the same notebook.
