Getting started with the browser extension

The extension exports chats straight from WhatsApp Web in your browser. Messages are read from the page you already have open and converted locally.

1. Install from the Chrome Web Store (link on the Download page), open web.whatsapp.com and sign in to ThreadVault from the extension popup.
2. A ThreadVault panel appears inside WhatsApp Web. Open a chat, choose the range and format, and export. Long chats are scrolled and collected step by step — keep the tab open.
3. The file downloads through the browser. Media downloads are optional and plan-dependent.

Good to know

• The popup shows your plan, remaining chats for this period and the device slot the extension uses.
• "Stay signed in" keeps the token on this profile; turn it off on shared computers.
• Chrome may pause background work when the tab is hidden; keep WhatsApp Web in the foreground during large exports.
• If WhatsApp Web changes its layout and the panel disappears, update the extension — a fix usually ships within days.
