ChatVault docs
Installation
Put ChatVault within reach and prepare WhatsApp Web before your first export.
Install in the browser profile you use
Install ChatVault from its official extension listing and review the permissions presented by your browser. Use the same desktop browser profile in which you open WhatsApp Web; installing an extension in another profile does not make it available in your current session.
These instructions use Chrome menu names. Keep your browser and extension updated, and check that ChatVault is enabled in the browser extension manager before opening the exporter.
- Complete installation from the official ChatVault listing.
- Open the browser Extensions menu and locate ChatVault.
- Pin the extension so its icon stays on the toolbar.
- Open WhatsApp Web in that same browser profile.
Prepare the WhatsApp Web tab
Open web.whatsapp.com and complete the usual WhatsApp sign-in. Wait until your chat list and the conversation you want to save are visible. ChatVault reads the browser session; it does not sign in to WhatsApp for you.
Open the intended conversation and check an older message and an attachment you expect to include. What you can access in the web session matters more than what is visible only on your phone.
Open the popup on the correct tab
Keep WhatsApp Web as the active tab, then select the ChatVault toolbar icon. The popup offers Contacts / chats, date controls and export-format choices. Open it on the actual WhatsApp Web tab, rather than the extension store, browser settings or the ChatVault website.
After installing or updating ChatVault, refresh an already open WhatsApp Web tab. This lets the current extension code attach to the page before you start an export.
If the extension cannot read the page
Check the extension manager for site-access restrictions on web.whatsapp.com. In a managed browser, an administrator may control installation or access. If WhatsApp Web is still asking you to sign in, finish that step before trying ChatVault again.
If the popup cannot connect after an update, close it, refresh WhatsApp Web and reopen it. Continue with a small first export once the chat list loads correctly.
