TabHero — New chat. Same tab.

Open WhatsApp conversation links in your existing WhatsApp Web tab, keeping the phone number and message.

Already open? TabHero knows the way. • Open supported conversation links inside the already loaded WhatsApp Web tab, preserving its document and session. • Choose a loaded chat using search, then send free text or a saved reply from the compact toolbar popup. • See a silent unread badge and the latest incoming text, or a media placeholder with an available caption. • Optionally connect your own OpenRouter key for an editable AI suggestion. AI never sends automatically. No developer server receiving your chats. No advertising, analytics or sale of your data. TabHero intercepts supported conversation links and accesses loaded WhatsApp chat names, unread counts and message previews to provide its features. Messages are sent through your WhatsApp session only when you click Send. Saved replies and your optional OpenRouter key stay in local extension storage in this browser profile, without browser sync. Drafts and send-operation records use browser-session storage. We do not build or upload a chat-history archive. AI is optional. Only after you connect your own OpenRouter key and click Suggest, the displayed received text (including any caption) and your draft go directly to OpenRouter and its AI provider. Your key authenticates that request. Their policies govern processing and retention. Media files are not sent to AI. Delete saved replies in My saved replies. Disconnect AI in settings to remove its saved key and permissions. Drafts and send-operation records expire with the browser session. The source is public under the MIT license. Inspect the code, build it yourself, report issues and compare the source with the release you installed. Free and ad-free. Optional GitHub Sponsors support does not unlock features or change functionality. Experimental desktop integration. Keep WhatsApp Web open and signed in, in the same browser. Internal WhatsApp interfaces may change. A successful send means WhatsApp accepted it, not that the recipient received it. AI availability and limits depend on OpenRouter. Independent project. Not affiliated with or endorsed by WhatsApp or Meta. Experimental integration; internal interfaces can change.
