Two halves, both deliberately scoped: a read-only WhatsApp group & chat contact extractor, and a compliant campaign sender built on WhatsApp's own official API.
Open the extension on web.whatsapp.com, select one or more groups or individual chats, and click Extract. Senextrac reads names and phone numbers directly from data WhatsApp Web already has loaded — most groups extract instantly, with no need to open each one by hand first.
Select any number of groups at once and extract them in a single pass, instead of one at a time.
Extract names and numbers from your 1:1 WhatsApp chats, not just groups.
For WhatsApp Business accounts, scan your custom Lists and extract every chat inside one.
Extraction only ever reads what's already loaded or what WhatsApp's own internal data provides — it doesn't click through or search your chat list.
Export every selected group combined into one file, or as a separate file per group with each one automatically named after the group. CSV exports open correctly in Excel regardless of your system's regional settings.
Senextrac's sender does not automate WhatsApp Web. It sends through the official WhatsApp Business Platform (Meta's Cloud API) — the same infrastructure real WhatsApp Business integrations use — with approved message templates and real, published rate limits instead of simulated clicks.
Every recipient needs a recorded consent date and source before a campaign will queue them. Anyone who replies STOP is automatically suppressed from future sends.
Pro accounts can attach an image or document to a campaign, sent as the template's header — on Free, campaigns are text-only.
Works as a browser extension on both Chrome and Firefox, directly on web.whatsapp.com.
