What is the WhatSender Chrome extension free trial?
The free trial gives you 24 hours of real WhatsApp Web translation — incoming bubble cards, smart compose, Listen text-to-speech, and Translate Chat for older messages. You verify your email on the extension page, receive a trial license key, and activate it in the Chrome extension License tab.
No credit card. No payment. No Google Translate API key. One trial per email address and browser fingerprint. When you buy the full license, the same key upgrades — no reinstall required.
No Google Translate, OpenAI, or Whisper API keys required. Buy one Chrome extension license (or start the free 24-hour trial) and use every included feature until expiry — translation, recording, transcripts, export, and analytics run inside your browser.
