User guide

Install the extension, translate messages, draft replies and use your writing style and product references. Learn how the AI trial works.

Install the extension

  1. Download and unzip the installation package. From the browser’s top-right menu, open Extensions and then Manage extensions. Turn on Developer mode, click Load unpacked and select the entire extracted folder. Do not move or delete that folder after installation.
  2. Open WhatsApp Web and sign in. Refresh the page after installing or updating the extension.

Account and AI Access

  1. Free basic translation requires no account. For AI features, register and verify your email or sign in from the extension Account page. Select AI translation when you have uses available.
  2. Click the translation button beside a message. In AI Mode, select AI Reply to generate a draft. Drafts are editable and must be sent manually.

AI Usage and Features

Free basic translation does not count toward your AI usage. Valid trial or purchased uses provide AI translation, replies, Q&A, writing styles and reference retrieval. The one-time professional unlock supports your own API key and models; your chosen provider bills usage.

Choose and Switch Translation Modes

Select Free basic translation or AI translation above the input area or in extension settings. AI Reply and Q&A require AI Mode. Switching modes never sends a message automatically.
