About this tool

CX Assist is an AI email reply and inbox assistant for Gmail and Outlook. Its main purpose is to automatically draft and send personalized email replies and organize the inbox, thereby helping users save time spent handling email each week.

Main capabilities:

  • Automatic email classification and organization: AI automatically labels each email, including Priority, Support, FYI, and Spam, and provides labels, filters, and a unified interface for viewing emails awaiting reply, isolating spam and noise.
  • Tone-based reply drafting: Drafts replies to each email in the user's tone, which the user can send with one click or edit before sending.
  • Rewriting and paraphrasing: Any text can be rewritten into a formal, friendly, shorter, or specific-persona-based version.
  • Automatic translation: Supports translation of emails and snippets in more than 100 languages.
  • Data and insights: Provides KPIs, sentiment trends, ROI tracking, and actionable insights.
  • Status tracking: View the processing status of each email in real time (Pending → Drafted → Sent), draft management, and usage counts (including plan limits).
  • Multi-platform layout: Provides mobile and desktop interfaces.

How to use:

  1. Connect a Gmail or Outlook account with one click; setup takes less than 30 seconds and requires no technical skills.
  2. Add a personal tone and writing rules; the Pro version can configure Slack, HubSpot, Stripe, and Shopify integrations.
  3. Drafts appear in the inbox, and the user reviews, edits as needed, and sends them; the Pro version can use tag-based auto-send.
