W10X is a free Chrome extension designed to enhance user experience on WhatsApp Web by providing comprehensive CRM functionalities. This tool allows users to organize their chats efficiently and optimize business operations through features like mass messaging, contact export via CSV, and customizable tabs for important contacts. It also supports a Kanban view for lead organization and the ability to send messages to unsaved numbers, making it a versatile solution for managing customer relationships.

Additional features include personalized notes for each contact, reminders for follow-up calls, and integration with Google Calendar for scheduling meetings. W10X also offers quick response templates, contact export from groups, and multilingual support. Security is a priority, as the extension has passed a Google Chrome security audit and operates without a database, ensuring that all data is handled locally on the user's computer.
