Chat&Messenger is an all-in-one groupware platform from Chat&Messenger Inc. that consolidates business chat, web conferencing, scheduling, document management, workflow approvals, and attendance tracking in a single interface. The platform is adopted by enterprises, banks, government agencies, universities, and hospitals that handle sensitive information.

The platform supports flexible deployment models including cloud, on-premises, and hybrid configurations that let organizations mix deployment types by team to match different security policies. The IP Messenger compatibility mode lets existing IPMsg users switch between legacy and modern chat modes during migration, reducing adoption friction for organizations with established communication patterns.

The free plan includes core business chat, web meetings, shared calendars, task management, file sharing, and mobile access without restricting team size. Paid tiers add advanced administrative features, enhanced security controls, and enterprise support options.

An English version of the website is available, and the platform mentions support for multiple languages, though mobile apps are currently available only in Japanese.
