Team Chat

Japanese team chat services give a company a closed space for work messaging, in place of email threads or employees’ personal messaging apps. Usually only people an administrator registers or invites can join, and the administrator removes them when they leave.

Most pair group and direct chats with file sharing, search, voice or video calls and task management. Many show who has read each message, so a manager can confirm an instruction reached everyone. Administrators can restrict sign-in by IP address or device, and guest accounts admit outside partners to chosen chats. In some services, an administrator or designated auditor can also search or export message logs for audits. Several target deskless staff on smartphones at construction sites, shops or care facilities.

Within workplace communication tools, this category covers products built around real-time messaging. Some stay close to plain chat, while others add calendars, bulletin boards, project management or employee recognition.

Generative AI in the chat summarizes threads, drafts messages, answers questions from company documents or writes meeting minutes.

An API or webhooks let other systems post notifications into chats and let developers build bots, such as one that collects daily reports.

A free plan with no end date, limited by user count, message history or storage.

Staff chat from the business app with customers, job applicants or part-time workers who use the consumer LINE app and install nothing new.

The organization runs the chat server itself, even on a network cut off from the internet, which suits government bodies and hospitals that cannot use cloud services.

Messages or posts are translated automatically or with one tap, so staff who speak different languages can share a chat.

Users sign in through the company’s identity provider, usually over SAML, or with Windows integrated authentication on some on-premise installations.

Approval workflows: an employee files an expense claim, leave request or similar form, and it passes through a set route of approvers.
