Basics of Space Features

Space is a feature used to communicate with each team. You can create a space for a set of attendees you chose, and discuss topics and share information within. Space

Splitting Threads by Topic

When a space has multiple topics of communication, you can create threads in the space. Thread is a collection of comments related to a certain topic. You can organize topics of communication in the space by splitting threads by topics so that users can post comments to topic-related threads. Threads

For details on how to add threads into spaces, see the following page:
Adding Threads

Managing Data by In-Space Apps

Apps can also be used to share information within a space. You can add apps into a space, and manage information required to communicate in the space, documents, and To-Dos.
An app that is added into the space is referred to as "in-space app". For details on in-space apps, see the following page:
What Is an In-Space App?

Sharing Information with External Users Using Guest Space

Guest Space is a space where external non-kintone users can join as guests.
You can invite external users (customers, business contacts, partners, etc.) as guests.
Guest users can view/post threads or use in-space apps, only within the invited quest space.
By separating the space from the internal environment, you can avoid information leakage and share information securely.
