Best Document Collaboration Software in 2026

Working together on documents can mean inviting outside contributors, controlling access, and keeping track of revisions. Compared on approval workflows, audit logs, collaborator limits, guest access, role permissions, and version history, these options give you several ways to assess how a team might manage shared work. AFFiNE, Nuclino, and Lark are among the named tools to consider. Check whether a free plan is available and where paid pricing starts, then weigh those details against the access and review steps your documents require. The comparison can help you focus on who needs to contribute, how tightly permissions should be set, and whether revisiting earlier versions or recording changes matters to your process.
