"Obsidian can be used 100% with zero cost."

"The free version does not support real-time collaboration."

May 29, 2025

Jake P.Account ExecutiveHospital & Health Care, 1001-5000 employees

"The file sharing mechanism is very smooth—we can drop images and documents straight into a chat, and the search functionality is powerful enough to find old files or specific conversations from months ago using simple keywords."

Arthi R.EngineerAccounting, 1001-5000 employees

"Its free plan has limited message history and integrations. While it’s great for real-time chat, Slack isn’t ideal for long-form discussions or detailed project management."
