About Obsidian is a powerful knowledge base that works on top of a local folder of plain text Markdown files. The human brain is non-linear: we jump from idea to idea, all the time. Your second brain should work the same. In Obsidian, making and following "connections" is frictionless. Tend to your notes like a gardener; at the end of the day, sit back and marvel at your own knowledge graph. Note-taking is incredibly personal. Tried every app, but there's always something not quite right? You deserve better. Obsidian is built to be extensible. With 22 core plugins and 149 community plugins, set up your own toolkit and get running in minutes. You'll even be able to install third party plugins or build your own once Obsidian reaches v1.0. Sky's the limit. In our age when cloud services can shut down, get bought, or change privacy policy any day, the last thing you want is proprietary formats and data lock-in. With Obsidian, your data sits in a local folder.	About Cut down email volume by up to 95% and get one source of truth for all conversations, data, and documentation through shared team inboxes. Unlike siloed email accounts, SEDNA gives team members controlled transparency of all correspondence, attachments, and actions taken within a project or message thread—along with quick composition and sharing capabilities—for more efficient communication and effortless collaboration. Each email within a team inbox has its own activity panel to host internal conversations, contextual data, and time-stamped activity that enables team members to work with—and around—one message in place of forwards, reply-alls, and cc’s that bloat email volume. The Activity Panel lets you see automatically generated or manually applied message details like category tags, job references, and people involved, as well as who viewed the message, who replied, and how so. And collaboration is easy with the ability to tag others and add comments for real-time discussion.
