Freemind is a Mind mapping tool which is free of cost. Most of my project and  plannings are managed by this tool. Try it if you have not started using mind mapping tools. It is easy to go through a presentations or meetings. Currently my file has lot of  personal details which are not sharable. This lead me to think about a password protected mind map file. Finally i noticed that there is an option to encrypt files in freemind. The main advantage is that we can create nodes without password in the same file.
