HackMD

I used HackMd for months in my work, my email account associated with the service went through a migration process but the same email was kept, all other services were migrated correctly and I had no problems, except HackMd which for some reason created a new ID and overwritten my old account with a new account. The result is that I lost all my important documents. I contacted support and got no response. I have currently migrated to another service, do not trust the security of their cloud service

Simple and smooth user interface, great performance when it comes to collaboration(yeah speed is everything), rich markdown extended syntaxes, and with GitHub integration. HackMD is by far the most satisfying markdown editor for me!

HackMD is a great tool for taking structured notes during meetings, creating a brief project outline, or collaborating on a full project brief. The developers are highly responsive, and I couldn't recommend this product more!
