If i want to make quick free-form notes about things, I use Notes.app (the Apple app). I don&#x27;t have to &quot;explicitly save&quot; it, it has hierarchy, and it has rich text if i want it.<p>If I&#x27;m writing more thought out, structured information (e.g. I&#x27;m using this method to define the deliverables&#x2F;goals&#x2F;basic use for my company&#x27;s software packages) I use a VCS repo with markdown files in it. This allows me to link between the documents, and when I get around to it, make it accessible via a simple wiki tool like Gollum. This is the opposite of your &#x27;no specific saving&#x27; thing though - you have to not just save it, but also commit and push.
