Octo

We are committed to offering an excellent writing experience on all of your devices. A great writing app gets out of your way and makes it simple to get your thoughts down as easily as possible. Markdown is a great language for writing content, especially when there is code involved, but we have to render it to see what our final document looks like. Depending on the approach used, this can be a huge interruption to your writing flow. We take a unique approach in Octo with a hybrid markdown editor called Ink (which is also open source). Instead of replacing the plain-text markdown of your document, we just apply some light styles to it directly.

We take your privacy and security seriously. While we offer user accounts for additional functionality - such as document syncing, document sharing, and backing up your data - they are not required to use Octo. Unless you decide otherwise, your data never leaves the browser. Designed to be offline-first, everything Octo needs to function is now on your machine just by loading this page. If you decide to sign up for an account, you can always take advantage of client-side encryption to ensure no one sees your data but you. We use best practices, as many apps do, but end-to-end encryption is the recommended way to be sure that your data stays private for good. Your data belongs to you, not us. We can't hold it hostage, and you can export it any time.

Your brain stores information in a network of interconnected neurons. Shouldn't your information tool do the same? In Octo, we use tags to link documents together in the format of #some_tag. You can add them anywhere (outside of code). Beyond tagging your docs, we also give you the power of regular expressions to search your documents any way you see fit. Regular expressions are incredibly powerful and flexible. We don't assume we know how you want to search your data, so we prefer to give you the tools you need!
