Write and connect ideas faster than ever.
When you link to a new page, a return link is shown on that page so you can get back to the first page. Bi-directional linking builds twice as many connections between your ideas.
When you link to a page that has links of its own, we show those secondary links in the first page's footer. This provides context for your ideas plus it helps you discover connections.
Use simple markup to add text styling and links while you type. Copy and paste media to embed inline. Everything is saved and styled as you go so it's fast to learn and even faster for pros.
