- If you are looking for something lightweight, Nuclino would be a great option. It's fast and minimalist and allows you to structure your documentation in a much more organized way, using a kanban board or a mind map for example. It's also free.
- Authorea is specifically useful for professional documents - scholarly papers, essays, technical reports, documentation, legal and financial reports. Documents you create are version-controlled (Git under the hood), and data-driven. Enterprise (on-premise) version available.
