We're building Nuclino (https://www.nuclino.com/ https://www.nuclino.com/), which is inspired by Notational Velocity / nvALT. You can upload images via drag and drop and embed code blocks. Syntax highlighting for the code blocks is on the roadmap. You can either share individual pages with a client (via a public URL) or invite someone to share several pages and collaborate on them in real-time.
