A notebook for the curious

Every idea you save,
kept in orbit.

Capture pages, videos and posts in one click. Write in a fast block editor, share a workspace with the people you think with, and lay it all out on a canvas where your ideas can finally meet.

Socionaut's notes view: a sidebar with folders and tags, and a list of saved notes from YouTube, X, GitHub and the web, each with its folder and tags.

Captures from

Capture

Save in a click. Come back to the exact second.

Whole pages

Articles, docs and repos land as a note with the title, a link back to the source and its description, filed straight into a folder.

Videos, to the second

Save a YouTube video mid-watch and the note keeps the channel, the length and a link that reopens it right where you paused.

Highlights and posts

Select a passage and save just that. It becomes a quote in your note, ready for your own thoughts underneath. Posts from X, Instagram and TikTok work too.

What lands in your notesA captured talk keeps its channel, its length and a timestamp that jumps back to 14:32. Your own notes sit right underneath.
