Share privately. Comment. Edit together.

Share a note with a person, not the public web.

Share a document directly with someone by their email and it lands in their Shared with you section the next time they open 1Presence — no link to leak, nothing public. They need their own account to see it, and we never reveal whether an email is signed up, so sharing gives nothing away.

Choose what each person can do, and change it any time:

• Read. They see the document, typeset for reading. Nothing more.
• Comment. They can leave notes and questions in a side panel beside the document — a conversation about the work, kept separate from the work itself.
• Edit. The document opens for them exactly like one of their own — same page, same editor. There is only ever one copy, so you both always see the latest.

Every change is captured against the document — who made it and when — and you can both look back through the whole history and restore an earlier version. If two people reach for it at once, nobody's work gets quietly overwritten: the second save is held back with a nudge to refresh first.

When a document someone shared with you is open, Presence can help with it too — read it, summarise it, or, if you have editing rights, make changes — just like any of your own notes. Its edits are captured in the same shared history, so the other person sees exactly what changed and when.

Your notes link to each other, and those links keep working when you share. If a document you have shared points to another you have also shared with the same person, the link is live — they can click straight through. Links to anything you have not shared simply stay as plain text, so following a link never opens a door to the rest of your vault. Share a set of connected notes and they read like a small, self-contained site; share one and it stands alone.

Change anyone's access, or stop sharing entirely, whenever you like. For sending something to the world rather than a named person, a one-tap public link is there too — typeset for reading, with a social preview, revocable any time.
