Work on the same conversation as someone else
“Explaining what the AI just did is slower than showing them.”
Share a running session and both drive, or export a finished one as a file they can continue in their own copy.
Send a finished session as a file
An encrypted .plexshare. They drag it in, or open a plexon:// link, and can carry on from where you stopped. No cloud and no accounts.
Try this
Export this session as a .plexshare file I can send. Tell me what goes into it before you write it, and leave out anything from a locked chat.

Or share the one you are in
You send an invite code, they send one back, and the two apps connect directly. Not even the connection details reach a Plexon server, and you both check four safety words first.
They start read-only
Guests wait to be admitted and watch until you promote them. Turn-taking stops two prompts colliding, and tool output that could expose your machine stays hidden from them.
Mark the part that mattered
Pin it and it is findable later from any project on the machine.
What you end up with
Two people in one session, or a portable file that opens with everything intact. Neither goes through a Plexon server.

Ship a feature without babysitting every edit
Plan first, fan the work out across isolated worktrees, review every diff in one place, and let the pull request wait for your approval rather than your attention.
Move your existing setup over in one pass
Agents, MCP servers, hooks, plans, memory and every conversation come across, labelled so you can tell what was imported.
