Think in branches, not in your head.
Linear chat can't hold a branching conversation — so you do, in parallel tabs, scratchpads, and copy-paste. Toggle AI represents every branch as a real tree, so the cost of holding it all is offloaded to structure.
Your working memory has a budget.
Deep, branching conversations eat the hold function of working memory — the effort of keeping every open thread in mind — and that starves your capacity to actually process. Put the holding into a tree and persistent Pins, and the thinking comes back.
Branch without losing the thread
Fork any point of a conversation into a child sub-thread. The original stays intact and immutable — branching adds structure, it never rewrites what you already said.
Carry exactly the context you mean
Highlight a passage to quote it into your next message — ephemeral, consumed on send — or pin it to keep it as persistent context you can return to.
Pin once, see it everywhere
A pin lives on every surface at once — the Pin panel, the map, the outline count. Unpin anywhere and it's gone everywhere. One source of truth, always in sync.
See the whole shape
The Map panel renders your conversation as a tree of structure and pins — not a wall of text — so you always know where you are and what's still open.
Three panels, split as you like
Map, Conversation, and Pins are fixed regions; inside Conversation, split into Obsidian-style panes and keep several threads open side by side.
Clean, isolated workspaces
Each workspace owns its own tree and context. Jump between workspaces without leaking pins or history across boundaries.
Three decisions, cleanly separated
Toggle splits what most tools fuse together — so placement never becomes a mode you have to set in advance.
Highlight — what context
Select the part of a turn worth carrying. Quote it for this message, or pin it for good.
Type — what to say
Write your message in the input area. Nothing is committed until you send.
Place — where it goes
Enter continues the thread. A modifier sends it as a branch or a sibling instead — decided at send, not locked in beforehand.
