Voice is fast, but it forgets. Chat is slow, but it lives in another window. Slate is the missing middle — a shared document that takes shape while you talk, that you can point at, edit out loud, save, or throw away. The whiteboard for the AI era.
Press ⌘⇧S to open the slate. Say what you're thinking. The conversation rail captures the dialog — your turns collapsed, Iris's replies in italics, tool calls as chips.
The artifact pane is the document. Each turn either writes a fresh draft or surgically patches one block — "the second bullet under Risks" — without disturbing the rest.
"Tighten that section." "Drop the third bullet." "Add a paragraph on rollback." Slate listens, Iris patches. The doc gets sharper turn by turn.
Save as markdown when it matters. Snapshot history catches every prior version. Walk away when it doesn't — the slate was always meant to be a whiteboard.
Voice-only chat has a memory hole — the assistant says something useful, you nod, ten seconds later it's gone. You can't point at "that second bullet" because there is no second bullet. Slate gives the conversation something to rest on.
Iris speaks substantively about anything she puts in the slate — never silently emits artifact-only. The doc and the dialog stay in sync. Talk is the input; the doc is the output; you don't switch modes to write or edit.
Each block has a stable, human-readable ID — risks/p2,
wins/list1. When you say "the risks section," Iris
knows what that means. Patches splice in place; the rest of the doc
holds still.
A slate is a whiteboard, not a permanent record. Snapshot history keeps the last eight versions for safety. Save when something earns it. Otherwise — close the window and it's gone, like any real conversation.
Voice in, Iris drafts, artifact updates live. ⌘⇧S to open.
Named blocks, in-place edits, snapshot history with undo.
KaTeX, Mermaid diagrams, syntax-highlighted code (Tree-sitter — Python, JavaScript, Swift, more).
Type directly into the doc; voice and text co-author the same surface.
Tabs, find across slates, live file references that open inline.
Select a block, hold the hotkey, say "make this tighter." It happens.
Slate is live in the latest Super Voice Mode build for Pro subscribers. Free trial, no credit card required.
