A writers' room on demand.
Open a brainstorm, choose who answers, attach the chapters they should read, and talk it through.
What you can do
Free conversation
Start on a topic, choose who answers (any role, or no one for notes to self), attach pages for the agent to read in full. Nothing in the book changes.
Streaming replies
In-app agents reply word by word as they write; webhook agents reply when they're ready.
Agents that push back
In brainstorms, agents offer options with a recommendation, ask sharp questions and get concrete: names, beats, lines.
Pull in other agents
@mention any role mid-conversation and it joins.
Make it so
Pick who does it and, optionally, what exactly. The agent reads the whole conversation and submits one proposal (outline changes, drafted scenes, codex entries, timeline events, plotlines), leaving out the ideas you rejected.
Manage threads
Rename, change who answers, attach or detach pages, close, reopen, delete.
No length limit on what you write
Paste a whole chapter or a page of notes. Agent replies are capped only by the model's output limit.
Listen to any message
Play any message aloud with the free on-device voices.
Questions
Does a brainstorm change my book?
No. Brainstorms are conversation only. Changes happen when you press Make it so, and even then they arrive as a proposal you accept or reject.
Is brainstorms included on the Free plan?
Yes. Every feature is on every plan. Plans differ only in in-app agent allowance and workspace members.
