Features
The whole instrument.
Everything here serves one relationship: you direct, StoryProp drafts, and the project holds together across months of work.
The workspace
Editor beside agent
Your manuscript on the left, one persistent partner on the right, both working on the same document. On a phone, full-width Editor and Agent views that switch without losing anything.
The conversation
One partner, no personas
The same partner carries brainstorming, research, planning, drafting and revision. It infers what kind of work you're doing; you never pick a mode.
Drafting
Small by default
An opening, a paragraph or two, then back to you. A full chapter or a whole named scope happens only when you explicitly ask for it.
Annotations
Point at the text
Select passages, attach notes, add one instruction that ties them together, send once. The agent handles the combined turn the way you meant it.
Research
Sources that file themselves
Name an unfamiliar work and it researches immediately, saving cited sources with provenance and dates. Research stays evidence; it never quietly becomes canon.
Project knowledge
Records, not vibes
Canon, characters, style and structure live as records you can edit directly or ask the agent to update. Both paths change the same record.
History
Every version, kept
Autosave, grouped sessions and agent passes, side-by-side comparison, non-destructive restore, and whole-pass undo in one action. Duplicate a document or a work to take an alternate direction without losing the first.
Formats
Five families, real conventions
Prose feels like a familiar word processor. Screenplays, television and stage work use semantic elements that drive professional layout automatically.
Export
Clean, professional, yours
Polished downloads across the approved formats, including FDX and Fountain for scripts. Any byline you choose, and nothing of ours added anywhere.
Reliability
The backend owns the work.
Closing the laptop doesn't cancel a run. Come back and the draft is finished, or rejoin the same run in progress. If inference truly fails, your manuscript returns to its exact pre-run state while the partial work stays recoverable.
Fair questions
How it actually behaves.
Is StoryProp one AI or a cast of specialists?
One partner. It infers whether you're brainstorming, researching, outlining, drafting or revising and behaves accordingly — you never pick a persona or switch a mode, and the voice across your whole project stays coherent.
What happens if I close my laptop mid-draft?
Nothing bad. Runs live on StoryProp's backend, so a closed lid, refresh or dropped connection doesn't cancel work. Come back and the draft is finished, or rejoin the same run in progress.
Can I undo what the agent wrote?
Always. A whole agent pass undoes as one action, history is grouped into understandable sessions and passes, and any earlier version can be compared and restored non-destructively.
How do annotations work?
Select a passage, attach a note, repeat wherever needed, then add one instruction that ties them together and send once. Nothing reaches the agent until you send, and the combined turn can direct an edit, a discussion, research, or a change to project guidance.
What can I import and export?
Common manuscript documents import into an ordinary editable project, Scrivener projects migrate in one-way, and exports are polished professional files across the supported formats — including FDX and Fountain for scripts — with your byline and nothing of ours.
Does the full product work on a phone or tablet?
Yes. Narrow screens switch between full-width Editor and Agent views instead of cramming both panes, and switching never loses your draft, your composed message or an active run.
