Muse doesn't have one mode of engagement. Different moments in the writing process require different kinds of intelligence. Each role is distinct — and every one of them has already read your entire project before you ask anything.
The Editor reads your draft and gives you the feedback a developmental editor would give — but one who has read every chapter, knows every character, and understands where this scene sits in the arc. It notices when a character acts against who they've been established to be. It tells you when a scene isn't doing the structural work it needs to do.
The Editor uses Muse's most capable model and fetches the specific context it needs from your project before responding. It doesn't just read the current chapter — it reasons across your whole manuscript.
Explores possibilities with you — alternative plot directions, character motivations, scene approaches, solutions to structural problems. Always grounded in your established world rather than generating in a vacuum. It knows what's been foreshadowed, what's been established, and what would contradict canon.
The Brainstorming Partner asks questions as much as it suggests answers. Its job is to help you discover where the story wants to go — not to decide for you.
A guided conversation that takes you from a blank project to a complete structural scaffold. Not a form — a conversation. Muse reads what you have, asks one targeted question at a time, and maps the full story arc as each beat locks in. Available at book level, act level, and chapter level.
The frameworks — five-act structure, the Plot Clock, Therefore/But connective tissue — are the engine underneath. The writer never sees them. They just feel the story taking shape.
A guided character development conversation that populates your character's arc profile — their wound, their false belief, their want versus their need, their arc crisis, their transformation. Each field informs how Muse writes and edits that character across every subsequent interaction.
Characters with complete arc profiles are written more consistently. The Editor uses these fields to catch when a character acts out of alignment with who they are.
Reads your entire manuscript in a single pass and produces a structured report of inconsistencies — character detail mismatches, timeline contradictions, lore violations, unresolved plot threads, and worldbuilding conflicts. Run it at any point in production. Run it before a submission.
Most continuity errors in long fiction are invisible to the writer precisely because they've lived with the manuscript too long. The Continuity Checker has no such familiarity — it reads everything fresh, every time.
The role you reach for when you want to write or rewrite prose from the chat window. Ask it to draft a scene, strengthen a passage, rework an ending, or copy-edit a chapter. It knows your document already — you describe what you want, and it makes the changes directly.
The Writer is the everyday companion to the inline Cmd+Enter tool. Where inline writing continues from the cursor, the Writer handles more deliberate, directed prose work — with the full context of your project already in hand.
A research assistant with live access to the web. Ask about historical periods, real-world locations, technical details, science, culture — anything your fiction needs to get right. Results are grounded in current, searchable sources rather than the model's training data alone.
Useful whenever your world touches the real one — for historical fiction, near-future science fiction, thrillers with technical accuracy requirements, or any genre where getting a detail wrong would pull a reader out of the story.
Talk directly with any character in your project. Muse plays them from the inside — consistent with their arc profile and their current arc position. A character who hasn't had their crisis yet doesn't speak with post-crisis wisdom. Discover a character's voice before you write them. Test how they'd react to a plot event that hasn't happened yet.
Arc-position awareness is the key distinction. A character in Act I speaks from inside their lie. A character at the arc break speaks differently. The same person — different moment.
