Plan is the connective tissue of a project. Outline, characters, world building, beats, relationship canvas, research notes, everything you'd otherwise sketch in a notebook or spreadsheet.

Every artifact you make here gets read by the AI tools downstream. Fill in a character once; the line editor knows their voice forever. Add a comp to your research notes; the back-cover drafter and the keyword scout pick it up.

The outline is a stack of chapter cards. Each card has a working title, a one-paragraph summary, the POV character, and any beats you've assigned to it. Drag to reorder; cards renumber automatically.

Cards are connected to chapters in Write, when you write or edit a chapter the matching card updates with a fresh summary on demand. The developmental editor uses these summaries as its big-picture view of the book.

Each character has a sheet with the basics (name, age, occupation, physical description), a voice profile (typical sentence length, vocabulary register, verbal tics), and free-form notes for backstory and goals.

On Loom, the AI assistant can fill in any field you leave blank using the rest of the project as context, typically faster than a full character workshop, then you edit what doesn't feel right. The line editor reads the voice profile when critiquing dialogue; the synopsis builder uses motivations and arcs from the sheet.

World building groups locations, factions, cultures, magic systems, and a project glossary. The glossary is the one most writers reach for first: it's the place to record invented words, made-up institutions, and spellings of proper nouns. The copy editor reads the glossary as the project's style sheet for those terms.

Locations and factions are optional but feed the AI assistant in Write when you ask it to draft a passage set in a specific place.

Beat-sheet templates: Save the Cat, the Story Grid foolscap, three-act, four-act, the Snowflake, the Hero's Journey, and freestyle (blank). Pick one when you create the project or switch later.

Beats live on the same screen as your outline; drag a beat onto a chapter card to anchor it. The developmental editor watches beat placement as a structural-feedback signal.

The relationships canvas is a visual node map: every character is a node, every relationship is a labelled edge. Click an edge to add notes, mark it as evolving, or set the chapter where the relationship turns.

Useful for ensembles and serialised work where you need to see at a glance who knows whom and what's unspoken between them.

Research notes are free-form: pasted text, uploaded reference PDFs, web clips, photo references for locations. Tag notes by chapter, character, or topic; filter from any other studio.

The AI assistant in Write can be pointed at a specific research note as ground truth, useful for historical fiction or anything where you don't want the model to invent period details.

Plan's AI assistant is conversational rather than generative, it answers questions about your project rather than writing prose. "Where did I introduce Mira's mother?" "What's the conflict between the Council and the Reach?" "Which chapters have no scene set outside?"

It reads every Plan artifact in the project plus the chapter summaries from Write. It does not have access to the full manuscript text, that's the Write assistant's job, so it's fast and cheap to talk to.
