One Platform.
Everything you need to:
WriteLoom is the end-to-end workspace for writers ready to take their craft to the next level.
Each step of the process talks to all the rest, so your synopsis flows into your back-cover copy, into your one-pager, into the personal note you send an agent.
Outline by act, draft by scene.
Plan the next chapter in the outline view. See the whole arc in the storyline view, every act, every beat, every scene. Drag, reorder, and watch the story take shape before you write a word.
Learn moreCharacters and worlds that remember themselves.
Character profiles, world entries, and a relationships canvas, all linked to the manuscript so your edits stay grounded in your story's facts. Nothing forgets your book between sessions.
Learn moreA meticulous editor, not a co-writer.
The editor handles your prose. The AI assistant flags weak phrasing, pacing problems, and continuity slips, without rewriting a single sentence for you. Your voice stays yours.
Learn moreCovers that test against the real shelf.
Generate variants, iterate on typography and palette, then score every option against the comps in your genre, before a single reader sees the book.
Learn moreFind the right agent, draft the right letter.
A curated database of literary agents and publishers, filtered to your genre and recent sales. Draft and tailor query letters with full project context, then track every submission in one place.
Learn moreA launch plan with a budget that adds up.
Comp curation, reviewer outreach, a marketing calendar with line-item budget tracking, and a timeline that connects every launch decision back to the manuscript it's selling.
Learn moreSix glimpses. Another 30+ tools live across the eight studios.
Chapter I·The eight studios
Where a book actually lives.
Most writing tools stop at the draft. WriteLoom keeps going, through the cover, the comps, the query letter, the reviewer outreach, the marketing calendar. One project; the whole arc.
Write
Edit
Media
Design
Pitch
Sell
Market
Chapter II·AI on your terms
Love it, hate it, or somewhere in between.
We don't care whether you hand the AI the wheel, want it as a quiet hand, or skip it entirely. Pick the tier that matches how much AI you'd actually use, and turn the rest off.
If you love AI
On Loom, hand the Write assistant your plan and have a complete first draft in a day. AI editors clean up after; the marketing studios draft your query letter, back cover, and reviewer outreach from the same project. You stay editor-in-chief; the AI does the typing. 1M AI tokens a month, with $10 top-ups for another million when you need more.
If you want a light hand
Spool opens every AI feature on a small monthly allowance, 100K AI tokens and 10 image generations a month, no top-ups. Enough to draft a tricky chapter, run a handful of agent or comp searches, generate a cover or two, and see which features earn a place in your process. Many writers use it exactly this way: a quiet workspace with AI as an occasional second pair of hands, not a co-author. And every AI feature can still be turned off entirely if you'd rather skip it.
If you hate pitching
This is the part of the platform writers ask for most. The Pitch studio handles agent + publisher research and drafts personalized queries from your synopsis and bio on both Spool and Loom; Loom just has 10× the AI budget if you're running serious volume. Either way: drastically less spreadsheet.
Chapter III·Where to begin
Start anywhere. Land anywhere.
Whether you have a glimmer of an idea, a half-finished draft, or a manuscript that's ready to send to the presses, there's a doorway in. Open Studio 01 and start from a blank outline, or bring the book you've already written by exporting an EPUB from your current writing platform or uploading a Word document. The studios you don't need yet sit quietly until you do.
Just an idea
Mid-draft
Ready to ship
Migration paths: .docx (Word), .epub (any writing platform that exports one), .pdf (text or vision OCR), and .txt. More detail in the FAQ below.
Chapter IV·What makes WriteLoom different
Drafting is one third of writing.
Every other writing tool tops out at the manuscript. You finish a draft and start over in five new tools: a cover designer here, an agent spreadsheet there, a keyword tool, a reviewer list, a launch calendar. By the third tool you have lost the thread of your own work.
WriteLoom treats a project as one continuous thing. The synopsis you wrote in Plan shows up, already filled in, when you draft your query in Pitch. The comps you chose in Market quietly inform the cover rater in Sell. The author bio you set once travels into every outreach letter.
You stay creative. The platform handles the bookkeeping.
Chapter V·Who it's for
Made for fiction and non-fiction.
Those are WriteLoom's two homes, from novels and short fiction to memoir, narrative non-fiction, and essays. The same project adapts to plenty more, too: pick a work format when you create a project and the editor, toolbar, export pipeline, and relevant studios change to match.
The full range
Chapter VI·Reception
Built by writers, not marketing tech bros.
Shaped by working writers in our beta program; here's what they actually said. We've shortened their names at their request — these are real beta writers giving honest feedback, not paid endorsements.
The reason I stuck around was the Pitch studio. I had 40 agent spreadsheets going. Now I have one.
I use it mostly with AI off. The Plan studio and the relationship canvas held my whole 220k-word trilogy without going wobbly past 80k like other tools do.
The line editor caught my voice; it didn't replace it. That's the whole reason I trust this thing.
I feel like I can finally organize things. This works with my ADHD brain.
Everything about this… Chef's kiss!
This is so much better than all those other tools. Get rid of those!
Chapter VII·The fine print, made plain
Your work. Your pace. Your exit.
WriteLoom is built on a principle most writing tools quietly avoid: you own everything you put in, and you can leave at any time.
AI is optional, not central
Every AI feature can be turned off. The organization studios, Plan, Media, Design, Market, work as a structured workspace with or without a model in the loop.
AI usage is included
No per-call billing, no separate AI bill. The one exception is audiobook generation, which uses your own ElevenLabs API key, they charge by character, and most writers prefer to control that line item directly.
Export anywhere, anytime
PDF, EPUB, .docx, .md, manuscript, cover, comp set, marketing plan, all yours, all portable, any time. You're never locked in: your book lives in standard formats you can take with you whenever you want, so you stay because WriteLoom earns it, not because you're stuck.
No training on your work
Your manuscript is never used to train any model. The only thing that leaves WriteLoom is the context a feature needs, sent to our AI providers, Anthropic (Claude) and OpenAI, under contracts that forbid training on it; audiobook narration uses your own ElevenLabs key. Nothing is sold, mined, or used to improve a system that isn't yours.
Cancel without losing your book
If you cancel a paid plan, you drop back to the free Thread plan. Your account and manuscripts stay with you; only the paid studios pause. Inactive Thread accounts (no sign-in for 6 months) have their projects removed.
Chapter VIII·Sustainability
One oak per writer, every year.
Software has a quiet carbon cost. The servers that hold your manuscript, the data centers that route your AI calls, the storage that keeps every revision , none of it is free. We don't pretend it is. We do try to leave the ledger in the green.
Figures are estimates, not promises. We publish the receipts in our annual report, coming with the first full calendar year.
Free to start writing. Pay when you're ready for more.
Four plans named for the stages of weaving a finished book, Thread, Spool, Loom, Tapestry. Thread is free forever. AI is included on every plan.
Is this AI going to write my book for me?

Is the free plan actually useful, or just a teaser?
Is this only for novelists?

I already have a draft, can I bring it in?
Will my writing be used to train AI?
