The marketing toolkit spans three studios, Sell (cover, back cover, one-pager, keywords, audiobook), Pitch (agents, publishers, queries, submissions), and Market (comps, plan + budget, reviewers, partnerships). They share data freely: a comp you save in Market shows up in the Sell back-cover drafter and the Pitch query-letter writer.

Manual versions of the list-builders and trackers ship on Spool; AI-curated search and drafting starts on Loom.

Open Sell → Cover. The designer reads your genre, comps, synopsis, and any reference images from your Media gallery as its brief. Hit "Generate concepts" to get six rough directions, then drill into any one to iterate on layout, typography, and palette.

Finished designs drop into your project's Media gallery automatically and become eligible to feed every downstream tool (one-pager, press packet, retail listing previews).

Generation is on Loom and Tapestry; on Spool you can upload your own cover and use the rest of the marketing tools.

Drop any cover (yours, a competitor's, a thumbnail from your comp set) onto the rater and get a structured critique against a six-category rubric: genre signaling, focal hierarchy, type, palette, market-fit, and first-impression.

The rater is most useful between iterations, generate, rate, tweak, rate again. Numerical scores aside, the prose notes are usually what shifts the next iteration meaningfully.

Each query draft starts from your synopsis, comps, and author bio, already filled in from the rest of your project. The drafter then personalizes the letter for the specific agent: opening line tuned to their stated taste, comp titles reordered for their list, conference references where relevant.

You read the draft, edit anything that sounds like a template, and send. The tool never sends on your behalf, the click is always yours.

The comp set is a curated list of five-to-ten comparable titles. The finder surfaces candidates from recent releases in your genre and audience; you save the ones that fit, with your own notes on why.

Every other tool reads the saved set: the cover rater uses it for genre signaling, the back-cover drafter cribs structure, the keyword scout pulls retail keywords from the set, the reviewer finder filters to people who covered your comps.

Three pieces of copy that every other tool needs. Short and long versions of each, generated from your manuscript and editable.

Synopsis: spoiler-included, used for query letters and editor submissions. Back cover: spoiler-free, used for retail and the print interior. Author bio: short (one sentence), medium (one paragraph), long (one page), the right length auto-picks per output.

All three live as the single source of truth, so an edit anywhere shows up everywhere.

A press-ready marketing one-sheet: cover, comps, hook, audience, author bio, contact, and a clean read-on-paper layout. Auto-built from the synopsis, comp set, bio, and cover; export to PDF for sub-rights conversations and press kits.

Tune any section before export, the auto-build is a starting point, not a constraint.

The reviewer finder pulls candidates from BookTok, YouTube, Goodreads, indie blogs, and Substack, filtered by your genre, audience, and recent activity. For each it returns the channel name, recent comparable reviews, follower size, and the best public contact path.

Results export to spreadsheet for outreach tracking, or push directly into the outreach organizer (see Market → Plan & budget) for status tracking.

AI-curated search is Loom and Tapestry; Spool gives you the same database with manual filtering.

The partnerships database surfaces aligned podcasts, newsletters, indie bookstores, festivals, and local press by your home base and genre. Each entry is a pitch-friendly profile: what they book, who their audience is, how to reach them, what they're looking for next.

Same shape as the reviewer finder, search, filter, save, outreach.

The keyword scout generates Amazon KDP keyword strings and retail-ad-friendly phrases by reading your comp set, back cover, and category. It validates each candidate against current search volume in your category, so you don't waste a slot on a keyword nobody types.

Output is seven KDP-ready strings plus a longer list of retail-ad phrases. Edit any of them and the validation re-runs.

Month-by-month marketing plan with a connected line-item budget. Pre-launch through launch quarter; move money between weeks, mark line items as done, slipped, or cancelled.

Templates for the budgets writers actually run: zero-dollar guerrilla, ~$500 indie, ~$2,500 hybrid push, $10K+ publisher-assist. Pick a starting point; tune from there. Post-launch the plan stays around as a memory, your next book's plan can start from this one.
