A full pre-launch check on your book idea — market, tropes, characters, cover and comps — with a clear go/no-go before you write a word.
Nine craft measurements across your whole manuscript, one clear scorecard, in minutes. This is your free Reader-Ready Scorecard.
Three severity-ranked findings on your opening 5,000 words — each one quoted from your own prose, as a PDF in minutes. Free, one run per account.
A grounded, big-picture editorial read — every claim anchored to a real moment in your text.
POV, tense, rhythm, diction and a tight watch-word list — reverse-engineered from your own prose.
A data-grounded read on whether your book fits what readers are buying right now — and exactly how to position it to sell.
Hundreds of precise edits, each measured against a Style Sheet reverse-engineered from your own voice.
A full structural teardown — acts, beats, pacing, POV and character arcs, dissected end to end.
Every scene scored keep, fix or cut — with the reason. The worklist for exactly where to spend your next two weeks.
A cinematic single-page author website, designed from your covers and built from your story — yours to host anywhere.
An Amazon-ready blurb tuned to what your exact subgenre is selling this month — two versions, keywords and categories.
Upload your finished series and get every place a later book breaks an earlier one — each with a fix — before readers find it.
Will Amazon shelve your book where readers are looking? Get the exact category, BISAC, keywords, subtitle and rewritten blurb — ready for KDP.
Wrote a bad AI book? Don't polish it — rebuild it. Repeated scenes cut, contradictions resolved, dead chapters deleted. A 3/10 in, a 6 or 7 out.
Multiple reports and a full line edit in one mission — your manuscript read, scored, mapped, edited and cleared for launch.
Real human proofreaders catch the last mistakes and hand you a candid reader's reaction — the final check before launch.

What the Scorecard is measured againstFree
The Scorecard is free and always has been. What makes it worth running is what sits behind it: 725,746 hook mentions extracted from real reader reviews, 149,346 book blurbs analysed for hook, stakes and tone, and 4,293 reader personas built from that data. On this site since June 2026, authors have uploaded 74 manuscripts, run 214 completed critiques and edits, and run 40 free Scorecards. Counted from our own databases on 24 August 2026 — we update these when we re-count and we do not round them up.
The other free tool here is the First-Chapter Autopsy: three severity-ranked findings on your opening 5,000 words, each quoted from your own prose. Every other tool is pay-as-you-go — see all tools.
