Common questions

Everything you need to know

No. Every purchase is one-time. Buy credits once, they never expire. Buy the Essentials Bundle once, own it forever. No subscriptions, no recurring charges.
Kindle (MOBI/KFX) works on Amazon devices only. EPUB works everywhere else (Apple Books, Kobo, Barnes & Noble). Our tools support both.
Yes. The EPUB Validator and Metadata Builder work immediately — no account, no email, no credit card. Just open and use.
Credits are used for AI-powered tools only. Each AI tool costs 1–3 credits per run. Buy a credit pack, use them whenever you want — they never expire. Logic tools (formatting, TOC, etc.) don't use credits at all.
Yes! Manuscript Cleanup and Style Sheet Auditor both offer a free 500-word sample. See real AI results on your own text before buying a single credit.
Claude Haiku by Anthropic — fast, accurate, and cost-effective for formatting and analysis tasks.
Yes — 7-day money-back guarantee on any purchase. Email us and we'll sort it.
You own all 5 logic tools forever. Use them as many times as you want, no limits, no expiry. Future updates to those tools are included.
Full Access ($9.99) gives you all 5 logic tools plus 30 AI credits. That's the Essentials Bundle ($4.99) + more than a Starter Credit Pack ($7.00) — for less than buying them separately.
You need an account to use paid tools so we can track your credits and tool access. But the two free tools (EPUB Validator and Metadata Builder) never require an account.
