Question 1

What's the difference between EPUB and Kindle format?

Accepted Answer

Kindle (MOBI/KFX) works on Amazon devices only. EPUB works everywhere else (Apple Books, Kobo, Barnes & Noble). Our tools support both.

Question 2

Can I try the AI tools before buying credits?

Accepted Answer

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.

Question 3

What AI model do the AI-powered tools use?

Accepted Answer

Claude Haiku by Anthropic — fast, accurate, and cost-effective for formatting and analysis tasks.

Question 4

What happens after I buy Starter or Pro?

Accepted Answer

You own all 5 logic tools forever — no limits, no expiry, future updates included — plus a pack of AI credits (40 with Starter, 200 with Pro) that never expire.

Question 5

What's the difference between Starter and Pro?

Accepted Answer

Both unlock all 5 logic tools forever. Starter ($19) includes 40 AI credits; Pro ($49) includes 200 AI credits — better value per credit for authors and editors running AI tools regularly.

Question 6

Do I need an account for the paid tools?

Accepted Answer

You need an account to use paid tools so we can track your credits and tool access. But the 5 free tools (EPUB Validator, Metadata Builder, Cover Checker, Word Cleanup Checker, Full Manuscript Mode) never require an account.
