What's the minimum tool stack for a new indie author?+
For a bare-minimum budget launch: Google Docs (free writing), ProWritingAid free tier (editing), Canva free (cover design), KDP (publishing, free), and iWrity (ARC reviews, free tier available). You can publish your first book with $0 in tool spend — though Canva Pro ($15/month) and an editing tool ($100/year) are worthwhile upgrades once you're earning.
Is Scrivener worth buying for indie authors?+
Scrivener is worth buying if you write complex novels (multiple POVs, non-linear plotting, series worldbuilding) and you plan to write multiple books. At a one-time fee of around $60, it pays for itself quickly. If you write shorter books or prefer simplicity, Google Docs or Word works fine and costs nothing extra.
Do I need Publisher Rocket to do keyword research?+
Publisher Rocket ($100 one-time) is the most powerful KDP keyword research tool available and is generally considered worth the investment for authors publishing regularly. Free alternatives include Amazon autocomplete (type a keyword and note the suggestions) and the KDP category browser. Publisher Rocket pays back its cost in improved discoverability within your first few launches.
What's the best tool for getting Amazon reviews in 2025?+
iWrity is the leading ARC platform specifically optimized for Amazon reviews in 2025. Unlike generic ARC sites, iWrity matches books to genre-specific readers, tracks review completion, and is fully Amazon TOS compliant. Other options include BookSirens and Hidden Gems, but iWrity's genre-targeting produces higher review conversion rates and better review quality for most authors.
How much should I budget for indie author tools per year?+
A realistic budget for an active indie author: Writing tools $0–$60 (Scrivener one-time), Editing $100–$200/year (ProWritingAid or Grammarly), Cover design $0–$180/year (Canva Pro), Formatting $60–$200/year (Vellum one-time or Atticus), KDP keywords $100 one-time (Publisher Rocket), ARC/reviews $0–$50/month (iWrity), Email marketing $0–$30/month (MailerLite). Total: $300–$1,000/year for a fully equipped author.
Which formatting tool is best for KDP in 2025?+
Vellum (Mac-only, $200 one-time) produces the most beautiful ebook and print interiors and is preferred by most professional indie authors. Atticus ($147 one-time, Windows and Mac) is the best cross-platform alternative with similar features. For authors who only need ebook formatting, Kindle Create is free and surprisingly capable for straightforward novels.
