TomeScout

TomeScout Toolkit helps self-published authors prepare and price a book for Amazon KDP, right inside Claude.

Ask in plain English — "fill my seven KDP keyword boxes", "check my book listing before I publish", "what royalty do I earn at $4.99?", "how many copies does a #5,000 rank sell?" — and TomeScout answers:

• keyword_boxes: packs your phrases into KDP's seven 50-character keyword boxes, drops words your title already covers and refuses other authors' names, trademarks and Amazon programme names.
• check_listing: title, subtitle, description, keywords and categories against KDP's published metadata guidelines, with the KDP help page for each issue.
• royalty_calculator: eBook 70% vs 35% in 13 Amazon stores with the 2026 price bands, delivery costs and VAT; paperback printing cost and royalty; Kindle Unlimited earnings.
• bsr_to_sales: a Best Sellers Rank turned into a range of daily and monthly sales from two public models.

Every tool calculates from what you provide plus KDP's published guidelines and price tables; nothing is fetched from Amazon or any other website. Results render as interactive tables and cards, and every estimate comes with its range and caveats. TomeScout is independent and not affiliated with Amazon.
