Software for Self-Published Authors

The apps and services authors use to write a book, publish it and sell it, in one list. Each one has a BookBird Author Score built from what its own site says it does for an author, what it costs and how widely it is used. Nobody pays to be listed.

Prices and data checked October 7–14, 2026 · Author Score computed by a published formula, not paid for · List your tool

Prices in USD from each vendor’s own site, checked October 7–14, 2026. Searches: US Google searches a month for the product’s name, with the change over 12 months. Score out of 10, by one published formula; nobody pays to be listed.

Software by job

A self-published book passes through several kinds of software: something to draft it in, something to plan it, a check on the prose, a formatter for the ebook and print files, a cover, a store to sell it in, and tools to find readers. Each category has its own page with the full ranking and a short guide to choosing.

Free tools for the numbers

Software helps you write and publish the book. For the numbers around it, our free tools work in your browser with no sign-up: the words to pages calculator for page count, the cover calculator for spine width and cover size, and the royalty calculator for what you earn per copy on Amazon.

How the Author Score works

Every score comes from one published formula: author jobs (50 points: the jobs an author needs that kind of software to do, counted only when the vendor’s own site confirms them), cost (25 points: what a year of use costs one author) and adoption (25 points: how many people in the US search for it by name, and the trend). Each product is compared only with others in its category. Nobody pays to be listed, and no score is adjusted by hand.

The formula, step by step, with every product’s points
