The best software for self-publishing authors is a small, well-chosen set of tools rather than one magic app: somewhere to write, a way to edit, a formatter, a cover solution, a publishing platform, an email service and basic security. Most authors can start with free or low-cost options in every category and upgrade only when a tool saves real time or earns real money.

This guide includes a few product links near the end. As an Amazon Associate, Freyja Publishing earns from qualifying purchases, at no extra cost to you.

This hub maps the whole author toolkit, from drafting to audiobooks, with neutral comparisons of the main options in each category, the questions to ask before you pay for anything, and links to every detailed guide on this site about tools, AI and publishing technology. Use it as a starting point, then follow the links for depth.

At a glance

• You need tools for seven jobs: writing, editing, formatting, covers, publishing and distribution, marketing (email and website), and protecting your accounts.
• Free options exist for almost every job. Pay when a tool clearly saves hours per book, improves quality readers notice, or unlocks income.
• AI assistants are useful for planning, research, feedback and marketing copy, but they do not replace a human editor or your own voice, and platforms have disclosure rules.
• One-time purchases often beat subscriptions for authors who publish regularly; prices and models change, so check current pricing before buying.
• Security is part of the toolkit: a password manager and two-step verification protect your royalties.

Writing and drafting tools

Any word processor can produce a novel. The question is how well it handles long documents, research notes, revisions and backups. Google Docs is free, works on any device and saves automatically to the cloud, which makes it popular for collaboration with editors and beta readers. Microsoft Word remains the standard file format editors and formatters expect. Scrivener is built for long-form projects: it splits a manuscript into scenes you can rearrange, keeps research alongside the draft and can compile to several formats, though it has a learning curve. Atticus combines a writing space with formatting, which suits authors who want one app from draft to file.

Whatever you write in, keep at least two backups in different places, one of them off your main computer.

• How to Build a Writing Routine That Actually Works covers the habits and daily targets that matter more than any software choice.
• How to Plan a Book Series That Builds Loyal Readers explains how to plan series arcs, the job outlining tools are designed to support.

Editing tools and services

Editing has two layers: software that catches surface problems, and people who catch everything else. Grammar and style checkers such as ProWritingAid and Grammarly flag spelling, grammar, repeated words, overused phrases and readability issues. ProWritingAid is often chosen by fiction writers for its reports on pacing, dialogue tags and sentence variety; Grammarly is widely used for general writing and integrates into many apps. Both offer free tiers with limits and paid plans; check current pricing and whether a plan suits manuscript-length documents.

No software replaces a human editor for structure, character, plot logic and voice. The guides below explain how to do both well.

• Editing Your Work: A Self-Editor’s Guide sets out a self-editing process for catching the errors professionals look for before you pay anyone.
• Finding the Right Editor: A Complete Guide explains developmental, line, copy and proofreading edits, and how to judge an editor’s sample.

Formatting software

Formatting turns a finished manuscript into an ebook file and a print-ready interior. The three tools authors compare most often are Vellum, Atticus and Kindle Create. Vellum runs only on Mac and is known for polished default typography. Atticus works in a browser or as an installed app on Windows, Mac, Linux and Chromebook, and includes a writing environment. Kindle Create is Amazon’s free tool and is simple, but its main output (a KPF file) works only on KDP; it can also export EPUB for straightforward reflowable books. Draft2Digital’s conversion and layout tools are free to use, and its own FAQ says you can download the finished EPUB or paperback PDF without publishing through it. At the time of writing (October 2026), Vellum and Atticus are both one-time purchases rather than subscriptions; prices change, so check each vendor’s site. For complex layouts such as picture books, cookbooks and heavily illustrated non-fiction, layout software or a professional formatter is often a better fit.

• The Ultimate Guide to Ebook Formatting covers EPUB and KDP file requirements so your digital book displays properly on every device.

Covers and marketing graphics

Readers judge books by their covers, and so do advertising platforms. For the cover itself, the main choices are a custom cover from a professional designer, a premade cover (a ready-made design customised with your title and name), or designing your own. Self-designed covers are the riskiest option unless you have real design skills and know your genre’s conventions. For social posts, ads and promotional images, Canva and BookBrush are common choices; BookBrush is built specifically for book mock-ups and author promotion, while Canva is a general design tool with author-friendly templates.

If you are considering AI-generated imagery, check each retailer’s content rules and the image tool’s licence terms, and remember that copyright treatment of AI-generated images is still unsettled in many countries.

• Choosing a Professional Book Cover Designer explains how to brief a designer, what to expect and how to spot a cover that will sell.

AI tools for authors

AI assistants have become a standard part of many authors’ toolkits. Used well, they help with brainstorming, outlining, research summaries, consistency checks, feedback on drafts, blurbs, metadata ideas and marketing copy. Used carelessly, they produce generic prose, invent facts and can flatten an author’s voice. The main general-purpose assistants (ChatGPT, Claude and Gemini among them) differ in how much text they can handle at once, how they handle tone, their image features and their privacy settings, and all of them change quickly. Check each provider’s current data and training settings before pasting in unpublished work.

Platforms also have rules. Amazon KDP, for example, requires you to tell it about AI-generated content (text, images or translations created by an AI tool) when you publish or republish a book, and counts content as AI-generated even if you edited it substantially afterwards. AI-assisted work, where you created the content yourself and used tools to brainstorm, edit or check it, does not need to be disclosed. Read the current policy wording on each platform you publish to.

• How AI is Transforming Self-Publishing is the broad overview of where AI helps across planning, editing, covers, metadata, marketing and audio, and where human judgement still matters.
• The Best AI Writing Tools for Authors compares how ChatGPT, Claude and other assistants can support brainstorming and editing, with practical examples.

• The Claude Referral Program explains what authors and publishers need to know about how the programme works.

Audiobook production tools

Audiobooks can be produced three main ways: narrating yourself, hiring a professional narrator, or using AI narration. Self-narration needs a quiet space, a good microphone and free or paid audio editing software, plus significant time. Professional narration offers the highest quality and is often arranged through marketplaces such as ACX (for Audible) or through distributors such as Voices by INaudio, which took over the wide-distribution service formerly run as Findaway Voices by Spotify in 2025, with payment models that vary. Spotify for Authors handles distribution to Spotify itself. AI narration options include tools from voice companies such as ElevenLabs, Google Play Books’ auto-narrated audiobooks and Amazon’s Virtual Voice, offered to eligible KDP authors in some marketplaces. Each retailer has its own rules about which AI-narrated audiobooks it accepts and how they must be labelled, so check before you produce.

• How to Produce and Distribute an Audiobook compares self-narration, AI narration and professional studios, and explains distribution options.

Publishing platforms and distribution services

Publishing platforms are tools too, and choosing between them shapes everything else. Amazon KDP is the default starting point for ebooks and paperbacks. IngramSpark reaches bookshops and libraries through the Ingram network. Aggregators such as Draft2Digital and PublishDrive distribute to many stores from one upload (each has its own fee or commission model, so compare current terms), while Kobo Writing Life, Apple Books and Google Play Books let you publish to those stores directly. Kindle Unlimited requires ebook exclusivity to Amazon through KDP Select, which affects which other tools and stores you can use.

• KDP or IngramSpark? compares reach, royalties, print quality, returns and control, with a clear recommendation by situation.
• Book Distribution Channels explains ebook, print and library distribution, including aggregators, and how to combine them.
• Kindle Unlimited Deep Dive covers how KU pays authors and what KDP Select exclusivity costs you.
• Print on Demand vs Traditional Printing compares costs, quality and economics so you can choose a printing method.
• How Much Authors Really Earn From Print-on-Demand works through unit costs, royalties and trim sizes with examples.

ISBNs and book identifiers

ISBNs are not software, but they are part of the technical setup. Some platforms provide free ISBNs that may limit where else the edition can be sold or who is listed as publisher; buying your own from your country’s ISBN agency gives more control. Arrangements and costs differ by country, and in some countries ISBNs are free.

• ISBN Explained: Do You Really Need One? explains when a self-published book needs an ISBN and what a free KDP ISBN means.
• How to Get an ISBN covers ISBNs alongside EAN barcodes and other identifiers publishers use.

Email, website and platform tools

Your email list and website are the parts of your platform you control. Email services built for creators, such as MailerLite and Kit (formerly ConvertKit), let you collect sign-ups, send newsletters and set up welcome sequences; most offer a free tier up to a set number of subscribers, then paid plans. Reader-magnet delivery services such as BookFunnel and StoryOrigin deliver free or advance copies to readers and connect with group promotions. For websites, WordPress gives the most control and flexibility, while hosted website builders are simpler to set up. Whatever you choose, use your own domain name so your address stays the same if you move platforms.

Market research and sales tracking

Research tools help you understand categories, keywords and competing books; tracking tools show what is actually selling. Many authors start with free methods: browsing Amazon bestseller lists in their genre, noting cover and blurb trends, and checking retailer dashboards. Paid keyword and category research tools, and dashboards that combine sales from several stores, can save time once you have a backlist or sell wide. Be wary of any tool that claims precise sales figures for other authors’ books; most estimate from rankings.

• Market Research for Authors explains how to spot saturated niches and read trends before they peak.
• How to Measure Self-Publishing Success covers the metrics worth tracking, such as read-through and acquisition cost.

Security tools

Your KDP, distributor, email and bank accounts hold your income. Account takeovers, phishing emails that imitate publishing platforms, and lost access to old email addresses are real risks for authors. A password manager, two-step verification on every publishing and payment account, and a secure recovery email are the essentials, and most of these are free.

• Online Security for Authors is a one-afternoon security setup covering passwords, two-step verification and safer use of public Wi-Fi.

Build your toolkit by stage

You do not need everything at once. This checklist matches tools to where you are.

1. First book. Write in what you already have; use free grammar checks; hire at least a copy editor or proofreader; use a professional or premade cover; format with a free tool or a styled Word file; publish on KDP and decide whether to go wide; set up two-step verification and a free email list.
2. Second and third books (a series forming). Consider a paid formatter to save time on every release and box set; consider a paid style checker; build a simple author website on your own domain; add a reader magnet through a delivery service.
3. Selling wide. Make sure your formatter exports standard EPUB and print PDF; consider an aggregator to manage several stores; consider buying your own ISBNs; consider a combined sales dashboard.
4. Growing backlist. Consider audiobooks for proven titles; upgrade email plans for automation; review whether each subscription still earns its place.

Questions to ask before paying for any tool

• What specific job will this do, and how am I doing that job now?
• How many hours per book will it save, and what is that time worth to me?
• Is it a one-time purchase or a subscription, and what happens to my files if I stop paying?
• Does it work on the computers and devices I actually use?
• Can I export my work in standard formats (DOCX, EPUB, PDF, CSV) if I leave?
• Is there a free trial or refund period long enough to test with my real manuscript?
• Does it work in my country, currency and language, and does it meet my retailers’ requirements?
• For AI tools: what are the privacy and training settings for my unpublished work?

Common mistakes

• Buying tools before finishing the book. Software does not write chapters. Finish a draft before investing in a full toolkit.
• Stacking subscriptions. Small monthly fees add up. Review subscriptions every few months and cancel those you do not use.
• Treating AI as an editor. AI can flag problems and suggest changes, but it can also introduce errors and generic phrasing. A human editor still matters.
• Locking yourself in. Formats that only work on one platform make it harder to change strategy later.
• Skipping security. Losing access to a KDP or email account can stop royalties and sales; two-step verification takes minutes.
• Trusting old reviews of tools. Features and prices change often. Check the vendor’s current information and test with your own work.

Frequently asked questions

What software do I need to self-publish a book?

At minimum, a word processor, a way to produce ebook and print files (which can be a free tool such as Kindle Create or Draft2Digital’s formatter), a cover, and accounts on the platforms you will sell through. Everything else, such as style checkers, paid formatters and email services, can be added as you grow.

Can I self-publish using only free tools?

Yes, for the software side. Free word processors, free formatting tools, free platform uploads and free email tiers cover the basics. The areas most worth paying for are professional editing and a professional cover, because readers notice them.

Is Scrivener better than Word for writing a novel?

Scrivener is better at organising long, complex projects with many scenes and research notes, while Word is simpler and is the format editors expect. Many authors draft in Scrivener and export to Word for editing. Try both before deciding.

Should authors use AI tools?

Many authors use AI for brainstorming, outlining, research summaries, feedback and marketing copy while writing the book themselves. Check each platform’s disclosure rules, keep your own voice, and verify any facts AI provides.

What is the best formatting software for Windows?

Vellum is Mac-only, so Windows authors usually choose Atticus, Kindle Create (for Amazon-only books) or Draft2Digital’s free formatter. Test with your own manuscript, and see the ebook formatting guide linked above for file requirements.

Do I need a website as a new author?

It is not essential on day one, but a simple site on your own domain gives readers a permanent place to find your books and join your list. Many authors start with a basic page and expand it as their backlist grows.

A good author toolkit is lean, matches your stage and earns its place. Start with free options, invest first in editing and covers, add paid software when it clearly saves time or opens new income, and keep your accounts secure.
