Grammarly for Indie Authors
Where ProWritingAid, covered in the previous article, is built specifically for the depth a full manuscript needs, Grammarly takes the opposite approach: broad, fast, reliable correctness wherever you happen to be writing. It runs in your browser, your desktop apps, Google Docs, your email client, and your phone's keyboard, catching errors and offering suggestions in the moment, across virtually everything you write. For an indie author, that ubiquity matters most for the writing that surrounds your book — emails to your cover designer, newsletter copy, marketing materials, reader correspondence — rather than the manuscript itself.
Core Features
Real-time, in-the-moment correction across virtually every writing surface — browser extension, desktop app, mobile keyboard, and direct integration with Google Docs, Microsoft Word, and email clients
Full-sentence rewrites and tone adjustment — beyond catching errors, Grammarly's AI features (available on the free tier in limited form, expanded on Pro) can rewrite a sentence for clarity, adjust tone, or suggest a different phrasing entirely
Plagiarism detection — a Pro-tier feature that checks your writing against a broad database, useful as a sanity check on marketing copy or other content before publication
Style guides and brand tone settings — useful for keeping your marketing voice consistent across multiple pieces of content over time, particularly relevant for an author building a recognizable brand voice in newsletters and social copy
Clear, accurate suggestions presented with color-coded categories and plain explanations — widely regarded as having a gentler learning curve than ProWritingAid's denser report system
Where Grammarly Genuinely Helps
Day-to-day business writing — emails, social captions, ad copy, website content, and correspondence with your cover designer, formatter, or other collaborators, where speed and broad coverage matter more than deep manuscript-level analysis
Authors who move between many different writing surfaces throughout their day and want consistent error-catching everywhere, rather than needing to paste text into a separate tool
A final, fast correctness pass on a piece of marketing copy or newsletter content before it goes out, catching typos and awkward phrasing quickly
In direct side-by-side testing referenced by multiple reviewers, Grammarly catches more straightforward grammatical and spelling errors in a given passage than ProWritingAid does — for pure error-catching, it has a real, demonstrated edge
Where Grammarly Falls Short for Authors
It lacks the deep, manuscript-specific structural reports ProWritingAid offers — there's no equivalent to pacing analysis, dialogue tag tracking, or repetition reports built for book-length fiction; Grammarly's suggestions trend toward a generic, broadly readable style rather than craft-specific feedback
Authors with a strong, deliberately distinct authorial voice sometimes find Grammarly's constant suggestions to simplify or smooth out phrasing more of a friction point than a help — the tool doesn't distinguish between an actual error and an intentional stylistic choice
For a full manuscript, many authors and reviewers recommend using ProWritingAid for the deep structural and style pass, and Grammarly for a final, fast correctness check — rather than relying on Grammarly alone for book-length creative work
⚠ As with every editing tool in this section, Grammarly's suggestions are recommendations, not commands. Especially for fiction with a deliberate voice, evaluate each suggestion against your actual creative intent before accepting it — a tool optimized for broadly readable, generically clear prose isn't always optimized for your specific book.
Free vs. Paid
ScribeCount Digital Assistant: A Note on the Difference
Grammarly checks and improves the text you're actively writing; it has no connection to your publishing business or sales data. The ScribeCount Digital Assistant, covered in the Virtual Assistants section and ScribeCount Features, is a separate tool focused on your live, connected ScribeCount account. An author might reasonably use Grammarly while drafting a newsletter, then later ask the Digital Assistant how that same newsletter's campaign actually performed — two different tools for two different stages of the work.
Conclusion
Grammarly's value to an indie author is breadth and speed, not manuscript-level depth — it's the tool you'll use constantly across everyday business writing, while ProWritingAid, covered in the previous article, handles the deeper structural pass a full manuscript benefits from. Many authors reasonably use both, for different stages and different kinds of writing. The next article in this section covers Hemingway Editor, a narrower, readability-focused tool with one of the more debated value propositions in this entire section.
