Grammarly’s free tier already catches typos and basic grammar almost everywhere you type. Premium’s pitch is subtler — style, tone, and clarity — which makes “is it worth it” less obvious than it looks.

The short answer

If you write professionally or publish content regularly, Premium is worth it for the clarity and tone suggestions alone. If your writing is casual — texts, quick emails — free covers what you actually need.

What Premium actually adds

Free Grammarly is a spell-and-grammar checker. Premium is closer to a lightweight editor sitting over your shoulder.

When to skip it

Grammarly vs ProWritingAid

If your writing is specifically long-form (a book, a thesis, a long report), ProWritingAid’s reports are built more for that format — pacing, repetition, and structural feedback across a full manuscript. Grammarly is the stronger everyday, everywhere tool: it runs inline across email, docs, and social, not just inside a dedicated editor. See our breakdown in best software for writing a book.

Who this is not for:

Casual writers who've never felt limited by free. Paying for style and tone suggestions you don't need is not worth it.

Long-form fiction or academic writers. A book-focused tool like ProWritingAid may serve that specific need better than Grammarly's more general, everyday focus.

Frequently asked questions

Is Grammarly Premium worth it, or is free enough?

Free Grammarly catches spelling, basic grammar, and punctuation, which is enough for casual writing like emails and social posts. Premium adds style and clarity suggestions, tone detection, and vocabulary enhancement — worth it if you write professionally or publish regularly, where those refinements actually matter to the reader.

How much does Grammarly Premium actually cost?

Pricing is tiered and cheapest when billed annually, working out to roughly $12/month; monthly billing costs meaningfully more per month. Grammarly also offers Business plans for teams, priced per seat.

Is Grammarly Premium worth it if I already use ChatGPT or Claude?

They solve different problems. Grammarly runs inline, real-time checks as you type anywhere — email, Google Docs, Slack — without you having to copy and paste. ChatGPT/Claude are better for heavier rewriting or generating content from scratch. Many writers use both: a general assistant to draft, Grammarly to polish everywhere else.
