AI tool Grammarly for beginners: what's free and what Pro adds

What the free plan does

Grammarly's plans page lists three things on Free:

• Mistake checks. Spelling, grammar and punctuation as you type.
• Tone detection. It tells you how your writing comes across.
• 100 AI prompts a month. A prompt is a request to generate or rework text, like "make this shorter."

For most personal email and everyday writing, that covers it.

What Pro adds

Prices and features are from Grammarly's plans page on Nov 11, 2026. There is also an Enterprise plan, priced through sales.

How it differs from a chat assistant

With a chat assistant, you paste your writing in and ask for help. Grammarly works the other way: it sits where you already write and marks things as you go. You don't have to remember to use it. Many people use both, a chat assistant for drafting and Grammarly for the final pass.

What to try first

1. Install it and write a normal email. See what it flags before you change any settings.
2. Check the tone note before you send something that matters, like a complaint or a request.
3. Spend a prompt. Select a clumsy paragraph and ask it to make it clearer.

The Pro trial reminds you by email two days before it ends, according to the plans page. Put the end date in your calendar anyway.

When paying makes sense

Pro is worth a look if you write for work every day and want rewrites of whole sentences, or if you need plagiarism checks for school. If you mainly want typos caught, stay on Free. For other ways to get writing help, see AI tools for writing.
