Key Features of Grammarly (2025 Update)
1. Advanced Grammar & Spell Checker
This is where Grammarly shines the most. It goes beyond the basic corrections of Microsoft Word or Google Docs.
Instead of simply flagging errors, it explains why something is wrong.
Example:
Instead of saying: Incorrect verb, Grammarly says:
“Use the correct verb tense to match the timeline of your sentence.”
This makes it excellent for people trying to improve their writing long-term, not just avoid mistakes.
2. AI-Powered Rewriting & Tone Transformation
One of Grammarly’s strongest 2025 features is its “Rewrite with AI” tool.
You can instantly transform sentences to sound:
- More formal
- More friendly
- More confident
- More professional
- More concise
- More persuasive
For people writing business emails or sales content, this is a game-changer.
Example:
Original: “I’m not sure if you received the file.”
Rewritten: “I wanted to follow up to confirm you received the file.”
Cleaner. More respectful. More professional.

Grammarly’s plagiarism detector checks your writing against billions of online pages and academic sources.
This feature benefits:

While it’s not as advanced as full AI chatbots, it’s extremely useful inside your writing workflow.
