Inside the workflow 05

You write or paste text into Grammarly's editor or browser extension, then review its suggestions for grammar, spelling, and style corrections by clicking to accept or dismiss each one. You need to evaluate each suggestion carefully since the tool catches more errors than basic spellcheckers but sometimes offers style recommendations that aren't actually improvements.

—You must be confident enough in your writing skills to know when to ignore suggestions, as style recommendations aren't always useful
—You catch significantly more errors than basic spellcheckers but have to manually review and decide on each suggestion rather than auto-accepting
—You get powerful grammar and punctuation correction but the company has faced legal issues over controversial AI features that may affect trust in the platform

Illustrative output 06

Prompt

Can you help me improve this email draft to my professor? 'Hey Prof Smith, I was wondering if you could maybe extend the deadline for our research paper because I've been having some issues with my computer and stuff. Let me know what you think. Thanks!'

Output

Here's a revised version: 'Dear Professor Smith, I am writing to request a brief extension for the research paper deadline. I have encountered technical difficulties with my computer that have impacted my ability to complete the assignment on schedule. Would it be possible to extend the deadline by [specific timeframe]? I apologize for any inconvenience and appreciate your consideration. Best regards, [Your name]' Key improvements: More formal tone, specific reason, clear request, professional closing. Note: Grammarly caught 3 spelling errors and suggested removing 'maybe' and 'stuff' for more professional language.

Practical interpretation

Grammarly excels at catching basic errors and improving tone/formality, but users need writing confidence to evaluate which style suggestions to accept or ignore.
