ABOUT GRAMMARLY
OVERVIEW
- Who is it for?
- Professionals, students and teams who write in English across email, documents and the browser and want correction where they already type.
- Problem
- Writing happens across dozens of applications, and a checker that only works inside one editor gets bypassed exactly when it matters.
- Solution
- Grammarly runs as browser extensions, desktop apps and mobile keyboards so corrections appear in whatever tool is in use, and layers tone detection, rewriting and generative prompts on top. Free covers grammar, tone and 100 AI prompts; Pro is 12 USD monthly with a 7-day trial.
- What makes it unique
- Distribution rather than the model - Grammarly is present in nearly every text field on the machine, which is why it survives as a habit where standalone editors do not.

- Real-time grammar, spelling and punctuation correction
- Clarity and conciseness rewriting suggestions
- Tone detection and adjustment
- Generative AI writing prompts
