What Grammarly Does Well
Real-Time Writing Assistant Everywhere
Grammarly works everywhere you write: Chrome extension, Microsoft Word, Google Docs, desktop app, Outlook, LinkedIn, Twitter, Slack. It catches errors as you type, in real time, without switching to a separate editor. This ubiquity is Grammarly’s core strength.
GrammarlyGO (AI Writing Assistant)
Launched in 2023 and significantly improved in 2025, GrammarlyGO is now a full AI writing assistant. You can ask it to rewrite a paragraph in a different tone, generate a response to an email, or adjust the formality of any text. On Premium, this is unlimited.
Tone Detection
Grammarly analyzes the tone of your writing and lets you adjust it with one click. This is genuinely useful for client communications where tone matters.
Non-Native English Speakers
If English is not your first language, Grammarly Premium is one of the best investments you can make. It catches subtle errors that basic checkers miss and explains why something is wrong so you learn over time.
Grammarly Weaknesses
- Not a replacement for a human editor – it misses contextual errors and occasionally gives wrong suggestions
- Privacy considerations – Grammarly reads everything you type
- Can be overzealous – sometimes flags intentional stylistic choices as errors
- Requires internet – most features need a connection

Final Verdict: 8.5/10
