Grammarly
Catches your writing mistakes everywhere you write, before anyone else sees them
- Freemium
- New
Grammarly is the writing assistant that works where you already write — Gmail, Google Docs, LinkedIn, Word, Slack, and nearly every text box in the browser. You don’t open it; it’s simply there.
It predates the current AI wave by years and adapted to it rather than being replaced by it. The distinction that keeps it useful: chatbots generate text, Grammarly fixes text you’re already writing, in the moment you write it.
What sets it apart
- Everywhere by default: browser extension, desktop app, mobile keyboard, Word and Outlook add-ins
- Real-time correction as you type, so errors never reach the send button
- Tone detection that tells you when a message reads as harsher or more casual than you intended
- Full-sentence rewrites on Pro when a sentence is clumsy rather than incorrect
- Plagiarism checking against published sources, useful for academic work
- Snippets and style guides so a team writes with a consistent voice
How to use it
- Install the browser extension or desktop app from
grammarly.com - Write as normal — underlines appear under issues as you type
- Click a suggestion to accept it, or dismiss it if it’s wrong
- Set your goals (audience, formality, intent) so suggestions match the context
- Use the rewrite feature on sentences that are correct but awkward
Tips for better results
- Set the goals for each document. A cover letter and a Slack message should be judged differently, and Grammarly only knows if you tell it
- Ignore it deliberately sometimes. It pushes toward safe, neutral prose; good writing often breaks its rules on purpose
- Watch the tone detector on emails — it catches “this reads as annoyed” before you send something you regret
- Turn it off on sensitive documents rather than trusting settings you haven’t read
- Treat the AI detector as a hint, never as proof
Who it’s for
A good fit if you write professional English daily, aren’t a native speaker and want a safety net, send a lot of email, or are a student who needs plagiarism checking.
Not a good fit if you write primarily in Arabic (it offers nothing), need to generate long-form content from scratch, or already run everything through a chatbot before sending.
Limits and warnings
English only. No Arabic, and no sign of it coming.
Monthly billing is steep — $30 a month against $12 on the annual plan. If you’re going to pay, pay annually.
It flattens voice. Accept every suggestion and your writing gets correct and characterless. Push back on the ones that sand off something deliberate.
Alternatives
ChatGPT and Claude both correct and rewrite text well and handle Arabic, though neither works invisibly inside every app. Notion AI covers editing if your writing already lives in Notion.

❓ Frequently Asked Questions
Is the free plan enough?
For most people, yes. Free covers grammar, spelling, punctuation, and tone detection across every app the extension supports, plus 100 AI prompts a month. Pro adds full-sentence rewrites and plagiarism detection. If you write professionally in English every day, Pro earns its cost. If you're fixing emails, free is fine.
Does it support Arabic?
No. Grammarly is English-only, and that's unlikely to change soon. For Arabic writing you'll want ChatGPT or Claude with an explicit instruction to correct grammar and style — neither is as seamless, but both handle Arabic well.
Grammarly or ChatGPT for writing?
They solve different problems. Grammarly sits invisibly in every text field and fixes what you're already writing. ChatGPT is where you go to generate or restructure something. Most people who write a lot use both — Grammarly for the constant background correction, a chatbot for the heavy lifting.
Is my writing private?
Text passes through Grammarly's servers to be analyzed — that's how it works. Business and Enterprise plans include stricter data handling. If you write anything confidential, review the privacy settings and consider disabling the extension on sensitive sites.
Does it detect AI-written text?
Pro includes an AI detector, but treat all such tools skeptically. Every AI detector on the market produces false positives, sometimes flagging entirely human writing. Use it as a rough signal, never as evidence.
