What is Grammarly?
Grammarly is an AI-powered writing assistant that runs across most places people write in English. The current grammarly.com site advertises integrations for browsers (Chrome, Safari, Firefox, Edge), desktop apps (Windows and Mac), mobile apps (iPhone, iPad, Android), Microsoft Office, and Google Docs. The same page states the product is used by 40 million people and 50,000 organizations.
At its core, Grammarly does three things:
- Correctness: flags spelling, grammar, and punctuation issues.
- Clarity: suggests rewrites for wordy, vague, or hard-to-read sentences.
- Tone and style: estimates how a piece will land and suggests adjustments.
The newer product surface also exposes AI agents (a Humanizer agent, an AI Detector, and an AI assistant), a paraphrasing tool, a translator, and a citation generator. Exact agent names and availability change frequently, so check the current pricing page before relying on any specific feature.
For ESL teachers, the practical story is simple: it is one of the few writing tools that meets students where they already write, without requiring a separate ESL-specific platform.
How teachers use it
Grammarly fits well into specific classroom and teacher workflows:
- Cleaning up handouts and slides: run your own worksheet copy through Grammarly before printing or sharing. Catches typos, missing articles, and accidental fragments.
- Modelling revision: paste a student paragraph in class and ask the class which suggestions to accept or reject. Builds editing awareness, not just error correction.
- Short student writing tasks: emails, journal entries, discussion-board posts — anywhere students need fast feedback before submission.
- Low-stakes self-check: students use the free tier to proofread homework before turning it in. Reduces the teacher's correction load on mechanical errors.
- Teacher-produced model texts: write a model paragraph, run Grammarly, then annotate the changes for a grammar lesson.
It is less useful for long-form, content-heavy writing where the feedback you actually want is about argument, evidence, or organization — those still need a human reader.
Is it worth your time?
Yes, with the right expectations. Grammarly is a strong general-purpose writing assistant and a useful tool for ESL classrooms, but it is not an ESL-specific product. It will not magically fix article use, preposition choice, or word order in ways that match what an ESL teacher is trying to teach.
What it does well — fast, in-context feedback on the surface errors that distract from meaning — is genuinely useful for both teachers and students. The free tier is enough to test the workflow. Pro adds rewrite suggestions, tone controls, and the new AI agents, but the price (€12/member/month billed annually at the time of writing) only makes sense if those features will actually be used.
Honest recommendation: use the free Grammarly tier as a classroom writing aid, especially for short student tasks. For deeper, structured ESL writing instruction, pair it with a writing-focused ESL platform like Write & Improve, or a paid curriculum such as ESL Brains or Teach-This.
The honest pros and cons
What works
- Works where teachers already write Browser, Google Docs, Microsoft Office, desktop, and mobile — no separate ESL platform needed.
- Free tier is genuinely useful Catches spelling, basic grammar, and punctuation without paying.
- Instant, in-context feedback Students see suggestions while writing, not after the teacher collects work.
- Wide install base 40 million people and 50,000 organizations use it according to the site — easy to roll out.
- Tone and clarity rewrites Beyond correctness, it suggests rewrites for clarity and tone on Pro.
What doesn't
- Not an ESL-specific tool Common ESL errors (articles, prepositions, word order) are not always caught or explained.
- Pro pricing adds up €12/member/month billed annually — easy to forget the per-seat cost on team plans.
- Can over-suggest Lower-level students may accept changes blindly instead of learning the rule.
- No speaking or listening practice It is a writing tool only; you still need separate resources for the other skills.
- Privacy questions on student work Free and Pro plans process student text in the cloud. Schools with strict data rules should review Grammarly's enterprise terms before classroom rollout.
