How Grammarly Works — and When Kids Should (and Should Not) Use It
What Grammarly does
Grammarly is an AI writing assistant with tens of millions of daily users, many of them students. It checks spelling, grammar, punctuation, clarity, and tone in real time, working inside Google Docs, Word, email, and most places kids write.
Think of it as a spell-checker that grew up — it catches not just typos but unclear sentences and awkward phrasing, with explanations for its suggestions.
When it genuinely helps
For a child who has written their own draft, Grammarly is a brilliant editor. It catches mistakes they would miss, explains why something is wrong, and helps them learn patterns over time.
It is especially valuable for kids who struggle with spelling or mechanics — including those with dyslexia — because it removes a barrier that can otherwise overshadow good ideas. The child still writes; Grammarly polishes.
When it gets in the way
Grammarly's newer AI can also generate and heavily rewrite text. For a young writer, leaning on that crosses from editing into outsourcing — the writing stops being theirs.
There is also a subtler risk: accepting every suggestion without thinking. Good writing sometimes breaks rules on purpose, and a child who clicks 'accept' on autopilot never develops their own judgement or voice.
Age and the right settings
Grammarly is really designed for older students and adults. For younger children, a simpler built-in spell-check is often plenty, with Grammarly introduced as writing gets more serious in the upper years.
If your child uses it, encourage them to read each suggestion and decide rather than mass-accept, and lean on the corrective features rather than the generative ones.
The bottom line
Used as an editor for the child's own writing, Grammarly is a genuinely helpful learning tool — fast, instructive, and confidence-building. Used as a rewrite button, it undermines the very skills writing is meant to build.
The rule is the same as for all AI writing help: the words and ideas should be your child's; the tool just helps them polish what they made.
Frequently Asked Questions

It's really designed for older students and adults. For younger children a simple built-in spell-check is usually enough; introduce Grammarly as writing gets more serious in the upper years.
When kids use its generative AI to write or heavily rewrite text, the work stops being theirs. Accepting every suggestion on autopilot is also a risk — it prevents children from developing their own judgement and voice.
