A free, nonprofit writing and grammar tool for schools. Students combine sentences, fix errors in passages, practice grammar, and write responses to texts using evidence, getting immediate AI-powered feedback that pushes them to revise rather than giving them the answer. Teachers assign activities, run group lessons and see results. It also hosts official free AP, Pre-AP and SpringBoard writing practice and activities paired with literature, social studies and science.
Our take: One of the safest and best-evidenced writing tools for schools; homeschool families can use it as a teacher too.
| Ages it suits | grades K-12 |
|---|---|
| What its terms say about age | Users must be 13 or older (or the age of consent in their country) unless school staff approve their registration. Students under 13 need their school's consent and approval, and teachers who register students promise they have parent consent or follow the law. (terms) |
| Price | Free, with paid extras. All activities free forever; Premium reports cost $115 a year per teacher, with school and district licenses by quote and free Premium for schools with financial need (USD, Oct 2026). |
| Works on | Web |
| Account | A school account |
| Ads | None |
| In-app purchases | None |
| The AI in it | AI-powered feedback reads students' sentences and tells them what to fix, designed to keep students doing the thinking. |

Does it work?
Quill reports an independent randomized trial by College Board in which students using Quill Connect scored significantly higher than a control group, with large effects; other studies, including a 2025 Leanlab study, are on its research page.

Grammarly
Superhuman (the company formerly called Grammarly) · ages about 13-18 and adults (high school, college)
Useful for teens 13+ who want cleaner writing and will use it as a checker, but parents of kids still learning to write should know how much of the writing it can do for them.
