How we ranked

We weighed how much each tool teaches you: whether it explains its suggestions, coaches you through the writing process or shows your progress over time. Then we looked at who it's built for, what it costs and where it works.

The seven tools compared

1. ProWritingAid - Best overall for learning

ProWritingAid is a writing analysis tool built around reports, and it does more than any other tool here to explain why a sentence isn't working.

What works: More than 25 reports flag patterns such as overused words, sticky sentences, pacing and repeats across a whole document, which shows you habits that a single correction wouldn't. Click the blue info icon on a suggestion and you get resources that explain the rule behind it. Premium Pro adds weekly live workshops with authors and editors, a library of more than 200 recorded workshops and daily cowriting sprints. It works in Word, Google Docs, Scrivener, browser extensions and its own desktop apps.

What doesn't: The free plan's tight: you can run each line-editing report twice a day on up to 500 words. Premium is $30 a month billed monthly, so annual billing at $10 a month ($120 a year) is much better value. Premium Pro is $36 a month, or $12 a month billed yearly.

Best for: Fiction and long-form writers who'd like to understand their own habits.

2. Grammarly - Best for tracking your progress

Grammarly is the best-known writing assistant, and its paid plans include features built to show you how your writing changes over time.

What works: The writing progress dashboard gives you a Performance Score that tracks the quality of your writing week over week and recommends learning resources based on your top areas for improvement from the previous week. Its AI agents include an AI Grader that gives feedback against your rubric and course information, with an estimated grade, and Reader Reactions, which shows how a reader you've picked might respond to your draft. Grammarly says you can try most of its agents on the free plan. Pro costs $12 a month billed annually, or $30 month to month.

What doesn't: The progress dashboard isn't on the free plan. It's only on Pro, Business, Enterprise and Grammarly for Education. Grammarly's one-click fixes make it easy to accept changes without reading why, so you have to choose to learn from it.

Best for: Students and professionals who want to see measurable improvement over time.

3. Khanmigo Writing Coach - Best for students

Khan Academy's Writing Coach guides students through an assignment from outline to final draft, and Khan Academy says it never writes a word for them.

What works: It works through the stages of real writing, from outline to final draft. Built-in originality checks show teachers each student's writing process. It's free for teachers and their students in the US, and independent learners can sign up for $4 a month or $44 a year.

What doesn't: It's US-only. Independent learners have to be 18 or older and live in the US with a US billing address, and younger students join through a parent or their school. It's built for school assignments more than professional writing.

Best for: Students who want to learn the writing process, and teachers who want them to.

4. ChatGPT Study mode - Best free tutor

ChatGPT's Study mode, launched in July 2025, turns the chatbot into a tutor that answers with questions.

What works: It uses Socratic questions, hints and knowledge checks, so you can paste in a draft and work out what's wrong with it yourself. OpenAI launched it for Free, Plus, Pro and Team users.

What doesn't: It's a set of instructions layered on top of ChatGPT, so you can switch it off and ask for a rewrite at any time. That's useful, but it means the discipline is up to you.

Best for: Self-taught writers who want a patient tutor for their own drafts at no cost.

5. Gemini Guided Learning - Best for learning with quizzes

Google's Guided Learning mode in Gemini, launched in August 2025, works like ChatGPT's Study mode but leans harder on visuals and quizzes.

What works: It asks probing, open-ended questions, adjusts its explanations to you, and pulls in images, diagrams, videos and quizzes to test what you've learned. Google's launch example has it walking a student through the first draft of a paper. It's free, and US college students can claim a free year of Google AI Pro until December 31, 2026.

What doesn't: Like Study mode, it's a mode you can leave at any moment. It's strongest on concepts such as thesis statements or paragraph structure, and weaker on line-by-line feedback for your prose.

Best for: Learners who want to understand how writing works through explanations, examples and quizzes.

6. Hemingway Editor - Best for learning to write clearly

Hemingway Editor grades the readability of your writing and highlights what makes it hard to read, which trains you to spot those problems yourself.

What works: The free web editor flags hard-to-read sentences, passive voice, adverbs and other weakeners, and words with simpler alternatives. You'll also get a grade level for your text. Seeing the same highlights again and again is what teaches you to write shorter, plainer sentences. Hemingway Editor Plus, from $10 a month or $100 a year, adds AI feedback on structure, logic, flow, clarity and tone and lets you change the target reading level.

What doesn't: Plus leans on one-click AI fixes, which won't teach you anything if you accept them unread. Hemingway itself says its highlights and scores are only a guide, and following them blindly can flatten your style.

Best for: Anyone who wants to learn to write more clearly and concisely.

7. LanguageTool - Best for non-native English writers

LanguageTool is a grammar and style checker for more than 30 languages that explains the rule behind each correction.

What works: Each suggestion card explains the grammar rule, so you'll see why a sentence is wrong. If you set your native language to French or German, it can also warn you about false friends, words that look alike in two languages but mean different things. It works in browsers and word processors.

What doesn't: The free version covers spelling and basic grammar and punctuation on up to 2,000 characters, and Premium adds style checks and a 150,000-character limit. Premium normally costs $24.90 a month or $69.90 a year, and it was half price when we checked.

Best for: Writers working in English as a second language, or in several languages.

Frequently asked questions

Can AI actually make you a better writer?

Yes, if you pick tools that explain, question or track your writing. A rewrite fixes one piece of writing. An explanation of the rule, or a question about what you meant, builds a skill you'll keep. For tools that help you draft and edit faster, see our ranking of the best AI writing assistants.

What is the best free AI tool for improving writing?

ChatGPT Study mode and Gemini Guided Learning are both free tutors, and they'll work on your own drafts. Hemingway's free web editor is the best free way to learn to write clearly, and Khanmigo's Writing Coach is free for US teachers and students.

What is the best AI writing tool for students?

Khanmigo's Writing Coach, because it guides students through the whole writing process without writing for them. Grammarly's AI Grader is useful too, since it gives feedback against your rubric before you submit.

Is Grammarly good for learning grammar?

It can be. Grammarly explains its suggestions, and paid plans include a progress dashboard that tracks your writing and recommends what to study. The risk is accepting fixes without reading the explanations.
