    Best AI Tools for ESL Students

    If English isn't your first language, college adds an extra layer of work: dense readings, fast lectures, and essays graded on clarity as well as ideas. AI tools can help you check grammar, hear pronunciation, follow lectures and understand difficult passages — but they work best as support for your own learning, not a replacement for it. Here are the most useful AI tools for ESL, multilingual and international students, with honest downsides and current pricing.

    Check your course policy first. Many instructors treat AI-rewritten, translated or AI-generated text in graded work as not your own work. Using tools to understand readings, check your own sentences and practice English is usually fine, but submitting text a translator or AI wrote can break your course's academic integrity rules. Check your syllabus, ask your instructor when unsure, and consider your campus writing center — many have tutors who work with multilingual writers.

    Grammarly

    Best for: checking and learning from your own English writing

    Grammarly checks spelling, grammar, clarity and tone as you write in Google Docs, Microsoft Word, your browser and its apps, and it explains why each suggestion is made — useful when you're learning English grammar rules. The free plan covers core grammar and spelling corrections, tone detection and 100 AI prompts a month. Grammarly Pro adds full-sentence rewrites, fluency suggestions that flag phrasing that sounds unnatural, a plagiarism checker, AI-text detection and 2,000 AI prompts a month, for $12/month billed annually or $30/month billed monthly. Grammarly works in English only.

    Why students use it:

    • Explains why each correction is suggested, so you learn as you edit
    • Works in Google Docs, Word and your browser
    • Free plan covers core grammar and spelling
    • Pro flags unnatural-sounding phrasing
    Downside: There's a limited-time 50% student discount on Pro (and some colleges provide access through a campus license, so check first), monthly billing for Pro is expensive, and accepting every rewrite can replace your own voice.

    Grammarly is our top pick because it explains its suggestions on writing you did yourself, which helps you learn. Use it as a learning aid, review every suggestion, and follow your instructor's AI policy.

    QuillBot

    Best for: summarizing readings and finding clearer wording for your own sentences

    QuillBot is an AI writing toolkit with a Paraphraser, Grammar Checker, Summarizer, Translator, Citation Generator and AI Detector. The free Paraphraser handles 125 words at a time in two modes (Standard and Fluency), and the free Summarizer handles up to 1,200 words — helpful for checking you understood a long reading. Premium unlocks unlimited paraphrasing, more modes and a plagiarism checker for $19.95/month or $99.95/year ($8.33/month), and verified students can get 25% off Premium.

    Why students use it:

    • Summarizer helps you check your understanding of long readings
    • Fluency mode suggests more natural phrasing for your own sentences
    • Free citation generator
    • 25% student discount on Premium
    Downside: Running a source through a paraphraser and submitting it is still plagiarism without a citation, and many instructors treat AI-paraphrased text as misconduct. The free plan's limits are tight.
    #3

    DeepL

    Best for: checking your understanding of difficult passages in your first language

    DeepL is an AI translator known for natural-sounding translations, and DeepL Write suggests grammar and rephrasing improvements in several languages, including English. Translating a confusing paragraph into your first language can help you check whether you understood it. DeepL has a free plan with limits on text length and file translations; paid DeepL Pro plans raise those limits.

    Why students use it:

    • Natural-sounding translations for checking comprehension
    • Free plan available
    • DeepL Write can help you check grammar in English
    Downside: It translates for you rather than teaching you English, and writing an assignment in your first language then submitting a machine translation is banned in many courses. Write Pro and Translator Pro are separate paid products.
    #4

    Speechify

    Best for: hearing how English text sounds and listening to readings

    Speechify is a text-to-speech app for iOS, Android, Mac, Chrome and the web. Listening while you read can help with pronunciation and with getting through long readings. The free plan includes 10 basic voices and speeds up to 1.5x. Premium adds 1,000+ natural voices in 60+ languages, speeds up to 5x, Scan & Listen for printed pages, and AI summaries, for $29/month or $139/year (about $11.58/month). Speechify says verified students can get 25% off Premium through UNiDAYS.

    Why students use it:

    • Hear pronunciation while you follow the text
    • Scan & Listen reads printed textbook pages (Premium)
    • 25% student discount through UNiDAYS
    Downside: The free voices are basic and capped at 1.5x speed, and monthly billing is expensive compared with the annual plan.

    Otter.ai

    Best for: following fast lectures with a live transcript

    Otter.ai records audio and transcribes it live, so you can read along when a lecturer speaks quickly, then review a searchable transcript and AI summary afterward. Its mobile app can record in-person lectures, and it can join Zoom, Google Meet and Microsoft Teams calls. The free Basic plan gives 300 minutes a month but shows only the first 30 minutes of each conversation. Otter Pro costs $16.99/month or $8.33/month billed annually, with 1,200 minutes a month and 90 minutes per conversation, and students with a .edu email get 20% off Pro ($79.99/year).

    Why students use it:

    • Live transcript to read along during lectures
    • Searchable transcripts and AI summaries for review
    • 20% student discount on Pro
    Downside: The free plan's 30-minute limit is shorter than most lectures, transcripts can garble names, technical terms and accented speech, and you need permission to record — check your school's policy and ask your instructor.

    ChatGPT

    Best for: conversation practice and plain-English explanations

    ChatGPT can explain a difficult passage or idiom in simpler English, give feedback on sentences you wrote, and — with voice mode — let you practice speaking English out loud on any topic. Study mode, available on all plans, guides you with questions instead of giving answers. Plans include Free, Go ($8/month in the US) and Plus ($20/month); voice use is limited on Free and Go.

    Why students use it:

    • Speaking practice on any topic with voice mode
    • Explains idioms and difficult passages in simpler words
    • Useful free plan
    Downside: It can confidently give wrong grammar explanations or invent facts and citations, and it makes it easy to generate text you shouldn't submit as your own.

    Frequently Asked Questions

    It depends on what you need help with. Grammarly is a strong choice for checking and learning from your own writing, Otter.ai helps you follow fast lectures with a live transcript, Speechify lets you listen to readings, and ChatGPT's voice mode is useful for speaking practice. Many ESL students combine a writing checker with one listening or speaking tool.

    Using Grammarly to check grammar and spelling in writing you did yourself is usually allowed, but some instructors limit AI rewriting or generative features on graded work. Check your syllabus, and ask your instructor if you're unsure which features are allowed.

    Usually not for graded work. Many courses treat submitting machine-translated or AI-written text as an academic integrity violation, because the English isn't your own work. Using a translator to understand readings or check a word is usually fine — ask your instructor what's allowed.

    Transcription apps like Otter.ai show a live transcript you can read along with and review later, and AI summaries help you check the main points. Always ask permission before recording, follow your school's recording policy, and review transcripts carefully, since they can mishear names and technical terms.
