Grammarly
AI writing assistant that checks grammar, style, tone, and clarity across every app you write in.
Overview
Grammarly is one of the most widely used AI writing tools in the world, with over 40 million daily active users. Founded in 2009, it predates the modern LLM era and has been enhancing its core grammar and spell-checking technology with increasingly sophisticated AI capabilities over the years. The product works as a browser extension, desktop app, and keyboard integration that operates across Gmail, Google Docs, Microsoft Word, Slack, and virtually any text input on a computer.
Grammarly's parent company rebranded to "Superhuman" (October 29, 2025), uniting Grammarly, Coda, and Superhuman Mail under one brand — the Grammarly product itself is unchanged in name and features. Superhuman Go, a newer proactive, cross-app AI assistant (distinct from the prompt-driven GrammarlyGO), is bundled free into Grammarly Pro for individuals; Business tier access costs $33/month for team-wide use.
Grammarly's AI checks go far beyond grammar: it evaluates tone (is your email coming across as aggressive or friendly?), clarity (are your sentences too long or complex?), engagement (is your writing boring?), and delivery (is your word choice appropriate for the audience?). For business teams, Grammarly Business provides a style guide feature where companies can define approved terminology, brand voice, and writing rules that are enforced across the entire organisation. In Singapore and across ASEAN, Grammarly is widely used for business English correspondence — a critical skill in multilingual professional environments.

Use cases
What you can produce with Grammarly
- A polished professional email or cover letter with corrected grammar, improved tone, and consistent style — ready to send without a human proofreader
- A cleaned-up business report or academic paper with punctuation, subject-verb agreement, and readability issues resolved across the full document
- A plagiarism-checked essay or article scanned against billions of web pages, with a similarity report and source citations flagged
- A tone-adjusted piece of content — switching the same text from formal to conversational (or vice versa) for different audiences, e.g. a LinkedIn post vs. an internal Slack message
- A real-time proofread social media caption, product description, or short marketing copy corrected as you type across Gmail, Google Docs, or a browser text field
- An AI-detection report on a piece of content identifying likely AI-generated passages (with caveats on accuracy for academic phrasing)
- A writing style consistency audit for a team or brand — using Grammarly Business's style guide feature to enforce standardised vocabulary, banned words, and tone across multiple authors
ASEAN Perspective
Grammarly in Southeast Asia
ASEAN-region availability and pricing notes coming soon. Drop the editorial team a note via /contact/ if you can supply local context (Singapore/Malaysia/Indonesia/Thailand/Vietnam).
Grammarly is still the most established writing assistant: reliable mechanics checking, tone and clarity suggestions, and generative rewriting embedded nearly everywhere you type. The core product survived the October 2025 parent-company rebrand to Superhuman unchanged, with Superhuman Go's cross-app assistance now bundled into the $12/month Pro tier (annual). Strengths remain ubiquity and a low learning curve; it handles regional English well and ASEAN access is unrestricted. The caveats have sharpened: generative features overlap with any chatbot, non-English support is thin, billing practices (auto-renewal, strict no-refund policy) generate the loudest complaints on record, and a March 2026 class-action over the "Expert Review" feature simulating real authors' feedback raises trust questions. A dependable choice for polishing English — just calendar the renewal date.
What people say
G2 gives Grammarly 4.7/5 across 12,969 reviews and top ranking in the Winter 2026 Grid Report; the Better Business Bureau gives the company 1.04/5 from 49 reviews. Both are accurate — they're rating different things. Daily users genuinely like the product: real-time correction, browser and Google Docs integration, and real help for non-native English speakers, which is why it stays a fixture in ASEAN business correspondence. The one-star pile is almost entirely billing: surprise $144 annual auto-renewals, a strict no-refund policy, and cancellation friction. PissedConsumer shows 1.7/5 across 268 reviews with an 11% recommendation rate, again dominated by billing.
Ratings also diverge sharply by OS. iOS users rate it around 4.6/5 (181K+ ratings) while Google Play sits near 2.9/5 across roughly 240K reviews, with Android complaints centring on a content-obscuring floating widget and glitches that require reinstalling. Product-side gripes: AI rewrites can read generic, aggressive edits sometimes change meaning, and the constant premium upsells grate.
Two 2026 developments to watch. Pricing survived the October 2025 Superhuman rebrand — Pro held at $12/month annual ($30 month-to-month), and the $33/member Business tier only makes sense if you want the Coda and Superhuman Mail bundle too. And in March 2026, journalist Julia Angwin filed a class-action after Grammarly's "Expert Review" feature simulated personalised feedback from real named authors — including her — without permission. The grammar checking is as dependable as ever; the company around it keeps generating asterisks.
