Grammarly

AI-powered writing assistant that helps improve grammar, spelling, clarity, tone, and style.

Tool characteristics

Grammarly is particularly beneficial for language learners who aim to improve their writing skills in a timely and professional manner. The platform offers a comprehensive suite of features that support users in refining their original texts, developing ideas, and enhancing overall clarity and coherence. For foreign language learners, Grammarly serves as a valuable tool for rewriting, proofreading, and improving written contributions. Its premium versions incorporate generative AI capabilities, such as automated outline creation, which assist users in planning and organizing their writing tasks. Additional features—including plagiarism detection and automated proofreading—make Grammarly a versatile resource for both independent study and classroom use, complementing written assignments and supporting ongoing language development. While Grammarly offers basic functionalities in its free, unauthenticated version, access to its full range of premium features requires users to create an account and log in.

Grammarly focuses mainly on writing and supports users in improving accuracy, coherence and style. It helps learners refine their written production by providing automatic feedback on grammar, syntax, punctuation and mechanics. For example, it can identify issues related to verb agreement, tense consistency, comma use, apostrophes, capitalisation and sentence structure.

The tool also supports lexical choice by suggesting synonyms and alternative phrasing, helping users make their vocabulary more precise and varied. In addition, Grammarly analyses style and tone, offering suggestions to adapt the text to different contexts, such as academic, business or informal communication. It can also improve clarity and conciseness by proposing sentence rewrites that reduce repetition and make the text more fluent.

Grammarly can therefore be useful as a support tool for reviewing written materials, preparing clear teaching content and showing students examples of more accurate and effective writing. It can also help teachers guide learners in developing stronger academic and professional communication skills.

Grammarly is based on Natural Language Processing, machine learning and deep learning models. Its technology analyses syntax, meaning and discourse-level patterns in order to detect writing errors and provide relevant corrections. By processing large amounts of text, the system is able to improve its understanding of user intent, context and writing style.

From a technological perspective, Grammarly uses NLP-based parsing and part-of-speech tagging to identify contextual errors in grammar and sentence structure. It also relies on advanced language models to evaluate the coherence, fluency and clarity of entire sentences, rather than focusing only on individual words. In addition, its tone detection models analyse lexical choices and sentence rhythm to infer emotion, formality and communicative intent. Grammarly also includes a plagiarism detection function, which compares texts with online sources and academic databases to identify possible similarities.

Grammarly supports mainly English, and it allows users to choose between major dialects: American, British, Canadian, Indian and Australian English. The system automatically adjusts spelling, grammar, and punctuation conventions according to the selected variety.

Grammarly also supports suggestions in six other languages: Spanish, French, Italian, German, Portuguese and Ukrainian. Grammarly also supports paragraph-level rewrites in these six languages..

Grammarly works in real time, providing instant feedback while users write across different integrated platforms. It highlights possible errors, offers short explanations and suggests alternative phrasing to improve grammar, spelling, clarity and style. Through its browser extensions and desktop apps, Grammarly can be used in tools such as Google Docs, Microsoft Word, Outlook, Gmail and other online writing environments.

Its real-time functions include grammar and spelling correction, immediate feedback, tone detection and clarity suggestions, especially in Premium versions. The tool can also adapt its suggestions according to the type of document, for example a formal letter, an academic text or an informal email. When connected online, Grammarly may also provide plagiarism checks and more advanced AI-powered feedback. Offline use is limited, as most of its AI-based features require an internet connection.

Grammarly offers several customization options for individual users. When setting up an account, learners can define their writing goals, such as intent, audience, formality, domain and tone. These settings help the AI adapt its feedback to the specific writing context, for example academic, business or casual communication.

Users can also create a personal dictionary, so that Grammarly recognises specific names, technical terms or repeated words that should not be corrected. In the Premium version, customization is more advanced, with additional support for tone and intent detection, audience adaptation and more detailed writing suggestions. Grammarly also provides writing statistics and performance summaries, which can help users monitor their progress and reflect on their improvement over time.

Grammarly does not provide formal assessment tools such as tests, grades or structured language-level evaluation. However, it can support formative assessment by offering real-time feedback on grammar, spelling, punctuation, clarity, tone and style. This feedback helps learners identify mistakes, revise their writing and improve the quality of their written production.

The platform also provides writing scores, performance insights and suggestions for improvement, which can help users reflect on their progress over time. In this sense, Grammarly can be used as a support tool for self-assessment and continuous improvement, especially in writing activities, but it does not replace teacher evaluation or formal language assessment.

Grammarly is highly accessible and flexible because it can be used across different devices and platforms, including the web editor, desktop apps for Windows and macOS, mobile keyboards for iOS and Android, and browser extensions for most major browsers. Users can also synchronise their accounts across devices, allowing them to continue their writing and revision activities in different contexts.

The platform offers flexible subscription options, usually through monthly or annual plans, making it adaptable to different user needs. In terms of accessibility, Grammarly is designed to support a wide range of users, including people who use assistive technologies. Grammarly.com and its browser extensions are compatible with tools such as Firefox with NVDA, Chrome with JAWS, and Safari with VoiceOver. Grammarly for Windows and macOS is also designed to work with NVDA and JAWS on Windows and VoiceOver on macOS.

Grammarly provides privacy and security measures to protect users’ personal data and written content. It states that it does not sell or rent personal data and does not use user content for advertising purposes. User text is processed through secure, encrypted connections to generate writing suggestions, while documents stored in the Grammarly Editor remain available until deleted by the user.

Grammarly also allows users to control and delete their data through account settings. The company may use aggregated and de-identified data to improve its services, unless users opt out. Access to user data is limited, controlled, and audited. For educational institutions, Grammarly offers specific protections aligned with regulations such as GDPR, CCPA, and FERPA, helping to safeguard student privacy.

Features

Grammarly fosters skills related to written accuracy, such as grammar, punctuation, and spelling, with the free version offering basic corrections and the premium version providing advanced suggestions for clarity, vocabulary, and tone. These features support learners in producing more fine-grained texts and noticing recurring errors. However, Grammarly does not actively develop other language skills like speaking or listening, nor does it foster deep grammatical understanding or creative language use, as it focuses on correction rather than explanation or exploration. It is most effective when paired with instruction that encourages reflection and active learning.

Grammarly supports teachers in enhancing their own writing and in guiding students toward clearer more accurate texts. The free version helps with surface-level corrections, while the premium version offers deeper stylistic and structural feedback, which can be used to model good writing and identify learner patterns. However, Grammarly does not replace pedagogical strategies for teaching language awareness, critical thinking, or genre-specific writing skills, as it lacks contextual sensitivity and instructional scaffolding. Teachers should use it as a supplementary tool rather than a primary teaching method.

Grammarly is not specifically developed for translators and interpreters as a professional category, but it can support their skills development in written English. It helps improve grammar accuracy, spelling, clarity, tone, vocabulary choice, and style, which are useful for proofreading, revising translations, preparing glossaries, reports, and professional communication. However, it does not provide specialised translation or interpreting training.

Grammarly primarily supports cognitive engagement by prompting learners to notice and correct errors, especially in grammar and style. The premium version enhances this with deeper feedback and suggestions that can encourage reflection and revision. However, it does not inherently promote deep learning, as it lacks detailed explanatory feedback and does not require learners to actively apply rules or make choices beyond accepting suggestions. Affective engagement may be supported through increased confidence in writing, while behavioral engagement is limited to passive interaction unless learners are guided to use the tool critically and reflectively.

Grammarly can foster active learning when used strategically—for example, by encouraging students to analyze feedback, compare drafts, or discuss corrections. It supports cognitive engagement by helping teachers identify patterns in student writing and tailor instruction accordingly. However, without pedagogical framing, Grammarly risks becoming a passive correction tool rather than a catalyst for behavioral engagement, such as peer review, revision cycles, or metalinguistic discussion.

Grammarly is not specifically designed to engage translators and interpreters as a target professional category. However, it can support engagement by providing instant feedback, personalised suggestions, and practical writing improvements during revision and proofreading tasks. For translators and interpreters, this may encourage autonomous learning, self-correction, and continuous improvement in professional written communication.

Grammarly is highly user-friendly, especially for beginners and non-technical users. Its clean interface, browser extensions, and mobile apps make it accessible across platforms, and the free version requires no setup beyond account creation. Learners receive instant feedback with intuitive explanations and suggestions, which can be accepted or ignored with a click. The premium version adds more advanced features, but these are integrated seamlessly, maintaining ease of use. While it is ideal for independent learners, those unfamiliar with digital tools may need initial guidance to use it effectively and critically.

Grammarly is easy to implement in educational settings, particularly as a supplementary tool for writing support. Teachers can use it to model writing, support revision, and identify common learner errors. The premium version offers analytics and plagiarism detection, which can be useful for curriculum design and assessment. However, institutional adoption may require consideration of licensing costs and data privacy policies, especially in formal education contexts.

Grammarly is not specifically designed for translators and interpreters. However, it is easy to use thanks to automatic suggestions, a clear interface, and real-time feedback on grammar, spelling, tone, and style.

Grammarly generally provides accurate corrections for common grammar, spelling, and punctuation errors, making it a reliable tool for improving written accuracy. The premium version enhances this with more nuanced suggestions for clarity, tone, and vocabulary. However, while most corrections are appropriate, learners should be aware that Grammarly may occasionally misinterpret context or offer stylistic changes that are not strictly necessary, and it does not explain rules in depth. Hence, careful revision is mandatory.

Grammarly’s suggestions are often pedagogically sound for general writing improvement, especially in terms of grammar and clarity. The premium version adds value with tone adjustments and genre-specific recommendations, which can support writing instruction. However, teachers should critically evaluate its feedback, as it may not align with specific learning objectives, academic conventions, or the developmental level of learners. For example, it may prioritize fluency over complexity. Used thoughtfully, it can complement instruction, but it should not replace teacher-led feedback or contextualized writing guidance.

Grammarly was not specifically developed for translators and interpreters. It is generally reliable for grammar, spelling, clarity, and style checks, but its accuracy may be limited with specialised terminology, translation choices, and context. Human professional judgement remains essential.

Grammarly’s AI outputs are generally opaque, especially in the free version, where suggestions are presented without detailed explanations of the underlying rules or reasoning. While learners can see what is being corrected, they are not always shown why a particular suggestion is made. However, Grammarly has recently introduced Grammarly Authorship, a feature that increases transparency by identifying which parts of a document are human-written, AI-generated, or AI-edited. This helps learners reflect on their writing process and understand their interaction with AI tools, though it does not yet offer full explainability of AI decisions.

Grammarly provides limited insight into how its AI decisions are made. Teachers cannot directly access the logic behind specific suggestions, making it difficult to evaluate whether feedback aligns with instructional goals, and requiring teachers to critically assess AI outputs within their teaching context. Recent functionalities like Grammarly Authorship help in this respect.

Grammarly was not specifically developed for translators and interpreters. Its AI suggestions are usually explained through short comments or correction prompts, helping users understand grammar, clarity, tone, and style improvements. However, the tool does not fully explain how its AI makes decisions, so professional judgement remains necessary.

Grammarly promotes procedural autonomy by allowing learners to write, revise, and receive feedback independently, with minimal technical barriers. Its real-time suggestions and customizable goals (in the premium version) support self-directed practice, enabling learners to adjust tone, intent, and audience. However, content autonomy is limited, as learners cannot influence the feedback logic or explore alternative linguistic choices beyond what the AI suggests. While Grammarly encourages revision, it does not guide learners in setting learning objectives or reflecting on their progress, so its contribution to self-regulated learning depends on how learners engage with it critically and reflectively.

Grammarly offers teachers a flexible professional tool for enhancing writing and supporting student development. It can be used to model revision strategies, analyze learner errors, and scaffold writing tasks. However, teachers do not have control over the feedback algorithms or the pedagogical framing of suggestions, which limits their ability to play a teacher role. While the premium version provides analytics and genre-specific feedback, it does not allow for a customization aligned with curriculum goals or learner profiles. Thus, Grammarly supports professional autonomy in terms of use and integration, but not in terms of instructional design or feedback personalization.

Grammarly was not specifically developed for translators and interpreters. However, it supports autonomy by allowing users to revise texts independently, receive instant feedback, and improve grammar, clarity, tone, and style at their own pace. For translators and interpreters, it can support self-correction and autonomous proofreading, but it does not replace expert linguistic judgement
