Grammarly alternatives

12 tools that do a similar job, and what makes each one different.

What Grammarly is

Grammarly is a writing assistant that checks and rewrites text inside whatever you are already typing in. It ships browser extensions for Chrome, Safari, Firefox and Edge, desktop apps for Windows and Mac, integrations for Microsoft Office and Google Docs, and mobile apps for iPhone, iPad and Android. Authorship is the most unusual piece. It colour-codes sentences by their source, separating text that was typed, pasted from a website, taken from a Grammarly suggestion, or pasted from a non-web source, and it can replay how a document was written. It is opt-in, activated by a fingerprint icon, available without paying, and works in Google Docs, Microsoft Word, the Grammarly Editor, Superhuman Go and Canvas. The checking tools reach past grammar. The plagiarism checker compares text against more than 16 billion web pages plus academic papers held in ProQuest databases, drawing on sources including Wikipedia, Frontiers, PLOS One, ScienceDirect, SAGE Journals, PubMed, Elsevier, DOAJ, arXiv and Springer. It returns an originality score, highlights passages that need a citation and surfaces the matched source. A separate AI detector flags text produced by ChatGPT, Gemini, Claude and Microsoft Copilot. Grammarly puts its detection accuracy at 99 percent, while stating that no AI detector is 100 percent accurate and that human-written text can be flagged as a false positive. Named agents cover AI Grader, Citation Finder, Reader Reactions and Resume Builder. Plans separate mainly by AI prompt allowance. The Free plan carries no charge and includes 100 AI prompts a month. Plus adds full-sentence rewriting, tone adjustment, and detection of plagiarism and AI-generated text, and raises the allowance to 2,000 prompts per member per month, with one style guide, one brand tone and two user groups. Enterprise is quoted by the sales team, makes prompts unlimited per member, and removes the caps on style guides, brand tones and user groups. For organisations, the business feature set adds a style guide, brand tones, Knowledge Share, analytics, admin controls, SAML single sign-on, SCIM provisioning and centralised billing, with Enterprise layering on bring-your-own-key encryption, data loss prevention and an audit logs API. Training on customer data is switched off by default for business customers. The education product integrates with the Canvas, Blackboard and Moodle learning management systems, supports English, Spanish, French, German, Portuguese and Italian, and offers inline translation across 19 languages.

Copy.ai

Go-to-market copy and the workflows around producing it at scale: sales sequences, campaign content and research runs across a whole account list rather than one asset at a time. Positioned for revenue teams rather than individual writers, which shows in the workflow tooling more than the generation itself.

Freemium

Writer

Enterprise writing where a style guide is enforced rather than suggested. Terminology, tone and compliance rules are applied consistently across everyone who writes, and the platform can be grounded in a company's own knowledge. Bought by large organisations for governance and consistency; overkill for a small team and precisely the point for a regulated one.

Paid

Hemingway Editor

Highlights the sentence you should have cut in half. It marks dense sentences, adverbs, passive voice and complicated phrasing, and grades readability, no suggestions, no rewriting, just where the problems are. Deliberately tiny in scope and unusually good at making writing plainer. There is a free web version and a paid desktop app.

Freemium

Jasper

Marketing copy at volume, kept inside one brand's voice. Brand Voice learns from existing material, campaign tools generate a full set of assets from a brief, and templates cover the usual formats. Built for marketing teams producing a lot of copy under a consistent identity, which is a narrower job than a general assistant.

Paid

Mixpanel

Event analytics for questions that begin with 'how many users who'. Funnels, retention curves, cohorts and flows are the core, built on events with properties rather than pageviews. Strong at behavioural questions and weaker at the simple traffic reporting a marketing team wants, which is why it often sits beside a web analytics tool.

Freemium

Amplitude

Behavioural analytics built around cohorts, retention and the paths users take through a product. Comparable to Mixpanel and generally chosen for the depth of its retention and journey analysis. Experimentation and customer data tooling sit alongside. Aimed at product teams with enough volume for the analysis to mean something.

Freemium

Semrush

A broad suite covering keyword research, rank tracking, competitor analysis, site audits, backlinks, advertising research and social. The breadth is the selling point and the drawback: teams that use most of it get real value, and teams that want one job done well often find something narrower cheaper. Its competitor teardowns are the feature people cite most.

Freemium

HubSpot

Marketing, sales and support working from one contact record, which is the whole argument for it: no syncing between three systems that disagree. Email, landing pages, forms, pipelines, ticketing and reporting are included. The free CRM is real and widely used; costs climb steeply as contact counts and add-ons grow, and that is the thing to model before committing.

Freemium

LottieFiles

The ecosystem around Lottie, the format that ships vector animation as JSON. Animations stay sharp at any size, weigh a fraction of a GIF or video, and can be recoloured or controlled at runtime. The platform hosts a large library, converts from After Effects, and provides players for web and mobile.

Freemium

Warp

A terminal that treats each command and its output as a block you can navigate, copy and share, rather than an endless scroll. Input behaves like a text editor, history is searchable, and an assistant can read a failing command and suggest the fix. Workflows save parameterised commands for a team. Some of it requires an account, which is the objection people raise most.

Freemium

Glide

Generates mobile and web apps from a table your team already maintains. Rows become screens, columns become fields, and the result is installable and works offline. Best for internal tools (inventory, inspections, field data, directories), where the alternative is a spreadsheet somebody edits on a phone.

Freemium

Open-Launch

Daily product launches with a badge and a backlink, run transparently, the ranking rules and the code are public, which is unusual in this category. Free and premium submission paths, with the paid one skipping the queue. Positioned as an open alternative to the closed boards, and worth watching for that reason as much as the traffic.
