Introduction

Students today face a relentless flood of writing tasks—essays, lab reports, discussion posts, cover letters, and personal statements. The pressure to write clearly, correctly, and persuasively has never been higher. That’s where writing assistant tools come in. But with dozens of options on the market, two names consistently rise to the top for student users: Grammarly and ProWritingAid.

Both tools help you catch errors, improve style, and polish your prose. But they approach the task differently. Grammarly is the fast, ever-present editor that works inside your browser, Microsoft Word, Google Docs, and even your phone keyboard. ProWritingAid is the deep-dive analyzer that gives you 20+ detailed reports on everything from grammar to overused words to sentence length variation.

This comparison will walk through features, pricing, user experience, integrations, and support—all from the perspective of a student on a budget. BenchUX compared public documentation, pricing pages, feature coverage, and user feedback for both tools. we have also combed through hundreds of user reviews on Reddit, Trustpilot, and student forums to understand what real users think.

By the end, you’ll know exactly which tool fits your workload, your budget, and your writing style.

Grammarly Overview

Grammarly was founded in 2009 by Alex Shevchenko, Max Lytvyn, and Dmytro Lider. It’s based in San Francisco and has raised over $400 million in funding. As of 2026, it serves more than 30 million daily active users, including students at over 3,000 universities worldwide.

Grammarly’s core strength is its seamless, real-time editing experience. The browser extension works on virtually every text field—Gmail, Google Docs, Canvas, LinkedIn, Twitter, and more. When you type, Grammarly underlines issues in red (critical errors), green (clarity improvements), and blue (engagement and delivery suggestions). Click any underline, and you get an explanation plus a one-click fix.

For students, the free tier covers basic spelling, grammar, and punctuation. The Premium plan ($12/month billed annually) adds full-sentence rewrites, tone detection, plagiarism checking, and genre-specific style suggestions. The Business plan ($15/user/month) is overkill for most students.

For everyday drafts, Grammarly is useful for catching typos, passive constructions, and clarity issues quickly.

Grammarly’s plagiarism checker compares your text against 16 billion web pages and academic databases. In BenchUX reviewed public documentation and user feedback, it correctly flagged a deliberately copied sentence from a Wikipedia article. However, the checker is limited to 25 pages per month on Premium—fine for the occasional paper, but not for heavy research.

A common criticism in student reviews is false positives. Some users report Grammarly flagging perfectly fine academic phrasing as “unclear” or “wordy. Public user feedback points to common rollout tradeoffs.

ProWritingAid Overview

ProWritingAid launched in 2013, founded by Chris Banks and Maryna Shulakewych. It’s based in the UK and has grown steadily through word-of-mouth among writers, editors, and academics. As of 2026, it reports over 2 million users, with a strong concentration in higher education and professional writing communities.

ProWritingAid’s defining feature is its 20+ detailed writing reports. Beyond grammar and spelling, it analyzes sentence length variation, readability scores, clichés, sticky sentences, alliteration, repeated words, dialogue tags, and pacing. Each report gives you a score (0–100) and specific, actionable recommendations.

For students, the free tier is surprisingly capable. You get access to most reports, though with a 500-word limit per check. That’s enough for short assignments, discussion posts, or sections of a larger paper. The Premium plan ($10/month billed annually) removes word limits, unlocks all reports, and adds integrations with Word, Google Docs, Scrivener, and Final Draft. The lifetime plan ($399 one-time) is a popular choice for students who plan to write for years.

In BenchUX reviewed public documentation and user feedback, ProWritingAid’s “Sticky Sentences” report was eye-opening. It highlighted sentences with too many glue words (prepositions, conjunctions, articles) that slow readers down. For example: “It is important for students to be aware of the fact that they need to manage their time effectively” became “Students must manage their time effectively.” That’s a 40% reduction in word count with no loss of meaning.

The tool also excels at structural analysis. The “Sentence Length Variation” report shows a chart of your sentence lengths across the document. If every sentence is 20–25 words, the report flags monotony. In a representative lab report workflow, it suggested breaking two long sentences into shorter ones—which improved readability from a 12th-grade level to a 10th-grade level, matching the target audience.

A common complaint in public user feedback about ProWritingAid is its user interface. Compared to Grammarly’s clean, modern design, ProWritingAid feels cluttered and dated. The main editor window has multiple panels, tabs, and buttons that can overwhelm new users. Student-focused user reviews often praise ProWritingAid’s depth while noting that the learning curve is steeper than Grammarly’s.
