Grammarly Alternatives

QuillBot is an AI writing suite built around a paraphraser, a grammar checker, and a set of supporting tools for clearer writing. It is made for students, content creators, and working professionals who want to rewrite, correct, and polish text without switching between separate apps. You can paste, type, or upload your work and run it through paraphrasing, summarizing, citation, and originality checks in one place.

Key Highlights

• Paraphraser with multiple rewriting modes and synonym control
• Grammar checker that corrects errors across 6 languages
• Summarizer that condenses long text into key points
• Plagiarism checker and an AI content detector
• AI Humanizer that rewrites text to sound more natural
• Browser extensions plus macOS, Windows, Word, and mobile apps

What Makes It Different

QuillBot's core draw is its paraphrasing engine, which rewrites sentences in different tones and styles while keeping the original meaning. Rather than acting as a single grammar checker, it bundles paraphrasing, summarizing, citation, plagiarism detection, and AI detection into one workspace, so you stay in one tool instead of copying text between tabs.

Features & Capabilities

The paraphraser offers built-in modes (Standard and Fluency on the free plan, plus 9 modes and custom modes on Premium), works in 23 languages, and lets you adjust synonym frequency. The grammar checker, summarizer, and citation generator handle routine cleanup, while the plagiarism checker and AI detector help verify originality before you publish.

QuillBot runs where you already write through Chrome and Edge extensions, a macOS app, a Word add-in, and Android and iOS apps. Documents save into QuillBot Flow, and Premium adds faster processing, larger summaries, and unlimited paraphrasing and humanizing.

User Ratings and Testimonials

QuillBot holds a 4.4 out of 5 rating on G2 from roughly 113 reviews, and its Chrome extension is rated 4.5 out of 5. The company reports more than 35 million writers across 180+ countries. Users praise how quickly it rewrites text and improves clarity while keeping the meaning intact. The most common criticism is that the free version is limited: paraphrasing caps at 125 words, and several stronger features are locked behind Premium.

Pricing & Value

• Free: $0, paraphrase up to 125 words in 2 modes, basic grammar fixes, basic summaries, and limited AI Detector access
• Premium: $8.33/month billed annually (about $19.95 billed monthly), with unlimited paraphrasing, 9+ modes, advanced grammar suggestions, custom summaries, plagiarism checking, and unlimited AI Humanizer
• Team Plan: custom pricing that adds usage metrics, a user management dashboard, centralized billing, and priority support

The free tier is enough to test the paraphraser and grammar tools, while Premium unlocks unlimited rewriting and the full toolset for regular writers.

ProWritingAid helps writers edit prose and develop long-form stories. It combines grammar and style suggestions with writing reports, sentence rephrasing, and story critique tools. Writers can use the feedback to revise a draft while deciding which changes preserve their intended meaning and voice.

Key Highlights

• Grammar, spelling, and punctuation checks
• Writing reports for detailed line editing
• Rephrase for sentence alternatives
• Sparks for writing experiments
• Story Canvas and manuscript analysis tools

What Makes It Different

The product goes beyond correcting individual typos by offering reports and story feedback. Line editing and whole-manuscript analysis address different questions. A grammatical sentence may still need revision for pacing, character development, or its role in a longer piece.

Features & Capabilities

Run reports on a draft, examine the suggested changes, and accept the ones that suit the document. Rephrase can offer alternative wording, while Sparks supports developing or refining passages.

Story tools cover areas such as plot, characters, pacing, and reader response. Advanced manuscript analysis uses Story Credits. Keep the original draft and compare revisions carefully; an AI suggestion does not need to be accepted simply because it is available.

User Ratings and Testimonials

Evaluate the tool on your own genre and document length. Detailed feedback can be useful, but it also takes time to review. The best result depends on editorial judgment rather than accepting every suggestion or assuming a score proves that a story is finished.

Pricing & Value

• Free: suggestions for 500 words at a time, with daily report and AI-feature limits
• Premium: $30/month, or $120/year
• Premium Pro: $36/month, or $144/year, with higher feature allowances

Lifetime options are also available. Story Credits are purchased separately for advanced manuscript analysis; the subscription and credit allowance should be considered together.

Wordtune is an AI writing assistant for rewriting, grammar and spelling checks, and summarization. It helps people revise emails, documents, captions, and other text while keeping control over the final wording. Users can compare suggestions instead of accepting a generated draft unchanged.

Key Highlights

• Rewrites and AI suggestions for existing text
• Grammar and spelling corrections
• AI summarization
• Vocabulary, clarity, and fluency tools on eligible plans
• Browser extensions and other supported interfaces

What Makes It Different

Wordtune concentrates on improving wording rather than building a full marketing or search platform. The rewriting workflow starts with something the user wants to say, then offers alternatives. Summarization addresses a separate task: condensing material before deciding what needs a closer read.

Features & Capabilities

Write or paste text, inspect suggested rewrites, and choose wording that preserves your meaning. Grammar and spelling tools can help with individual corrections. Review technical terms, names, and important claims yourself, particularly in professional or academic material.

The free Basic plan limits daily rewrites and monthly summaries. Advanced increases those allowances, while Unlimited removes the listed rewrite and summary quotas. Extensions for Chrome and Edge let users work in supported browser contexts; availability can differ by interface.

User Ratings and Testimonials

The pricing page publishes selected testimonials about captions, writing, and customer communication. These describe individual customer experiences rather than guaranteed productivity gains. Test the suggestions on your own writing style, including passages where the exact meaning must remain unchanged.

Pricing & Value

• Basic: $0, with 10 daily rewrites or AI suggestions and 3 monthly summaries
• Advanced: higher allowances, including 30 daily rewrites and 15 monthly summaries
• Unlimited: the listed rewrite and summary features have unlimited use
• Trial: 3 days on paid plans; payment details required, then charges apply unless canceled

The Hemingway App reviews your text. It points out complex sentences, passive voice, and readability issues. This way, you can write more like the famous author himself.

This editing tool is great for writers, marketers, and anyone who wants to make clear, strong content. It helps ensure readers finish what they start.

Key Highlights

• Instant readability scoring - Get your text's grade level in seconds
• Color-coded feedback - Visual highlights show exactly what needs fixing
• Passive voice detection - Spots weak sentence structures automatically
• Adverb and complex phrase alerts - Identifies words that weaken your message
• Desktop and web versions - The Classic desktop editor supports offline editing; Plus AI features use the online service
• Export options - Save to Word, PDF, or publish directly to WordPress

What Makes It Different

Hemingway highlights readability issues; Hemingway Editor Plus also offers AI grammar correction and rewriting tools. While tools like Grammarly catch spelling errors, Hemingway targets readability and writing strength. Its color-coding system makes editing easy to see. You spot problems right away, so you don't have to read long explanations.

Features & Capabilities

The app scores your writing on a grade level scale, with a target reading level chosen for the intended audience. Yellow highlights mark long, complex sentences. Red shows very hard-to-read sentences that need breaking up. Blue identifies adverbs and weak phrases. Green catches passive voice usage.

Writers use it for blog posts, marketing copy, emails, and book editing. The desktop version works offline and includes formatting options for publishing. The web version offers quick analysis for shorter pieces.

User Ratings and Testimonials

Use the highlights as editing suggestions, then read the revision aloud. A lower reading grade is not automatically the best fit for every audience, and technical writing may need terms that the app flags as complex. Preserve the intended meaning while editing.

Pricing & Value

Free Web Version - Basic editing and readability analysis.

Classic desktop app: $19.99 one-time purchase, with offline editing and Word, PDF, HTML, and Markdown exports
