Feature comparison GrammarlyGO vs QuillBot
Paraphrasing and rewriting
QuillBot leads this area with its diverse rewriting modes and fine-grained control over the output. Users can adjust the level of rewriting, choose between fluency or creativity, and compare different versions of a sentence. GrammarlyGO includes paraphrasing, but it is goal-driven and context-aware rather than mode-specific. It is better suited to improving clarity and tone than total rewording.
Grammar checking and fluency
Both tools offer grammar correction, but GrammarlyGO provides deeper suggestions related to structure, tone, and clarity. It goes beyond fixing errors to reshape sentences for better reader impact. QuillBot’s grammar checker is effective for quick fixes, especially for non-native writers, but less advanced in style refinement.
Tone and audience adaptation
GrammarlyGO allows users to define goals and get suggestions aligned with their writing intent such as making a message more confident, formal, or friendly. This is particularly useful in business writing. QuillBot includes a tone detector, but it is less interactive in guiding the tone throughout the writing process.
Collaboration and team features
GrammarlyGO supports enterprise use, with team management, analytics, and style guide enforcement. It helps ensure that entire teams maintain consistency in brand voice. QuillBot is more individual-focused and does not currently offer enterprise-grade team features.
AI detection and content authenticity
Both tools have added AI detection capabilities in 2025. QuillBot provides an AI humanizer that helps make AI-generated content more natural and undetectable. This is useful for users concerned about originality or detection in academic and professional contexts. GrammarlyGO offers context-sensitive rewriting but does not include a humanizer feature.
Pricing comparison
- GrammarlyGO starts at around 12 USD per month for individual users, with business plans available for teams
- QuillBot Premium begins near 9 USD per month and often provides academic discounts
Both tools offer free versions, but some features like advanced rewriting and plagiarism detection require a paid plan.
Platform compatibility and integrations
GrammarlyGO works across multiple platforms including Chrome, Safari, Firefox, Edge, Windows, macOS, iOS, Android, and web apps. It is tightly integrated into Google Docs and Outlook, making it ideal for everyday business communication.
QuillBot also supports browser extensions, Word integrations, and dedicated apps. Its online editor is lightweight and fast, well-suited for students and writers working across multiple browsers or devices.
