Operating as a persistent overlay across over 500,000 web applications, desktop programs (Windows and macOS), Microsoft Office, Google Docs, and iOS/Android keyboards, Grammarly analyzes text in real time to eliminate grammatical errors, streamline wordy phrasing, and calibrate tone to match the writer's intent. Following its corporate evolution under the Superhuman Platform umbrella alongside Superhuman Mail and Coda, Grammarly has expanded from a personal proofreader into an enterprise-grade proactive AI communication suite. In 2026, Grammarly goes well beyond red-underline spellchecking with a suite of specialized AI Agents and document integrity tools. Writers can invoke purpose-built agents—including AI Grader, Citation Finder, Reader Reactions, and Paraphraser—alongside generative AI drafting directly inline where they work. To address academic and professional transparency in the generative AI era, Grammarly offers built-in Plagiarism Detection, an AI Detector, and Grammarly Authorship, which tracks how a document was constructed by automatically categorizing text as human-typed, pasted from external sources, or generated/modified with AI. For teams, Grammarly enforces organizational consistency through custom Style Guides, Brand Tones, reusable Snippets, and Knowledge Share. Grammarly simplified its subscription structure by consolidating its legacy individual 'Premium' and team 'Business' offerings into a single unified tier: Grammarly Pro. The Free plan ($0/month) covers essential spelling, punctuation, basic tone visibility, and 100 generative AI prompts per month. Grammarly Pro is priced at $12/member/month when billed annually ($144/year) or $30/member/month when billed monthly ($60 quarterly), unlocking unlimited personalized fluency suggestions, full-sentence rewrites, tone adjustment, citation formatting, plagiarism and AI detection, 1 team style guide, and 2,000 generative AI prompts per member each month.

[Profile (Markdown)](https://openaitools.app/tool/grammarly.md) ## HyperWrite - AI Assistant HyperWrite is an AI writing assistant developed by OthersideAI and distributed mainly through a Chrome extension that has around 80,000 users and a 4.1 rating from over a hundred reviews. Rather than positioning itself as a chatbot you visit, it lives inside the editors people already use. The signature capability is predictive autocomplete. As you type, HyperWrite shows subtle gray suggestions for the next words or the rest of a sentence; pressing Tab accepts them, keeping hands on the keyboard. The developer says real-time suggestions inside ChatGPT and Gemini are among its fastest-growing features, and the extension also works in Gmail, Google Docs and other web apps. HyperWrite is available as a freemium product: the extension is free to install and the store listing notes in-app purchases for paid tiers. Its combination of lightweight autocomplete and a wider set of AI writing and research tools makes it a reasonable fit for people who write emails, docs and prompts all day and want fewer interruptions. **Pricing & Plans:** Freemium: free install with in-app purchases for paid tiers. Confirm current plan prices on the developer's official site. - **Real-time inline autocomplete:** Suggests the next words and completes whole sentences in gray inline text, accepted instantly with Tab so your flow is not interrupted. - **Works across major web apps:** Offers suggestions inside ChatGPT, Gemini, Gmail, Google Docs and other web editors rather than in a separate document. - **Context-aware suggestions:** Suggestions adapt to the surrounding text, helping them feel consistent with how you personally write. - **Broader assistant features:** Beyond autocomplete, the assistant supports drafting, rewriting and research-style tasks through the same extension and web app. **Strengths:** Autocomplete feels native because suggestions appear inline in the app you are already using; Tab-to-accept keeps typing flow smooth, with no copy-paste between tools; Large installed base and a long review history give a clearer picture of reliability; Covers both quick completion and broader writing or research tasks in one extension [Profile (Markdown)](https://openaitools.app/tool/hyperwrite-ai-assistant.md) ## Frequently Asked Questions ### How do Grammarly and HyperWrite - AI Assistant compare in monthly traffic?
