Instead of copying text into a separate chat window, you open the side panel and work in place: highlight a passage to translate or summarize, ask a question about the page, or start drafting from a prompt. It is designed for people who live in the browser and want AI help without breaking focus. The feature set centers on everyday knowledge work. Writing tools help you draft, rewrite, and refine text; translation and summarization handle long content quickly; a prompt generator helps you get better results from other AI tools; and code analysis offers a hand when you are reading technical material. Because it runs as a browser extension, setup is a single install rather than a new application. Access model is freemium: there is a free tier with limited usage, and paid plans add more capacity and advanced features. As with any AI assistant, treat the output as a strong first draft — particularly for code and anything you plan to publish — and verify important details yourself. **Pricing & Plans:** Freemium. A free tier provides limited usage, and paid plans unlock more queries and advanced features. Check the provider's site for current quotas and prices. - **AI Writing Help:** Draft, rewrite, and polish text with an AI assistant that sits beside any page you are working on. - **Translation and Summarizing:** Translate content between languages and summarize long pages or documents in a few clicks. - **Sidebar Q&A:** Ask questions about the page you are reading and get contextual answers without leaving it. - **Prompt Generator:** Generate effective prompts and use them across other AI tools and workflows. - **Code Analysis:** Get help understanding and analyzing code snippets while you browse documentation or repositories. **Strengths:** Works as a sidebar on any web page in Chrome and Edge; Covers writing, translation, summarizing, Q&A, prompts, and code; No tab-switching distraction while you work; Free tier available to try before paying **Limitations:** Requires installing a browser extension; Free quota is limited, with heavier use behind a paid plan; Answers depend on the underlying GPT models and can need review; Tied to browser usage rather than a standalone app [Profile (Markdown)](https://openaitools.app/tool/gptplus.md) ## Grammarly Grammarly is the world's most widely deployed AI writing and communication platform, trusted by more than 40 million daily users and 50,000 organizations including Atlassian, Databricks, and Zoom. 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.
