Zuni
Inline AI writing assistant that rewrites text right where you type in Chrome.
Zuni is a focused, privacy-minded Chrome extension that delivers inline text rewriting, grammar correction, tone adjustment, and translation without tab-switching. The free tier (50 requests/month) is a generous trial, and Pro at $9.99/month is one of the cheapest ways to get unlimited inline rewriting. It competes well with Grammarly for inline editing but lacks deep integrations and cross-platform support. If your work lives in Gmail, Google Docs, or other web text fields, Zuni is a solid, budget-friendly choice. If you need a general AI assistant or API access, look elsewhere.

About Zuni
Zuni is a Chrome extension that brings AI-powered writing assistance directly into any webpage, letting you rewrite, rephrase, correct grammar, adjust tone, or translate text inline without leaving the page. Built for professionals, writers, students, and social media managers who compose content in web-based tools like Gmail, Google Docs, Notion, and social platforms, it activates via a keyboard shortcut or context menu, dropping a subtle overlay with suggestions right at your cursor. Unlike sidebar AI assistants, Zuni keeps you in the text field you're editing, minimizing workflow disruption and helping you maintain focus. It uses large language models to generate context-aware, human-like responses and claims to process data securely without storing your content. The extension supports customizable tone presets, text summarization, expand or shorten selected text, and AI-powered autocomplete-like suggestions. Zuni is available as a freemium Chrome extension. The free tier gives you a taste of its capabilities, while the Pro plan unlocks unlimited usage and premium features like advanced tone adjustments and longer content generation. At $9.99 per month, it's positioned as an affordable, focused alternative to general-purpose AI chatbots or sidebar tools. Whether you're polishing an email, refining a blog post, or drafting social media updates, Zuni aims to be the lightweight, privacy-conscious layer that sits between your keyboard and the web.
Behind the Verdict
Zuni is a deliberate lightweight tool designed for one thing: polishing text where you already type. It's not a chatbot; it's an inline helper. The activation via keyboard shortcut or context menu keeps you in the flow, and the overlay suggestions at your cursor are a smart design that reduces context switching. Privacy is a core selling point—Zuni claims not to store your content, which matters for professionals handling sensitive emails or documents. Strengths: The free tier is practical for light users, and the Pro price is aggressive compared to rivals like Grammarly Premium ($12/month) or ProWritingAid. The tool covers the most common writing needs: rewriting, grammar, tone, translation, summarization, expand/shorten. It works on any webpage with text fields, making it versatile within Chrome. Weaknesses: It's Chrome-only, so Firefox or Safari users are out. No API, no offline mode, no mobile apps. The free tier's 50 requests per month can vanish quickly during a heavy writing day. The feature set is narrower than full writing suites—no plagiarism checking, no style guides, no team features. For power users, the lack of custom shortcuts or integrations beyond the browser could feel limiting. Where it fits: Solo professionals, students, and content creators who want quick, inline assistance without switching tabs. It's also great for non-native speakers who need instant grammar and tone fixes. Where it doesn't fit: Teams needing centralized billing, enterprise security features, or deep workflow automation. Compared to alternatives, Zuni is the minimalist's choice. Grammarly offers more integrations and a bigger feature set, but Zuni's price and privacy focus are strong counterpoints. If you only need inline rewriting and value a clean, fast experience, Zuni is worth the bargain.
