Linguix: Free AI Grammar Checker and Writing Assistant for Professionals (2026)
Linguix is an AI-powered grammar checker and writing assistant that works across the web in real-time, catching grammar errors, punctuation mistakes, and style issues as you type on any website. Its browser extension deploys across Gmail, social media, CMS platforms, and web text fields — making professional-quality writing accessible wherever you work online.
Linguix positions itself as a free-first grammar checking tool for professionals and non-native English speakers who need reliable real-time correction without paying Grammarly's subscription price.

What Linguix Does Well
Free Real-Time Grammar Checking Everywhere
Linguix's core value is delivering reliable grammar and style correction across any website at no cost. Unlike Grammarly's free tier which limits certain features, Linguix's free grammar checking is comprehensive — catching spelling errors, punctuation mistakes, subject-verb agreement problems, and basic style issues in real-time.
Business Writing Templates (Pro)
The Pro plan includes a library of business writing templates and personal snippets — pre-written blocks of text that can be inserted with keyboard shortcuts. For professionals who write repetitive email types or use standard phrasing frequently, this saves significant time compared to retyping standard responses.
Team Writing Quality Management
Linguix Pro includes team management features: shared style guides, team snippet libraries, and writing analytics. Organizations can enforce consistent phrasing, terminology, and quality standards across all team members' written communication — at a price point typically lower than enterprise grammar tools.
Vocabulary Enhancement Suggestions
Beyond error correction, Linguix suggests vocabulary improvements — helping writers expand their word choice beyond repetitive defaults. This is particularly valuable for non-native English speakers who tend to rely on a smaller set of familiar words.
Known Limitations
- No AI text generation: Linguix does not generate new content from prompts. It only corrects and improves text that already exists — writers needing AI-assisted drafting must use a different tool.
- English-focused: Linguix supports US and UK English prominently. Non-English language support is not clearly documented, limiting its usefulness for multilingual writers.
- Less brand recognition than Grammarly: Linguix has a smaller user base and community than Grammarly, meaning fewer third-party reviews, tutorials, and integration resources are available.
- No plagiarism detection: Unlike Grammarly Pro, Linguix does not include plagiarism checking — a meaningful gap for academic or content writers concerned about originality.
- Pro plan pricing perception: At $30/month monthly, Linguix Pro is not dramatically cheaper than Grammarly Pro, making the annual plan ($10/month) the only clearly cost-advantaged option.
Best For: Who Should Use Linguix
- Non-native English speakers who need free, reliable grammar correction across email, social media, and web apps
- Professionals who write frequently in multiple platforms and want a lightweight alternative to Grammarly
- Small business teams that want shared snippet libraries and consistent communication standards at an affordable price
- Writers who primarily need grammar correction rather than full AI writing assistance
Who Should Look Elsewhere
- Writers needing AI text generation — Grammarly Pro, Jasper, or Copy.ai include generation alongside editing
- Long-form writers who need document-level structural analysis — ProWritingAid offers 25+ specialized reports
- Writers working in non-English languages — LanguageTool supports 30+ languages and is the better option
Pricing & Cost at Scale
Plan Overview
- Free: Real-time grammar checking, unlimited usage, basic style suggestions — no credit card required
- Pro: $30/month (monthly), ~$20/month (quarterly), or $10/month (billed annually at $120/year) — advanced style suggestions, business writing templates, personal snippets, vocabulary enhancements, team features
Cost at Scale
For individual writers: the free plan covers core needs. Pro at $120/year ($10/month annually) is competitive with alternatives. A 10-person team on Pro saves meaningful time through shared templates and consistent quality enforcement — estimated to offset cost within weeks for teams doing daily client communication.

FAQ
Is Linguix free?
Yes. Linguix has a genuinely free plan that provides real-time grammar checking across any website with no word count limit. The Pro plan ($10/month annual, $30/month monthly) adds advanced style suggestions, templates, and team features.
What types of content can Linguix check?
Linguix checks any written English text — emails, social media posts, documents, web forms, CMS content, and more. It works on any website via the browser extension and is not limited to specific content types.
How does Linguix compare to Grammarly?
Linguix's free tier offers comparable basic grammar checking to Grammarly's free tier. Grammarly's paid plans are more feature-rich (plagiarism detection, full-sentence AI rewrites, AI text generation, tone detection). Linguix Pro is simpler and potentially more affordable annually. For core grammar correction needs, both tools perform reliably — choose based on whether you need Grammarly's additional AI features.
Does Linguix support languages other than English?
Linguix is primarily designed for English (US and UK). Non-English language support is not prominently documented. For multilingual grammar checking, LanguageTool with 30+ language support is a better alternative.
Can Linguix write content for me?
No. Linguix is a grammar checker and style corrector, not an AI content generator. It improves text you've already written but does not create new content from prompts. For AI content generation, you'd need a tool like Jasper, Copy.ai, or Rytr.
