Linguix

Linguix is an AI writing assistant for improving grammar, clarity, and communication across websites and supported apps. It checks spelling and grammar, offers writing suggestions, and can paraphrase or rewrite text. Typing shortcuts help handle repeated wording, while tone suggestions and a Content Quality Score provide additional ways to review writing. The score considers sentence length, vocabulary complexity, and passive voice. Linguix says it supports English, Spanish, Portuguese, German, French, and Polish. It is available on web, Android, and iOS, through an API, and as browser extensions for Chrome, Firefox, Edge, Safari, Opera, and Brave. Listed integrations include Gmail, Outlook, Google Docs and Sheets, Slack, Notion, Zendesk, HubSpot, Salesforce, and WordPress. A free plan offers basic checks, AI suggestions, limited paraphrasing, shortcuts, and a browser extension. Pro is $140.00 per year, billed annually. Business costs $5.00 per member per month, billed annually, and requires at least two seats; it adds shared style guides and shortcuts, analytics, centralized billing, and team management.

Linguix combines writing checks, editing suggestions, and shortcuts across web, mobile, and browser extensions. Business adds shared team resources, but requires at least two seats.

Linguix suits individuals who want writing checks and suggestions across supported apps and websites. Its Business plan is aimed at Marketing, Sales, HR, and Customer Support teams that need shared tools and team management.

Linguix is a writing assistant for people who want to correct and refine text across their usual apps, with a separate set of shared tools for teams. It is most compelling when grammar checks, rewriting, and team consistency matter together; its annual billing and Business seat minimum are meaningful trade-offs.

Overview

Linguix brings grammar and spelling checks together with AI suggestions, paraphrasing, rewriting, and typing shortcuts. Tone detection and clarity suggestions extend it beyond proofreading, while its Content Quality Score evaluates sentence length, vocabulary complexity, and passive voice. Those tools can flag areas to revise, but they cannot decide whether a draft is accurate or appropriate for its audience.

The writing technology supports English, Spanish, Portuguese, German, French, and Polish. Linguix says it began as a Chrome extension in 2018; its current platforms include web, Android, iOS, browser extensions, and an API.

Key features

The Free plan covers grammar and spelling checks, basic AI suggestions, limited paraphrasing, typing shortcuts, and a browser extension. It is a sensible entry point for occasional corrections, but the paraphrasing limit makes it a weaker fit for people who regularly rework drafts.

Pro adds advanced grammar and style suggestions, AI writing help, advanced paraphrasing and rewriting, unlimited typing shortcuts, clarity and tone suggestions, and priority support. That fuller toolkit is better suited to frequent writers who want both correction and revision help. Business includes Pro for each teammate, plus shared style guides and shortcuts, team analytics, centralized billing, and team management. Those shared controls are useful for organizations trying to keep communications consistent, though a two-seat minimum makes Business unsuitable for a solo user.

Extensions are listed for Chrome, Firefox, Edge, Safari, Opera, and Brave. Integrations include Gmail, Outlook, Google Docs, Google Sheets, Slack, Notion, Zendesk, HubSpot, Salesforce, and WordPress, which gives Linguix reach across common writing and customer-facing workflows.

Pricing

Free: free, billed Forever. It includes grammar and spelling checks, basic AI suggestions, limited paraphrasing, typing shortcuts, and a browser extension. Choose it for basic checks; it gives up Pro's advanced suggestions, expanded rewriting, and unlimited shortcuts.

Linguix Pro: $140 a year, billed $140 annually. It adds advanced grammar and style suggestions, AI-powered writing help, advanced paraphrasing and rewriting, unlimited typing shortcuts, clarity and tone suggestions, and priority support. The annual charge suits regular users willing to commit for a year. Subscribers can cancel anytime, with access continuing through the current billing period.

Linguix Business: $5 a month, billed annually at $5 / member / month, with a minimum of 2 seats. It includes everything in Pro per teammate and the shared team tools. Seats can be managed anytime, but the initial two-seat requirement means a one-person operation cannot buy the plan alone.

New purchases have a 10-day money-back window; subscription renewals are non-refundable. The annual billing terms matter on both paid plans, even though Business is priced per member per month.

Platforms

Linguix is listed for Android, iOS, web, browser extension, and API. Its broad browser coverage and integrations make it a practical choice for writing across services rather than only in one editor. The mobile apps extend access beyond desktop, while the platform list alone does not establish that every feature works identically in every environment.

Who it's for

Individual writers who want more than spelling correction can use Pro for style guidance, rewriting, tone suggestions, and shortcuts. The Free plan is a better fit for light use where basic checks are enough. Business is aimed at Marketing, Sales, HR, and Customer Support teams that want shared writing guidance and administrative oversight, provided they need at least two seats.

Pros and cons

• Pros: Combines correction, rewriting, tone and clarity suggestions, and shortcuts, so writers can address several stages of a draft in one tool.
• Pros: Business adds shared style guides, team shortcuts, analytics, and centralized management for organizations coordinating multiple contributors.
• Pros: Supports six languages and lists extensions for six browsers, alongside integrations with common work and communication apps.
• Cons: Free paraphrasing is limited, so regular rewriting calls for a paid plan.
• Cons: Pro is billed annually, and Business requires at least two seats, raising the commitment for individuals and small teams.
• Cons: Renewal payments are non-refundable, despite the 10-day money-back window for new purchases.

LanguageTool is another freemium writing checker, with extensions and apps for iOS, macOS, and Windows; choose it if those platforms or its character-based plan limits better fit your workflow.

Verdict

Linguix is the strongest fit for writers who want checks and rewriting in their workflow, or teams that need shared language guidance and oversight. Its combination of correction, style suggestions, shortcuts, and Business controls is the main reason to choose it. Look elsewhere if you need a monthly individual subscription, cannot accept annual billing, or would be forced into a second Business seat.
