LanguageTool

Overview

LanguageTool is a writing assistant for people who want checks and rewrites across documents, email, and browser text. It suits multilingual individual writers as well as teams that need shared terminology; the trade-off is that the free tier is limited and paid-plan prices are custom pricing.

It combines grammar, spelling, punctuation, casing, style, paraphrasing, tone detection, and writing statistics, with support for 31 languages. Use it through a browser extension, desktop and iOS apps, or integrations with word processors and email services.

Key features

Corrections and rewrites

The free version handles spelling, simple punctuation, and some style mistakes, making it useful for a basic pass rather than comprehensive editing. Broader writing checks include grammar, casing, and style suggestions, while tone detection and writing statistics add ways to assess a draft. The paraphraser can make sentences more formal, fluent, simple, or concise; that range is useful for adjusting wording without switching tools.

Text-field limits vary sharply by plan: Basic allows 2,000 characters, while Premium supports up to 150,000. The larger limit is better suited to long documents; Basic is restrictive for substantial passages.

Integrations and text handling

LanguageTool works in common browsers and word processors, including Google Docs, Microsoft Word, Apple Pages, and LibreOffice. Email add-ons cover Gmail, Outlook, Apple Mail, and Thunderbird, so it can follow writing across several common contexts rather than being confined to a standalone editor.

Text entered through the browser add-on is usually not saved, while editor texts are saved and accessible across devices. That distinction favors the add-on for writing users do not want retained and the editor for work they want to revisit.

Team controls

Teams can invite and manage users by email, share style guides and dictionaries, and use brand voice controls to keep wording and terminology consistent. Business solutions are described as GDPR-conform. These controls make the team offering more relevant to organizations with shared writing standards than to individuals who only need corrections.

Pricing

LanguageTool uses a freemium model. The free plan covers spelling, simple punctuation, and some style mistakes. Basic allows 2,000 characters per text field; it is the lower-limit option for shorter writing, not a substitute for Premium when working with longer passages.

Individual Premium is offered monthly, quarterly, annually, or every two years, with up to 150,000 characters per text field on each term. The longer-term options provide a choice of billing interval, but prices are custom pricing. Premium includes a 14-day money-back guarantee, with cancellation and refund without questions.

The Team plan supports 20 users and up to 150,000 characters per text field, alongside team administration and shared style controls. It is the fit for groups coordinating terminology and brand voice; pricing is custom pricing.

Platforms

LanguageTool offers a browser extension, desktop apps for Windows and macOS, and an iOS app. It also integrates with the listed office suites and email services, giving writers multiple ways to use its checks within their existing workflows.

Who it's for

Choose LanguageTool if you need writing checks across several languages and contexts, or if a team needs shared dictionaries and style guidance. It is less compelling if the free checks are not enough and you need transparent Premium prices before choosing a paid plan.

Pros and cons

• Pro: Support for 31 languages and integrations across office and email tools make it useful beyond a single editor.
• Pro: Premium's 150,000-character field limit accommodates long text, while team style guides and dictionaries help groups maintain consistent wording.
• Pro: The 14-day Premium money-back guarantee lowers the commitment risk for individual subscribers.
• Con: The free tier is limited to spelling, simple punctuation, and some style mistakes, so it may not cover writers seeking fuller checks.
• Con: Paid prices are custom pricing, making it difficult to compare costs in advance.

Verdict

LanguageTool is a strong fit for multilingual writers and teams that need checks across documents and email, with shared style controls for coordinated work. Its broad integrations and large Premium text limit are the main reasons to choose it; look elsewhere if you need published paid prices or more capable checks without moving beyond the free tier.
