LanguageTool

Overview

LanguageTool is a multilingual writing assistant for people who want corrections across their browser, office documents, email, and dedicated apps. It suits individuals and teams who need more than spelling checks, though the free tier is best for short, basic corrections.

Its range of integrations and paraphrasing modes make it a capable everyday editor; the trade-off is that meaningful use on longer texts requires Premium, whose pricing is custom rather than stated here.

Key features

Corrections and rewriting

LanguageTool supports 31 languages and covers grammar, spelling, punctuation, casing, style, paraphrasing, and writing statistics. Tone detection and style suggestions help users look beyond basic errors, while the paraphraser can make sentences more formal, fluent, simple, or concise. Those options suit writers refining drafts, but the free plan only covers spelling, simple punctuation, and some style mistakes.

The Basic plan's 2,000-character field limit is restrictive for full-length documents. Premium raises that ceiling to 150,000 characters per text field, a substantial upgrade for long drafts; the stated monthly word limit is 150,000 words.

Editing across devices and teams

Browser add-on text is usually not saved, while text entered in the editor is saved and accessible from all devices. That distinction favors the editor for work you need to return to, and the add-on for text you do not want retained there. Office integrations cover Google Docs, Microsoft Word, Apple Pages, and LibreOffice; email add-ons cover Gmail, Outlook, Apple Mail, and Thunderbird.

Teams can invite and manage users by email, and share style guides and dictionaries. Business solutions are described as GDPR-conform and support a consistent brand voice, making the team offering more relevant to organizations than to solo writers.

Pricing

LanguageTool is freemium. The free plan is useful for basic checks, but it does not match Premium's broader writing coverage or 150,000-character field allowance. Basic has a 2,000-character limit per field. Premium is offered monthly, quarterly, annually, or every two years, with each option supporting 150,000 characters per field; the listed plans have custom pricing. Premium includes a 14-day money-back guarantee, with cancellation and refund without questions.

The Team plan supports 20 users and the same 150,000-character field limit, also at custom pricing. It is the sensible fit when shared terminology and brand voice matter across a group; individuals do not need its team administration. Support is available, including for business VAT invoice questions.

Platforms

LanguageTool has browser extensions, desktop apps for Windows and macOS, and an iOS app. Its browser, office, and email integrations let users apply checks in common writing environments rather than relying only on a standalone editor.

Who it's for

Choose LanguageTool if you write across several apps or languages and want correction, style guidance, and sentence-level rewriting in one service. It is also a strong fit for teams that need shared dictionaries and style guides. It is less compelling for anyone who only needs occasional basic proofreading, or who requires a published Premium price before committing.

Pros and cons

• Pros: Support for 31 languages and integrations across major office and email tools make it useful in varied writing workflows.
• Pros: Premium's 150,000-character field allowance accommodates long texts, while paraphrasing offers four distinct rewrite directions.
• Pros: Team dictionaries, style guides, and brand voice controls address consistency across group writing.
• Cons: The free plan is limited to spelling, simple punctuation, and some style mistakes, and Basic's field limit is only 2,000 characters.
• Cons: Premium and Team pricing is custom, so shoppers cannot compare a stated price against their expected use.

Verdict

LanguageTool is a strong choice for multilingual writers who want corrections, rewriting, and broad app integrations, or teams that need consistent terminology and voice. Its clearest advantage is the combination of 31-language support and a 150,000-character Premium field limit. Look elsewhere if transparent paid pricing or a genuinely full-featured free tier is essential.
