LanguageTool vs TextGears

LanguageTool is a writing assistant that checks grammar, spelling, punctuation, casing, and style across 31 languages. It also offers tone detection, writing statistics, and paraphrasing modes for making sentences more formal, fluent, simple, or concise. The service works through browser extensions and Windows, macOS, and iOS apps, and integrates with Google Docs, Microsoft Word, Apple Pages, and LibreOffice. Email add-ons are available for Gmail, Outlook, Apple Mail, and Thunderbird. The free version covers spelling, simple punctuation, and some style issues, with a 2,000-character limit per text field; Premium allows up to 150,000 characters. Individual Premium can be billed monthly, quarterly, annually, or every two years, but no plan prices are listed. Text written through the browser add-on is usually not saved; text in the editor is stored and accessible across devices. Teams can manage invited users and share style guides and dictionaries. Business solutions are described as GDPR-conform and support consistent brand voice. Premium has a 14-day money-back guarantee with cancellation and refund without questions.

TextGears checks writing for spelling, grammar, style, and readability, through its website and API. The API also provides autocorrection, text analysis, language detection, summarization, and keyword extraction, returning JSON through HTTP or HTTPS requests. Its documentation lists 11 languages, including English, French, German, Portuguese, Russian, Italian, Arabic, Spanish, Japanese, Chinese, and Greek, as well as dialect codes such as en-US, en-GB, and pt-BR. A Postman collection and JavaScript library link are available for integration. Free access includes 500 requests per month, 200k characters per month, and a 4k-character request limit. PRO costs $2.48 a month and includes unlimited checks, translations, and paraphrases of long texts, custom dictionary rules, and an option not to store texts. TextGears says AI does not support every language and recommends standard plans when language breadth matters more than AI analysis quality. Readability metrics are recommended for texts of at least 30 words. The maker is headquartered in Tallinn, Estonia.
