TextGears is a text-analysis platform best known for its grammar checking API, helping developers and companies add proofreading to their own products.
Alongside a free online checker for quick manual proofreading, TextGears provides APIs for grammar and spelling correction, paraphrasing and translation across more than eleven languages, including English, French, German, Portuguese, Russian, Italian, Arabic, Spanish, Japanese, Chinese and Greek. It scores readability, evaluates vocabulary richness, produces an overall correctness assessment, and understands dialect differences between countries that share a language. Typical customers include EdTech companies checking student essays, HR platforms screening resumes, and content and advertising services verifying text before publication. Business plans add GDPR compliance, an SLA and even on-premise deployment for sensitive content. The API returns structured results with error types, positions and suggested corrections, so developers can build their own editing interfaces instead of embedding a generic widget, and usage is priced by request volume rather than per seat. Response times are fast enough for as-you-type checking inside editors, and the platform is designed to scale from a classroom side project to millions of monthly requests on the Platinum tier.
A free tier includes 500 text-checking requests per month and a monthly allowance of characters for translation and rephrasing. Silver costs $23.96 per month for 50,000 requests, Gold costs $79.96 per month for 500,000 requests with longer texts per request, and Platinum offers custom volumes and terms for enterprises.
Developers, EdTech and content platforms, HR tools, and businesses that need grammar checking and text analysis embedded in their own software.
