Overview

TextGears combines a browser-based checker with an API that handles more than corrections: it can autocorrect, assess readability, detect language, summarize text, and extract keywords. That breadth makes it a stronger fit for product workflows than a grammar-only endpoint. The trade-off is that its AI does not cover every supported language, so teams prioritizing language breadth over AI analysis should favor standard plans.

The API accepts HTTP or HTTPS requests and returns JSON. A Postman collection and JavaScript library link give developers practical integration starting points. Customers can select a cluster in the United States, Estonia, or Singapore, each with a stated 99.9% availability guarantee. TextGears says it is GDPR ready and does not share customer data with third parties.

Key features

The API documentation covers 11 languages: English, French, German, Portuguese, Russian, Italian, Arabic, Spanish, Japanese, Chinese, and Greek. Dialect codes include en-US, en-GB, en-ZA, en-AU, en-NZ, fr-FR, de-DE, pt-PT, and pt-BR. This is useful for multilingual services, but the AI language caveat matters when a workflow depends on consistent AI analysis across those languages.

Readability metrics are more dependable on sufficiently substantial input: TextGears recommends at least 30 words because accuracy depends on text size. That makes the feature less suitable for scoring very short snippets in isolation. Style suggestions are supported, and the maker also documents a website plugin; its current version cannot attach to a textarea element, limiting its usefulness for common embedded form workflows.

Support is offered in English and Russian, and TextGears says it answers 96% of requests within 24 hours. The maker reports that more than 830 companies use the API and that it handles over 10.8 million requests per day, a signal of established usage rather than a substitute for checking fit against a team's own requirements.

Pricing

The Free plan costs 0.00 USD per free, billed monthly, and allows 500 requests per month, 200k characters per month, and 4k characters per request. It is a sensible way to validate an integration or serve a low-volume use case, but the monthly request ceiling and per-request cap can constrain production workloads.

PRO costs 2.48 USD per month and offers unlimited checks, translations, and paraphrases of long texts, custom dictionary rules, and an option not to store texts. It is the lowest-cost paid plan and suits users needing those capabilities without the metered checking quotas shown on Silver and Gold.

Silver costs 29.95 USD per month and includes 50k text-checking requests per month, 20000k translation or rephrasing characters per month, requests up to 4k characters, and a 0% payment fee. Dictionary setup is unavailable, so teams that need custom rules should look at PRO or another suitable tier.

Gold costs 99.95 USD per month, with 500k text-checking requests per month, 100000k translation or rephrasing characters per month, requests up to 16k characters, and a 0% payment fee. Its higher quotas and longer request limit suit heavier workloads. Platinum has custom pricing and offers millions of text-checking requests, individual character quotas and request lengths, 24/7 support, usage statistics, and AI.

Platforms

TextGears is available as an API and on the web. The API is the more compelling option for teams integrating checks into a product; the web checker serves direct text analysis. The documented plugin's inability to attach to a textarea limits one route to adding checks to an existing page.

Who it's for

TextGears identifies EdTech, HR, content and advertising services, universities, and students as potential users. Its API breadth is especially relevant to builders who want language checks plus summarization or keyword extraction in one integration. Teams should weigh the AI language caveat, text-size requirement for readability, and their expected monthly volume before committing.

Pros and cons

Pros: The API combines grammar and spelling checks with autocorrection, readability, language detection, summarization, and keyword extraction, reducing the need to assemble separate text-analysis functions.
Pros: HTTP or HTTPS and JSON, plus a Postman collection and JavaScript library link, provide clear integration entry points; selectable clusters and a 99.9% availability guarantee per cluster add deployment options.
Pros: Free access and a 2.48 USD-per-month PRO plan give teams low-cost ways to start, with PRO adding custom dictionary rules and an option not to store texts.
Cons: AI does not support all languages, which can make it a poor fit when broad language coverage must also extend to AI analysis.
Cons: Free is capped at 500 requests monthly and 4k characters per request, while Silver lacks dictionary setup; teams must choose around quotas and required controls.
Cons: Readability metrics are recommended for texts of at least 30 words, and the current plugin cannot attach to a textarea element, limiting short-text scoring and some page integrations.

Alternatives

For a focused readability tool, compare the Readability Checkers directory; for correction-first options, see Grammar checkers.

Choose Text Inspector when its free 250-word plan and automatic deletion after six hours better match a small, privacy-conscious check; it also offers a free trial and API and web access. Readable is a paid API and web option with a free trial; its ContentPro plan is 12.00 USD per month, billed as $48 annually, for one user, with no website slots or API access listed.

ProWritingAid is worth considering for writers who prefer an extension and can work within its free limits of 500 words per report run and two report runs per day. For a free web checker that runs in the browser and works offline after loading, consider AnchorKite Readability Checker. Check Readability is another free web and extension option with no account requirement or usage fees, for personal and commercial use.

Data·yze Readability Analyzer is a free, ad-supported web app with no usage limit stated on its page. Delimiter Readability Checker offers a free web tool without an account or paywall. Readability Formulas is a freemium option spanning web, extension, macOS, and Windows.

Verdict

TextGears is a strong choice for teams that want a broad text-analysis API, selectable hosting regions, and a low-cost path from evaluation to paid use. Its mix of correction, readability, and analysis functions is the main reason to choose it; look elsewhere if AI must work across all supported languages, if your integration depends on the documented textarea plugin, or if your expected traffic exceeds the plan caps without fitting a higher tier.
