The service also describes extracting text from recordings and images, rewriting extracted text, and paraphrasing speech in real time. The homepage lists support for more than 20 languages, while API documentation lists 13+ languages for API use. Several modes are free; the pricing explanation gives a 600-word limit, and says upgrading to Pro can increase the limit to 1500. Apps and API options span Android, iOS, and web. The full-article API endpoint accepts up to 5000 characters per content check. The maker identifies students, freelancers, academic writers, and SEO content creators as intended users.

Rephrase AI is a web and API paraphrasing tool that rewrites text while preserving its original meaning. It automatically detects language and supports English, Russian, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, and Korean. The maker says important keywords can be retained while content is refreshed for SEO. Students, writers, content marketers, bloggers, and SEO teams are listed use cases. The free plan costs nothing and allows three rephrases per day, with 500 characters per rephrase and no credit card requirement. The Yearly Plan costs $4.99 a year, billed at $4.99 a month or 59.88 USD annually; the Monthly Plan costs $9.99 a month. Both paid plans include unlimited text length, language selection, personal-key API access, priority support, and no rate limits. The monthly plan can be cancelled anytime. Rephrase AI says text is not stored after processing and communications are encrypted, while its privacy notice says AI providers, including OpenAI, may process submitted information.
