Tinq AI - NLP API

Tinq.ai is a natural language processing toolkit offered as a REST API alongside a set of ready-to-use web tools. The core capabilities include multilingual rewriting and paraphrasing, plagiarism checking, sentiment analysis, named-entity recognition, summarization, and content extraction. Developers can call these capabilities directly through the API to add NLP features to their own applications, while non-developers can use the hosted tools such as the paraphraser and rewriter directly on the site. Beyond the raw NLP endpoints, Tinq.ai also packages a writing-assistant layer aimed at content creators: an AI article writer, a content rephraser, a title generator, and a meta description generator, intended to speed up producing blog posts, marketing copy, and similar text. The paraphrasing tool in particular is built to restate a sentence, phrase, or full passage while preserving its original meaning in a new form. The API integrates natively with Zapier, Gmail, Google Sheets, and Google Forms, making it usable in no-code workflows as well as custom code. Tinq.ai offers a free tier that doesn't require a credit card, and the company states it serves millions of API requests each month across thousands of developers, though pricing for higher usage tiers isn't detailed on the homepage.
