Table of contents

We are proud to announce our new line of Task-Specific APIs, with the launch of the Wordtune API set, giving developers access to the language models behind our massively popular consumer-facing reading and writing apps. 

Wordtune and Wordtune Read both use cutting-edge AI to assist users with writing and reading tasks – all while saving time and improving performance. With the release of Wordtune API, we’re giving developers access to the AI engine behind this award-winning line of applications, allowing them to take full advantage of Wordtune’s capabilities and integrate them into their own apps:

  • Paraphrasing API - Reword texts to fit any tone, length, or meaning.
  • Summarize API - Condense lengthy texts into easy-to-read bite-sized summaries.
  • Grammatical Error Correction API - Catch and fix grammatical errors and typos on the fly.
  • Text Improvements API - Get recommendations to increase text fluency, enhance vocabulary, and improve clarity. 
  • Text Segmentation API - Break down long pieces of text into paragraphs segmented by distinct topic.

Faithfulness rates measure how factually consistent a summary is with the original text. As you can see below, our new Summarize API has reached a faithfulness rate that outperforms OpenAI’s Davinci-003 by 19%.
