Writing texts, especially in a foreign language, often requires a person, either a lector or a native speaker, to suggest text enhancements in real time. InstaText enables this in the form of a web-based application where the users enter their text on the left and receives a suggestion of improved text on the right, with clearly marked corrections and editing. Modified text may contain grammatical and other corrections, improved vocabulary, and more appropriate use of words, and may include thorough text transformations and text optimization. InstaText enables the automatic refinement of texts in different languages through the use of artificial intelligence and language technologies.
