RiTa

Designed to support the creation of new works of computational literature, the RiTa^† library provides tools for artists and writers working with natural language in programmable media. The library is designed to be simple while still enabling a range of powerful features, from grammar and Markov-based generation to text-mining, to feature-analysis (part-of-speech, phonemes, stresses, etc). All RiTa functions are heuristic and do not require training data, thus making the core library quite compact. RiTa can also be integrated with its own user-customisable lexicon, or with the WordNet database. RiTa is implemented in both Java and JavaScript, is free/libre and open-source, and runs in a number of popular programming environments including Android, Processing, Node, and p5.js.

^† from the old Norse, meaning to mark, scratch, or scribble
