Text comparison API (Cloud function, Google cloud function or AWS lambda)

Job ID: 30872348

Budget: $30 – $250 USD

I want to have a text comparison API written with either Firebase cloud functions or AWS Lamda, which compares two sentences.
This API(function) gets an object or dictionary that has two strings and returns these results:
1- Similarity and difference percentage: how much the second sentence is different and similar from/to the first one
2- Missed spelled words: which words are missed spelled in the second sentence
3- What are the extra words, that are not in the first sentence
4- What are the words that do not exist in the second sentence
