Spellcheck and Levenshtein distance
polyleven is the fastest Levenshtein distance library I've been able to find. It also has a threshold parameter which can be used to speed up the calculations. That being said, I've had a lot more success speeding up the processing of large text datasets by converting the words to a vector space (using e.g. word2vec) then calculating euclidean distance, which is much faster than calculating Levenshtein distance (assuming you are using vectorized operations). The fastest solution would probably be to use approximate nearest neighbor search (see for example the faiss library), but again you'll have to embed your words in a vector space and you'll need to decide if this is viable for your use case.
