## Keras vs NLTK

When assessing the two solutions, reviewers found Keras easier to use. However, NLTK is easier to set up and administer. Reviewers also preferred doing business with NLTK overall.

- Reviewers felt that Keras meets the needs of their business better than NLTK.
- When comparing quality of ongoing product support, reviewers felt that NLTK is the preferred option.
- For feature updates and roadmaps, our reviewers preferred the direction of Keras over NLTK.
