15. One or more non-transitory computer-readable media comprising computer executable instructions that, when executed, cause at least one processor to perform actions comprising: receiving text of a message from a first user; generating a conversation feature vector using a first neural network and the text of the message from the first user; generating a first response feature vector using the conversation feature vector and a second neural network; generating a first plurality of suggested words using the first response feature vector, wherein the first plurality of words comprises a first suggested word; generating a second response feature vector using the first suggested word, the first response feature vector, and the second neural network; generating a second plurality of suggested words using the second response feature vector, wherein the second plurality of suggested words comprises a second suggested word; generating a suggested response to the message from the first user using the first suggested word and the second suggested word; and transmitting the suggested response for presenting to a second user.

The one or more non-transitory computer-readable media of claim 15 , wherein generating the conversation feature vector comprises encoding the message from the first user with a matrix of word embeddings and processing the encoded message with the first neural network.
