SubredditSimulator uses Markov chains to generate text, not an neural network.

I have made my own subreddit using the same RNN tool as that post: https://reddit.com/r/SubredditNN

have you tried partnering with simulator so your posts are displayed there too? I imagine they would get more exposure and therefore better feedback

I believe development on SubredditSimulator is stalled now that the dev is no longer working at Reddit / is building a Reddit competitor.

Makes it more likely for him to agree :)
