Livecoding an SMS Chatbot

on YouTube ↗16m

" summary

Live-codes an SMS/MMS chatbot that impersonates a Twitter celebrity using markov chains, pulling up to 3,000 historical tweets via the Twitter gem (200 per request), cleaning out links/RTs/hashtags, and seeding a Markov model (marky_markov) saved to CSV. Uses Sinatra + Twilio to reply to incoming texts with generated lines and send an image, and uses the Twilio REST API to place calls that play a repeated robot-voiced Markov sentence — demo works live and returns plausible, often funny, DHH-like output.
