Curlsbot was originally just a side project built in Glitch as a chatbot, but I've slowly turned it into a website.
The bot was a Facebook Messenger bot that people could message with hair product ingredient lists and it would analyze them. I wrote an article about my experience building the bot for Code Like A Girl
I loved how the bot allowed me to interact with the users personally and talk to them about different features they wanted. I grew to over 300 users even though I kept it in testing mode. But I realized the experience would be better on a website. So I migrated it over to a GatsbyJS site.
The site now has articles, a quiz, and the original ingredients analyzer, and I keep adding new info and tools every month.
