The Be Kind Bot is a GitHub bot designed to encourage kindness on the internet by identifying rude comments, suggesting alternatives, and pinging repository owners if necessary. The project was initiated during an internal hack week at Sentry, with the goal of promoting more participation in open-source software. Despite using sentiment analysis and machine learning APIs, the team encountered challenges in accurately identifying abusive comments due to context sensitivity and nuances of language. A prototype was built on Probot, a GitHub app framework, which can be easily extended and improved upon. The Be Kind Bot aims to contribute to building more inclusive online communities by providing a starting point for open-source project maintainers to develop their own tools and strategies for promoting kindness on the web.
