Momento's Developer Ecosystem team developed RoboMo, a Discord bot designed to assist users by answering questions related to Momento developer documentation and blog posts through a combination of Momento Vector Index and OpenAI. Although the Momento Vector Index was deprecated in April 2024, the article provides a detailed walkthrough of the bot's creation, which includes setting up a Discord bot application, utilizing the discord.js library to interact with the Discord API, and deploying the bot using AWS Fargate for continuous operation. RoboMo listens for mentions and utilizes a question-answering system to provide responses, with all related code available on GitHub for those interested in creating similar bots.
