RAGTime is an open-source bot developed by Vectara that enables users to interact with their Slack or Discord communities using a chatbot powered by the company's RAG platform. The bot listens to user messages and responds with relevant answers, providing features such as one-to-one chats, contextual conversations in threads, and personalized responses. To use RAGTime, users need to sign up for Vectara, create a corpus, ingest data into it, and follow step-by-step instructions to run the bot on their server and connect it to their Slack or Discord community. The bot is built using Python and SQLite, leveraging Slack Bolt and Discord.py to handle events, and uses Vectara's Query API to process natural language input and return precise responses.
