Use Mastra to connect your AI model to various tools and APIs.
"A founder building a customer support chatbot with Mastra can integrate it with their Notion database to fetch customer information and log conversations in just 3 steps: connect their Mastra agent to Notion, define a trigger to fetch new customers, and set up a response flow to save the conversation. This lets the founder focus on improving the chatbot's responses."
