Hey there, welcome to Bubble! 
Integrating Bubble’s database directly with OpenAI to process prompts is definitely achievable, and Bubble’s built-in tools like the API Connector and backend workflows should help you accomplish this pretty effectively. Initially, you could explore Bubble’s own API Connector to handle your data flows. While doing this, bear in mind a few points like rate limits, data security, and workflow optimization—breaking down API calls into manageable batches and incremental testing can save you a lot of headaches down the line.
If you’re tight on time or prefer not to spend extensive hours configuring API connections and managing detailed technical nuances, feel free to check out what we’ve built at Aicado (Disclaimer: I’m currently a product manager there, and you’ll notice that on my profile!). At Aicado, we provide a ready-to-use solution that integrates your Bubble data with your own OpenAI Asistant with external features (we called it Super Agent), with an intuitive interface for your users, eliminating a good portion of the heavy lifting in the integration process.
Whichever route you pick, feel free to shoot me a message anytime—I’m here and more than happy to share additional insights, examples, or guidance for your project. Good luck and welcome again to the community!
