Building a product with AI tools

Cofounders and I have launched a saas company in 2018 (sold in 2022). We are launching a new venture, in saas as well. We’re very interested in leveraging AI capabilities to build our product faster (we’re in the MVP phase), we know the tools have changed a lot in the last couple of years. Which tools and resources would you recommend to bring me up to speed in that area? I’m particularly interested in the advice of cofounders who have launched a product in the past ~12 months and could give their feedback.
