In this interview, we speak with Nemanja Divjak, the creator of Flow33, to learn more about their visual workflow builder for AI content generation. Flow33 combines multiple top-tier AI models to empower creators and businesses to easily produce professional video content at scale without needing expensive videography budgets. Flow33 What does Flow33 do? And why is now the time for it to exist? Flow33 is an AI content generation platform with a visual workflow builder, AI actors, and UGC video creation. It combines multiple AI models (GPT, Veo 3.1, Sora 2, Seedance) with pay-per-use credits, enabling creators and businesses to produce professional video content at scale. Now’s a good time for Flow33 to exist because AI video models are advancing rapidly, creating a strong demand for a unified, accessible interface that simplifies complex content generation for creators of all technical levels. What is your traction to date? How many people does Flow33 reach? Flow33 reaches thousands of content creators and businesses monthly through our platform, social media presence across X, Instagram, YouTube, LinkedIn, and TikTok, and organic search traffic. Growing user base with active paying customers using credits for AI video generation. Who does your Flow33 serve? What’s exciting about your users and customers?

Flow33 enables anyone to create UGC-style videos, AI actor content, and visual workflows without hiring videographers or editors. Notable use case: solo entrepreneurs and small teams producing studio-quality content on a budget. What technologies were used in the making of Flow33? And why did you choose ones most essential to your techstack? Flow33 relies on a scalable cloud foundation built with Next.js, Node.js, and Google Cloud Platform (GCP). These technologies were essential for orchestrating sophisticated AI/ML pipelines and seamlessly integrating state-of-the-art models like OpenAI's GPT-4o, Sora 2, and Google's Veo 3.1 into an intuitive Visual Workflow Builder. What is traction to date for Flow33? Around the web, who’s been noticing? Flow33 is currently operating as a live production platform, leveraging a pay-per-use credit system that is actively generating real transactions and growing MRR. The project is also working to establish its community footprint with ongoing content, tutorials, and social engagement across X, Instagram, and YouTube. What excites you about this Flow33's potential usefulness? Flow33 democratizes professional video content creation. Previously, producing AI-powered UGC videos, AI actors, and multi-model visual workflows required technical expertise and expensive tools. Flow33 makes it accessible to anyone with a browser — pick your AI models, build your workflow visually, and generate content in minutes.
