How to Build AI Apps: The Top 21 Low-Code Platforms

Forget building AI from scratch – a new era is dawning where almost anyone can deploy intelligent applications. The rise of low-code and no-code AI platforms is fundamentally shifting the landscape of artificial intelligence development, moving it away from a domain solely occupied by specialized programmers and towards a world where business users, marketers, and even citizen developers can harness the power of AI. Recent research, compiled from a deep dive into 21 leading platforms – a list detailed in a MarkTechPost article published June 7th, 2026 – reveals a staggering shift: these tools are now capable of translating simple prompts into fully functional AI agents, sophisticated automation workflows, and even trained machine learning models, drastically reducing the technical barriers to entry. This isn’t just about simplified interfaces; it’s about a fundamental reimagining of how AI is created and deployed.

The MarkTechPost report identified 21 platforms, ranging from established players like OutSystems and Microsoft Power Apps to newer, more specialized offerings like Bubble AI and Cognigy. These platforms cover a diverse range of applications, including AI-powered chatbots, automated data analysis tools, predictive maintenance systems, and even custom-trained machine learning models for niche industries. Several key metrics emerged from the analysis: the average development time for an AI-powered application has plummeted from an estimated 6-12 months with traditional methods to just 2-4 weeks using these low-code solutions. Furthermore, the cost of development has seen a decrease of nearly 60%, largely due to the reduced need for specialized AI engineering talent. Companies like DocuSign and Salesforce are already piloting several of these tools, with DocuSign reportedly using a no-code platform to build an AI agent that automates contract review and Salesforce exploring low-code solutions for enhanced customer service chatbots. The platforms themselves are seeing explosive growth; Bubble AI, for instance, reported a 300% increase in user sign-ups in the last quarter alone, driven largely by small businesses and marketing agencies.

What This Actually Means

The significance of this shift cannot be overstated. For decades, building AI has been a complex, expensive, and time-consuming undertaking, typically requiring large teams of highly skilled data scientists and engineers. Now, businesses can rapidly prototype and deploy AI solutions without needing to overhaul their entire IT infrastructure or hire a dedicated AI team. This democratization of AI represents a fundamental change in the competitive landscape, leveling the playing field and allowing smaller organizations to compete with larger corporations that previously held a significant advantage. Before, a company needed to invest in building a massive data science team and potentially purchase expensive AI infrastructure. Now, they can leverage a platform like Cognigy to build an intelligent automation workflow that addresses a specific business need – and do it in a fraction of the time and cost.

Consider the impact on a small e-commerce business. Previously, they might have needed to hire an AI consultant to build a recommendation engine or a chatbot for customer support. Today, they can use a no-code platform like Appy Pie AI to build a personalized recommendation engine or a chatbot that handles frequently asked questions, freeing up their staff to focus on core business activities. Similarly, a marketing agency can rapidly prototype and deploy AI-powered content creation tools, automating tasks like social media post generation and email marketing campaigns. Even individual entrepreneurs can leverage these platforms to build AI-powered productivity tools, streamlining their workflows and boosting their efficiency. The accessibility of these tools isn’t just about cost; it’s about empowering individuals and small businesses to solve problems with AI in ways that were previously unimaginable.

This trend directly feeds into the broader AI race, which is increasingly focused on accessibility and usability rather than simply achieving the highest levels of model accuracy. The competition isn't just between tech giants like Google and Microsoft; it’s also between these low-code platforms vying to become the dominant tools for deploying AI. The shift towards low-code/no-code AI is accelerating the pace of innovation, allowing for faster experimentation and quicker iterations. It’s a strategic move for major tech companies, who are all investing heavily in their own low-code AI offerings to capture a piece of this growing market. This democratization also has implications for the future of education, potentially leading to new courses and training programs focused on utilizing these platforms to build AI solutions.

Why This Changes Everything

Looking ahead, one critical development to watch is the increasing integration of these low-code AI platforms with generative AI models. Currently, many platforms offer limited support for directly training custom machine learning models. However, the next few months will likely see a surge in platforms that seamlessly integrate with models like GPT-6 (the successor to OpenAI’s GPT-5) and similar large language models, allowing users to leverage the power of generative AI directly within the low-code environment. This will unlock entirely new possibilities, allowing users to create truly intelligent applications that can learn and adapt in real-time, fundamentally changing the nature of AI development. It begs the question: will these platforms ultimately become the primary interface for interacting with the most advanced AI models, or will a return to more traditional coding methods ultimately prevail?
