Frequently Asked Questions
What is an AI agent builder?
- An AI agent builder is a platform that lets you create AI assistants (called “agents”) that can perform specific tasks autonomously. Unlike basic chatbots, AI agents can follow multi-step instructions, access external tools and data, and be trained on specific business contexts to handle tasks like research, writing, customer support, and data analysis.
What is the best AI agent builder for non-technical users?
- For non-technical users, LaunchLemonade and Lindy AI are the most accessible options. Both offer no-code setup where you describe what you need in plain English. LaunchLemonade focuses on business task delegation with multi-model AI, while Lindy focuses on personal productivity automation.
How much do AI agent builders cost?
- AI agent builders range from free (open-source tools like CrewAI, or free tiers on Lindy and Voiceflow) to $25-$200/month for commercial platforms. LaunchLemonade starts at $20/month, Lindy at $49/month, Sintra at $97/month. Enterprise plans from Voiceflow and others can reach $500+/month.
Can I build AI agents without coding?
- Yes. Platforms like LaunchLemonade, Sintra AI, and Lindy AI let you build AI agents entirely without coding. You describe the agent’s role, upload training documents, and set instructions in natural language. For more complex agent systems with custom logic, platforms like Voiceflow offer visual builders, while CrewAI and LangChain require Python coding.
What’s the difference between an AI agent and a chatbot?
- A chatbot follows pre-defined conversation scripts and responds to specific inputs. An AI agent uses large language models to understand context, make decisions, and complete multi-step tasks autonomously. Agents can be trained on custom business data, access external tools, and adapt their approach based on the situation. Chatbots typically cannot.
