FAQ
Which framework should I choose, LangChain or LangGraph?
LangChain is a good choice for simpler agents and tool integrations. LangGraph is better for advanced multi-step workflows, branching logic, and more controlled agent behavior. I can recommend the right one based on your use case.
Can you build agents that use external tools or APIs?
Yes. I can build agents that interact with APIs, databases, external services, search tools, and other custom workflows depending on your project requirements.
Can you integrate the AI agent into my existing app or backend?
Yes. I can integrate the agent into your existing backend or build an API layer so your frontend, SaaS app, or internal system can use it easily.
Do you support memory and conversation history?
Yes. I can add short-term or structured memory depending on the workflow and the type of experience you want for users.
