FAQ
How is a tool-calling AI agent different from a chatbot?
A chatbot mainly answers. A tool-calling agent can use approved functions—such as searching records or creating a draft—to complete a defined workflow.
Which AI provider should I use: OpenAI or Claude?
I can work with OpenAI, Claude or another agreed API. I will recommend the practical option based on tool support, latency, data needs and budget.
Can an AI agent use tools to update app data?
Yes, but write actions are scoped explicitly and protected with validation, permissions and confirmation steps where appropriate.
Does AI agent integration include RAG or document chat?
A small existing data source can fit Standard. Large ingestion pipelines, complex RAG, OCR or multi-tenant knowledge bases require a custom offer.
Do you provide OpenAI or Claude API keys and model fees?
No. Keys and usage stay in the buyer's account. I build in test/development mode before go-live.
Can you improve an existing AI agent or AI feature?
Yes. Send the current behavior, codebase and the result you want.
