Veelgestelde vragen
Do I need to provide an OpenAI or any other API key?
Yes, for GPT-4o or other paid APIs based builds you will need your own API key. Alternatively, I can build with fully open-source models (Mistral, LLaMA) at no API cost, just let me know your preference.
What file types do you support?
PDF, Word (.docx), plain text (.txt), CSV, and website URLs via web scraping. If you have a different format, message me and I will confirm compatibility.
Can this be integrated into my existing website or app?
Yes. The Standard and Premium packages include a FastAPI backend with REST endpoints, making integration with any website straightforward.
Will I own the source code?
Absolutely. You receive 100% of the source code, fully commented and documented, with no usage restrictions.
Can you handle large document collections?
Yes. I use chunking strategies and efficient vector indexing (FAISS/ChromaDB) to handle large corpora. For very large datasets, discuss your requirements before ordering so I can recommend the right approach.
