FAQ
How do you ensure my data is private and secure?
Data privacy is a top priority. Your documents and vectors stay in a secure environment, either your own cloud or a private setup.
What is the typical delivery time for a custom chatbot?
Delivery time depends on project scope and data complexity. A basic RAG chatbot (with a small set of documents) can often be delivered in about a week or so. If you have lots of content (multiple PDFs, large Notion databases, etc.) or need extra customization, it might take a bit longer.
Will I own the code and model after the project is done?
Absolutely. You get full ownership of everything. I’ll provide all the source code, the fine-tuned model files (for open-source models), and instructions so you can run or modify the bot as you wish.
Can the chatbot handle multiple languages?
Yes, I can make it multilingual.
Can it integrate with my existing tools (CRM, Slack, Notion, etc.)?
Definitely. Using LangChain and other connectors, I can hook your chatbot into most platforms.
How do you handle document ingestion and vector DB setup?
I handle all of it. You just give me your documents (PDFs, Notion pages, websites, etc.), and I use LangChain’s loaders to import them. The text is automatically chunked, embedded, and stored in a vector database (like Pinecone).
