Frequently Asked

Questions

It is building web apps on MongoDB, Express.js, React and Node.js with AI features like LLMs, chatbots and recommendations built into the product. KriraAI designs the AI layer into the architecture from day one.

Yes. Node.js handles AI API calls and real-time streaming, MongoDB stores chat data and embeddings, and React delivers the AI interface. For custom model training, we add a Python service.

We connect it on the Node and Express backend so API keys stay secure, stream responses to the React UI, and add rate limiting, prompt protection and cost monitoring.

MERN is better for fast, real-time AI products like chatbots and SaaS apps. Python is better for heavy model training. Many projects use both together.

We integrate OpenAI GPT, Claude, Gemini and open-source models like Llama and Mistral, chosen by accuracy, speed, privacy needs and cost.

RAG (Retrieval-Augmented Generation) lets an LLM answer from your own data, which reduces wrong answers. Yes, we build it using MongoDB Atlas Vector Search or Pinecone.

An AI MVP and a larger AI platform take different amounts of time, depending on features and integrations. You get a timeline after discovery.

Cost depends on AI feature complexity, LLM usage, integrations and team size. Share your requirements for a free custom quote.

We use encrypted storage, role-based access, server-side API key management and PII masking before data reaches any LLM. Your data is not used to train public models.
