Marketing Wise has delivered 30+ LLM integration projects for SaaS products, eCommerce companies, professional services firms, content businesses, healthcare platforms, and enterprise internal tools across Noida, Delhi, and Gurugram. Our LLM builds include AI-powered content generation, document analysis and extraction, customer support automation, intelligent search, sales email drafting, contract review assistance, and AI features embedded inside existing web and mobile products.

We build LLM integrations with four engineering principles: the right model for the task (Claude for nuanced writing and analysis, GPT-4o for multimodal inputs, Gemini for long-context document work, Llama for on-premise deployments where data cannot leave the network), prompt engineering that produces reliable outputs (system prompts, few-shot examples, output formatting, and guardrails that make the LLM behave consistently in production, not just in the demo), context injection that gives the model your data (RAG, tool calling, and structured context passing so the LLM responds based on your business data rather than its training data alone), and cost and latency management (model selection, caching, streaming responses, and token optimisation that keep the feature fast and economically viable at scale).
