AI & LLM App Development

We integrate ChatGPT, Claude, Gemini and custom AI models into production-ready mobile and web applications.

LIAWEB specializes in integrating large language models (LLMs) and AI capabilities into mobile and web applications. We work with OpenAI, Anthropic, Google, and open-source models to build intelligent features that transform user experiences.

From simple chatbot integrations to complex multi-agent AI systems with RAG pipelines and custom fine-tuning, we architect AI solutions that are production-ready, cost-optimized, and secure. Our team stays at the cutting edge of AI development, adopting new models and techniques as they emerge.

AI Development Capabilities

Conversational AI

Build intelligent chatbots, virtual assistants, and natural language interfaces powered by GPT-4, Claude, or Gemini — with streaming responses and context-aware conversations.

Custom AI Workflows

Design complex AI pipelines with RAG (Retrieval-Augmented Generation), multi-agent systems, function calling, and tool use for business-specific automation.

Content Generation

AI-powered content creation, summarization, translation, and analysis integrated directly into your app workflow — from documents to images.

Secure AI Architecture

Enterprise-grade security with API key management, rate limiting, content moderation, PII filtering, and SOC 2 compliant infrastructure.

Frequently Asked Questions

To integrate ChatGPT (OpenAI API) into a mobile app: create an OpenAI account and get an API key, build a secure backend endpoint (Node.js, Python) that proxies requests to the OpenAI API (never expose API keys in mobile apps), call your backend from the mobile app using HTTP requests, and stream responses for a real-time chat experience. LIAWEB handles this full integration including secure architecture.
AI-powered app development means building mobile or web applications that leverage artificial intelligence — specifically large language models (LLMs) like GPT-4, Claude, or Gemini — to provide intelligent features like natural language interfaces, content generation, smart recommendations, voice interaction, document analysis, and automated workflows.
Building an AI-powered app costs $25,000–$200,000+ depending on complexity. A simple chatbot integration costs $15,000–$35,000. A custom AI assistant with fine-tuned behavior costs $40,000–$100,000. A full AI-native app with multiple LLM features, custom training data, and complex workflows can cost $100,000+. LIAWEB provides detailed AI app cost estimates during free consultations.
The best AI model depends on your use case. OpenAI GPT-4o is ideal for general-purpose text, vision, and voice. Anthropic Claude is excellent for long documents and nuanced reasoning. Google Gemini integrates natively with Google services. For real-time features needing low latency, lighter models like GPT-4o-mini or Claude Haiku are recommended. LIAWEB evaluates the right model for each specific use case.
