Hire AI Developers: Custom AI & LLM Development

Part of our custom software development series.

Quick answer: AI development means adding machine learning, large-language-model (LLM) features, chatbots and automation to your product or operations. Hire AI developers when you want to build AI-powered features — not just bolt on a generic tool. WiseGuyXL builds custom AI features (LLM integrations, RAG, automation) into web apps.

What AI is best for

  • LLM-powered features (chat, search, summarization)
  • Retrieval-augmented generation (RAG) over your own data
  • AI chatbots and support assistants
  • Workflow and document automation
  • Predictive models and recommendations

What we build with AI

  • AI features inside SaaS and web apps
  • Internal AI tools that cut manual work
  • Chatbots grounded in your knowledge base (RAG)
  • Automations that connect AI to your systems

When to choose AI

Choose custom AI development when a generic tool can’t use your data or fit your workflow — for example, an assistant grounded in your own documents (RAG), or automation wired into your systems. Start with a focused, high-value use case (an MVP) to prove ROI before expanding. Most AI features are built on a Python or Node backend with an LLM API.

Cost, timeline and how we work

A AI project follows the same ranges as any custom build — roughly $25,000–$150,000+ over 6–20 weeks. Estimate yours with the cost calculator and timeline estimator. We scope, design, build in sprints, and you own the code — see our software development service and the complete guide to custom software.

FAQ

What can AI developers build?

LLM-powered features (chat, search, summarization), RAG assistants grounded in your data, chatbots, predictive models, and automation wired into your systems.

What is RAG?

Retrieval-augmented generation – grounding an LLM in your own documents/data so answers are accurate and specific to your business.

How much does AI development cost?

Like other custom builds, typically $25,000-$150,000+ depending on scope. Start with a focused MVP to prove ROI – see our MVP guide and cost calculator.

Do I own the AI features you build?

Yes – you own the code and IP. The underlying LLM may be a third-party API, but the integration and product are yours.
