I will integrate chatgpt or claude API into your web or mobile app


About this gig
Hello & welcome to my gig!
I'm a software developer with over a decade of experience on Fiverr, specializing in designing and developing custom web and mobile software solutions.
I integrate ChatGPT, Claude, or Gemini into your existing web or mobile app adding real AI capabilities like conversational chat, content generation, smart search, or RAG-based Q&A trained on your own business documents and data.
What you get:
- AI feature integration into your existing app
- Optional database connectivity
- RAG setup so the AI answers using your actual business data
- Model fine-tuning for more accurate, on-brand responses
- Clean, documented code (Premium)
How it works:
Share your app and the AI feature you want added. I'll scope the integration, connect the right AI model and data sources, and test thoroughly before delivery so it works reliably in production, not just as a demo.
With a full-stack background (PHP, Laravel, Node.js, React, Next.js), I build AI integrations that are secure, scalable, and production-ready.
Message me your requirements and I'll recommend the right package.
Regards,
Umar

FAQ
What kinds of apps can you integrate AI into?
Any existing web or mobile app — regardless of what it's built with, I can add AI features like chat, search, content generation, or automated responses.
What is RAG, and do I need it?
RAG lets the AI answer questions using your actual business documents or data, rather than generic knowledge. If you want the AI to know your specific content (product info, support docs, internal data), RAG is the right approach — available in Standard and Premium.
Do I need to give you access to my existing codebase?
Yes, I'll need access (or a clear handoff process) to your existing app to integrate the AI feature properly and test it in context.
Which AI model should I choose — GPT, Claude, or Gemini?
It depends on your use case, budget, and data sensitivity. Message me your requirements and I'll recommend the best fit.
What does "model fine-tuning" mean?
It means adjusting how the AI responds so it matches your brand voice and gives more accurate, relevant answers for your specific use case — included in the Premium package.
Will I own the code?
Source code is included in the Premium package. Basic and Standard include a fully working integration without separate source code delivery.
How long does this take?
Basic: 4 days, Standard: 7 days, Premium: 12 days, depending on complexity and how much data needs to be processed for RAG.
Can you build this from scratch instead of integrating into an existing app?
Yes — if you don't have an existing app yet, message me and I can scope a custom build instead.
