Sobre este Serviço
Already have an app but need AI chatbot, voice assistant, or smart automation added? Rebuilding from scratch just to add AI is slow, expensive, and unnecessary - that's the technical problem most app owners run into.
The real challenge is integration: connecting AI to your existing backend without breaking current features, matching the new chat or voice UI to your app's current design, and keeping response times fast. I solve this by working directly inside your existing React Native or Flutter codebase.
I connect AI chatbots and voice assistants to your existing Firebase, Supabase, Node.js, or custom backend using OpenAI, Claude, Vapi, or Retell APIs, plus Twilio and n8n for automation - no rebuild, no new app, no lost development time.
What you get: context-aware AI chatbot with chat history, natural AI voice assistant that sounds human, smart automation workflows, secure API key handling, and full testing across iOS and Android before delivery. Your codebase, UI, and backend stay exactly as they are, just smarter.
Message me your app details and current tech stack before ordering so I can confirm scope, cost, and give you an accurate delivery timeline.

Perguntas frequentes
Which AI tools and APIs do you work with?
I integrate OpenAI, Claude, Vapi, and Retell for chat and voice, plus Twilio for calls and n8n for automation, connected to your Firebase, Supabase, Node.js, or custom backend.
What do you need from me to get started?
Access to your app's repository (GitHub, GitLab, or zip), API keys or accounts for your chosen AI provider, and a quick note on where you want the chatbot or voice feature to appear.
How long does delivery take?
Basic chatbot integration typically takes 3–5 days. Voice assistant and full automation builds take 7–10 days depending on your app's complexity and current backend setup.
Do I need to rebuild my app to add AI features?
No. I work directly inside your existing React Native or Flutter codebase, so your app keeps its current UI, navigation, and backend. No rebuild, no new app version needed.
Will the AI feature match my app's current design?
Yes. I build the chat or voice interface to match your existing UI, colors, and navigation so it feels like a native part of your app, not a bolted on add on.
