I will integrate chatgpt and ai features into your flutter app
Ayan Parvaiz
About this gig
Adding AI to an app is easy to demo and hard to ship. The first call works.
Then streaming stalls, the bill triples, non-English text breaks, and one
user's chat shows up in another user's session.
I'm Ayan, a Flutter developer and AI engineer, 5+ years and 36+ apps shipped.
I have run an AI assistant app in production for three and a half years in 19
languages, and built a platform where a written prompt becomes real software.
WHAT I BUILD INTO YOUR APP
- Streaming chat, token by token, with cancellation that really cancels
- Multi-model routing across OpenAI, Claude and DeepSeek, with fallback
- Image generation and AI photo features
- Voice input and text-to-speech
- Chat history, folders and search
- Usage limits and credits, so your bill stays predictable
- Prompt design and content moderation
WHY IT HOLDS UP
Every provider sits behind one adapter, so switching models later is a config
change, not a rewrite. Slow calls run through a queue, so the UI never freezes.
You keep your own API keys and your own data, and you get the full source code.
Message me with what you want the AI to do, and I will tell you what it will
realistically cost to run each month before you order

I'm Ayan — a Flutter developer with apps live on the App Store and Play Store. 5+ years, 36+ apps shipped, 100K+ daily users.
I build the app and the backend behind it: Flutter on iOS, Android, web and desktop, Node and NestJS APIs, and AI that survives production. Shipped in healthcare (HIPAA), dental, fintech and education.
My edge is the hardware most Flutter developers avoid — NFC tags, RFID handhelds, vendor SDKs with no Flutter package. When none exists, I write the bridge.
Message me before ordering and I'll say honestly if I'm the right fit.

FAQ
Do I need my own OpenAI API key?
Yes. The keys and the billing stay in your account, so you control the spend and own the data. I'll help you set it up and show you where to monitor usage.
How much will the AI cost me every month?
That depends on your users and which model you pick. Tell me your expected usage and I'll give you a realistic estimate before you order — and I'll build in caching and usage limits so it doesn't run away.
Can you make it work with my existing app?
Yes, that's what this gig is for. Send me your Flutter project and I'll add the AI layer to it. I'll tell you first if anything in the current structure needs changing.
Which AI models can you integrate?
OpenAI (GPT), Claude, DeepSeek, and most providers with a REST API. I build it so the provider can be swapped later without rewriting your app.
Do you do fine-tuning or training custom models?
No. I integrate existing models through their APIs and get excellent results with prompt design and context. If you truly need a fine-tuned model, I'll tell you honestly rather than take the order.
