What You'll Receive
Full Description
If your business needs a smarter digital presence — whether that is a conversational AI chatbot, a fully functional mobile app, or a website powered by artificial intelligence — this service delivers exactly that, built to your requirements by an experienced AI development team based in London, England.
Zinn Digital™ specialises in custom AI development across chatbots, mobile applications and web platforms. Every solution is built from the ground up to your brief, not from a generic template, and handed over with clean, well-documented source code so you remain in complete control of what you own.
**What you get with every tier:**
At the foundation, you receive AI model integration into an existing application, chatbot functionality, user authentication, and full source code delivery. Every package includes unlimited revisions and post-delivery support, so you are never left stranded after handover.
**The Standard tier** adds a fully functional iOS and Android application alongside application and website design — ideal if you are launching a new product rather than simply enhancing an existing one. Cross-platform development using Flutter or React Native ensures a consistent, polished experience on every device.
**The Full Build tier** goes further still, incorporating AI model fine-tuning so the intelligence at the core of your product is optimised specifically for your use case, domain and audience — not just a generic off-the-shelf model plugged in.
**Technologies used include:** OpenAI GPT, Dialogflow, Rasa, custom NLP models, Flutter, React Native, multilingual NLP frameworks and translation APIs, payment gateway integration, backend API development, and voice assistant modules.
**Who this is for:**
This service suits founders building their first AI-powered product, established businesses adding conversational AI to an existing platform, and teams who need a technical partner with full-stack AI capability. Whether you need a customer service chatbot, a recommendation engine, a voice-enabled assistant or a complete mobile application with AI at its core, this listing covers it.
**How it works:**
1. Place your order and share your project details via the order chat.
2. Zinn Digital™ reviews your requirements and confirms the scope.
3. Development begins, with regular updates via order messages.
4. Delivery with source code, documentation and setup guidance.
5. Revisions carried out until you are satisfied.
Deployment assistance is available — including Google Play Store upload, App Store submission support and live server deployment — simply raise it in the order chat.

Fine-tuning adapts the underlying AI model to your specific domain, vocabulary and use case rather than relying on a generic pre-trained model. This produces more accurate, relevant and on-brand responses for your users and is included exclusively in the Full Build tier.
All tiers include unlimited revisions. Once a deliverable is shared, simply raise any changes via the order chat and they will be addressed. The goal is to ensure you are fully satisfied before the order is marked complete.
