What You'll Receive
Full Description
If you want a smarter, more engaging digital experience for your users, an AI-powered chatbot or web application is one of the highest-impact investments you can make right now. This service delivers exactly that — purpose-built, fully functional AI applications developed by an experienced London-based team with over three years of hands-on AI development expertise.
Whether you need a simple FAQ bot to handle routine customer queries, an article-suggestion engine to keep users engaged, a Q&A assistant trained on your own private documents, or a fully integrated AI web application, this service covers it all. Every solution is built to your specific requirements — not off-the-shelf, not templated.
**What You Can Expect:**
A clean, functional web application with an AI model integrated at its core. The bot can be trained on your own dataset or documents, meaning it answers questions using your content rather than generic internet knowledge. This approach keeps your data private and secure — no sensitive information is passed unnecessarily to third-party services.
The team specialises in ChatGPT and GPT-4 integration, OpenAI API implementation, and Python-based AI development. If you already have an existing chatbot or web application that needs refactoring or upgrading, that is covered too.
**How It Works:**
1. Place your order and share your project details via the order chat.
2. The team reviews your requirements and may ask clarifying questions.
3. Development begins — you receive updates throughout.
4. The completed application is delivered within the agreed timeframe.
5. Revisions are made until you are satisfied.
6. You benefit from 30 days of free post-delivery support.
**Services Included Across Tiers:**
— AI chatbot development using ChatGPT, GPT-4, GPT-3, or OpenAI
— Integration of AI into new or existing websites and mobile applications
— Custom GPT Builder integration (your own trained GPT connected to your site or app)
— Document-trained chatbots for private business data (no third-party sharing)
— Python-based AI solutions and refactoring of existing AI applications
**Who This Is For:**
Business owners who want to automate customer support, SaaS founders needing an intelligent assistant layer, content platforms seeking smarter article discovery, professionals wanting a private document Q&A tool, and developers looking to extend existing apps with AI capabilities.
With unlimited revisions and dedicated post-delivery support included across all tiers, you can move forward with confidence that the final product will meet your expectations.

Frequently Asked Questions
Over 3 years of dedicated experience building AI chatbots and web applications using Python, OpenAI, GPT-3, and GPT-4. Multiple chatbots have been built from scratch across a range of use cases.
Yes. A chatbot can be built that answers questions based entirely on the documents you provide. Crucially, this can be done without passing your content through third-party APIs like OpenAI, keeping your business data secure and private.
Yes — integration into both existing and newly built web and mobile applications is fully supported, regardless of whether the chatbot is new or already developed.
Yes. If you have already trained your own GPT via GPT Builder, it can be integrated directly into your website or mobile app so your users interact with it through your own interface.
Yes. If you have an existing AI or chatbot application built in Python that needs refactoring, optimising, or extending, that work is within scope — particularly on the Standard and Premium tiers.
Providing project details, relevant logins, any existing codebase, and a brief description of what you want the chatbot or application to do is enough to get started. If anything further is needed, you will be contacted via the order chat.
Every order includes 30 days of free support after delivery. If something needs adjusting or a question arises during that period, simply reach out via the order chat.
The Starter tier suits simple chatbots integrated into a single platform. The Standard tier is better for more complex chatbots, multi-platform integration, or document-aware functionality. The Premium tier is for full custom AI web application builds, multi-feature solutions, or projects that also involve refactoring existing code.
