Full Description
Your customers expect instant, intelligent answers — and your team deserves to stop answering the same questions repeatedly. This service delivers a bespoke AI chatbot built from the ground up using GPT-4 and leading large language model (LLM) frameworks, so your business can automate conversations, qualify leads, and serve users around the clock without adding headcount.
Whether you need a simple FAQ bot for your blog or small business website, a knowledge-base assistant trained on your own documents, or a fully integrated lead-generation and customer support agent connected to your CRM, there is a tier here built for your scope.
**What is included across all tiers:**
Every chatbot is built to your specific use case — not a generic template dropped onto your page. The entry tier covers a focused, well-crafted AI chatbot handling tasks such as FAQs and content suggestions, ideal for blogs, small business websites, and straightforward web deployments. The Boost tier scales this into a more capable, integrated solution suited to growing businesses that need multi-topic handling, CRM or Google Sheets connectivity, or lead qualification flows. The Premium tier delivers a full-scope AI system — think document-trained RAG pipelines, multi-platform deployment, Zapier or Make automation, and enterprise-grade architecture with Botpress, OpenAI API, or custom GPT builds.
**How the process works:**
After you place your order, share your use case, any existing content or documents, and your platform details via the order chat. The team will review your requirements, confirm the scope, and begin building. You will receive regular updates and have revision rounds included at every tier to ensure the final bot matches your expectations precisely.
**Who this is for:**
This service suits small business owners who want to automate customer queries, bloggers and content sites needing smart article or FAQ bots, startups building AI-powered products, and established businesses looking to integrate intelligent automation into existing CRMs, apps, or websites.
**Why work with this seller:**
Based in London with global project delivery, the team brings 7+ years of combined experience across AI, machine learning, and data science. The technical stack spans Python, GPT-4, LangChain, Botpress, Llama 3, RAG embeddings, TensorFlow, PyTorch, and more — meaning your chatbot is built with the right tool for the job, not whatever is easiest. Integration into existing systems is a core strength, and post-deployment support is part of the relationship, not an afterthought.

Frequently Asked Questions
Share your use case, the platform or system the chatbot will live on (website, app, CRM, etc.), any existing content or documents you want the bot trained on, and your goals — for example, answering FAQs, qualifying leads, or booking appointments. The more context you provide, the faster the build can begin. Further questions will be asked via order chat if needed.
The Starter tier suits blogs, small business websites, and anyone needing a single-purpose bot such as FAQ handling or content suggestions. The Boost tier is ideal for businesses that want lead qualification, CRM connectivity, or richer multi-topic conversations. The Premium tier is designed for complex, document-trained systems deployed across multiple platforms with full automation pipelines.
Yes — integration into existing systems is a core part of this service. Whether you are running a custom website, a mobile application, or a CRM platform, the aim is seamless integration with minimal disruption to your current operations. Please mention your platform and tech stack when placing your order.
Every tier includes 3 revision rounds. A revision covers adjustments to the chatbot's behaviour, tone, conversation flows, or response accuracy based on your feedback after reviewing a delivered version. Entirely new features or a change in the core use case would fall outside the original scope.
Delivery is 7 days for Starter, 14 days for Boost, and 45 days for Premium — reflecting the complexity at each level. If you need the Starter or Boost delivered sooner, the Extra Fast Delivery add-on is available at checkout.
Post-deployment support is part of the relationship. If you encounter issues, need updates, or have questions after receiving your deliverable, you can raise them via the order chat. The team is available to assist with troubleshooting and guidance.
Industry best practices are followed throughout. Any documents, knowledge bases, or business data you share are used solely for building your chatbot and are handled with strict confidentiality. Robust security measures are applied to protect against unauthorised access.
Yes — document-trained chatbots using Retrieval-Augmented Generation (RAG) and embeddings are available in the Premium tier. If this is your primary requirement, select Premium and share your documents after purchase. If you are unsure which tier fits, describe your use case in the order requirements and the team will advise.
