What You'll Receive
Full Description
Stop making your team wade through hundreds of pages of documentation, manuals or reports. This service delivers a production-ready, AI-powered question-answering web application built specifically around your own documents — so anyone can ask a plain-English question and receive an accurate, contextual answer in seconds.
Powered by OpenAI's GPT-4 or GPT-3.5 Turbo, Pinecone vector storage and the Langchain orchestration framework, the application ingests your documents, indexes them semantically, and wraps the whole thing in a clean, mobile-responsive chat interface. The result is a bespoke knowledge-base chatbot that works exclusively with your content — not generic internet data.
**What is included in every package:**
- Custom AI chatbot web application tailored to your documents
- Support for PDF, TXT, CSV and Markdown file formats
- Semantic search and retrieval powered by Pinecone vector database
- OpenAI LLM integration (GPT-4 or GPT-3.5 Turbo)
- Langchain orchestration for accurate, contextual responses
- Mobile-responsive front-end design
- Deployment-ready application (you supply your own API keys)
**How it works:**
1. After placing your order, share your documents (PDF, TXT, CSV or Markdown) and your OpenAI and Pinecone API credentials via the secure order chat.
2. The application is built and configured to your document set, with the vector index populated and tested.
3. You receive the deployed, working web application ready for your users — with revisions included should anything need adjusting.
**What you will need to have ready:**
- Your documents in PDF, TXT, CSV or Markdown format
- An OpenAI API key (generated from your own OpenAI account)
- A Pinecone API key, environment name and index name (available from your Pinecone account)
**Who is this for?**
This service is ideal for businesses, teams and professionals who hold large volumes of documentation — compliance manuals, product catalogues, legal documents, internal knowledge bases, training materials, research reports — and need a fast, intelligent way to query that information without reading every page.
Whether you are building an internal tool for your operations team or a customer-facing assistant for your website, Zinn Digital brings the technical expertise to deliver a polished, reliable application built around your exact requirements. If you have a specific or custom request beyond the standard scope, raise it in the order chat and it will be assessed before work begins.

Frequently Asked Questions
No deep technical knowledge is required to use the finished chatbot. You will need to supply your own OpenAI and Pinecone API keys, which are straightforward to obtain from each platform's dashboard. Once the application is deployed, end users simply type questions into the chat interface.
The application supports PDF, TXT, CSV and Markdown (.md) files. If your documents are in a different format, please raise this in the order chat before work begins so the scope can be assessed.
The Starter package does not include source code. If source code is important to your project, please get in touch via the order chat to discuss whether this can be accommodated and at what additional scope.
The Boost and Premium packages are designed to accommodate larger and more complex document sets. If you are unsure which tier fits your volume, describe your requirements in the order chat after purchase and the scope will be clarified before work begins.
Yes. The application uses your own OpenAI and Pinecone API keys, so any usage costs are billed directly to your accounts by those providers. These costs are entirely separate from this service and depend on your usage volume.
Revisions cover adjustments to the delivered application — such as changes to the chat interface, document re-ingestion if you supply updated files, or configuration tweaks — within the original agreed scope. Revisions do not cover adding entirely new features outside the original brief.
Everything is exchanged through the encrypted order chat on the platform. Please do not share credentials anywhere other than the secure order messaging system.
The deliverable is a standalone web application. If you require embedding into an existing site, please raise this in the order chat before work begins so it can be scoped appropriately.
