ISIN Issuance Application Solution with Integrated Virtual AI Assistant
Summary: Our client, a leading stock exchange in the UK, supports companies through the lifecycle of listed securities, including the allocation of International Securities Identification Numbers (ISINs). pTools has supported the client since 2019, when we first built and deployed their ISIN Issuance Application for the exchange.
In early 2025, the client engaged with pTools to take the platform a step further, integrating an AI-powered Virtual Assistant to guide handlers through every step of the ISIN submission process.
The Challenge: The client operates under stringent UK, EU, and global data protection requirements, including GDPR. Any AI solution had to meet an exceptionally high bar:
All data must remain fully secure and never leave the platform
Data must never be used to train external AI models
Responses must be grounded solely in the client's own documentation, eliminating the risk of AI hallucinations
The assistant had to handle unstructured user queries and return clear, structured, contextually relevant answers throughout the submission journey
The Solution: pTools designed and delivered a secure ISIN Virtual AI Assistant, trained exclusively on the client's ISIN documentation, including FAQs and guidance notes.
100% Accuracy: The assistant responds strictly from the defined knowledge corpus, ensuring complete accuracy at every step
Contextual, step-by-step guidance: Embedded across the entire ISIN submission form, the assistant provides real-time support tailored to where the handler is in the process.
pTools Secure API Layer: A purpose-built secure layer between users and the underlying AI model ensures the client's data is never exposed externally or used to train third-party models.
Admin intelligence dashboard: Administrators can review queries, identify gaps, and continuously improve the knowledge base via an intuitive analytics dashboard.
API-first architecture: Delivered via a robust API, seamlessly integrated with the client's existing infrastructure and designed to extend to additional platforms.
The Result: Within the first month of deployment, the client saw a 13% increase in ISIN issuances alongside a significant reduction in submission times, with handlers receiving immediate, accurate assistance at every stage.
The admin team gained a powerful new tool to monitor interactions and keep the knowledge base current. The client is highly satisfied and is already exploring how to extend the AI Assistant to other internal platforms, including their Corporate Announcements Solution.
