    Regulatory reporting without the risk: 1,000+ pages of guidance, reports in under two hours

    A mid-sized regulated business was spending three to four days of skilled compliance time on every reporting cycle. Pro AI built a custom retrieval system with a code-based validation layer that catches errors before they reach a report. Six to eight weeks from audit to go-live; zero compliance errors since.

    The problem

    The compliance team was drowning in documentation. Every reporting cycle meant manually searching more than a thousand pages of regulatory guidance, cross-referencing several governance frameworks, and hand-building reports to the formats their regulator and their board expected. It took three to four days of skilled time each cycle, results varied depending on who did the work, and the risk was real: a missed clause or a misread guideline could mean a breach. The business needed to scale its reporting without scaling its headcount.

    Why not just use ChatGPT?

    It was the first question, and a fair one. A general-purpose model doesn't know this client's guidance, will confidently invent a clause when it can't find one, keeps no record of where a statement came from, and can't be pointed at a regulator. For work where being wrong is a breach, a chatbot is the wrong tool. What the team needed was a system that knew their documents, could show its working, and would refuse to say anything it couldn't back up.

    What we built

    A custom retrieval-augmented generation (RAG) system designed around the client's own regulatory corpus:

    • Ingests and indexes the full regulatory document library, and re-indexes as guidance changes — so the system is current on the day new guidance is published.
    • Retrieves the relevant sections for each report and drafts to the client's existing templates, so outputs drop straight into their internal and external submission formats.
    • Passes every statement through a validation layer written in plain code, sitting between the language model and the output. Each claim is checked against the source guidance; anything that can't be traced back is removed before a person sees it. This is what eliminated hallucinations in practice rather than in theory.
    • Runs at the same cost whether it produces ten reports or a hundred — the architecture handles ten times the previous volume with no additional resource.

    The language model is interchangeable: the system was built model-agnostic, so the underlying AI can be swapped as better or cheaper models arrive without rebuilding the validation logic that makes it trustworthy.

    How it was delivered

    The engagement started with an Automation Audit — a workshop with the compliance team and a written map of where their time went. The reporting cycle was the obvious first target. Build, testing against past reporting cycles, and go-live took six to eight weeks, with the team reviewing outputs side-by-side with their manual reports until they were satisfied nothing was being missed. Only then did the system take over.

    The impact

    What consumed three to four days of skilled compliance resource per cycle now completes in under two hours. The team has reclaimed the equivalent of one and a half full-time roles and redirected that capacity into advisory and strategic work. With zero errors recorded since deployment, regulatory risk has been removed from the reporting process, and the business can now respond to new guidance the same day it's published.

    Is this your problem too?

    If your business produces reports, submissions or documents from a large body of rules — regulatory guidance, standards, contracts, policies — the same pattern applies. The audit is how we find out whether it will pay back for you.
