Mortgage regulations your AI can actually read

4,359 regulator-published registers, in the regulator’s exact words, split into sections an AI can read in one pass, each with its citation, version and effective date. Use them in the AI your team already has, in your own software, or entirely inside your own environment.

Regulatory updates using AI Chat and AI Projects

A guide to using AI to update your Policies and Procedures — when to use a Chat and when to use a Project. Chat mode handles one regulatory update against one P&P; Project mode handles a regulation that reaches several P&Ps at once. Same goal, picked by scale. Every regulatory update below is sorted into the way it’s best run, in calendar order.

Is it really that easy? Yes and no. AI and large language models have hallucination problems, so the prompting and the regulatory files have to be built to guard against them. The machine-readable regulatory updates here carry tracking that ties every requirement to its verbatim source, so the AI’s work is checkable instead of trusted — the same anti-hallucination discipline behind every kit. If you have Codex, Cowork, or Claude Code, copy the methodology in, build a few of your own regulatory files, and have some learning-type fun. How we address hallucination in regulatory updates →

Compliance is everyone’s job, including Claude.

Claude is a tool that can increase accuracy and efficiency when the tool is used correctly. Learning more about Claude is win/win as you will understand how operations may be using Claude, and also how Claude can be used to facilitate compliance.

Claude for Compliance gives you mortgage compliance regulations saved as Claude files, so you can bring compliance work into your own Claude projects. Everything stays inside your company’s confidentiality protections.

If your journey looks like mine, you’ll start by using the Claude regulatory files to audit your P&Ps. Once you get started, it’s hard to stop, and the more you use Claude, the better your Claude/AI compliance program will be.

Here’s the whole idea, in four steps:

Those downloads are .md files — plain text (Markdown) that opens in Notepad and pastes straight into any AI chat. Nothing to install, nothing executable, just text you can read and edit.

These regulatory files aren’t just text. Each one carries tracking that ties every requirement to its verbatim source, so the AI’s work is checkable instead of trusted, the same anti-hallucination discipline behind every kit. And several of these rules are already in effect, so this isn’t hypothetical: it’s a chance to check your status and double-check your work against what’s already on the books.

C4C Guardrails: use Claude’s compliance tracking, and check it

Claude Compliance API is a must-use tool. It is the foundational audit record available. Claude Compliance API logs tool calls, and there is a full transcript available. You can set up additional tools in Claude to have Claude notate regulatory applicable workflow and actions in Claude, to understand what is happening, and be able to better answer regulatory questions.

Our why

The more compliance professionals use AI, the better compliance will be with AI. Compliance teams are the ones who think about what happens when things go wrong, and every AI use case a firm wants to deploy needs that careful, cited, documented thinking done first. Claude for Compliance is built so compliance teams can do that thinking at the speed the firm needs, without giving up the rigor that makes the thinking worth doing. More on why →
