Credit where it is due. CDM Wizard is a CITB-backed tool that has done genuinely good work helping smaller builders get to grips with CDM 2015 - it is free, it is straightforward, and for many builders it was the first time they engaged with CDM compliance at all. If you are just starting to learn the regulation, CDM Wizard remains a great starting point. The question is what comes next. Once you understand the basics, you need a tool that actually produces professional, site-specific documents and covers more than just the CPP checklist. That is where The Site Book picks up - building on the foundation CDM Wizard laid, not replacing it.
At-a-glance fit per product - pulled from the same data that drives the snapshot table.

Short, straight answers - the same questions real builders ask.
No. CDM Wizard is a learning-focused tool - it walks you through CDM 2015 as a checklist but does not produce site-ready RAMS, COSHH assessments, or method statements. If you need actual compliance documents for a real project, you still need a separate tool to create them. The Site Book generates all of these from a plain-English job description in a single platform.
Yes, CDM Wizard is free to use. That makes it a reasonable first stop for builders who are brand new to CDM 2015 and want to understand the framework. But free walkthroughs do not produce the documents you hand to workers on site - that is the job The Site Book does, with Pro at GBP39/month or GBP360/year after your free first project.
You could - CDM Wizard for understanding the regulation, The Site Book for producing the documents. But The Site Book's in-app AI chat and document quality checking already explain CDM requirements contextually while you work, so most users skip the separate learning tool once they start. One platform handles both knowledge and output without juggling tabs.
CDM Wizard is best for someone learning the basics of CDM 2015 for the first time. It does not generate documents and is not designed for live project use. The Site Book is the right tool once you need to actually produce a CPP, a RAMS, or a site induction for a real job. Different stages, different tools.
Yes. The Site Book has a free tier that lets you create your first project and generate real documents - your CPP, RAMS, and site induction - without entering a credit card. You see exactly what the platform produces before deciding whether to upgrade. That is a practical next step for anyone who has outgrown the CDM Wizard checklist.
