The Site Book vs RAMS AI — UK CDM Compliance Compared
RAMS AI generates RAMS, CPPs, COSHH and inductions on pay-as-you-go credits from GBP29.97 per 300, with a Professional plan at GBP39.97/mo - a good fit for contractors who issue documents irregularly. The Site Book, at GBP39/mo or GBP360/yr flat, pairs the generated CDM pack with site operations: per-worker sign-off, attendance, certificate tracking and a one-click audit pack. Choose credits for occasional paperwork; choose The Site Book to run live sites week to week.
RAMS AI's pay-as-you-go credits suit contractors who issue documents irregularly; The Site Book wins when a builder needs the full CDM pack plus site operations, worker sign-off, and an audit pack on flat pricing.

Sweet spot
A principal contractor on a domestic or small commercial project who needs ready-to-sign CDM documents, worker sign-off, a live people-on-site view, practical site files, subcontractor evidence records and lightweight inspections/actions.
Strengths
UK construction compliance tool that ships RAMS + CPP + COSHH + inductions (readable and acknowledgeable in 9 worker languages, with the language audit-recorded) + worker sign-off plus Business site attendance, portal users, site files, document reviews, subcontractor evidence and inspections/actions.
AI-generated documents are site-specific from a natural-language brief, not a template library you hand-fill - cuts writing a RAMS from 2 hours to under 5 minutes.
Worker sign-off, PCPP import, cert tracking, and document checking sit on the £39/month Pro plan, not locked behind an enterprise contract.
Transparent pricing: Starter £0, Pro £39/month or £360/year, Business £199/month with 5 internal team logins and 25 active site portal users.
Build RAMS for any trade - add your own work types and method statements alongside the built-in library, reusable across projects, including a ready-made Commercial Solar PV group.
COSHH goes deep: a standalone COSHH assessment document, upload-a-Safety-Data-Sheet extraction, a site-specific substance register and an expert-reviewed library - plus per-worker RAMS sign-off and a one-click Audit Pack that merges every compliance record into one PDF.
Weaknesses
New product (launched 2025) -smaller customer base and shorter track record than established tools like HandsHQ.
No Procore / Autodesk Construction Cloud integrations yet -compliance docs live inside The Site Book and export as PDFs rather than syncing into a wider PM stack.
Site files are a practical portal for drawings, plans and procedures, not formal drawing revision control.
UK-focused content (CDM 2015, HSE guidance) -international contractors on non-UK projects would need to adapt the output.

Sweet spot
A contractor issuing RAMS irregularly who prefers pay-as-you-go credits over a fixed subscription, and wants a consistency check plus permit suggestions on top of the generated draft.
Strengths
Pay-as-you-go credit model (£29.97 per 300 credits standalone, £24.97 as a Professional top-up; ~£0.08–£0.10 per document activation) means no monthly commitment — unusual in a market of monthly-only subscriptions.
Broad AI document set beyond RAMS: CPP, COSHH, lifting plans (LOLER-aligned), site inductions, toolbox talks with digital attendance, and RIDDOR-aligned incident reporting.
AI consistency checker plus smart permit suggestions (hot works, confined space) add a review layer on top of the generated draft.
First three sample document activations are free, and building/previewing is always free — credits are only spent on activation, lowering trial friction.
Weaknesses
Very new vendor — United Applications Ltd was only registered in 2025 (Companies House 16955835), so there is little independent review evidence or track record yet.
No worker certificate / CSCS tracking, site inspections, or RFI workflow — it is a document generator, not a site-operations or workforce-management platform.
Permits are AI suggestions rather than a full permit-to-work issue-and-approve workflow.
Short, straight answers - the same questions real builders ask.
Is RAMS AI cheaper than The Site Book?
It depends on how often you issue documents. RAMS AI uses pay-as-you-go credits from GBP29.97 per 300, with a Professional plan at GBP39.97 per month. If you write documents only occasionally, credits can cost less. The Site Book charges flat pricing from GBP39 per month or GBP360 per year, but bundles the whole CDM pack and site operations into that fee.
Who should choose RAMS AI?
Choose RAMS AI if you produce Risk Assessments and Method Statements irregularly and prefer buying credits over a monthly commitment. Its pay-as-you-go model, broad AI document set covering CPP, COSHH, inductions and toolbox talks, plus a consistency checker and permit suggestions, genuinely suit occasional users. The Site Book fits better when the same project also needs worker sign-off, attendance and an audit pack.
Does RAMS AI include site inductions and worker sign-off?
RAMS AI generates site induction documents covering nine mandatory sections, which is useful. It does not, however, publicly offer worker certificate tracking, site attendance, or a live people-on-site view. The Site Book lets workers sign inductions and RAMS from their phone, tracks certificates and right-to-work evidence, records attendance, and merges everything into one audit-ready pack for inspectors.
Can RAMS AI replace The Site Book for CDM projects?
Only if generating documents is all you need. RAMS AI is a strong document generator, producing RAMS, CPPs, COSHH and inductions with a consistency checker. For most CDM projects a principal contractor also needs worker sign-off records, certificate tracking, site attendance, subcontractor evidence and an audit pack. The Site Book is built as that wider compliance workspace, not just a document generator.
How do the pricing models actually differ?
RAMS AI foregrounds pay-as-you-go: credits from GBP29.97 per 300 (GBP24.97 as a Professional top-up), roughly a few pence per document activation, with the first three sample activations free and building always free. The Site Book uses flat subscriptions from GBP39 per month or GBP360 per year, up to Business at GBP199 per month. Credits reward low volume; a flat fee rewards steady, everyday compliance work across a project.
