Reading & free previews
Anyone can read the blog, browse the public map, and explore the whole Equipment Hub for free. Across the rest of the archive you can open a set number of items per section before subscribing:
PRN Access (£2.99/mo) and every higher plan unlock all of it, with no limits.
Investigation tools
The AI Analysis Lab, R&D Lab and Case Builder are for members — any paid plan gets full access. Every new free account gets a one-time 10-token taster to try the AI Analysis Lab; the R&D Lab and Case Builder need an active plan.
AI research tokens
Monthly allowances: Researcher / Investigator 150, Team 500, Team Member 100. PRN Access has no monthly allowance but can buy top-ups. Your allowance refreshes on each renewal.
Token top-up packs
Need more? One-time packs of 250, 750 or 2,000 tokens. Top-up tokens are additive and do not reset on renewal. An active membership is required to buy them.
Teams & seats
A PRN Team owner manages the team and member seats. Each team member pays their own £3.99 Team Member seat and joins via the team's invite link or PIN — the owner is not billed for members' seats.
Billing & cancelling
All prices are in GBP and renew monthly. Cancel any time from the billing portal — your access continues until the end of the paid period, then drops back to the free preview.
Always free — no account needed. The blog, the interactive Map, the entire Equipment Hub, and all safety, ethics and public-interest guidance are never paywalled — plus a set number of free items in every content section. Membership unlocks the rest of the archive and the investigation tools.
