LogicReader is a schedule-intelligence platform for engineering and infrastructure projects. Compare revisions, build defensible logic, assess risk, summarise huge programmes, and audit every dependency — on top of the schedules you already produce: Primavera P6 XER files and Excel workbooks, and other tools through their P6 XER export.
Free for as long as you use it and give us feedback — open a schedule, read it, and work on it. We ask for your email so we can send you a confirmation link; nothing is shared. One product, four ways to run it: run it here for free, unlock P6 export, collaboration and bigger projects with LR Plus, or keep it inside your own perimeter with Desktop (offline) or Enterprise. Web access is what is available today; Desktop and Enterprise follow, and you can register your interest — see the four ways in.
Ten things, all on the same canvas. Pick any one as the entry point — the others come along for free.

Most scheduling tools are built for one user — the planner. We work so that the engineer, the project manager, the site lead, the commercial lead, the director and the bid manager all get their answer without going through the planner. Not for a procurement portal. For the engineer who actually has to build the thing.
Pick your role to see what it fixes.
A schedule is not a bar chart. It is the moment a looping process — do, check, redo — agrees to stop: every loop unrolled into a fixed number of passes, priced into the budget, signed by everyone. The logic is what gives the dates their meaning.
Question the logic until you understand it, and it tends to move one of two ways. Some of it needs breaking down further, because one activity is hiding several pieces of work. Some of it can be brought together, because several activities or links are saying the same thing. Either move brings the logic to the right level of detail — and that is what makes an honest summary possible, and what gives you proper control of the WBS, the dependencies and the resources.
LogicReader puts that logic on the canvas — visible, interrogable, defensible — so every stakeholder can see why a date is what it is, and stand behind it.
What makes a schedule clear to a human — this link exists for this reason, decided by this person, at this cost to change — is exactly what makes it computable by a machine. Readable and AI-usable are one property, not a trade-off.
Others teach AI to guess what happened. LogicReader records why it happened — so AI never has to guess. The typed, justified record your team builds every day becomes the ground your own AI, under your control, can stand on.
One principle shapes every product decision. We will trade features for it. We will not trade it for features.
If using LogicReader doesn’t feel better than working in P6, none of the analytics matter. Visual clarity, instant feedback, and graceful behaviour at scale are not features — they are the product.
Data & Trust
Six absolute commitments. No marketing caveats.
Your schedules stay your IP. Export or delete any time.
Behind authentication. TLS in transit. Backed up every night in the UK.
Ever. Not on aggregated data. Not on “anonymised” data.
Not sold, licensed, distributed, syndicated. Period.
No industry reports drawn from your projects. No derived analytics.
Enterprise tier runs entirely in your perimeter. No data leaves.
Where we’re going
CosmosPM is a British company on UK-hosted infrastructure. Our AI provider today is US-based (Anthropic) and used only when you activate an AI feature inside LogicReader — never on stored schedules. As European frontier models (Mistral, Aleph Alpha, and the UK’s emerging AI ecosystem) reach capability parity, LogicReader will offer a UK/EU-sovereign AI option with the same six commitments above carried unchanged. The AI layer is pluggable by design, not hard-wired. No permanent lock-in to US compute. See the sovereignty path →
