LogicReader

The logic behind every schedule, visible.

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 Primavera P6, MS Project, or Asta schedules you already produce.

Built by CosmosPM Ltd · UK · private early-access platform

Try LogicReader free — UK-hosted, built for sample and anonymised schedules, with AI features powered by Anthropic (US). All schedule calculations are deterministic; AI is optional, off by default, and can run on your own account or key.

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, three 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 the desktop and on-premise delivery. Web access is what is available today; the desktop build follows — see the three ways in.

What it does

Ten things, all on the same canvas. Pick any one as the entry point — the others come along for free.

Click a box to see it work.

Built for the seven people who live with a schedule.

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.

Why the logic comes first

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.

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.

Honest screenshots

Three capabilities live on the platform right now. No mock-ups.

WHERE THIS MEETS AI

One record. Two readers.

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.

The product promise

One principle shapes every product decision. We will trade features for it. We will not trade it for features.

The interface comes first.

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

Your data is yours. Full stop.

Six absolute commitments. No marketing caveats.

✓ You own it

Your schedules stay your IP. Export or delete any time.

✓ UK-hosted

Behind authentication. TLS in transit. Encryption at rest.

✗ No AI training

Ever. Not on aggregated data. Not on “anonymised” data.

✗ No sharing

Not sold, licensed, distributed, syndicated. Period.

✗ No benchmarking

No industry reports drawn from your projects. No derived analytics.

✓ Inside-firewall

Enterprise tier runs entirely in your perimeter. No data leaves.

Where we’re going

UK-rooted today. Building toward an EU/UK-sovereign, AI-enhanced scheduling stack.

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 →
