LogicReader

Frequently asked questions

Honest answers to the questions we get asked most. If yours isn't here, email us.

Product

Is LogicReader a replacement for Primavera P6?

No, and the distinction matters. LogicReader does two things:

  1. Reads your P6 / MSP / Asta schedule and makes the logic inside it legible — for review, compare, isolate, meetings. The dates you defend to your client come from your scheduling tool, not LogicReader.
  2. Has its own internal CPM engine for exploration — what-if scenarios, logic validation, scratch programmes during a workshop. Useful for thinking, not for contracts. It runs CPM on a continuous-day axis; it doesn't do resource levelling, multi-calendar arithmetic, or the constraint handling your contract needs.

Rule of thumb: use LogicReader to understand what your P6 schedule is saying. Use P6 (or MSP, Asta) for the dates and resources that go in the contract.

Can I use it on a real project today?

Yes — the early-access toolkit imports XER and CSV, computes critical path, lets you compare revisions, isolate scopes, and export to GraphML for yEd. That's a real workflow you can run on your own schedule today.

How big a schedule can it handle?

Smoothly to ~25,000 activities on a modest laptop. Up to 50,000 with a small first-load pause. Above that, expect to need a discrete GPU or to load by sub-programme.

What does it cost?

Today: nothing for the early-access participants. We are not taking payments yet because there isn't a sellable artefact at scale yet. Pricing during pilot is per-project, per-month, agreed individually. The Pricing page sketches the intended commercial model.

Is there a free trial?

Effectively yes — join the early-access list and we'll send you credentials for the live demo. The demo lets you load your own schedule and try every feature. There's no credit card and no time bomb.

Data and security

Where is my schedule data stored?

The live demo runs on a single server in Europe. Your schedule data is held on that one server. It is not replicated, not used for training any model, and not shared. With the planned desktop version, your file stays on your own machine and never crosses the network.

Are you GDPR-compliant?

Yes. CosmosPM Ltd is registered with the UK Information Commissioner's Office (ICO C1928514). Our Privacy Policy describes what we collect and why. Data Processing Addenda are in place with each of our sub-processors (Hostinger, Microsoft, Anthropic, Google).

Do you use my data to train AI models?

No. The AI features we have or plan are read-only assistants — they help you understand your schedule. Nothing you load is used to train or fine-tune a model. The AI vendors we use (currently Anthropic) are bound by contract to the same.

Can I install LogicReader behind our corporate firewall?

Yes — for enterprise pilots we offer an on-premise option inside your own perimeter. Pilots usually start on the hosted demo, then move on-premise before any production schedule data is loaded. Talk to us about your environment.

Compatibility

Which versions of P6 are supported?

XER from P6 7.0 (2010) onwards. Older XERs may parse but are not supported.

Microsoft Project? Asta? Open Plan?

The CSV path covers any tool that can export tabular data, so you can bring MSP, Asta and others in today. Native connectors follow real demand — if you need one, ask us.

Does it run on Mac?

Yes — the web app runs in any modern browser, Mac included. A desktop version is planned for Mac, Windows and Linux.

Company

Who is behind CosmosPM?

Evangelos Kourentzis — chartered mechanical engineer, twenty-seven years in UK infrastructure, P6 specialist, founder of CosmosPM Ltd. Currently building the product hands-on, with input from a small group of pilot users.

Are you funded?

CosmosPM is self-funded today and built deliberately with a small group of pilot users. We're a small company and say so plainly.

Will the product still be here in three years?

Honest answer: that depends on whether enough projects choose it for it to stand on its own commercially — which is true of any small product. Two things hedge the question. One: a desktop version you keep means a worst-case scenario still leaves you with a usable copy. Two: every export is in open formats (GraphML, CSV) so your data is never trapped.
