What it doesAI scheduling co-pilot, steered in natural language, that reads project documents to build new schedules, update existing ones and analyze changes. It reads drawings, specs, historic schedules and templates in P6/MSP/XER; new schedules include WBS, activities and logic links; updates include time-impact analysis (fragnets); and analysis tracks float and critical-path movement between monthly updates. Exports to Primavera P6 and Microsoft Project. Vendor says it learns from your historic schedules and reads thousands of pages in minutes (vendor claims, not verified). Security: vendor says SOC 2 reports are shared on request, data is encrypted in transit and at rest, and project documents are never used to train shared models. Re-read Oct 17, 2026: consistent with the above; the page lists three jobs (build new schedules, update existing ones with time-impact analysis, analyze schedule evolution over time).

Customer quotes are not used.AI for project controls trained on a dataset the vendor says contains 750,000+ historical schedules (over $2Tn of construction spend). Four use cases: Plan (generate schedules from scope documents, check schedule integrity), Assure (activity-level uncertainty forecasts), De-risk (flag risky activities and check them against your risk register), and Deliver (project and portfolio summaries). Products: Portfolio, Insights, Schedule Studio, and Schedule Integrity Checker; vendor says Schedule Studio connects to Claude and ChatGPT and exports XER. Works with existing schedules. Sectors listed include highways, rail, and heavy infrastructure. Re-read Oct 17, 2026: the homepage also points to a Model Performance 101 white paper that frames forecast accuracy as mean absolute error (MAE), which it says falls as more schedules become available, and offers user training courses with certifications. Re-checked Oct 19, 2026: the homepage now also lists Decision Intelligence (route options when a project reaches a crossroads) and Insights Risk Professional, cites $500bn of projects under active management (vendor claim), mentions a Driving Paths view in Schedule Studio, and offers nPlan Academy courses of about two hours with certifications. Its featured white paper is now AI-First Project Controls and Delivery; the Model Performance 101 paper we noted Oct 17 is no longer linked on the homepage. Re-checked Oct 20, 2026: homepage unchanged in substance (750,000+ schedules and over $2Tn of spend, the four use cases, $500bn under active management, nPlan Academy courses of about two hours); the product menu lists Insights Pro, Insights Core, Insights Contract Risk, Insights Risk Professional, Insights Project Management Professional, Portfolio, Schedule Integrity Checker, Schedule Studio and Decision Intelligence, and a featured blog post describes Schedule Studio's link to Claude and ChatGPT for questions, edits, health checks and XER export (vendor statements). Re-checked Oct 21, 2026: unchanged in substance (750,000+ historical schedules, the four use cases, Schedule Studio's link to Claude and ChatGPT with XER export, nPlan Academy courses of about two hours); the homepage now lists Project Controls Expo Australia 2026 at the Melbourne Cricket Ground among its events and a blog recap of its AI Day mentioning a Decision Intelligence demo and an orchestration engine it calls Khaleesi (vendor statements). Re-checked Oct 22, 2026: unchanged in substance; the site lists upcoming events at Wembley Stadium, London (Nov 2, 2026) and the Melbourne Cricket Ground (Nov 23, 2026). Re-checked Oct 23, 2026: homepage unchanged in substance (schedule risk forecasting trained on 750,000 past project schedules, Decision Intelligence, a schedule assistant that works with Claude and ChatGPT, nPlan Academy); events now list Project Controls Expo UK (Nov 2, 2026) and Australia (Nov 23, 2026). Spend and portfolio figures remain vendor claims not used here. Re-checked Oct 25, 2026: a blog item on the site says Schedule Studio now connects to Claude and ChatGPT, so you can ask questions about a schedule, edit it, run health checks and export XER from those assistants (vendor description). Events listed: Project Controls Expo UK (Nov 2, 2026) and Australia (Nov 23, 2026). Schedule-count and project-value figures on the homepage are vendor claims and not used here.

Where the vendor descriptions differ

  • What each does: Karmen says it reads drawings, specs and historic P6 or MSP schedules and templates, then builds new schedules (WBS, activities, logic links), updates existing ones with time-impact analysis (fragnets) and tracks float and critical-path movement between updates, steered in natural language. nPlan describes AI for project controls across four use cases: Plan (generate schedules from scope documents, check integrity), Assure (activity-level uncertainty forecasts), De-risk (flag risky activities against your risk register) and Deliver (project and portfolio summaries).
  • Schedule building: both now offer it. Karmen exports straight to Primavera P6 and Microsoft Project. nPlan says Schedule Studio connects to Claude and ChatGPT and exports XER, and its homepage now says the Schedule Integrity Checker is part of Schedule Studio.
  • Forecasting and portfolio: nPlan's core pitch is forecasting from historical schedules, with Portfolio, Insights products and Decision Intelligence; its sectors list includes highways, rail, heavy infrastructure and, now, data centers. Karmen's pages focus on the scheduler's build, update and analysis work on a single project rather than portfolio risk.
  • Security: Karmen says SOC 2 reports are shared on request, data is encrypted in transit and at rest, and project documents are never used to train shared models. Check nPlan's data-use terms directly, since its forecasts rely on a pooled historical dataset.
  • Pricing: neither publishes prices. Karmen offers Book a demo (/pricing returns a not-found page); nPlan is quote-only.
  • Not used here: nPlan's dataset size, spend and projects-under-management figures; Karmen's speed claims and customer quotes (vendor figures).
