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). Re-read Oct 18, 2026: homepage unchanged in substance (build, update with time-impact analysis, analyze; exports to Primavera P6 and Microsoft Project).

Re-read Oct 22, 2026: homepage unchanged in substance (reads drawings, specs and historic P6 or MSP schedules; builds, updates and analyzes schedules in natural language with CPM logic; exports to Primavera P6 and Microsoft Project; SOC 2 reports on request; says project documents are never used to train shared models); its benefits list structured fragnets for time-impact analysis and update-to-update tracking of float movement and critical-path shifts.

Customer quotes not used.AI project-controls platform where users ask their schedule plain-language questions about what changed, why it matters and what to do next. Vendor says answers are auditable and traceable to source, built on models compatible with P6 principles and 10+ years of scheduling R&D, and offers three modes: hands-on platform tools, on-demand answers, and automated monitoring. Listed functions: continuous schedule-quality scanning (stale logic, broken links), change logging (who changed what, when) with critical-path and milestone impact, ongoing what-if stress tests of the critical path, and role-specific status summaries. Vendor says it is ISO 27001 certified and that customer data never touches public LLMs (vendor claims, not verified). Example prompts include asking which changes since the last update drove the biggest delays on or near the critical path. Re-read Oct 17, 2026: the homepage says schedule versions and key project documents are pulled in and kept in sync through enterprise-grade APIs and integrations without manual uploads, and that a Platform Mode shows how each answer was produced. Re-checked Oct 19, 2026: unchanged in substance (plain-language schedule questions, answers grounded in auditable models compatible with P6 principles, ISO 27001, data kept off public LLMs, Platform Mode, 10+ years of scheduling foundations); the homepage now contrasts itself with generic LLMs and says its answers have no hallucinations (vendor claim, not verified), and still offers free access with a work email. Re-checked Oct 20, 2026: homepage unchanged in substance; its feature pages describe a Delay Navigator that traces a chosen activity back through its predecessors to the start delay, shows the impact on later activities and ranks the suppliers, activities or contractors contributing most delay by activity code (pitched for planners, consultants and gathering evidence for disputes), Change Control with side-by-side critical-path comparisons in an interactive Gantt, and Schedule Integrity with 14 DCMA metrics (the page spells it DMCA) plus 29 proprietary checks and configurable thresholds; the Security FAQ says the platform runs on AWS with logical tenant isolation, default data hosting in the USA, EU, UK and Australia, ISO 27001 and UK Cyber Essentials, and AES-256 encryption at rest (vendor statements). Re-checked Oct 21, 2026: unchanged in substance (plain-language schedule questions with auditable answers, three modes, continuous schedule-quality scanning, change logging, what-if stress tests of the critical path, role-specific summaries, data kept off public LLMs, Delay Navigator tracing a start delay through predecessors); the no-hallucinations line and customer quotes are vendor claims and not used. Re-checked Oct 23, 2026: homepage and feature pages unchanged in substance (three modes; continuous schedule-quality scanning; change logging with critical-path and milestone impact; ongoing what-if stress tests; role-specific summaries; Delay Navigator; Change Control; Schedule Integrity with 14 DCMA metrics and 29 proprietary checks). Feature pages also list Portfolio, Trends, an AI Agent for chatting with project data and AI Reports, and free Education Hub courses including an AI QSRA (quantitative schedule risk analysis) walkthrough. The Security FAQ adds daily encrypted backups replicated to a separate AWS region, role-based least-privilege access with MFA for privileged accounts, and independent penetration testing (vendor statements). Customer quotes and case-study figures are vendor material and not used.

Where the vendor descriptions differ

  • What each does: Karmen says it reads project documents (drawings, specs, and historic schedules and templates in P6, MSP or XER) and, steered in natural language, builds new schedules with CPM logic, updates existing ones and analyzes how a schedule evolves. Nodes & Links lets users ask plain-language questions about a schedule (what changed, why it matters, what to do next) in three modes: hands-on platform tools, on-demand answers and automated monitoring.
  • Delay and change work: Karmen lists structured fragnets for time-impact analysis as scope changes, and update-to-update tracking of float movement and critical-path shifts. Nodes & Links lists change logging (who changed what, and when) with critical-path and milestone impact, continuous schedule-quality scanning for issues such as stale logic and broken links, ongoing what-if stress tests and role-specific summaries; its feature pages (read Oct 20, 2026) describe a Delay Navigator and Schedule Integrity checks built on DCMA metrics.
  • Schedule tools: Karmen exports to Primavera P6 and Microsoft Project. Nodes & Links says schedule versions and key documents are pulled in and kept in sync through APIs and integrations, and that its answers come from models compatible with P6 principles (vendor statement).
  • Security (vendor statements): Karmen shares SOC 2 reports on request, encrypts data in transit and at rest, and says project documents are never used to train shared models. Nodes & Links says it is ISO 27001 certified and that customer data never touches public LLMs.
  • Pricing (checked Oct 23, 2026): neither publishes prices. Karmen's calls to action are Book a demo and Talk to us, and its /pricing page returns not found; Nodes & Links offers Get a Demo and See it on my project, and its /pricing address redirects to the homepage.
  • Not used here: customer quotes and star-rated testimonials on both sites, and Nodes & Links' accuracy claims, are vendor content and not used. We have not tested either tool.

Good or bad, an honest review from an estimator, PM or super helps the next team more than another vendor demo. You post under a handle; your email is never shown.

Questions to ask in your review

  • How close Karmen's generated logic gets to your scheduler's own on the same project
  • Whether Karmen's time-impact fragnets and Nodes & Links' change log point to the same delay drivers
  • What either costs for your project count or schedule size
  • What did you use it for, on what kind of work and project size?
  • How long did setup and training take, and who on your team did it?
  • What does it cost you in practice, compared with what the sales call said?
