Online XER Viewer
Open and print any XER, no P6 needed. Read a Primavera P6 .xer as a clean Gantt: WBS, dates, float and critical path. Filter, find, and print to PDF. Nothing is uploaded.
Primavera P6 tools
Browser-based tools for P6 schedules.
A small, growing toolkit we build for our own programme work and share. Everything runs entirely in your browser, your files are never uploaded and never leave your device. No account, no sign-up.

Beginner-friendly, no Primavera licence needed, no jargon.
Schedule Mentor
A friendly review that teaches you what to fix, not an audit. It explains what to change, why it matters and exactly how to do it in P6, using examples from your own file. Nobody sees it but you.
Schedule quality & analysis
Check and interrogate how the schedule is built.
XER Path Analyser
Trace all activities between any two activities, find orphaned activities, and visualise how a path interacts with the critical path, straight from a P6 .xer export.
DCMA 14-Point Assessment
Run the 14-point schedule health check on a P6 .xer with fully adjustable RAG thresholds, a colour-blind-safe dashboard, drill-down detail, and a print-ready assurance report. Save agreed threshold profiles to disk.
Schedule Risk Analysis (QSRA-lite)
Monte Carlo risk analysis of your P6 network, in the browser: see what confidence level your plan date really deserves and which activities drive the risk. Screening grade, with an honest validation gate. Nothing is uploaded.
Reporting & progress
Communicate status, slippage and location.
Schedule Comparison & Milestone Slip
Compare baseline, current and interim P6 schedules: milestone slip tables by class, the classic slip/trend chart, a full change register, float erosion, and a draft factual narrative (with an optional in-browser AI model).
Time–Chainage Chart
Turn a P6 schedule of linear works, rail, highways, pipelines, tunnels, into an interactive time–location diagram. Map chainage from UDFs, codes or the activity ID, then export to PNG/SVG, PDF and Excel. Nothing is uploaded.
Contractor Progress Roll-Up
Roll a detailed contractor L3/4 programme up onto your summary L2. Map each activity to a date span, derive percent complete, actual start and a calendar-corrected remaining duration, review every change, then export an updated XER. Nothing is uploaded.
File utilities
Clean up and convert Primavera P6 files.
XER Anonymiser
Strip or pseudonymise names, resources, costs and notes from a P6 .xer, keeping the logic, dates, durations and float, so you can share a real programme’s structure without the sensitive content. For nuclear, defence and commercially sensitive work. Nothing is uploaded.
MS Project XML Importer & Fixer
Repair the defects that make a Microsoft Project XML (MSPDI) file fail Primavera P6’s import, blank rows, duplicate UIDs, bad calendars, external links, and get a fixed XML, an experimental XER, and a PDF change report. Nothing is uploaded.

Commercial & claims
Build events and notices from programme evidence.
EWN & Compensation Event Assistant
Compare the accepted baseline against the current programme, attribute where it has grown in time, scope or cost, and draft NEC Early Warning Notices and Compensation Event notifications from your own attribution. It detects, structures and drafts, it never decides what is claimable, and costs read from a programme are planning data, not a priced quotation. Nothing is uploaded.
