The free INCOSE GtWR v4 compliant workbench that analyses every requirement against all 42 rules, improves quality with AI, and exports to DOORS — all inside your browser.
Built on International Standards
Studies consistently show that 40-50% of defects originate in requirements. Vague language, passive voice, untestable statements, and missing traceability propagate through design, build, and test — compounding cost at every stage. Most teams catch these issues too late, or not at all.
Every requirement is analysed in real-time against all 42 rules from the INCOSE Guide to Writing Requirements v4. Instant feedback on accuracy, concision, ambiguity, singularity, completeness, and more.
Real-time analysisOne click transforms vague, passive, untestable requirements into INCOSE-compliant statements. Fixes passive voice, vague terms, escape clauses, superfluous infinitives, absolutes, and abbreviations automatically.
Automated rewritingExport your complete requirement set as OMG ReqIF XML — fully compatible with IBM DOORS, DOORS Next Generation, and any ReqIF-compliant tool. Also supports CSV and JSON export.
Industry compatibleVisualise parent-child relationships across four requirement levels: Stakeholder Need → System → Subsystem → Component. Automatically detects orphan requirements missing upward traces.
4-level hierarchyVerification method distribution dashboard with automatic extraction of measurable success criteria from requirement text. Supports Test, Analysis, Inspection, and Demonstration methods.
ISO 15288 alignedPaste any document and the parser extracts all "shall" statements, auto-classifying by type (Performance, Safety, Interface, etc.) and level. Import from text, CSV, or saved JSON projects.
Smart parsingWrite requirements using INCOSE patterns or bulk-import from existing documents. Auto-detection classifies type and level.
→Real-time 42-rule quality analysis with scoring. AI fixes violations in one click. Iterate until every requirement passes.
→Build parent-child traceability across levels. Plan verification methods. Identify orphans and gaps before they become costly.
→Save your project locally as JSON. Export to ReqIF for DOORS, CSV for spreadsheets, or share the JSON with your team.
INCOSE-TP-2010-006-04 — All 42 rules across 14 categories implemented as automated checks. 15 essential characteristics (C1–C15) for individual requirements and requirement sets.
Systems and software engineering — Life cycle processes — Requirements engineering. Requirement types, attributes, and quality criteria aligned with this international standard.
Systems and software engineering — System life cycle processes. Verification and validation planning aligned with the stakeholder needs and requirements definition process.
Requirements Interchange Format — Export compatible with IBM DOORS, DOORS Next Generation, Siemens Polarion, and other ReqIF-compliant requirements management tools.
The entire tool runs in your browser. There is no server, no database, no analytics, no cookies, and no tracking. Requirements are saved as JSON files on your own machine. You are in complete control.
