Write better requirements.

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

INCOSE GtWR v4 ISO/IEC/IEEE 29148 ISO/IEC/IEEE 15288 OMG ReqIF

Poor requirements cost programmes millions.

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.

✕ Before
The system should be able to process data in a fast and reliable manner, where possible, including but not limited to sensor inputs etc.
✓ After — AI Improved
The Data_Processor shall process each sensor input within 200 ± 20 ms with MTBF ≥ 5000 hours.
Quality Score 94% (A)
R1 ✓ R2 ✓ R5 ✓ R6 ✓ R7 ✓ R8 ✓ R9 ✓ R10 ✓ R14 ✓ R18 ✓ R33 ✓ R34 ✓ — 40/42 rules passed

Everything you need.
Nothing you don't.

42-Rule Quality Engine

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 analysis

AI Improvement

One click transforms vague, passive, untestable requirements into INCOSE-compliant statements. Fixes passive voice, vague terms, escape clauses, superfluous infinitives, absolutes, and abbreviations automatically.

Automated rewriting

DOORS ReqIF Export

Export 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 compatible

Traceability Matrix

Visualise parent-child relationships across four requirement levels: Stakeholder Need → System → Subsystem → Component. Automatically detects orphan requirements missing upward traces.

4-level hierarchy

V&V Planning

Verification method distribution dashboard with automatic extraction of measurable success criteria from requirement text. Supports Test, Analysis, Inspection, and Demonstration methods.

ISO 15288 aligned

Bulk Import

Paste 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 parsing

Four steps. Zero friction.

01

Author or Import

Write requirements using INCOSE patterns or bulk-import from existing documents. Auto-detection classifies type and level.

02

Analyse & Improve

Real-time 42-rule quality analysis with scoring. AI fixes violations in one click. Iterate until every requirement passes.

03

Trace & Verify

Build parent-child traceability across levels. Plan verification methods. Identify orphans and gaps before they become costly.

04

Export & Share

Save your project locally as JSON. Export to ReqIF for DOORS, CSV for spreadsheets, or share the JSON with your team.

Built on the standards
that matter.

OMG ReqIF 1.2

Requirements Interchange Format — Export compatible with IBM DOORS, DOORS Next Generation, Siemens Polarion, and other ReqIF-compliant requirements management tools.

Systems engineers. Academics.
Defence teams. Students.

Perfect for teaching requirements engineering in the classroom. Students see quality scores improve in real-time as they fix each violation — far more engaging than marking papers manually.
University Faculty · SE Education
We use it in early-phase projects before committing to DOORS. It catches 80% of quality issues upfront, and the ReqIF export means nothing is wasted when we move to the formal tool.
Systems Engineer · Defence Programmes
The AI improvement feature is a game-changer for workshop settings. Participants draft requirements, hit the button, and immediately understand what good looks like versus what they wrote.
Training Facilitator · Professional Development
