From Requirements to Reality
Engineering requirements that actually pass review
RequirementSpec analyses your requirements against ISO 26262, DO-178C, EN 50128 and more — scoring quality, flagging issues, and rewriting weak requirements in seconds.
Bad requirements are the most expensive mistake in engineering
Vague language
Words like "adequate", "user-friendly" and "as needed" slip past review and surface as disputes months later — when they're far more expensive to fix.
Missing traceability
Requirements without a clear link to source standards or test evidence create audit gaps that stall certification and cost engineering weeks of rework.
Manual reviews
Senior engineers spend hours combing through specs line by line, catching some issues and missing others — a process that doesn't scale with headcount.
How it works
Paste your requirement
Drop in a single requirement or upload a batch of up to 100 from CSV or Excel — no formatting required.
AI reviews instantly

Everything you need to ship clean requirements
Quality scoring
Six-dimension scoring across clarity, testability, measurability, atomicity, traceability and compliance.
Batch analysis
Analyse up to 100 requirements at once and export a consolidated report for the whole set.
Verification methods
Get suggested verification methods — test, analysis, inspection or demonstration — for every requirement.
Rationale review
Rationale and justification statements are checked for strength, and flagged when missing or weak.
Standards compliance
