Requirement quality checks
Run a requirements set through the checks above and get a finding per requirement, with the reason and the offending text.
ECSS Copilot · Open source · Working prototype
Catch requirement problems before your review board does.
ECSS Copilot checks space-project requirements for vague wording, multiple shalls, missing units and open TBDs, drafts a verification matrix, and exports everything to Excel.
Open source · Based in Houston, Texas · For US and international space teams

TBD
ECSS Copilot
Less paperwork, more engineering.
Space projects run on requirements. ECSS Copilot takes on the repetitive checking and first drafts, so engineers can spend their time on judgement.
Vague wording
Flags terms like "adequate", "user-friendly", "as appropriate" or "fast" that can't be verified.
Multiple shalls
Spots requirements that bundle several obligations into one statement, so each can be traced and verified on its own.
Missing units
Catches numbers without units or tolerances before they turn into interface or test problems.
TBDs and TBCs
Lists every open TBD/TBC so nothing slips through to a review unresolved.
Draft verification matrix
Generate a first-cut verification matrix (proposed method per requirement: test, analysis, inspection or review of design) for engineers to review.
Export to Excel
Export findings and the draft matrix to an Excel workbook that fits into the way your team already works.
Engineer in the loop
Outputs are drafts for qualified engineers to review. Nothing replaces your sign-off.
Open source
The code is open, so you can inspect how every finding is produced and run it yourself.
Your data stays yours
Built with confidentiality and export-control realities of space programmes in mind.
Coming later
