AI AGENT
Meet Zelda
Agentic AI that lives inside your documents. Query requirements, build traceability, and check compliance — without leaving the page.
Query and Analyze
Query and Analyze
Surface non-compliant requirements, find traceability gaps, identify missing evidence, and filter by verification method — across your entire program. Work that once required hours of manual filtering is a single question.
Compare Versions
Compare and Diff
When a specification changes, understanding what changed — and what it means for your program — is half the work. Zelda can compare two versions of a document, summarize what changed and why it matters, and flag requirements that shifted in scope, tightened in threshold, or were added and removed. No manual line-by-line review required.
Evidence and Compliance in One Step
Evidence and Compliance in One Step
Instruct Zelda to create an evidence record, attach a test artifact, set the verification method, and mark the requirement verified — in a single instruction. If your team tracks work in Jira, Zelda can import Jira records directly as evidence, validate the import, and link them to requirements without leaving the platform.
Author & Manage
Author and Manage Requirements
Write requirements, build traceability, and classify in bulk. When something changes upstream, Zelda traces the impact — every linked child requirement, open evidence record, and verification gap surfaced in one query. Exceptions link directly to the requirements they cover.
Risk Management
Risk Management
Create risk registers, log risks against requirements, and update risk assessments as programs evolve. Zelda can query open risks by severity, flag requirements with unmitigated risk, and surface the relationship between risk posture and compliance status, giving program managers a live view of where risk and requirements intersect.
Hi, I'm Zelda
I can answer questions about your specifications, requirements, and evidence. I can also summarize data across your programs and create requirement links when you have edit access.
Try asking me to summarize a specification or show all evidence records for a requirement to get started!
Try asking Zelda to create a risk register, create risks and link them to requirements, or write planned evidence methods for your requirements!

3.0 System Performance Requirements
3.0.1 National Space Launch System Performance Requirements
The National Space Launch System (NSLS) is designed to meet stringent performance requirements that ensure mission success, safety, and reliability. These requirements define the operational parameters for the entire system.
3.1 General Performance
3.1.1 NSLS Multi-Scenario Performance Requirements
The NSLS must demonstrate a high level of performance across multiple mission scenarios. This includes ensuring robust payload capabilities, achieving high reliability standards, and supporting rapid deployment capabilities.
3.1.2 Payload Capacity
The NSLS shall provide a minimum payload capacity of 10,000 kg to Geostationary Transfer Orbit (GTO) and 25,000 kg to Low Earth Orbit (LEO).
Scanned 142 requirements. Found 7 issues across compliance and traceability.
