Meet Zelda, Your AI Agent For Requirements Management
Zelda handles time-consuming requirements work so engineering teams move faster, stay ahead of compliance gaps, and maintain program-level visibility.
Query and Analyze
Surface non-compliant requirements, find traceability gaps, and filter by verification method across your entire program. Work that once required hours of manual filtering is resolved with a single question.
Example: "Show me all shall-statements in Section 4 that don't have evidence records."
Evidence and Compliance in One Step
Keep verification records complete, linked, and audit-ready without the busywork.
Example: "Create an evidence record for REQ-5.1, attach the vibration test report, and mark it as Test."
Author and Manage Requirements
Instruct Zelda to write new requirements or establish parent-child traceability links across specifications. Every action draws on the full context of your program.
Example: "Create a new thermal requirement under REQ-4.3 with a shall statement for operating temperature range."
Summarize and Identify Gaps
Get instant overviews of specification status, compliance posture, and requirement coverage. Zelda analyzes your documentation and suggests new requirements to close gaps.
Example: "Summarize the compliance status of the ARINC 653 spec and flag any requirements missing verification."
Your Requirements Data Stays Yours
Zelda runs entirely within Stell's AWS GovCloud authorization boundary, powered by AWS Bedrock. Every prompt, response, and AI interaction stays within that boundary, adhering to the same security controls that govern the entire product.
Stell does not train models on any user data.
Every AI Action Has A Name On It
No change executes without explicit user approval. Once approved, every action is logged and traceable to the human who authorized it.
Security Without Compromise
Every AI interaction operates with authorization boundaries, access controls, and audit trails. AI-generated content is treated exactly like human-generated content: date-stamped and attributed.
