Carbon · Documentation engine for regulated software
Submission-ready documents in days, not months.
Carbon turns eight intake answers and the documents you already have into a signed, traceable package: PRD, SRD, threat model, compliance evidence and risk register. It runs in your environment, on your LLM.

Figures come from Carbon reference projects. Your timeline depends on scope. We'll tell you during the trial whether the 5-day reference holds for your build.
The old way
Documentation still ships last.
In regulated software, that means the product doesn't ship either. Your ALM tool stores what someone already wrote. Nothing in your stack writes the package the reviewer actually asks for.
Manual authoring
- Wk 1–3
Kickoff. Template debates. Who owns the threat model?
- Wk 4–7
Three or four authors, each with their own vocabulary.
- Wk 8–10
The PRD and SRD disagree on three numbers. Reconciliation begins.
- Wk 11–12
Compliance asks for evidence that doesn't exist yet.
- Wk 13+
The reviewer sends it back. You restart from week eight.
With Carbon
5 business days
- Day 1
Eight intake answers from your product owner, compliance lead and security architect.
- Day 2
Your PDFs, notes and existing requirements become a constraint log.
- Day 3
Eight agents author every artifact in parallel.
- Day 4
Every requirement is scored against EARS patterns and INCOSE rules.
- Day 5
A signed, hash-chained bundle, approved at the final gate.
Why it holds up in review
Written by agents. Checked by rules. Signed by people.
/01
Deterministic scoring
RQS grades every requirement with EARS pattern detection and INCOSE rule checks. No model grades its own work.
/02
Every claim sourced
Each statement links back to an intake answer or an uploaded document. Nothing appears without a source.
/03
Five named gates
A named reviewer approves every phase, so problems surface at gate two, not week twelve.
/04
Tamper-evident
The audit log is hash-chained. One command detects any edit made after export.
Frameworks
One build across every framework you answer to.
Select HIPAA and ISO 42001 and you get one integrated risk register, not two parallel ones. Carbon resolves the overlap deterministically.

Carbon sits beside Jira, DOORS, Jama and Polarion. It doesn't replace them. EARS-scored requirements sync natively into Jira, and a REST API connects Confluence, GitHub and Notion.
The bundle
Eight artifact types. One signed package.
- BRD / PRD / SRDBusiness, product and software requirements. The SRD is EARS-scored.
- Threat modelSTRIDE security architecture and threat analysis.
- EvidenceFramework-specific evidence, generated with the requirements instead of hunted down at week 12.
- TraceabilityA matrix linking stakeholder need to requirement to constraint.
- Risk registerRisks and mitigations, merged across every framework you select.
- ArchitectureSystem diagrams, emitted from the same run.
- Audit trailA hash-chained log of who approved what, when and why.
Start with one project
Put a real project through Carbon.
Bring a real certification, your framework set and one stakeholder. If the 5-day reference doesn't hold for your build, you'll know in a week, not a quarter.
- /01
A 45-minute deep-dive built around your frameworks.
- /02
A trial on one real project, in your environment.
- /03
Results reviewed with your team, then a proposal.
