THE PROBLEM

Document deadlines hit when everything is already on fire.

In every space project, documentation peaks coincide exactly with the hardest engineering phases. Review gates — SRR, PDR, CDR — demand complete deliverable packages precisely when your team is deep in design crises, firefighting, and qualification campaigns.

Engineering workload and documentation pressure across ECSS project phases

Workload composition across a typical ECSS project lifecycle. Documentation pressure compounds at every review gate — when team capacity is already exhausted.

What papyro does
📋

ECSS document templates

280+ DRDs from the ECSS catalogue with expected sections, compliance fields, and frontmatter pre-filled. Start any deliverable in seconds.

🤖

LISE — collective intelligence

LISE is grounded in authoritative space-engineering knowledge — not generic text. Every answer stays traceable to its sources, so you can see where it comes from and verify what matters.

🔀

Git-native versioning

Documents live in your own GitLab or GitHub repository. Every change is a commit. Full review workflow with merge requests and diffs.

📄

PDF & wiki builds

One click to build a Sphinx HTML wiki or xelatex PDFs — formatted to ESA house style, ready for formal review submission.

KNOWLEDGE BASE

The collective intelligence of space engineering — in every answer.

LISE doesn't generate generic text. Every answer is anchored in authoritative space-engineering knowledge and stays traceable to its sources, so your team can verify what matters.

ECSS
Built on the full standard set

Engineering, management, and product-assurance branches, with 280+ DRDs catalogued and cross-referenced — the distilled consensus of ESA working groups and review boards.

Grounded
No generic boilerplate

Answers are anchored in authoritative space-engineering knowledge rather than invented — so what LISE writes holds up to review.

Traceable
Always verifiable

Every answer points back to where it came from, so your engineers can check it and trust it — rather than taking it on faith.

AI–HUMAN WORKLOAD SPLIT

Your engineers' time belongs to the decisions only they can make.

LISE handles everything the standard already knows — structure, compliance language, DRD templates, frontmatter. The work that actually requires engineering judgement stays with your team.

EU-hosted · Encrypted at rest · GDPR-compliant
Servers in Nuremberg, Germany — your documents stay in the EU and sync to your own Git repository.
AI runs on your terms: bring your own Anthropic / OpenAI key, or point papyro at your own AWS Bedrock / Google Vertex account to keep Claude in an EU region under your own cloud contract.
