Watch the beat
Research agents monitor the sources you choose and surface developments that belong in your publication, not whatever happens to be loud today.
Open-source, AI-assisted publishing
A newsroom with a long memory.
Papyrus turns one subject worth following into a living publication. Research agents watch the beat, editors shape the coverage, and every story keeps its sources, concepts, and decisions attached.

The newsroom system
From signal to record.
A feed forgets. Papyrus accumulates context, preserves provenance, and makes editorial decisions visible.
Build the memory
References, people, organizations, claims, and relationships become a reviewed knowledge base that gets more useful with every reporting cycle.
Exercise judgment
Editors choose the angle, open assignments, challenge the evidence, and decide what is ready. Automation works for the desk, not instead of it.
Publish an edition
Turn reporting packets into reviewed copy, assemble sections and editions, and publish a site whose shape follows the subject you cover.
Delegated responsibility
You choose how much we help
You can run the whole stack yourself. If you want help, we can host a publication for you, operate a dedicated deployment in your account, or build a newsroom to your scope.

What is Papyrus?
Papyrus is an open-source publishing and newsroom system for a specific beat. Research agents and human editors monitor sources, maintain a publication-specific knowledge base, prepare reporting packets, review drafts, and publish editions.
Does Papyrus have to run in Anthus infrastructure?
No. It is designed to run from your AWS account. Your content, data, and infrastructure stay under your control.
Who pays for what?
Hosted: Anthus pays the infrastructure; model calls are bring your own key or capped by the plan. Dedicated: you pay AWS and your model providers directly; Anthus charges only the operations fee. Engagement: stated in the scope.
What happens if I stop paying?
Hosted workspaces can be exported and are kept read-only for 90 days. Dedicated deployments stay in your account untouched; we stop operating them and delete nothing.
What does dedicated actually mean?
Your data never leaves your account. Your own model contracts and keys. Your compliance boundary. No noisy neighbors. You keep running if Anthus disappears. The monthly fee buys updates, monitoring, and a team that has run the same deployment first: we update our own deployments before yours.
Can I start hosted and move to dedicated?
Yes, and the reverse.
Where can I see it working?
This site is a Papyrus publication. The newspaper lives at /information, and the newsroom behind it at /newsroom.
