Semiont

Semiont is an open-source platform that builds a knowledge base directly from your documents — annotated, linked, and extended by humans and AI agents working together.

Most organizations sit on vast document collections that are searchable but not understood. Semiont closes that gap. Import your corpus — contracts, research papers, product specs, regulatory filings — and the system immediately begins identifying entities, proposing annotations, and linking related concepts across documents. Domain experts review and refine what AI proposes; AI scales what experts start. The result is a grounded knowledge graph where every node traces back to a specific passage in a specific document.

That graph becomes infrastructure. Use it to power semantic search and contextual recommendations in your products. Feed it to RAG pipelines so your AI assistants answer from verified, cited sources instead of hallucinating. Automate compliance checks by querying relationships across regulatory documents. Surface hidden connections across research portfolios that would take analysts months to find manually. Every annotation your team creates — or your agents produce — compounds into an asset that makes the next query smarter, the next review faster, and the next product feature possible.

Built on the W3C Web Annotation standard — portable, interoperable, and sovereign on your infrastructure.

Why Semiont?

Eliminate Cold Starts — Import a set of documents and the six flows immediately begin producing value: AI agents detect entity mentions, propose annotations, and generate linked resources while humans review, correct, and extend the results. The knowledge graph grows as a byproduct of annotation — no upfront schema design, manual data entry, or batch ETL pipeline required.

Calibrate the Human–AI Mix — Because humans and AI agents share identical interfaces, organizations can dial the mix to fit their constraints. A domain with abundant expert availability and a high accuracy bar can run human-primary workflows with AI suggestions; a domain rich in GPU capacity but short on specialists can run agent-primary pipelines with human spot-checks. Supervision depth, automation ratio, and quality gates are deployment decisions — not architectural rewrites.

Core Tenets

Peer Collaboration — Humans and AI agents are architectural equals. Every operation flows through the same API, event bus, and event-sourced storage regardless of who initiates it. Any workflow can be performed manually, automated by an agent, or done collaboratively.

Document-Grounded Knowledge — Knowledge is always anchored to source documents. Annotations point into specific passages; references link documents to each other. The knowledge graph is a projection of these grounded relationships, not a replacement for the original material.

Six Collaborative Flows

Humans and AI agents work as peers through six composable workflows:
