Exact evidence
Answers include quotations and locators tied to immutable source versions.
Private institutional memory
Know what is current, what changed, and the evidence behind it.
Everifact gives high-trust teams a private, source-grounded memory across documents, notes, decisions, systems, and correspondence.
Evidence-level citations
Temporal knowledge
Private deployment

Exact documents and versions
Understanding
Claims, conflicts and review
Answers
Current truth with evidence
Every answer is traceable
Citations retain the source, exact version, locator, and supporting excerpt.
History is not overwritten
Current, historical, contradicted, and superseded facts remain distinguishable.
Your data plane stays private
Dedicated private-cloud and on-premises deployment keeps knowledge isolated.
Beyond chat with documents
A durable evidence system for knowledge that changes.
Everifact preserves immutable source versions, builds a retrieval index, and connects evidence-derived claims without silently rewriting the record. Teams can ask questions, inspect the supporting material, and see how an answer changed over time.
Important conflicts and uncertain claims enter a human review queue. The result is institutional memory that can be checked, corrected, and trusted.
Temporal truth
Distinguish what is current from what was once true, contradicted, or superseded.
Human verification
Route consequential, conflicting, and low-confidence claims to named reviewers.
Private by design
Keep source objects, embeddings, retrieval indexes, and graph data inside the customer data plane.
Obsidian coexistence
Search, chat, review, and publish explicit outputs without forcing teams to abandon their vaults.
Model neutral
Use approved local or external models through an OpenAI-compatible gateway abstraction.
Evidence lifecycle
From a source item to a reviewable answer.
Every generated assertion keeps its lineage. Retrieval combines semantic and lexical signals, while authorization is enforced before evidence is returned or sent to an approved model route.
01
Preserve
Store the immutable original, remote identity, access rules, and exact source version.
02
Understand
Parse structure, index evidence, and extract candidate claims, entities, events, and decisions.
03
Verify
Surface conflicts and uncertainty for human review without changing the source document.
04
Answer
Return an explicit answer or abstention with supporting excerpts and versioned citations.
Deployment and boundaries
Private knowledge truth, separate from agent execution.
Everifact is authoritative for sources, versions, claims, citations, and timelines. AgentKnow governs agent and runtime operations. AgentKnow may consume Everifact through governed REST or read-only MCP interfaces, but neither product is required to run the other.
Each customer receives an isolated data plane. Embeddings and reranking are local by default; only retrieved excerpts may use a customer-approved external model route.
Dedicated private cloud
A customer-isolated data plane operated with explicit model and access policies.
On-premises
Deploy inside customer-controlled infrastructure where residency and network boundaries require it.
REST and MCP
Expose governed search, evidence answers, sources, and timelines to approved applications and agents.
Connected sources
Start with Obsidian and files, then extend to Microsoft, Google, and customer sources.
