The private memory
your AI runs on.
Chordian is the institutional memory and search layer that enterprises and AI builders own, deploy, and control — so every agent, assistant, and team always knows what your organisation knows.
Two products.
Complete memory ownership.
Chordian Memory and Chordian Search are built to work together. Search feeds Memory. Memory makes Search smarter. Every query compounds your institutional knowledge.
Chordian Memory
Your organisation's institutional memory — self-building, always current, privately yours. Every document, decision, relationship, and event continuously ingested, structured, and maintained. Humans and agents read and write to the same source.
- ✓350+ connectors — email, Slack, CRM, legal, databases, web
- ✓Entity Coherence — one consistent identity across every system
- ✓Bi-temporal state — what was true, and when it was believed to be true
- ✓Conflict detection with confidence scoring — surfaced, never silenced
- ✓Automatic decay — stale facts lose confidence, fresh signals rise
- ✓Deploy in your cloud, VPC, or your own servers
Chordian Search
Not a search bar. An autonomous AI search agent. Chordian Deep Search runs seven parallel retrieval paths across your private memory and the live web, fuses them via Reciprocal Rank Fusion, and reasons through complex questions until it reaches a confident, source-attributed answer.
- ✓7 parallel retrieval paths — Instant, Semantic, Keyword, Graph, GraphRAG, Web Intelligence, Deep Search
- ✓RRF fusion — ranked, source-attributed, confidence-scored output
- ✓Deep Search is an autonomous AI agent — reasons until confident
- ✓Every search writes back to Memory — compounds over time
- ✓Dramatically fewer tokens — your LLM reasons, not re-learns
- ✓Structured JSON output with full provenance on every call
Seven paths. One answer.
Fully reasoned.
Deep Search is an AI agent, not a retrieval function. It dispatches seven parallel paths, fuses results, and reasons autonomously until it reaches a confident, source-attributed answer to even the most complex multi-hop questions.
Instant Search
Pre-indexed, sub-100ms. Answers high-frequency queries before the user finishes typing.
Semantic Search
Meaning-based retrieval. Finds conceptually related content even when exact words don't match.
Keyword Search
BM25 exact-match precision for proper nouns, contract numbers, and structured data queries.
Graph Search
Relationship traversal across your private memory. The answer is in the connection, not the document.
GraphRAG
Graph-augmented generation grounded in your private memory. Higher accuracy on relational questions.
Web Intelligence
Real-time enrichment via the Chordian Agentic Crawler. Live signals integrated with private memory.
Deep Search
Autonomous agentic retrieval. Re-queries, cross-references, and reasons across multiple hops until confident.
RRF
Reciprocal Rank Fusion combines all active paths into one ranked result with source attribution and confidence scores.
One consistent understanding
of everything that matters.
Chordian's Entity Coherence engine maintains a single shared understanding of every person, company, deal, and decision across all your agents, systems, and sessions — resolved at ingest, not at query time.
Your systems say:
Your AI never hallucinates which version is correct. Every agent, every system, every session — the same consistent understanding, resolved at ingest.
Deploy where your data
has to live.
In every configuration, your data does not train any external model. Ever.

Technical depth and strategic thinking on the institutional memory layer — for builders and enterprise teams.
What is institutional AI memory — and why your organisation needs it now
Most AI deployments fail not because the model is wrong, but because it doesn't know what your organisation already knows. Here's the architecture that changes that.
TechnicalAgentic search vs. RAG: why retrieval alone isn't enough for enterprise AI
Retrieval-Augmented Generation was a step forward. Agentic search — which reasons, re-queries, and refines until confident — is the next one.
ArchitectureEntity Coherence: the missing layer in enterprise AI memory
When your CRM, email, and Slack all refer to the same person differently, your AI hallucinates. Entity Coherence resolves this at ingest — not at query time.
Start in minutes. Own it permanently.
Your AI is only as good
as what it remembers.
Most AI deployments fail not because the model is wrong — but because it doesn't know what your organisation knows. Chordian solves that.
