YantrikDB — A Cognitive Memory Engine for Persistent AI Systems

The memory engine for AI that actually knows you.

Get Started in 60 Seconds

For AI agents (MCP — works with Claude, Cursor, Windsurf, Copilot)

pip install yantrikdb-mcp

Add to your MCP client config:

{
  "mcpServers": {
    "yantrikdb": {
      "command": "yantrikdb-mcp"
    }
  }
}

That's it. The agent auto-recalls context, auto-remembers decisions, and auto-detects contradictions — no prompting needed. See yantrikdb-mcp for full docs.

As a Python library

pip install yantrikdb

The engine ships a default embedder (potion-base-2M, ~7 MB, distilled from BGE-base-en-v1.5) — record_text() / recall_text() work out of the box. No sentence-transformers install. No first-run model download. No ONNX runtime. Just one pip install.

import yantrikdb

# Default: bundled embedder, dim=64. Just works.
db = yantrikdb.YantrikDB.with_default("memory.db")

db.record("Alice is the engineering lead", importance=0.8, domain="people")
db.record("Project deadline is March 30", importance=0.9, domain="work")
db.record("User prefers dark mode", importance=0.6, domain="preference")

results = db.recall("who leads the team?", top_k=3)
# → [{"text": "Alice is the engineering lead", "score": 1.0}, ...]

db.relate("Alice", "Engineering", "leads")
db.get_edges("Alice")

db.think()  # consolidate, detect conflicts, mine patterns

db.close()

Want higher-quality embeddings?

Three opt-in upgrade paths, in increasing weight:

# 1. Larger bundled variant — downloads on first call, caches under
#    your user data dir. Self-hosted from yantrikos/yantrikdb-models;
#    no HuggingFace dependency, no rate limits.
db = yantrikdb.YantrikDB("memory.db", embedding_dim=256)
db.set_embedder_named("potion-base-8M")   # ~28 MB, ~92% MiniLM
# or:  db.set_embedder_named("potion-base-32M")  # ~121 MB, ~95% MiniLM

# 2. Bring your own embedder (sentence-transformers, fastembed, custom).
from sentence_transformers import SentenceTransformer
db = yantrikdb.YantrikDB("memory.db", embedding_dim=384)
db.set_embedder(SentenceTransformer("all-MiniLM-L6-v2"))

# 3. Slim build (no bundled embedder, must set_embedder yourself).
#    For deployments where the ~7 MB bundle is intolerable.
#    Rust:  yantrikdb = { version = "0.7", default-features = false }

Path	Quality vs MiniLM	Size on disk	Install network
Bundled default (`with_default`)	~89%	~7 MB (bundled)	none
`set_embedder_named("potion-base-8M")`	~92%	~28 MB (cached)	first call only
`set_embedder_named("potion-base-32M")`	~95%	~121 MB (cached)	first call only
`set_embedder(MiniLM)`	100% (baseline)	~80 MB	sentence-transformers' own download

As a Rust crate

[dependencies]
yantrikdb = "0.7"

# Want set_embedder_named() for runtime model upgrades?
# yantrikdb = { version = "0.7", features = ["embedder-download"] }

# Slim build (no bundled embedder, no network code path):
# yantrikdb = { version = "0.7", default-features = false }

The Problem

Current AI memory is:

Store everything → Embed → Retrieve top-k → Inject into context → Hope it helps.

That's not memory. That's a search engine with extra steps.

Real memory is hierarchical, compressed, contextual, self-updating, emotionally weighted, time-aware, and predictive. YantrikDB is built for that.

Why Not Existing Solutions?

Solution	What it does	What it lacks
Vector DBs (Pinecone, Weaviate)	Nearest-neighbor lookup	No decay, no causality, no self-organization
Knowledge Graphs (Neo4j)	Structured relations	Poor for fuzzy memory, not adaptive
Memory Frameworks (LangChain, Mem0)	Retrieval wrappers	Not a memory architecture — just middleware
File-based (CLAUDE.md, memory files)	Dump everything into context	O(n) token cost, no relevance filtering

Benchmark: Selective Recall vs. File-Based Memory

Memories	File-Based	YantrikDB	Token Savings	Precision
100	1,770 tokens	69 tokens	96%	66%
500	9,807 tokens	72 tokens	99.3%	77%
1,000	19,988 tokens	72 tokens	99.6%	84%
5,000	101,739 tokens	53 tokens	99.9%	88%

At 500 memories, file-based exceeds 32K context windows. At 5,000, it doesn't fit in any context window — not even 200K. YantrikDB stays at ~70 tokens per query. Precision improves with more data — the opposite of context stuffing.

Evidence (reproducible)

Every claim here points at a runnable harness — not a static number. Each is gated in CI (.github/workflows/benchmark.yml) so a regression fails the build.

Recall doesn't degrade as the corpus grows, and stays fast. python -m yantrikdb.eval.benchmark holds a fixed signal corpus while adding distractors and measures recall + latency at each scale. Sample run: recall@k 0.938 → 0.929 as memories grow 7×, with p95 recall latency under 3 ms. regression_check() is the CI gate.
The knowledge graph earns its keep on connected data. python -m yantrikdb.eval.graph_lift measures recall with entity-expansion ON vs OFF. Verdict on the connected corpus: +2.5% recall, +1.7% MRR — graph expansion helps where memories are actually linked.
Apples-to-apples vs other memory systems. python -m yantrikdb.eval.competitors scores YantrikDB, mem0, Zep, and Letta on the same corpus, same queries, same metrics, no per-system tuning. (Competitors run once their libraries are installed; results are not pre-tuned.)

These run dependency-free on the bundled embedder, so anyone can reproduce them with one command.

Architecture

Design Principles

Embedded, not client-server — single file, no server process (like SQLite)
Local-first, sync-native — works offline, syncs when connected
Cognitive operations, not SQL — record(), recall(), relate(), not SELECT
Living system, not passive store — does work between conversations
Thread-safe — Send + Sync with internal Mutex/RwLock, safe for concurrent access

Vector Index (HNSW) — semantic similarity search across memories
Graph Index — entity relationships, profile aggregation, bridge detection
Temporal Index — time-aware queries ("what happened Tuesday", "upcoming deadlines")
Decay Heap — importance scores that degrade over time, like human memory
Key-Value Store — fast facts, session state, scoring weights

Decoupled Write Path (v0.6.6+)

The vector index is structured as a two-tier LSM: a small mutable delta and an immutable HNSW cold tier swapped atomically via ArcSwap. Foreground writes only touch the delta (brief lock, O(1) push); HNSW work amortizes on a dedicated compactor thread. This is what eliminated the production wedge where sustained writes starved readers — see CONCURRENCY.md and docs/decoupled_write_path_rfc.md.

The structural invariant. Foreground (P1) and background (P3) do not share a lock primitive that holds for non-O(1) work. The cold tier is read lock-free via ArcSwap; the delta's RwLock is held for the O(1) push only. This is what makes "no single background task can wedge reads, writes, or recovery" enforceable — see CONCURRENCY.md Rules 2 and 3 for the names and failure modes if violated.

Cluster Mode (RFC 010 + Phase 6 RYW)

For multi-node deployments, yantrikdb-server wraps the engine with openraft for leader-elected replication. The four cluster-mutation primitives take the openraft commit-log index as their seq, so all nodes agree on a single global monotonic sequence — read-your-writes works across the cluster, not just within a node.

flowchart LR
    L["Leader<br/>HTTP request"]
    LR["Leader engine<br/>record_with_rid(seq=Some(log_idx))"]
    OR["openraft<br/>commit log"]

    R["Reader on any node<br/>recall_with_seq(min_seq=log_idx)"]

    L --> LR
    LR --> OR
    OR -->|replicate + apply| F1

    F1 -.->|"visible_seq[ns] reaches log_idx"| R
    F2 -.->|"visible_seq[ns] reaches log_idx"| R
    LR -.->|"visible_seq[ns] reaches log_idx"| R

Each record_with_rid / tombstone_with_rid / upsert_entity_edge_with_id / delete_entity_edge_with_id accepts an optional seq: Option<u64>. Single-node callers pass None and the engine allocates; cluster appliers pass Some(commit_log_index) and the engine ratchets vec_seq up to at least that value via fetch_max. After apply, visible_seq[namespace] reaches the log index, so any subsequent recall_with_seq(min_seq=N) blocks just long enough for the local node to have applied through index N — and no longer.

Memory Types (Tulving's Taxonomy)

Type	What it stores	Example
Semantic	Facts, knowledge	"User is a software engineer at Meta"
Episodic	Events with context	"Had a rough day at work on Feb 20"
Procedural	Strategies, what worked	"Deploy with blue-green, not rolling update"

All memories carry importance, valence (emotional tone), domain, source, certainty, and timestamps — used in a multi-signal scoring function that goes far beyond cosine similarity.

Key Capabilities

Relevance-Conditioned Scoring

Not just vector similarity. Every recall combines:

Semantic similarity (HNSW) — what's topically related
Temporal decay — recent memories score higher
Importance weighting — critical decisions beat trivia
Graph proximity — entity relationships boost connected memories
Retrieval feedback — learns from past recall quality

Weights are tuned automatically from usage patterns.

Conflict Detection & Resolution

When memories contradict, YantrikDB doesn't guess — it creates a conflict segment:

"works at Google" (recorded Jan 15) vs. "works at Meta" (recorded Mar 1)
→ Conflict: identity_fact, priority: high, strategy: ask_user

Resolution is conversational: the AI asks naturally, not programmatically.

Semantic Consolidation

After many conversations, memories pile up. think() runs:

Consolidation — merge similar memories, extract patterns
Conflict scan — find contradictions across the knowledge base
Pattern mining — cross-domain discovery ("work stress correlates with health entries")
Trigger evaluation — proactive insights worth surfacing

Proactive Triggers

The engine generates triggers when it detects something worth reaching out about:

Memory conflicts needing resolution
Approaching deadlines (temporal awareness)
Patterns detected across domains
High-importance memories about to decay
Goal tracking ("how's the marathon training?")

Every trigger is grounded in real memory data — not engagement farming.

Multi-Device Sync (CRDT)

Local-first with append-only replication log:

CRDT merging — graph edges, memories, and metadata merge without conflicts
Vector indexes rebuild locally — raw memories sync, each device rebuilds HNSW
Forget propagation — tombstones ensure forgotten memories stay forgotten
Conflict detection — contradictions across devices are flagged for resolution

Sessions & Temporal Awareness

sid = db.session_start("default", "claude-code")
db.record("decided to use PostgreSQL")  # auto-linked to session
db.record("Alice suggested Redis for caching")
db.session_end(sid)
# → computes: memory_count, avg_valence, topics, duration

db.stale(days=14)    # high-importance memories not accessed recently
db.upcoming(days=7)  # memories with approaching deadlines

Worked example: Wirecard (RFC 008 substrate — with honest limits)

For nearly a decade, Wirecard's filings and EY's audit attested to €1.9B in Philippine escrow accounts. In June 2020 both banks and the central bank formally denied the accounts existed.

When the source_lineage fields are hand-populated — EY as [wirecard, ey] to capture audit dependence on Wirecard-provided documents, BSP as [bsp, bpi, bdo] to capture restatement of the commercial banks — RFC 008's ⊕ discounts the dependent claims, and the contest operator's temporal split distinguishes present-tense contradictions from historical state changes. On this hand-populated data, the substrate produces useful annotations.

Honest limits (surfaced by Phase 2 empirical testing, Apr 2026):

On naturalistic evidence where a real agent populates the fields, the substrate's gates don't reliably fire. Cases B and C of the Phase 2 eval need an extractor/canonicalizer (not yet built) to work; Case A exposed that ⊕ is mathematically incapable of flipping decisions at realistic N, regardless of coefficient tuning.
Current claim: structured schema for evidence provenance/temporal/conflict annotation, useful for audit and inspection. The dependence-discount operator works on curated inputs but needs replacement before it can drive decisions.
Not a current claim: "decision-improvement substrate for AGI-capable agents." That framing is withdrawn pending RFC 009.

See docs/showcase/wirecard.md for the full walkthrough including the Phase 2 negative result and the gold-state ablation that partitioned operator failure from extraction failure. Run the hand-populated demonstration directly:
