Areev is a purpose-built memory database. Importance scoring, temporal reasoning, biological decay, and cryptographic erasure are native to the engine — not assembled from separate systems. Memory that compounds.
These capabilities don't exist in any existing database. Areev was built around them — not on top of them.
Vector DBs rank by similarity. Caches don't rank at all. Neither understands that some memories matter more than others.
→ Not in Pinecone, Weaviate, RedisWhen something happened changes what it means. No existing database can answer "what did the user believe about X, as of Tuesday?"
→ Not in Postgres, Elasticsearch, QdrantMemories that aren't reinforced should fade. No database has a native forgetting curve — you'd need background jobs scanning every store.
→ Not in any existing database"Delete user X" means scanning five systems and hoping you got everything. Or rotate one key and it's gone. O(1).
→ Not in any existing databaseA memory write needs to store the fact, its embedding, its timestamp, and its importance score atomically. With assembled parts, any can fail independently.
→ Impossible across 5 separate systemsThree stages transform noisy agent interactions into structured, searchable, deletable memory grains.
Raw events — tool calls, LLM outputs, user messages — enter the observation buffer. Nothing is stored permanently yet.
The importance scorer evaluates signal density. High-value observations are synthesized into typed grains. Low-signal events decay.
Agents query by semantic similarity (HNSW), keyword (BM25), or graph (Hexastore). RRF fusion combines all three.
Instead of replaying raw transcripts, Areev stores semantic grains — the compressed, typed residue of every meaningful interaction. 10 grain types cover the full cognitive surface.
When a deletion request arrives, Areev rotates the cryptographic key that wraps the target grain. The data becomes permanently unreadable in O(1) time — no scans, no scrubs, no latency. 90+ automated compliance checks across 7 regulations.
The human mind, as a primitive. Starting now.
