Supersalience

Built on Helix-DB · Graph + Vector

Memory
and Knowledge
for AI Agents

Supersalience is a typed knowledge graph and long-lived memory backend for agentic systems. Sync observations, resolve canonical entities, recall what matters — across sessions, surfaces, and time.

01 // What it does

A backend for durable agent context.

01 · graph

Knowledge graph

Entities, relations, and observations with alias resolution, soft-merge, and TTL-bucketed expiry baked in.

02 · search

Semantic search

Polymorphic search over text, vectors, contacts, and seed entities — with neighborhood expansion to bounded depth.

03 · memory

Durable memory

Per-connection facts with categories, sources, and stability. Recall, summarize, update, forget.

04 · sessions

Session continuity

Conversation seed entities carry across turns so multi-step agents stay grounded without bespoke caching.

05 · ttl

Time-aware truth

Bucketed lifetimes — days, weeks, months, year+, indefinite — so stative facts expire instead of haunting your prompts.

06 · scale

Built on Helix

Storage and ANN vector search are powered by helix-db — the infinitely scalable graph-vector database, written in Rust.

02 // Quickstart

One endpoint. Three primitives.
