SignetAI | Self-Hosted AI Memory for Agents

2 min read Original article ↗

Identity, memory, and secrets that survive the model switch.

Signet keeps agent state outside any single model or harness. It preserves the exact record, builds useful context from it, and keeps credentials out of the model window.

Ambient Memory

Every session is automatically distilled into structured memory. No tool calls, no manual saves — your agent wakes up knowing what happened yesterday.

Knowledge Graph

Entities and relationships extracted with high precision. Graph traversal allows for deep context retrieval.

Inspect Everything

Memory is not a black box. Browse, search, and edit through a refined dashboard with full provenance.

Cross-Platform

A unified agent state layer that keeps identity and memory coherent across every major AI agent harness.

Encrypted Secrets

Industry-standard encryption at rest. Agents utilize credentials without ever exposing plaintext.

Multi-Agent

Granular visibility controls. Define isolated, shared, or group memory scopes for swarms.

Context Ranking

Inspectable ranking, provenance, and dampening keep useful context visible without flooding the model window.

Methodology and full results →

Your agent has memory in five minutes.

01

Install

$ curl -fsSL https://signetai.sh/install.sh | bash

same binary via package managers: npm i -g signetai or bun add -g signetai

02

Setup

Run signet setup, pick your harness, and the daemon starts automatically. Hooks are installed. Identity files are created.

03

Work

Open your coding agent and start a session. Memory extraction happens automatically. Next session, context is already there.
