Cognitive memory for AI agents — FSRS-6 spaced repetition, 29 brain modules, 3D dashboard, single 22MB Rust binary. MCP server for Claude, Cursor, VS Code, Xcode, JetBrains.

Vestige

The cognitive engine that gives AI a brain.

Your AI forgets everything between sessions. Vestige fixes that.

Built on 130 years of memory research — FSRS-6 spaced repetition, prediction error gating, synaptic tagging, spreading activation, memory dreaming — all running in a single Rust binary with a 3D neural visualization dashboard. 100% local. Zero cloud.

What's New in v2.0.5 "Intentional Amnesia"

The first AI memory system that can actively forget. New suppress tool applies top-down inhibitory control over retrieval — each call compounds a penalty (up to 80%), a background Rac1 worker fades co-activated neighbors over 72h, and it's reversible within a 24h labile window. Never deletes — the memory is inhibited, not erased.

Based on Anderson et al. 2025 (Suppression-Induced Forgetting) and Cervantes-Sandoval et al. 2020 (Rac1 synaptic cascade). 24 tools · 30 cognitive modules · 1,284 tests.
