Universal, Cross-Tool Persistent Memory for AI Assistants
Why Aethos How It Works Windows Setup macOS Setup MCP Tools Privacy
Every time you start a new chat, your AI assistant forgets everything — your stack, preferences, project decisions, your name. You repeat yourself every session, across every tool.
Aethos Memory fixes this. One MCP server, one database, every AI assistant remembers everything — forever.
Repeat your tech stack every new session AI already knows your stack from session 1
Start from scratch in every AI tool Claude Code, Cursor, OpenCode share one memory bank
AI forgets your name and preferences Permanent identity and preference store across all tools
Architecture decisions lost between sessions Every decision is stored and retrieved automatically
Vendor locked to one AI tool 100% portable — works with any MCP-compatible client
The AI never sees your full database. Aethos converts queries into 768-dimensional vectors, searches Supabase for the closest matches by cosine similarity, and returns only the relevant facts — fast, private, and precise.
This guide covers every step from zero to a fully working Aethos Memory setup on Windows 10 or 11.
Before starting, make sure you have the following installed:
