MemoryMesh, explained for beginners

MemoryMesh is long-term memory for AI agents; notes that look like known injection commands are quarantined and never recalled.

What it is

AI agents forget everything between conversations unless something remembers for them. MemoryMesh stores notes for an agent ("Acme's renewal is March 1") and finds them again with a proven search method (BM25, the ranking behind classic search engines), with no AI model involved.

Memory is also an attack route: a malicious email saved to memory today can give the agent orders next week. MemoryMesh screens every note when it is stored. Text that matches known injection patterns, like "ignore all previous instructions" or "you are now...", is quarantined: kept for review, but never returned by search.

An everyday comparison

A mailroom that files your letters and puts anything that looks like a known scam in a locked tray.

How it works, in 4 steps

1. The agent stores a note.
2. The note is screened against injection patterns.
3. Normal notes are active; matches are quarantined.
4. Search returns active notes only, ranked by relevance.
