A custom silicon processor, shipped by a Scottish hi-fi company in 1988, was designed to check memory access types and bounds in hardware, perform garbage collection, and treat memory and disk as a unified persistent object store. This innovative technology is now buried in the silt at the bottom of the Forth and Clyde Canal.

Deja-vu is a zero-dependency binary that creates a memory layer for coding agents, allowing users to search through extensive conversation histories generated by Claude Code, Codex, and opencode. It features a rapid search capability and a recall tool that enables agents to reference past solutions efficiently.

Stash is a cognitive layer that enables AI to retain memory across sessions, allowing for continuous learning and interaction. It differentiates between personal memory and project-specific knowledge, enhancing the AI's ability to provide personalized experiences.

Claude allows users to import preferences and context from other AI providers, enabling a seamless transition without starting over. Memory functionality is available on all paid plans and can be set up in under a minute.

Wax is a memory layer designed for on-device AI agents, replacing complex retrieval-augmented generation (RAG) pipelines with a single-file, serverless solution. It allows users to create a memory file, store information, and recall it efficiently without the need for additional infrastructure.
