Amber

A hosted memory layer that runs over HTTP instead of stdio, which means zero local setup. It exposes 18 tools split between memory operations (store, search, list, delete), account management (login via PayPal OAuth, export data, cancel subscription), and feedback. The interesting bit is the retrieval stack: hybrid vector plus keyword search with reciprocal rank fusion, query expansion through LLM paraphrasing, and multi-variant embeddings where each fact gets stored four different ways. Processing happens async on Cloudflare Workers so storage never blocks your conversation. Sixty day free trial, then $2.99/month. Reach for this if you want your assistant to remember context across sessions without maintaining your own vector infrastructure or running local processes.
