Stash

Stash is a persistent memory service that lets AI tools remember a user's preferences, plans and useful details across conversations and across different tools. Instead of explaining a writing style, learning level or dietary preference again in every new chat, the user saves it once and a connected assistant can recall it later. It works through remote MCP connections. After signing in with Google, the user receives a personal memory URL and connects a compatible tool by following the setup guide in the console. The listed tools are Claude Desktop, Claude Code, Cursor, OpenCode and Replit, and several can share the same memory, so context follows the user when they switch. Stash gives a connected assistant the ability to save and recall memories, and how and when it does so depends on that tool, so the user typically starts by asking the assistant to remember something. Memory is private by default, and the user can ask the AI to inspect, update or remove what it holds. The site and console are available in English and Arabic, with light and dark themes. Stash is aimed at anyone who uses AI to write, learn, plan or work, and the site states that being a developer is not required, only a tool that supports remote MCP connections. The site says Stash is free to start with no credit card required. It publishes no other plans or prices.
