Memoria is a todo board, a notebook, and a memory store for AI agents. Everything it saves goes into a Google Sheet in your own Drive. There is no database and nothing to sign up for. Log in with Google, and your tasks are rows in a spreadsheet you own.
Why a spreadsheet? Because it will still be readable in ten years, with or without this app. You can open it in Google Sheets and edit it there. The app can only see the files it created, nothing else in your Drive.
The real reason I built it: I wanted a place where an AI agent can leave something for me, and where I can leave something for it. Not a chat log, not a file lost in some repo. If you use claude.ai or Claude Code, add Memoria as a connector, sign in with Google, and your agent can read the board, add tasks, move them around and take notes. It works when the agent runs on a schedule too, without me around.
The hosted version is at memoria-board.vercel.app. The code is on GitHub, MIT, and runs on free tiers if you want your own copy.
