# ButlerBrain

Persistent memory layer with semantic search across notes

Listed in ChatGPT

[ChatGPT listing](https://chatgpt.com/plugins/butlerbrain?open_in_app) [butlerbrain.ai](https://butlerbrain.ai)

Overview

## What ButlerBrain does

ButlerBrain adds a memory store that sits alongside an AI assistant and keeps information between conversations. Thoughts and notes can be saved, documents uploaded, and web pages crawled into the same store, with every entry searchable by meaning rather than exact keyword match.

The record also lists calendar event handling and native connections to other tools, Obsidian among them. Memories written through one assistant remain reachable from another, so the store is not tied to a single chat client.

Example prompts in the listing point at a domestic use case: recording that a child's soccer practice moved to Thursday at 4pm, then asking later what is known about that person across every stored memory.

### Who it is for

People who want facts from past conversations to persist across different AI assistants rather than reset each session.

### What stands out

The memory store is written and read from multiple assistants, not confined to one chat product.

Availability

## Where ButlerBrain is listed

ButlerBrain is listed in the ChatGPT apps directory only. ButlerBrain has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
