🧠 Echoe — A Second Brain Simulator

Ghost in the Machine 👻

What if your memories didn't just disappear into folders, forgotten notes, and old documents?

What if they could think, connect, and resurface when you need them?

Echoes is an AI-powered Second Brain Simulator built around Gemma 4. The idea is to create a searchable, interconnected memory system that doesn't simply store information but understands relationships between it.

👻 What does it do?

• Memory Ingestion: Collects notes, PDFs, conversations, research, and other personal information.
• Knowledge Graph: Connects people, concepts, events, facts, and ideas.
• Associative Recall: Retrieves memories through meaning and connections rather than just keywords.
• Memory Timeline: Revisits information based on when it happened.
• Contradiction Detection: Identifies conflicting information across stored memories.
• Dream Mode: An experimental feature that explores forgotten connections and discovers unexpected relationships between memories.

⚡ Why Open Source AI?

The idea behind Echoes is that your memories should belong to you.

By using an open-weight model like Gemma 4, the project aims to support local inference, private data processing, model customization, and independence from proprietary AI APIs.

Your personal knowledge shouldn't have to live on someone else's server.

Open models also make it possible to experiment with how AI processes, retrieves, and connects information without being locked into a single provider.

🛠️ Tech Direction

• AI Model: Gemma 4
• Foundation: Sproutpatch (fork-based development)
• Core Concept: Local AI + Knowledge Graph + Associative Memory
• Goal: A personal memory system accessible across laptop and phone.

💭 The Bigger Idea

We spend years collecting information but very little time reconnecting with it.

Echoes explores the possibility of an AI that doesn't just answer questions but helps you rediscover things you've forgotten.

A second brain that never truly forgets.

Because sometimes, the most interesting ghost in the machine is a memory you thought was gone.
