What problem does it solve?

This Skill provides a persistent memory system, allowing the AI to recall past information, user preferences, and session details across different interactions, preventing repetitive questions and ensuring continuity.

Core Features & Use Cases

  • Long-Term Memory: Stores curated facts, preferences, and decisions in MEMORY.md.
  • Daily Logs: Appends session notes and progress to timestamped daily files.
  • Search: Enables full-text search across all stored memory.
  • Use Case: After a user explains their preferred coding style, the AI can use pi-memory to store this preference and apply it to future code generation tasks without needing to be reminded.

Quick Start

Use the pi-memory skill to write "Completed the user authentication module." to the daily log.

FAQPage Schema
How do I give an AI persistent memory across different sessions?

You can give an AI persistent memory across sessions by using a file-based system that stores long-term facts in MEMORY.md. This allows the agent to retain context and recall user preferences without repetitive questions.

What is the best way to retain session context and long-term knowledge for AI agents?

The best way to retain session context is to append daily notes to timestamped files and curated facts to a central markdown file. This enables full-text search and knowledge persistence across interactions.

How do I store user preferences so an AI can recall them later?

To store user preferences for later recall, write them to a long-term memory markdown file. The AI can then search this file to apply your preferences to future tasks automatically.

Can I search through past session logs and memory files?

Yes, you can search past session logs and memory files. The system provides full-text search capabilities across all stored daily logs and the main long-term memory file.

Does pi-memory require any external databases to manage knowledge?

No, pi-memory does not require external databases to manage knowledge. It uses a lightweight file-based system to store memory content directly in markdown files.
