Memory

ChatPharo includes an optional long-term memory subsystem that can store and retrieve “memory items” and inject relevant context into prompts.

What memory is used for

• Remember stable user preferences (e.g., style of explanations)
• Keep concise summaries of prior conversations
• Carry forward important corrections and decisions

Memory controls

Typical settings include:

• memoryEnabled
• memoryAutoSummarize
• memoryRetentionDays
• memoryMaxItems

How memory affects prompting

When enabled, ChatPharo retrieves relevant memory items for the current query and injects them near the top of the prompt as a dedicated context block.

This is designed to:

• avoid bloating the conversation history
• keep important long-term context available even after resets

Auto-summarization

When auto-summarize is enabled, ChatPharo can summarize conversations into memory (typically after resets/clears or at a natural conversation boundary).

Data model (conceptual)

• Memory store: collection of memory items
• Memory item fields: content, timestamp, tags/metadata, source type
