Memory

Memory is how your task maintains context and remembers what has been discussed, decided, and produced. It enables truly resumable work — you can come back after days and pick up where you left off.

Two Components

OpenViber’s memory system has two parts:

1. Task Memory (Human-Readable)

Each task maintains its own memory:

Notes — Important decisions and context (memory.md)
Daily logs — Rolling record of work (memory/YYYY-MM-DD.md)

Location: ~/.openviber/vibers/{id}/

You can browse, edit, and version-control these files like any project.

Working Data (Spaces)

The things tasks produce and work on live in spaces:

Plans — Current tasks and goals
Artifacts — Files, documents, code produced

Location: ~/openviber_spaces/ (or any directory the task is pointed at)

2. Semantic Memory (AI-Optimized)

The semantic memory is how agents quickly find relevant context:

Meaning-based retrieval — Find information by concept, not just keywords
Summarized knowledge — Key decisions without overwhelming detail
Fast lookups — Optimized for efficient reasoning

When an agent needs to remember “What did we decide about the database schema?”, it queries semantic memory to get a focused, relevant response.

How They Work Together

You ask the agent to continue work on a feature
The agent queries semantic memory for relevant context
Semantic memory points to specific files in the space
The agent reads those files for full detail
Work continues with full context

Why This Matters

Without memory:

“Write chapter 3 of the documentation” Agent: “What documentation? What’s in chapters 1-2?”

With memory:

“Write chapter 3 of the documentation” Agent: “Based on chapters 1-2 about architecture and setup, chapter 3 should cover…”

Local by Default

All memory lives on your machine at ~/.openviber/vibers/{id}/. This means:

Privacy — Your context never leaves your machine
Persistence — Switching chat apps doesn’t lose context
Transparency — You can see exactly what the task remembers
Isolation — Each task has independent memory
