Accordion

Accordion is a free and open-source tool designed to make the context window of AI agents transparent and manageable. The platform addresses the challenge of context window limitations, where an agent's memory can silently discard information as the window fills, leading to irreversible loss of detail or entire conversation turns. Accordion provides a visual representation of the agent's context as a list of sections, each corresponding to a turn, allowing users to see, fold, unfold, and pin any part of the context. This approach transforms the typically opaque process of memory compaction into an interactive map where nothing is permanently lost.

The tool enables users to shrink any section of the context window into a summary and expand it back to full detail instantly, as many times as needed. Folding and unfolding sections affect only what the agent sees, not the underlying data, ensuring that information remains accessible throughout long tasks. Pinning sections allows users to keep important parts of the context visible and protected from being discarded. Accordion's design aims to give users manual and automatic control over the agent's context, making the process of memory management visible and reversible, in contrast to the default behavior where information loss is both invisible and permanent.

Accordion is available as a downloadable application for macOS (both Apple silicon and Intel), Windows, and Linux. The platform is offered free of charge and is open source, with its source code accessible via GitHub. It is positioned as a debugging and thinking tool for those working with AI agents, particularly in scenarios where understanding and controlling the agent's memory is critical. The tool does not act as a memory store but provides a dynamic view into the agent's context, allowing users to interact with and steer the memory window effectively.
