Show HN: Callimachus – Local search across your AI coding-agent history (github.com)

Callimachus, a new tool designed for developers, enables local indexing and searching of coding-agent interactions across 11 different platforms, including Claude Code and Codex. This software combines various capabilities such as hybrid keyword and semantic search using a local SQLite database and on-device semantic similarity, ensuring that all data remains on the user's machine. The tool also supports features like filtering by source and project, extracting TODOs, and automatic knowledge distillation, allowing users to efficiently track decisions and code-related discussions. The significance of Callimachus lies in its local-first approach, enhancing privacy and security for developers by keeping their historical data in-house, with minimal exposure to external servers. By facilitating seamless integration between various AI coding agents and organizing project memories, it streamlines collaboration and understanding of past work, which can be especially beneficial in large or ongoing projects. With support for extensions like a VS Code plugin and a robust command-line interface (CLI), Callimachus not only organizes knowledge but also empowers developers to leverage their coding history effectively, fostering a more productive and informed AI development environment.
