About

What is semtools?

semtools is a high-performance command-line interface (CLI) tool designed for semantic search and document parsing. Built with Rust, it prioritizes speed and reliability for efficient document processing. Key functionalities include parsing various document formats like PDF, DOCX, and PPTX into markdown using the LlamaParse API, and performing local semantic keyword searches with multilingual embeddings and cosine similarity. The tool also features an AI agent for document-based question-answering, which can be configured with OpenAI or other OpenAI-compatible APIs. For large collections, semtools offers workspace management to accelerate search operations, including caching embeddings and handling document changes. Its Unix-friendly design ensures proper stdin/stdout handling, making it versatile for integration into existing workflows. Configuration is flexible, allowing settings via a unified JSON file, environment variables, or CLI arguments.

Best used for

Ideal for developers and data scientists who need to efficiently parse various document types, perform semantic searches over large text collections, and leverage AI agents for document-based question answering. Especially valuable for integrating advanced text processing into command-line workflows and building RAG systems.

FAQs

What API keys are required to use semtools?

The `parse` subcommand requires a LlamaParse API key for document parsing, which can be obtained for free. The `ask` subcommand requires an OpenAI API key for the AI agent's language model. Both can be set via config file, environment variables, or CLI arguments.

Can semtools perform semantic search locally without external APIs?

Yes, the `search` and `workspace` subcommands are designed to be local-only. They use multilingual embeddings and cosine similarity for local semantic keyword search, and workspace management for efficient retrieval over large collections without requiring external API calls for these specific functions.

How can I configure semtools for different use cases?

semtools uses a unified configuration file at `~/.semtools_config.json`, where you can set parameters for parsing and the AI agent. You can also override these settings using environment variables or directly via command-line arguments, providing flexible configuration options.
