Decision brief
semtools is a Rust-based tool that provides command-line capabilities for semantic searching and parsing documents. It leverages embeddings and static embedding techniques to offer robust data retrieval functionalities.
Good fit when
- - When you require fast, statically typed document and search functionality via the command line built in Rust.
- - For teams or projects already integrated with Rust-based technologies, semtools offers a seamless addition due to its language compatibility.
Avoid when
- - If your workflow does not frequently involve command-line operations for managing search capabilities on documents, as semtools is explicitly designed for such usage.
- - When there's no plan or necessity to integrate with Rust-based ecosystems, since semtools might require additional effort in setting up a compatible environment.
- Pricing:
- freemium - Freely available under the MIT license, with possible premium features not covered by open-source.

Install:
You can install semtools via npm:
npm i -g @llamaindex/semtools
Or via cargo:
---
# install entire crate
cargo install semtools
---
# install only select features
cargo install semtools --no-default-features --features=parse
Note: Installing from npm builds the Rust binaries locally during install if a prebuilt binary is not available, which requires Rust and Cargo to be available in your environment. Install from rustup if needed: https://www.rust-lang.org/tools/install.
