The Unix command ecosystem has received a groundbreaking boost with the introduction of Smartcat (sc), a tool that integrates advanced language models directly into the terminal. Designed for power users, Smartcat enables the automation and optimization of complex tasks through interaction with language model APIs while adhering to the minimalist and modular philosophy of Unix.
A New Era for Terminal Users
Smartcat is not just another tool for viewing or processing text in the terminal. Its unique approach combines the power of language models with the flexibility of Unix text streams, making it possible to:
- Seamlessly interact with language models: Integrate models such as OpenAI, Mistral, and Anthropic for advanced tasks like text generation, summarization, or test creation.
- Total configurability: Adjust settings like temperature, API, and prompt templates to suit user needs.
- Conversation support: Extend conversations over multiple steps, ideal for iterative workflows.
- Dynamic context management: Use glob expressions to include relevant files as context in requests.
Key Features
- Code editing and refactoring: By integrating with editors like Vim, users can select blocks of code, process them with Smartcat, and receive optimized results directly in their editor.
- Automating repetitive tasks: Through custom prompt templates, recurring tasks like translations, summaries, or test generation can be simplified.
- Enhanced context management: Users can provide multiple files as context, allowing models to generate more accurate responses.
For instance, commands like sc "translate this to Spanish" -c main.py
allow automatic translation of code file content while preserving its structure.
Integration with Editors
Smartcat simplifies interaction with editors like Vim and Helix, enabling commands to be executed directly from the editor to transform or process selected text. This results in an efficient workflow that combines the power of language models with traditional editing tools.
In Vim, for example, the command :'<,'>!sc "translate to German"
overwrites the current selection with the processed result from the model.

Installation and Configuration
Installing Smartcat is straightforward and supports multiple methods, including Cargo for Rust users and precompiled binaries. On first run, users are guided through basic setup, which includes:
- API configuration: Defining access keys for APIs like OpenAI, Anthropic, or a local server like Ollama.
- Prompt templates: Creating custom templates for specific tasks.
- Managed conversations: Saving and retrieving conversations for iterative workflows.
Basic Configuration Example:
[default]
api = "openai"
model = "gpt-4"
messages = [
{role = "system", content = "You are an expert programmer. Only provide the requested result."}
]
Practical Use Cases
Smartcat is useful for both developers and casual users looking to harness language models. Some notable use cases include:
- Summarizing code changes:
git diff | sc "summarize the changes"
- Quick translations:
cat readme.md | sc "translate to French" >> readme_fr.md
- Test generation:
sc "write pytest tests for this function" -c main.py
Why Smartcat Stands Out
Unlike similar tools, Smartcat focuses on deep integration with the Unix ecosystem, allowing users to maintain traditional workflows while leveraging advanced language model capabilities.
Its modular and highly configurable approach makes it an essential tool for those seeking to combine power, simplicity, and flexibility in the terminal.
Conclusion
Smartcat redefines how users interact with language models in the terminal, merging the best of Unix philosophy with modern artificial intelligence. From developers to analysts, this tool promises to transform workflows and maximize productivity.
