## About 🔎
Local Sage is an open-source stateful CLI for interacting with LLMs in shell-based workflows.

Featuring **live Markdown rendering with inline math conversion** for a *silky smooth* chatting experience. Designed to hook into any **OpenAI API endpoint**, and tested with local LLMs hosted via **llama.cpp**.

**Additional Features:**
- **Standard Output Rendering**: History is persistent and scrollable, even after exiting the CLI.

- **Standard Input Piping**: Pipe stdin directly into Local Sage from the command line or a script.\
  *Example*: `ps aux | localsage "What process is consuming the most memory?"`
- **Fancy Prompts**: Command completion, path completion, and in-memory history for a shell-native UX.
- **Website Scraping**: Scrape a website with a simple command, and attach it's contents to the current session.
- **Context-aware Attachment**: Attachments are replaced on re-attachment and can be purged from a session, restoring context.\
  *Note*: Entire directories can be attached at once. Attached website content can be purged from a session as well.
- **Automated Environment Context**: Your model sees your username, your OS name, and the contents of your current working directory.\
  *Note*: When changing the working directory with the `!cd` command, your model is aware. Environment context mutates.
- **Session Management**: Load, save, delete, reset, and summarize sessions.
- **Profile Management**: Save, delete, and switch model profiles.
- **Context & Throughput Monitoring**: Shown through a subtle status panel.
- **Built-in Markdown themes**: Customize your output with a variety of built-in Markdown themes. Available themes are listed [here](https://pygments.org/styles/).

## Compatibility 🔩
**Python 3.10** or later required.

The big three (**Linux, macOS,** and **Windows**) are all supported. Ensure your terminal emulator has relatively modern features. Alacritty works well. So does kitty and Ghostty.

You can use non-local models with Local Sage if desired. If you set an API key, the CLI will store it safely in your OS's built-in credential manager via **keyring**. Setting the `OPENAI_API_KEY` environment variable works as well, and overrides all other options.

Each release is automatically published to Docker Hub. You can view instructions for running the CLI in Docker [here](#docker-).

## Installation 💽
Install a Python package manager for your OS. Both [**uv**](https://github.com/astral-sh/uv) and [**pipx**](https://github.com/pypa/pipx) are highly recommended.

###### For `uv`, open your terminal and type:
```bash
uv tool install localsage
```
###### Or, for `pipx`, type:
```bash
pipx install localsage
```
Type **`localsage`** into your terminal to launch the CLI. Type **`!h`** to view command usage.

### Getting Started ✔️
Configuration is done entirely through interactive commands. You never have to touch a config file.
1. Configure a profile with `!profile add`. API endpoint format: `http://ipaddress:port/v1`.
2. Type `!profile switch` to switch to your new profile.
3. Use `!ctx` to set your context length.
4. (Optional) Set your own system prompt with `!prompt` or an API key with `!key`.

> [!TIP]
> If you press `tab` while at the main prompt, you can access a command completer for easy command use.

## Docker 🐋
**Pulling from Docker Hub and running the container:**
```bash
# Download the image
docker pull kyleg142/localsage

# Run the container, '-e OPENAI_API_KEY' is optional
docker run -it --rm \
  -v /pick/a/data/directory:/root/.local/share/LocalSage \
  -e OPENAI_API_KEY \
  kyleg142/localsage
```
> Piping is not supported when running Local Sage in a container.

### Notes on Networking
You may have to add specific options to your `docker run` command if you are running a non-containerized backend/API on the same machine.

**Local Linux**
1) Add `--network host` to your `docker run` options to allow the container to reach services on localhost.
2) Follow the [**Getting Started**](#getting-started-%EF%B8%8F) section above.

**Local Windows/Mac**
1) Add `--add-host=host.docker.internal:host-gateway` to your `docker run` options.
2) Run the container, type `!profile add` to create a new profile. Set the API endpoint to `http://host.docker.internal:8080/v1` when prompted.
3) Ensure your API endpoint (llama.cpp, vllm, etc.) is listening on `0.0.0.0:8080`.

## Display Notes 🖥️
Typing into the terminal while streaming is active may cause visual artifacting. Avoid typing into the terminal until the current generation finishes.

A monospaced Nerd font is **HIGHLY** recommended. It ensures that Markdown, math, and icons all align well on-screen. The root prompt uses a Nerd font chevron.

## Under the Hood 🛠️

#### Context-Aware Attachment
When a file (or directory) is attached to a session, a wrapper is applied to the contents before being appended to the session history. This wrapper enables attachment detection via regex, for file management.

If you re-attach a file, context consumption is massively reduced by removing the entry containing the file contents from the session history and then appending the new copy. You can also completely remove a file from a session via the `!purge` command, which restores context spent.

A similar wrapper is applied to website content. That means `!purge` can also be used to remove scraped website content from the conversation history.

#### Automated Environment Awareness
Your model is provided with basic environment context that mutates depending on the current working directory.

This is what your model can see...
```shell
[ENVIRONMENT CONTEXT]                        # Header
Current User: {USER_NAME}                    # Your username
Operating System: {system_info}              # Your operating system
Working Directory: {wd}                      # Current working directory, mutates when using !cd
Visible Files: {", ".join(files[:20])}       # Up to 20 visible file names, mutates when using !cd
Visible Directories: {", ".join(dirs[:20])}  # Up to 20 visible directory names, mutates when using !cd
```

#### Rendering & Streaming
At its core, Local Sage uses the **Rich** library combined with a custom math sanitizer to render live Markdown and readable inline math. Chunk processing is frame-synchronized to the refresh rate of a rich.live display, meaning that the entire rendering process occurs at a customizable interval. Effectively a hand-rolled, lightweight, synchronized rendering engine running right in your terminal.

You can adjust the refresh rate using the `!rate` command (30 FPS by default).

## Limitations 🛑
Once the live panel group fills the terminal viewport, real-time rendering cannot continue due to terminal constraints. By default, the Response panel consumes the Reasoning panel to conserve space (toggleable with the `!consume` command).

**This should only be noticeable on large responses that consume over an entire viewport's worth of vertical space.**

**Local Sage is text-only.** This limitation keeps Local Sage portable, lightweight, and backend-agnostic.

## Versioning 🔧
The project follows basic versioning:
- **1.0.x** - Minor patches consisting of bug fixes and tweaks
- **1.x.0** - Major patches consisting of large feature expansions or necessary refactors.

## License ⚖️
Local Sage is released under the [**MIT License**](https://opensource.org/license/mit).

## AI Use 🤖

I use AI for theory-crafting, code review, and snippet generation. For example, most of the regex seen in `math_sanitizer.py` was generated and tuned by iteratively prompting GPT 5.1 and then ran against a pytest suite to prevent regression. The architecture of Local Sage is written and tuned by hand, and all documentation you see here is written by hand as well. This is NOT a 'vibe-coded' project.

## Closing Notes 🫵
Local Sage is an **open-source, single-dev project** built purely for the love of the game. Please be kind!
