Download pre-built binaries for macOS, Linux, and Windows from [GitHub Releases](https://github.com/sigoden/aichat/releases), extract them, and add the `aichat` binary to your `$PATH`.
## Features
### Multi-Providers
Integrate seamlessly with over 20 leading LLM providers through a unified interface. Supported providers include OpenAI, Claude, Gemini (Google AI Studio), Ollama, Groq, Azure-OpenAI, VertexAI, Bedrock, Github Models, Mistral, Deepseek, AI21, XAI Grok, Cohere, Perplexity, Cloudflare, OpenRouter, Ernie, Qianwen, Moonshot, ZhipuAI, Lingyiwanwu, MiniMax, Deepinfra, VoyageAI, any OpenAI-Compatible API provider.
### CMD Mode
Explore powerful command-line functionalities with AIChat's CMD mode.
### REPL Mode
Experience an interactive Chat-REPL with features like tab autocompletion, multi-line input support, history search, configurable keybindings, and custom REPL prompts.
### Shell Assistant
Elevate your command-line efficiency. Describe your tasks in natural language, and let AIChat transform them into precise shell commands. AIChat intelligently adjusts to your OS and shell environment.
### Multi-Form Input
Accept diverse input forms such as stdin, local files and directories, and remote URLs, allowing flexibility in data handling.
| Input | CMD | REPL |
| ----------------- | ------------------------------------ | -------------------------------- |
| CMD | `aichat hello` | |
| STDIN | `cat data.txt \| aichat` | |
| Last Reply | | `.file %%` |
| Local files | `aichat -f image.png -f data.txt` | `.file image.png data.txt` |
| Local directories | `aichat -f dir/` | `.file dir/` |
| Remote URLs | `aichat -f https://example.com` | `.file https://example.com` |
| External commands | ```aichat -f '`git diff`'``` | ```.file `git diff` ``` |
| Combine Inputs | `aichat -f dir/ -f data.txt explain` | `.file dir/ data.txt -- explain` |
### Role
Customize roles to tailor LLM behavior, enhancing interaction efficiency and boosting productivity.
> The role consists of a prompt and model configuration.
### Session
Maintain context-aware conversations through sessions, ensuring continuity in interactions.
> The left side uses a session, while the right side does not use a session.
### Macro
Streamline repetitive tasks by combining a series of REPL commands into a custom macro.
### RAG
Integrate external documents into your LLM conversations for more accurate and contextually relevant responses.
### Function Calling
Function calling supercharges LLMs by connecting them to external tools and data sources. This unlocks a world of possibilities, enabling LLMs to go beyond their core capabilities and tackle a wider range of tasks.
We have created a new repository [https://github.com/sigoden/llm-functions](https://github.com/sigoden/llm-functions) to help you make the most of this feature.
#### AI Tools
Integrate external tools to automate tasks, retrieve information, and perform actions directly within your workflow.
#### AI Agents (CLI version of OpenAI GPTs)
AI Agent = Instructions (Prompt) + Tools (Function Callings) + Documents (RAG).
### Local Server Capabilities
AIChat includes a lightweight built-in HTTP server for easy deployment.
