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 to help you make the most of this feature.
AI Tools & MCP
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.
