    # Auto-Draft: 文献整理辅助工具
    
    本Demo提供对[Auto-Draft](https://github.com/CCCBora/auto-draft)的auto_draft功能的测试。通过输入想要生成的论文名称（比如Playing atari with deep reinforcement learning)，即可由AI辅助生成论文模板.    
    
    ***2023-05-03 Update***: 在公开版本中为大家提供了输入OpenAI API Key的地址, 如果有GPT-4的API KEY的话可以在这里体验! 
    在这个Huggingface Organization里也提供一定额度的免费体验： [AUTO-ACADEMIC](https://huggingface.co/organizations/auto-academic/share/HPjgazDSlkwLNCWKiAiZoYtXaJIatkWDYM).
    如果有更多想法和建议欢迎加入QQ群里交流, 如果我在Space里更新了Key我会第一时间通知大家. 群号: ***249738228***.  
    
    ## 用法
    
    输入想要生成的论文名称（比如Playing Atari with Deep Reinforcement Learning), 点击Submit, 等待大概十分钟, 下载.zip格式的输出，在Overleaf上编译浏览.
