Skip the generic summary. Ask the specific question and get the specific answer, sourced from the page it came from.
Verify in one click
Citations on every answer mean you trust but verify. No wondering whether the AI made it up.

刚刚使用 PdfGPT 制作了一个故事，我正在工作，然后就炸掉了。我输入了访谈、报告和一个背景文件的短信文件夹。 它不仅仅是概括性的，它对照官方报告核对了访谈中的引文，并向我展示了一个关键的消息来源自相矛盾的地方。 我请它证实一项说法，并收回了最近的可信的参考资料，而没有混淆不清。 这是我使用的第一个真正尊重准确性的AI 工具。记者：这是一个工具。

如果你是一位博士生淹没在论文中，请尝试PdfGPT。我花了几个月时间试图手动整理我的文献评论。 PdfGPT 阅读所有东西！所有50篇！ 并将它们自动归类为主题，突出的矛盾，甚至发现我忘了的旧笔记重复引用。 记事功能 + 多文档聊天是疯狂的。 我可以问：“哪些文件与主要假设不一致？” 而且它提供了一个清晰、引述的答案。这将拯救我整个学期。
