用日常语言提问,答案来自你上传的文件本身,而不是来自开放的网页搜索。
长篇报告被压缩成保留核心论点的简报,也可以要求只针对某一节继续细化。
上传某一语言的文档并翻译成另一种语言,原文语言与提问语言互不影响。
阅读区与对话区并排显示,可以随时拿原文核对 AI 给出的每一条结论。
扫描件与拍照页面先经过 OCR 文字识别,之后可与普通文档一样摘要、搜索与提问。
免费 AI PDF 阅读器把「读文档」和「问文档」放在同一个屏幕里。上传文件后,AI 会通读全文并给出要点摘要,而原始 PDF 会一直留在旁边,你可以随时对照原文核查 AI 说的每一句话。这种并排布局是它和常见「上传后只给你一段摘要」工具最明显的区别。
它支持 PDF 之外的多类文档:DOCX、TXT、PPTX、EPUB 和 FB2 都可以直接上传,单个文件上限 30 MB。提问语言与文档语言彼此独立,所以你可以读一份英文合同,用中文提问。没有可选文字的扫描页会先经过 OCR 识别,之后这类文件就能像普通文档一样被摘要与检索。
站点明确表示完全免费,没有付费方案、订阅或付款页面,也不需要注册账号。无需登录和没有每日文档数量上限这一点,在学生、研究人员和需要快速处理合同与报告的专业人士中尤其有吸引力。
把一份长报告压缩成保留核心论点的简报,再回到对话里追问没看懂的部分。
用自己的语言快速浏览方法与结论,几分钟内判断是否值得精读全文。
把合同、提案与报告缩减到真正需要行动的部分,并通过对话定位具体条款或数字。
读一种语言的文档,用另一种语言提问,并让 AI 把关键段落翻译过来。
