Built a free PDF toolkit solo (with AI help) — need feedback on the in-browser text editor before I keep pushing on it Been heads-down on this for a while: thepdftool.in Standard PDF stuff : merge, split, compress, convert, OCR — but most of the conversion tools run entirely client-side (WASM), so files never leave your browser for those. Built solo, leaned on AI tools for a good chunk of the code and debugging. The feature I care most about right now is an inline text editor :— click i

做了一个音视频转文字工具,支持 MP3/MP4、说话人识别和字幕导出 大家好,最近做了一个在线音视频转文字工具 ToText ,想发出来请大家体验一下,也听听 V 友的意见。 最开始做这个工具,是因为我自己在处理会议录音、访谈和视频内容时,发现单纯生成一大段文字并不太实用。转录完成后,通常还需要反复对照原始录音、修改错误、区分说话人,再整理摘要或字幕。 所以现在做成了一个相对完整的工作流: * 上传 MP3 、MP4 、M4A 、MOV 、WAV 、WebM 等音视频文件 * 自动识别语言并生成带时间戳的文字稿 * 支持说话人识别和说话人名称修改 * 点击文字片段可以跳转到对应的音视频位置 * 可以搜索、编辑和校对转录内容 * 自动生成摘要、会议纪要、章节和行动事项 * 支持导出 TXT 、DOCX 、PDF 、SRT 、VTT 、CSV 和 JSON 音频文件可以直接使用 [MP3 to Transcript]( https://totext.app/) 功能,比较适合播客、访谈、课程录音、会议和语音备忘录。 视频文件也使用同一个编辑器,通过

做了一个 MP4 转文字的小工具 最近自己做了一个 MP4 转文字的 AI 小工具,主要用于把视频快速转换成文本。 项目地址: https://mp4totext.ai/ 开发过程中发现,真正麻烦的并不是调用语音识别模型,而是视频格式兼容、音频提取、长视频处理以及异步任务这些细节。 目前还在持续优化,如果大家平时有视频转文字的需求,欢迎试试看。 也想听听大家对视频转写类工具还有哪些实际需求。
