Legal, law-enforcement and media teams upload recordings, documents and photos into a secure case workspace where Rev transcribes everything, answers questions across all files with citations, drafts documents and exports polished transcripts for court or publication. **價格與方案:** Contact for pricing. Rev offers a free trial with no credit card required, self-service AI transcription and captioning at published per-minute rates, and a public pricing calculator that estimates human and AI transcript, caption and subtitle costs. Legal and investigative platform plans are enterprise-oriented and quoted per organisation, while human transcription is priced by turnaround speed and audio length. - **Multi-file evidence analysis:** Upload recordings, reports, PDFs and photos into a single case, ask questions across every file and get answers cited back to the source. - **Document editor and drafting:** Turn findings into memos, outlines or motions inside Rev, edit inline and export straight to Word or PDF. - **Image analysis:** Flag inconsistencies across case photos automatically, with every finding linked to the exact image it came from. - **AI and human transcription:** Clean, searchable transcripts for body cam, calls and interviews, generated by AI in minutes or by humans at 99%+ accuracy, with inline editing and clipping. - **Captions, subtitles and developer API:** Captions and subtitles for video distribution and accessibility, plus a speech-to-text API for developers who want to build Rev's engine into their own products. **優勢:** Rare combination of AI speed and human-verified accuracy at 99%+ in one platform; Purpose-built legal and investigative workflow that cites every answer back to the source file; Broad format support: audio, video, Word, PDF and images handled in the same case workspace; Established trust with 2,000+ law firms and agencies, with SOC 2 Type II auditing **限制:** Human transcription and captions cost considerably more than pure DIY AI tools; The product has shifted heavily toward legal and investigative teams, so general creators may find the current framing intimidating; Very long files and specialised legal formats can still need manual review; Enterprise legal features and human services are quote-based, so pricing requires contacting sales [Profile (Markdown)](https://openaitools.app/tw/tool/rev.md) ## UBBLU UBBLU 圍繞一個簡單的承諾構建：少搜尋，多創造。它不把筆記當作需要分類和記憶的檔案櫃，而是當作一個可以隨時查詢的記憶。你在記錄時捕捉想法、靈感、會議筆記和關鍵資訊，讓應用在需要時負責回想。 它的結構刻意保持輕量。Notes 用於捕捉稍縱即逝的念頭，Cards 用於承載更長、更成型的想法並沉澱為更豐富的知識庫。標籤對筆記和卡片進行分類與關聯，讓相關內容保持連接；資料夾、置頂和提醒則讓最常用的內容觸手可及。核心功能是「Ask」，它橫跨筆記、卡片、資料夾和標籤：你提出問題，UBBLU 立即帶回相關資訊，因此你永遠不必再去尋找把它存在了哪裡。 UBBLU 還延伸到打字之外。你可以上傳文件、就其內容提問，並把洞察存回為筆記。把內容歸到某個標籤下，UBBLU 就能基於這些關聯材料生成詳細答案並呈現洞察。它面向那些重視創造而非搜尋的思考者——這是公司自己的定位。註冊免費，無需信用卡。請注意，UBBLU 目前自稱為純桌面端應用，行動版已宣布即將推出，因此在決定使用前請確認裝置支援。 **價格與方案:** 免費。UBBLU 提供免費註冊，其核心的 AI 驅動筆記與檢索體驗無需信用卡。 - **Ask 全庫搜尋:** 用自然語言提問，UBBLU 會從你的筆記、卡片、資料夾和標籤中取出答案，而無需你翻找。 - **筆記與結構化卡片:** 用 Notes 快速捕捉稍縱即逝的念頭，用結構化的 Cards 展開更長的想法並沉澱為知識庫。 - **標籤、資料夾、置頂與提醒:** 用標籤和資料夾整理，把常用內容置頂，並設定提醒，讓截止日期和跟進事項不再遺漏。 - **關聯發現與洞察:** UBBLU 會連接相關概念，並基於某個標籤下歸組的內容生成詳細答案與洞察。 - **上傳文件互動:** 上傳文件、就其提問，並把答案存為筆記以便日後檢索。 **優勢:** 基於提問的檢索免去了記住筆記存放位置的需要; 筆記、卡片和標籤的輕量結構易於上手; 文件上傳加問答，把用途擴展到打字之外; 免費註冊，無需信用卡 **限制:** 目前僅支援桌面端，行動應用仍標註為即將推出; 公開網站較為精簡，部分細節需要註冊後才能看到; 作為較新的產品，整合生態仍有成長空間; 記筆記習慣因人而異，更換工具有真實的學習成本 [Profile (Markdown)](https://openaitools.app/tw/tool/ubblu.md) ## 常見問題 ### Rev 與 UBBLU 的每月流量相比如何？ Rev 每月有 1,524,237 次造訪，而 UBBLU 有 2,794。流量估算反映受眾規模，並非產品品質。 ### 兩者的成長率相比如何？ Rev 的月增率為 -12.9%；UBBLU 為 +13.5%。 ### 價格相比如何？ Rev：需聯絡報價。Contact for pricing.
