Web pages, documents, podcasts, and videos can be difficult to save, read, and search later. ReaderView transforms them into clean, distraction-free articles so you can focus on what matters. Save content for later, read offline, highlight important passages, and quickly find them again. ReaderView works with: - Web articles and blog posts - PDF documents, including images, tables, and mathematical formulas - Word documents and text files - Apple Podcasts and Spotify podcast episodes - YouTube videos - Vimeo and Dailymotion videos - X/Twitter posts, long-form articles, and videos TRANSCRIPTS THAT FEEL LIKE ARTICLES ReaderView looks for publisher-provided captions before generating a transcript, giving you faster and more accurate results whenever captions are available. With media transcripts, you can: - Read while listening or watching - Tap a word or timestamp to jump to that moment - Follow synchronized highlighting and automatic scrolling - Navigate with source-provided or automatically generated chapters - Play, pause, seek, and adjust playback speed - Show or hide videos for a distraction-free reading experience - Keep videos visible while scrolling when shown - Cancel queued transcriptions - Download source media when available READ, ORGANIZE, AND FIND EVERYTHING - Open a clean Reader View with a single tap - Listen with high-quality voices that work offline - Save articles and images for offline reading - Highlight passages and add notes - Search across your entire library - Find text within individual articles - Organize articles into folders - Sync across devices with iCloud - Find saved articles using Spotlight - Read comfortably with Dark Mode and Auto-Scroll - Support for Asian and right-to-left languages, including Arabic and Hebrew COPY, SHARE, AND EXPORT Export articles as plain text, Markdown, HTML, WebVTT, or PDF. You can also copy or share the original link. WebVTT is available for timestamped media transcripts. Share content with ReaderView from Safari, Apple News, X/Twitter, Feedly, YouTube, Apple Podcasts, Spotify, Word, and many other apps. When captions are unavailable, automatic on-device transcription for podcasts and X/Twitter videos requires iOS 26 or later. Have feedback or ideas? Contact laurent@appblit.com. If ReaderView helps you, an App Store review would mean a lot.

DoCube is a multi-format reader and personal knowledge base built for deep reading. Bring PDFs, EPUBs, local videos, web snapshots, Markdown, and organized scanned documents into one library. Annotate, link, search, translate, export, and review while you read or watch. Your materials are not merely stored—they gradually become knowledge you can retrieve, connect, and remember. 【Deep Reading Across Formats】 DoCube supports PDFs, EPUBs, local videos, offline webpages, Markdown, and parsed documents. Whether you work with research papers, ebooks, web articles, course videos, lectures, interviews, or your own Markdown notes, you can read, watch, and manage them together in DoCube. 【Deep Study for Video】 Import local videos and study courses, lectures, and interviews as deeply as documents. DoCube can read embedded subtitles and, on supported devices, generate subtitles for videos that do not have them. Search subtitles; switch between original, translated, and bilingual views; annotate subtitles; use chapter outlines, playback speeds, and A/B looping. Open a search result, annotation, or chapter to return to the exact moment, turning video into knowledge you can retrieve, connect, and review. 【Multi-Tab Reading】 Open multiple documents and videos in tabs, just like a browser, and switch quickly between materials. Read a paper, compare references, watch a course, or return to where you left off without losing context. 【Annotations and Notes in Context】 Use highlights, underlines, strikethroughs, quotations, links, and Markdown notes directly on source text or at a precise location in video subtitles. Your thinking stays connected to its context. 【Link Materials Together】 DoCube can link an annotation in a document or video to a precise location in another resource. Connect scattered chapters, paragraphs, webpages, video clips, and notes into your own paths through knowledge. 【Search What You Have Read and Watched】 Search not only titles and body text, but also video subtitles, highlights, quotations, links, notes, and cards. Anything you have read, watched, marked, or written can help you find the right material again. 【Keep Reading in Other Languages】 Translate selected text while reading. Some document types support full-document translation and translated exports, while videos support subtitle translation and original, translated, or bilingual display. Read foreign papers, webpages, ebooks, and course videos without constantly switching tools. 【From Annotation to Review】 Turn important content from documents and videos into review cards. Flip cards, mask cards, and review plans bring what you have read and watched back at the right time, instead of letting it disappear after you finish. 【Export and Sync】 Export document content and translations to common formats, including bilingual versions. DoCube is available on iPhone, iPad, and Mac, with iCloud sync and local Wi-Fi transfer. Ideal for: - People who read research papers and professional materials - Learners organizing PDFs, EPUBs, webpages, Markdown, and videos - People who study long-term with course, lecture, and interview videos - Deep readers who want annotations, notes, and review in one loop - Anyone building a personal knowledge base instead of merely collecting files The free version manages up to 5 documents and lets you experience the core reading and knowledge-management workflow. Upgrade to Pro to remove the document limit and build an unrestricted personal library.
