Store description excerpt
SAPIENTIA is a tool to search, read, and listen to your PDFs - from papers and dictionaries to everyday reading. Find with cross-PDF search, read in the reader, and listen with on-device text-to-speech. The AI exploration that breaks research silos is here too. [Instant search across thousands of pages] Import a PDF and full-text fuzzy search becomes available. Hiragana, katakana, full and half width are unified; Levenshtein distance allows for typos. Even a dictionary of thousands of pages returns results almost instantly. Two-phase (exact then fuzzy), Japanese normalization, context snippets, seven highlight styles. [Peripheral Exploration] AI extracts key phrases and generates cards in two ranges: Mid-range (adjacent fields) and Far-range (distant domains, including folk knowledge and crafts across cultures). Paper lookup runs in Japanese, English, and Chinese in parallel against Semantic Scholar, so even a Japanese keyword pulls in the right papers; otherwise it falls back to Google Scholar or Web search. [Multilingual Paper Search] A keyword in any language is auto-translated and searched across CiNii, J-STAGE, Crossref, arXiv, and Semantic Scholar at once. Result titles are shown in your UI language. [AI Summary - on-device when possible] Summarize the context around a hit, or all hits at once. On Apple Intelligence devices (iPhone 15 Pro and later) it runs fully on-device - PDF content never leaves your device. Otherwise it falls back to the Gemini API. [Write memos and return to the source] Leave a memo on any page. v4.0 introduces a dedicated Memos tab where every memo can be browsed and searched together. One tap returns you to the source PDF and page. [Read - resume, bookmarks, cross-PDF hits (v4.1+)] The app remembers the page (and read-aloud position) you closed on, so you can resume. Bookmark and jump from the bottom bar, and move through pages with the slider. After searching, step through exact-match hits one by one - across other PDFs too - each auto-highlighted. [Listen - on-device text-to-speech (v4.2)] Have your pages read aloud, continuing automatically to the next page. Adjustable speed, sleep timer (up to 2 hours), pages-to-read limit (up to 100), resume mid-sentence, an "extend" prompt when time/pages run out (tap or shake to continue), and a remaining countdown. Plays in the background and on the lock screen, with controls and extend. Runs on-device; text is never sent externally. Tip: add a high-quality voice in iOS Settings for a more natural sound. [Capture pages directly] No PDF? Photograph book pages and we OCR them via Apple Live Text, including vertical Japanese. Capture an entire dictionary or specialized book. [All major cloud providers] Import PDFs from iCloud Drive, Google Drive, OneDrive, and Dropbox. [Multilingual UI and translation] UI in Japanese, English, and Chinese. Tap to translate selected text; on Apple Intelligence devices, translation runs on-device too. [Pro features (14-day
