DocDigest — Offline Summarizer

Read less. Know more. DocDigest is an offline PDF summarizer: it turns any PDF, Word document, EPUB or text file into a clear summary — using a fast built-in engine or a fully offline AI summarizer, entirely on your phone. No account, no cloud, no tracking. Your documents never leave the device, and summarizing keeps working in airplane mode. WHAT YOU GET • TL;DR — the whole document in a sentence or two • Key points — clean bullets, with page references on PDFs • Highlights — the standout quotes, verbatim • Ask this document — question the text and get grounded answers • Immersive reader — a distraction-free full-text view with progress • A searchable library — every summary you make, filed by folder and category WHO IT'S FOR • Students summarizing lecture notes, textbooks and PDFs before an exam • Researchers skimming papers to decide what deserves a full read • Professionals digesting reports, contracts and long policy documents • Readers pulling the key ideas out of articles and EPUB books • Anyone with more to read than there are hours in the day HOW IT SUMMARIZES • Fast extractive engine, built in — instant summaries on any phone, nothing to download, offline from the very first launch • Optional on-device AI models (Qwen, Gemma, Llama, Phi) — download one and get abstractive summaries written in the model's own words, still entirely offline • System AI — uses the AI built into your phone wherever it is available Pick the summary length that suits the document — brief, standard or detailed — and re-summarize anything with a different length or a different engine whenever you want. ONE SUMMARIZER FOR EVERYTHING YOU READ • Summarize PDF files — reports, papers, contracts, long manuals • Summarize Word documents without opening an office suite • Get a book summary from any EPUB before you commit the hours • Turn lecture notes and textbook chapters into clean study notes • Condense articles, essays and saved web pages in seconds PRIVATE BY ARCHITECTURE Most document summarizer apps upload your file to a server. DocDigest never uploads your documents: summarizing happens entirely on your device. The network is only used to download the AI models you choose, to verify Pro purchases and to send anonymous crash reports. No sign-up, no analytics, and no document ever leaves your device. Offline-only mode blocks even the model downloads. SUPPORTED FORMATS PDF · DOCX · EPUB · TXT · MD · CSV · HTML · RTF The app is available in 30+ languages, and it summarizes documents written in Latin, Cyrillic, Arabic, Devanagari, Chinese, Japanese and Korean scripts. Every document, distilled.
