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, each with its page reference
• 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 doesn't have a server. The network is used exactly once per AI model, to download it; everything after that happens on your device. Offline-only mode blocks even that. No sign-up, no analytics, and no document ever leaves your phone.

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.
