It also includes Quillo Ai, which answers questions about documents, summarizes content, and cites page references by text or voice. The tool runs on Android, iPhone, and the web, with a single account syncing your library across devices. ### Review Quillo approaches document interaction from a listening-first angle, which sets it apart from editors that assume you'll be staring at the screen. The app combines a text-to-speech reader with an AI question-answering layer, plus a set of PDF utilities. This review examines what's currently shipped, how the features work together, and where the tool fits-or doesn't. #### Key Features - **Natural-voice reading with sentence highlighting.** Quillo reads documents aloud and visually highlights each sentence as it's spoken. The cloud voice runs on Gemini, and the maker describes it as calm and human-sounding. - **Quillo Ai for document Q&A.** You can ask questions about an open document and receive answers that cite specific pages. The AI also summarizes and, as of a recent update, generates exam papers with answer keys from notes or book chapters. - **Voice-first navigation.** The app was designed so blind and low-vision users can operate it by speaking. When you ask a question mid-reading, playback pauses on the current sentence and resumes from that exact spot afterward. - **Built-in PDF tools.** Merge, split, compress, convert, sign, stamp, watermark, and page numbering are available at no cost. On the web, these tools process files locally in the browser and do not store them on Quillo's servers. - **Document scanning and cross-device sync.** The app scans paper documents into PDFs. Your library syncs through your own Google Drive folder, meaning files stay in your Google account rather than on Quillo's servers. #### Pricing and Value Everything except the cloud voice and Quillo Ai is free. The PDF tools, scanning, and local playback carry no charge. New accounts receive 10 minutes of cloud voice and 10 pages of Quillo Ai as a one-time gift. The maker has not published ongoing pricing for cloud voice minutes or additional Quillo Ai pages beyond this initial allocation, so the long-term cost structure is not yet defined. #### Pros - Playback pauses and resumes precisely where you left off, even after interrupting with a spoken question. - PDF utilities run locally in the browser on the web version, keeping files off external servers. - The same account works across Android, iPhone, and web, with library sync through your own Google Drive. - Quillo Ai cites page references in its answers rather than giving unanchored responses. - Voice-first design makes the full app operable without looking at the screen. #### Cons - Quillo Ai currently answers in Turkish, which limits its utility for users who need responses in other languages. - Ongoing pricing for cloud voice and AI pages after the free allotment remains unannounced, making it hard to evaluate long-term cost. - The tool is not well suited for users who primarily need deep document editing or formatting-its strengths are reading and light PDF manipulation, not layout control or advanced composition. Quillo fits a specific workflow: people who consume documents by ear during commutes, walks, or other screen-off moments, and who occasionally need to query those documents or run quick PDF operations. Students reviewing notes, professionals processing contracts, and blind or low-vision users who want voice-driven navigation are the most natural matches. Anyone whose work centers on heavy document authoring or who needs AI responses in languages beyond Turkish will find the current feature set incomplete for their needs. --- This is the Markdown form of https://completeaitraining.com/ai-tools/quillo/.
