Quillo is a document app for Android, iPhone and the web. You can use it to read, listen to, sign and manage PDFs and other files. It reads documents aloud in natural Turkish voices, scans paper into searchable PDFs, and includes 21 free PDF tools that run on your device. Its assistant, Quillo Ai, summarizes files, answers questions, drafts letters and builds exams. It suits students, teachers, low-vision users and anyone who handles contracts or receipts.

• Listen to Documents: Quillo reads your files aloud sentence by sentence in natural Turkish voices. You get speed control, a sleep timer and audio export, and playback switches to your device voice when your cloud minutes run out.
• Quillo Ai Assistant: Ask it to summarize documents, answer questions, research the web with sources, make study cards or write letters. You can also talk to it by voice.
• Free PDF Toolkit: Merge, split, compress, reorder, rotate, watermark, number pages, add or remove passwords, and convert to and from Word, JPG and PNG. There are no daily quotas, file size limits or watermarks, and files are processed on your device.
• Letterhead, Signature and Stamp: Apply your letterhead, add signatures, stamps and dates, then send the finished document straight back, for example over WhatsApp.
• Document Scanner: Edge detection, page straightening and shadow removal turn photos of paper into clean, searchable PDFs.
• AI Exam Builder: Create exams from notes, book chapters or sample question photos with multiple-choice, true/false, fill-in-the-blank, matching, short-answer, open-ended and picture questions, plus an answer key.
• Online Exams with Live Reports: Publish an exam as a link or QR code. Students join without an account, question order is shuffled for each student, scoring is automatic, and you can export results to Excel or Google Sheets.
• Offline Translation and Sync: Translate between 13 languages with a one-time offline language pack. Your library syncs across devices through a Quillo folder in your own Google Drive.

• Most Features Cost Nothing: All PDF tools, the scanner, signatures, translation and study cards are free with no account needed. You only pay for cloud voices and Quillo Ai.
• Private File Handling: The PDF tools process files on your device or in your browser instead of uploading them. Your library and exams are stored in your own Google Drive, not on Quillo's servers.
• Designed for Accessibility: The app was built from the start for visually impaired and low-vision users, with TalkBack and VoiceOver support and a listen-first experience.
• One Subscription Across Platforms: A single plan works on Android, iPhone and the web, on up to 5 devices.
• Clear AI Cost Estimates: The exam builder shows how many AI pages it will use before it runs, and instantly gradable questions are scored on your device at no AI cost.
• Many Tools in One App: Reading, listening, signing, scanning, annotating, translating and exam creation are all in one place, so you need fewer separate apps.

• Metered AI and Cloud Voice: Paid plans include a fixed monthly allowance (for example, 90 minutes of cloud voice and 40 AI pages on Pro monthly). Heavy users will need to buy extra packs, unlike unlimited-use competitors.
• Requires an Internet Connection for Cloud Features: Quillo AI and premium cloud voices need an internet connection. Users who work offline must rely on device voices and on-device tools.

• Listening to Long Documents: Commuters and low-vision users can load a contract, report or book chapter and listen to it in a natural Turkish voice. A sleep timer and speed control make long sessions easier.
• Signing and Returning Paperwork: A tenant or landlord can scan a lease, add a signature and stamp, apply a letterhead and send it back over WhatsApp, all from a phone without printing anything.
• Teacher Exam Preparation: A teacher can turn a textbook chapter into a printable exam with a school header and answer key. They can also publish it online with a QR code, watch live results and export scores to Google Sheets.
• Everyday PDF Tasks: Anyone can merge receipts, compress a file for email or convert a PDF to Word in the browser for free. There are no watermarks, and files are not uploaded.
• Asking Questions About Your Archive: Instead of digging through files, you can ask Quillo Ai about your stored documents. It can summarize them, find answers and draft a reply letter.
