Don't just ask a PDF for an answer. See the source, question the wording, and make the document useful. NetPDF combines reading, editing, study, and optional on-device assistance in one focused workspace. **READ AND FIND WHAT MATTERS** - Import PDFs and move quickly through pages and document outlines. - Search text, select passages, highlight, and bookmark important sections. - Use Read Aloud with playback speed controls. - Extract text from supported scanned pages with on-device recognition. **ASK QUESTIONS, CHECK THE SOURCE** - Summarize documents and ask questions about their contents. - Ask about a specific page or explain selected text. - Inspect available source passages and page references. - Keep reading and using document tools even when the optional language model is unavailable. **YOUR DOCUMENT DESK** - Rotate, reorder, merge, and extract PDF pages. - Undo supported page operations. - Export a separate working copy while retaining the original. - Switch to a reflowed text view for comfortable reading. **NOTES THAT REMEMBER WHERE THEY CAME FROM** - Attach your own notes to source passages and pages. - Keep your interpretation separate from the document's words. - Reopen saved notes and jump back to the original page. - Use Source Recall to review what you remember, reveal the passage, and mark it for another look. **TOOLS FOR LEARNING AND EXPLAINING** - Compare extracted text across two PDFs. - Turn reviewed content into structured timelines, mind maps, diagrams, and takeaway cards. - Save or share supported visual results. - On compatible hardware, optional locally imported image-model resources can enable illustration generation; this feature requires separate setup. **WORK WITH CONTROL** - Many reading, editing, search, and study features work locally. - Optional reference tools are controlled separately. - Use appearance, accessibility, haptic, and sound preferences that suit your workflow. NetPDF helps you read actively: explore a document, verify where an idea came from, then return to the evidence when it matters. AI answers, extracted text, OCR, and comparisons can contain mistakes. Confirm important details against the original PDF. Illustrations are creative outputs, not evidence from a document.

Stop guessing which AI gives the right answer. OneAnswerAI sends your question to OpenAI, Google Gemini and Anthropic Claude at the same time and gives you back one answer, built by comparing the three. -- HOW IT WORKS -- Every model has different strengths and different blind spots. Alone, each gets things wrong in its own way; compared, they correct each other. OneAnswerAI does that work for you: no opening three apps and reading three answers. Choose how your answer is built: FUSION MODE The three answers are merged into one that keeps the best of each. The recommended mode when reliability matters. PICKING MODE Want one specific model? You choose which one answers. -- TRY IT FREE -- The free plan includes a few questions a day, answered by Gemini. Your first question gets the full fused answer of all three models, so you see the difference before you decide. -- WITH PRO -- - Answers fused from OpenAI, Gemini and Claude, 40 questions a day - See where the three models agree and where they do not, answer by answer - Ask a specific model for a second opinion on an answer - Attach photos, screenshots, charts and PDFs: the models read them - Photograph a receipt and the app extracts vendor, total, items and VAT - Web search when needed, for up-to-date answers - Create and edit images (account required, adults only) -- ALWAYS INCLUDED -- - Conversations stay saved: search them, rename them, pin them - Set your level and your instructions once, and they apply to every answer - If an answer does not convince you, report it from the chat - 7 languages: English, Italian, Spanish, French, German, Arabic, Chinese -- WHO IT IS FOR -- Students who want to check an assignment or a research paper before handing it in, and professionals who cannot trust the first answer that comes along.
