You upload a PDF, EPUB or text file, or paste a URL — the tool also accepts YouTube links and podcast episodes — and the service preprocesses the content so you can start asking questions even while the full summary is still being generated. Every response is grounded in the source: the app returns detailed references pointing to the passages it used, so you can verify what it claims rather than trusting a black box. The product leans heavily on a playful brand voice (the site jokes that PDF now stands for "Pretty Darn Fantastic"), but the underlying feature set is practical. Document preprocessing scales with file size, large books are handled with their full context, and the Q&A pipeline is described as tested against benchmarks from organisations including Google and Stanford. It also supports multiple languages, responding in the language of your question. Privacy is a stated priority. Documents are stored on encrypted databases, are never used to train external models, and the team says it purges data from third-party providers such as OpenAI on a weekly basis. Retention differs by plan: automatic deletion after one month on the entry tier, six months on the mid tier, and indefinite storage on the top tier unless you delete manually. You can also remove documents yourself at any time. The company contributes monthly to environmental charities through earth.fm and is part of the One Percent for the Planet network. **Pricing & Plans:** Freemium. There is a free tier you can start on without payment, and paid subscription tiers (referenced as Playful, Dynamic and Flagship) that raise document size limits and extend how long stored documents are retained. Check the site's pricing page for current amounts. - **Ask questions across formats:** Upload PDFs, EPUB books, text files or paste a web article link, YouTube video or podcast episode and chat with the content in one interface. - **Answers with references:** Responses are backed by the passages they were drawn from, so you can check the source text instead of taking an answer on faith. - **Full-context book summarisation:** Large documents are summarised with their whole context in mind, which matters for ebooks and lengthy reports. - **Multilingual Q&A:** The system supports many languages and replies in the language of your question. - **Exportable answers:** AI responses can be exported for reports, research notes or your own record keeping. **Strengths:** Handles PDFs, ebooks, web pages, YouTube videos and podcasts in one tool; Answers include source references, which makes verification straightforward; Free tier available to test the workflow before paying; Clear, documented data-retention and deletion policies **Limitations:** Preprocessing time grows with document size, so very large files are not instant; Free tier caps file size, which can block huge books until you upgrade [Profile (Markdown)](https://openaitools.app/tool/aipdf.md) ## Gauth Gauth is a study app that turns homework problems into teaching moments. A student photographs a question or pastes it into the web calculator, and the AI returns a structured solution that walks through the reasoning instead of just giving the final number. Coverage is deliberately broad: maths and calculus, statistics, physics, chemistry, biology, economics, literature, business, writing, social science and general-purpose subjects, which makes it useful across very different curricula rather than only for algebra drills. The platform pairs two layers of help. The AI layer answers quickly and free of charge for a limited number of questions, with detailed step-by-step explanations and tips on the concepts behind each step. On top of that sits a tutor service that connects students to real verified tutors around the clock; the company advertises tens of thousands of experts, high satisfaction rates, fast turnaround on hard problems and access to a large question knowledge base. Gauth also offers an Academy section with courses and a newer Gauth Atlas experience that turns subjects into explorable visual maps grounded in cited sources. Gauth is available on the web and as a mobile app on both iOS and Android, where it has a large review base. It follows a freemium model: a free tier covers everyday questions, while Gauth AI Pro unlocks unlimited answers and premium features via a free trial followed by a paid subscription. Exact plan prices and trial conditions should be confirmed on the official site. **Pricing & Plans:** Freemium. A free tier answers a limited number of questions, and Gauth AI Pro offers unlimited answers and premium features, typically starting with a free trial before a paid subscription. Check the official site for current prices and trial terms. - **Photo-based question solving:** Upload or paste a homework question and receive an answer in seconds, covering maths, sciences, business, writing and social sciences. - **Step-by-step explanations:** Solutions break the problem into clear steps with reasoning and conceptual tips, so students learn the method rather than only the result. - **24/7 human tutor service:** When AI output is not enough, students can escalate to verified human tutors for personalised guidance, including help with advanced problems. - **Gauth Atlas visual learning:** An explorable visual map turns a subject into zoomable layers of related ideas, with each image traced back to a real source. - **Cross-platform access:** Use Gauth in the browser or through the iOS and Android apps, with an Academy area for structured courses and a large study-resource library. **Strengths:** Works across a very wide range of subjects, not just mathematics; Step-by-step explanations focus on understanding rather than answer copying; Human tutors are available around the clock for problems the AI cannot resolve; Free tier plus mobile apps on iOS and Android make it easy to try **Limitations:** Unlimited answers and premium features require the paid Gauth AI Pro subscription; AI-generated solutions can still contain mistakes on unusual or ambiguous problems, so they should be checked; Reliance on instant answers can undermine learning if used without attempting the problem first [Profile (Markdown)](https://openaitools.app/tool/gauthmath-com.md) ## Frequently Asked Questions ### How do aiPDF and Gauth compare in monthly traffic? aiPDF has 3,816 monthly visits, while Gauth has 7,164,627.
