Doxy
What Doxy is
Doxy is a web app for asking questions about documents and other source material. Upload files, group them into projects, and ask questions in plain language; answers cite the documents used so you can check them against the originals. Supported material includes PDFs, Word and PowerPoint files, Excel sheets, images, audio, HTML, CSV, ZIP and EPUB files, plus web links and YouTube URLs. For YouTube links, Doxy uses the video transcript as source material. It supports questions in many languages and answers in the question’s language where the source material allows. Pro and Business users can create multiple-choice quizzes with explanations and open-ended exercises from selected sources. The free plan allows 3 documents, 20 questions per month and files up to 10 MB. Pro costs $4.99 a month; Business costs $9.99 a month. An account is required. Doxy says documents are scoped to an account and project; its policy says document content and questions are sent to OpenAI for embeddings and answer generation, and API data is not used to train models.
