AI research assistant
An AI research assistant for your own sources
Upload papers, reports and links and let Doxy read them for you. Ask questions, compare sources and get answers with citations you can verify.
Research grounded in your sources
A general chatbot draws on whatever it was trained on. Doxy is an AI research assistant that works from the sources you give it — papers, reports, books, web pages and transcripts — so its answers reflect your material, not the open internet.
Read faster, cite everything
Drop in a stack of PDFs and ask for the key findings, the methodology, or how two papers disagree. Doxy pulls the relevant passages and answers with citations, so this is document Q&A you can defend — every claim links back to the exact source.
Build a project library
Group everything for a topic into a project and Doxy treats it as one searchable knowledge base. Add a PDF, a website or a YouTube video, then chat across all your documents at once.
From reading to understanding
Beyond search, Doxy helps you make sense of what you collect — ask for summaries, explanations and comparisons, or use the built-in study toolsto quiz yourself. It's also a capable NotebookLM alternative.
Guides: research with AI
Want to go deeper before you start? Our guides cover the workflows this page describes, with concrete examples of prompts, project setups and the pitfalls to avoid. Read The Best AI Research Assistants in 2026 for an honest comparison of the tools in this space and where each one shines. Then see Q&A Over Your Documents With Citations to understand how cited answers work and why they matter for research you have to defend. And when a hundred-page report lands on your desk, our guide to summarizing long PDFs shows how to distill it without losing the details that matter — section by section, with follow-up questions to probe the parts a summary glosses over.
Frequently asked questions
What is an AI research assistant?+
An AI research assistant helps you read, search and question a body of sources. Doxy works from documents you upload and answers with citations back to the source.
What sources can it use?+
PDFs, Word, PowerPoint and Excel files, images, audio, HTML, CSV, ZIP and EPUB, plus any web link or YouTube URL — grouped into projects you can question all at once.
Will it make things up?+
Doxy answers only from the sources you provide and shows the passages it used, so you can verify every claim instead of trusting an unsourced response.
Is it free to use?+
Yes. Doxy has a free plan with a monthly question allowance and a few uploads. Pro and Business plans raise the limits and add quizzes and practice exercises.
Can it compare multiple papers at once?+
Yes. Add several papers to one project and ask how they agree or disagree on a point — Doxy retrieves the relevant passages from each and answers across all of them, citing which document each claim came from.
Can it help me revise what I've read?+
Yes. On Pro and Business plans, Doxy can generate multiple-choice quizzes and open-ended practice exercises from your sources, so you can check how well you've absorbed a paper or report instead of just re-reading it.
