You supply a PDF or link, and the system identifies the key ideas, then generates a conversational summary in which synthetic hosts explain, question and contextualise the content. The result sounds closer to a podcast segment than to a robotic text-to-speech read-out. Because it is an experiment rather than a finished commercial product, access has been handled through a waitlist and Google account sign-in, and the interface is intentionally minimal: an upload area, a library of your generated sessions, and a player. Output quality varies by source, with well-structured papers producing the most coherent discussions. The appeal is practical. Researchers, students and busy professionals can triage a stack of papers during a commute, and the generated conversations can be paused, resumed and sped up like any other audio. It is best treated as a comprehension aid that complements careful reading, not a replacement for it. **Pricing & Plans:** Free to use as a Google Labs experiment; you sign in with a Google account and no published subscription tiers exist for the tool itself. - **Document to audio discussion:** Upload a PDF or point the tool at a web article and receive a spoken back-and-forth between two AI hosts rather than a flat read-aloud. - **Two-voice conversational format:** Distinct synthetic voices take turns introducing, summarising and questioning the source material, which makes complex topics easier to follow. - **Focus on key ideas:** The system extracts the central arguments and findings instead of reading the document line by line, producing a shorter, digestible overview. - **Personal audio library:** Generated sessions are saved to your account so you can revisit, replay or continue listening where you left off. - **Google account sign-in:** Access is gated behind a standard Google login, and the experiment is labelled as such within Google Labs. **Strengths:** Turns dense PDFs into an easy, podcast-style listening experience; Conversational two-host format is more engaging than plain text-to-speech; Free to use as a Google Labs experiment; Generated audio is saved to a personal library for replay **Limitations:** Experimental status means features, access and availability can change without notice; Not every source document produces an equally coherent discussion; Requires a Google account and, at times, waitlist access; It summarises rather than reproduces the source, so citations and nuance can be lost [Profile (Markdown)](https://openaitools.app/tool/google-illuminate.md) ## OpenRead OpenRead is built for people who read a lot of research and need to make sense of it quickly. It indexes a very large body of scholarly literature — the site advertises access to over 300 million papers, with fresh papers arriving from thousands of journals — and layers AI on top so you can search by meaning, not just keywords. You can upload your own PDFs alongside the public corpus and build a personal research space. Beyond simple summarization, OpenRead focuses on synthesis. Paper Compare highlights where studies agree and where they contradict each other, Paper Q&A lets you interrogate a document, and a related-paper graph shows how ideas connect across the literature. An Espresso mode and note-taking tools support fast skimming and capture, while chat access to top-tier AI models handles diagram drawing, image editing and homework-style questions — the platform positions itself as picking the best model for each task. The service has a free tier and a Pro subscription, and it also runs a program that pays experts for contributing knowledge. It is aimed at researchers, analysts and students working across disciplines, including market research, competitive intelligence and policy analysis. **Pricing & Plans:** OpenRead uses a freemium model: a free tier for core search and reading, plus a Pro subscription that unlocks higher limits and advanced AI features. Contact the team for institutional or enterprise arrangements. - **Semantic paper search:** Search a corpus of hundreds of millions of papers by meaning, with new content indexed continuously from thousands of journals. - **Paper Q&A and Compare:** Ask questions of any paper and place multiple studies side by side to spot agreements, contradictions and the bigger picture. - **Related paper graph:** A visual graph maps how papers and concepts connect, helping you find adjacent work you would otherwise miss. - **Uploads, notes and workspace:** Upload your own PDFs, capture reading notes, and organize everything in a single research workspace. - **Multi-model AI tools:** Access top-tier models for chat, diagram drawing and image editing, with new models added as they ship. **Strengths:** Very large indexed corpus with continuously refreshed papers; Synthesis tools (Compare, Graph) go beyond basic summarization; Combines external literature search with your own uploads; Multi-model chat for tasks like diagrams and images **Limitations:** Advanced features and higher limits sit behind the Pro plan; A very broad feature set can take time to learn; Multi-model chat is a general assistant aid rather than a peer-review tool; No indication of full offline or self-hosted use [Profile (Markdown)](https://openaitools.app/tool/openread.md) ## Frequently Asked Questions ### How do Google Illuminate and OpenRead compare in monthly traffic?
