Socrates
Socrates is an AI document analysis tool for researchers, students, and professionals who work with long PDFs, DOCX files, EPUBs, and other documents. You upload files and ask questions in chat to get summaries, explanations, and specific answers with inline citations pointing back to the source text.
The platform supports Deep Dive indexing for long documents, Table AI for side-by-side comparison across multiple files, and Flow AI for custom extraction workflows. Local LLM options like Llama 3 let you run analysis on Windows or Mac without sending documents to the cloud, with optional encrypted cloud processing through Azure OpenAI.
Desktop apps for Windows and macOS remain available through the project's download page. The main web domain currently redirects to socrates.im, which at the time of research showed a Firebase hosting error rather than the live product interface.

What file formats does Socrates support?
Socrates supports PDF, DOCX, EPUB, and plain text files for upload and analysis.
Can Socrates run without sending documents to the cloud?
Yes. The Windows and Mac desktop apps support local LLM processing so documents can stay on your device. Cloud processing through encrypted Azure OpenAI is also available as an option.
What is Deep Dive in Socrates?
Deep Dive indexes long documents into multiple searchable segments so the AI can retrieve accurate answers from large files instead of truncating context.
Can Socrates compare multiple documents at once?
Yes. Table AI lets you analyze multiple files side by side in a table where rows are documents and columns are AI-generated prompts or extractions.
Is there a free plan?
Socrates offers a free tier with access to core features, including local open-source model use on desktop apps with unlimited document processing for those models.
