ChatDOC

ChatDOC lets you chat with any PDF and get instant, fully-cited answers. Upload once, ask in plain English, and watch GPT-4o extract text, tables, charts, and formulas with pixel-level traceability. From 400-page pharma trials to 10-K filings, users cut review time by 300% and slash citation errors to near zero. Free tier starts immediately; Pro unlocks unlimited docs and vision analysis for $8.99/mo. Join 2.7 million researchers, consultants, and investors who already turn static PDFs into living knowledge.

Step 1: Ask Your File, Get Instant Answers

Upload any PDF—be it a 400-page pharma trial or a dense financial statement—and ask plain-English questions. ChatDOC returns precise excerpts plus concise explanations. No prompt engineering required.

Step 2: Select & Analyze Text or Tables

Highlight any passage or table; the AI delivers contextual summaries, trend analysis, or even cross-doc comparisons. Researchers routinely shave 2–3 hours per systematic review using this feature alone.

Step 3: Unlock GPT-4o Image Analysis—NEW

Graphs, flowcharts, and handwritten notes are now queryable. A single click extracts underlying data points or converts a photographed equation into LaTeX.

Step 4: Threaded Conversations for Deeper Knowledge

Start a thread to drill down. Each follow-up inherits full context, so you can iteratively refine hypotheses without restating background.

Step 5: Cross-Document Query to Turbocharge Research

Upload multiple papers and ask across all of them: “Which studies report p-values <0.01 for Drug X?” ChatDOC lists every match with direct links.

Step 6: Snip & Explain Math Formulas

Engineers and scientists love the one-click formula snipper: highlight an equation, receive a step-by-step derivation plus domain-specific commentary.
