analyze
Turn dense material into a study surface.
doctor is an AI document scanner and analyzer. It corrects the capture, runs OCR and handwriting recognition, extracts formulas, tables, and diagrams, then turns the result into cited academic context.
Designed to assist study and source review, with clear confidence signals and space for human judgment.

capabilities
A complete capture-to-analysis workflow.
01
capture cleanly
AI edge detection finds the page, then crop, dewarp, rotation, and enhancement controls produce a readable source without hiding the original.
02
read every layer
OCR and handwriting recognition recover text while preserving tables, formulas, diagrams, chemistry notation, and page coordinates.
03
map the structure
Headings, definitions, claims, equations, references, and visual regions become a navigable outline instead of one undifferentiated page.
04
surface uncertainty
Low-confidence passages stay marked for a human check. A clean-looking result is never presented as proof.
05
analyze with evidence
Generate summaries, study questions, and document analysis with page-level citations attached to every important claim.
06
send work onward
Export the enhanced scan, extracted structure, and cited summary into unidrive or ask ginny to continue with the approved context.
from source to action
A study tool should make its trail visible.
doctor keeps the working source, extracted structure, and next action side by side. The goal is not to replace reading. It is to make the next careful read easier to choose.
