Teaching diagrams get copied from old slides because making new ones takes too long. That is the gap PaperFig tries to close for lecturers and TAs. It is a research figure maker that runs on AI. Typical outputs are mechanisms, method workflows and graphical abstracts. Text, sketches, photos, reference images and PDFs all work as a starting point. Once a draft exists, OCR turns its labels back into editable text. An existing figure can be fed back in and enhanced instead of started over. The typical case is preparing diagrams for lectures and lab handouts. People use it to draft figures for manuscripts, build graphical abstracts, prepare grant diagrams, and make slides for lab meetings. You can try it on the free plan: 150 signup credits and 1 free figure a day for your first week, no card required. Visit PaperFig.
