Most PhD students learn figure design by trial and error in tools that were never meant for science. That is the gap PaperFig tries to close for PhD students. It is a research figure maker that runs on AI. 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. Core downloads are PNG; a purchase removes the watermark, and paid plans add TIFF/PDF export and a 4K upscale for final images. It is not limited to one field; the gallery runs from biomedical and materials work to energy, environmental, bioengineering, CS/AI and geoscience. The typical case is writing up a first paper with no design background. Typical jobs are manuscript figure drafts, graphical abstracts for submissions, workflow diagrams for grants, and presentation figures. Visit PaperFig.
