Old thesis figures are often low resolution and full of outdated labels. That is the gap PaperFig tries to close for researchers with old, low-quality figures. It is a research figure maker that runs on AI. An existing figure can be fed back in and enhanced instead of started over. An OCR label editor extracts every label, so a typo or renamed variable is a quick text edit instead of a rebuild. Text, sketches, photos, reference images and PDFs all work as a starting point. You download PNGs (watermarked on the free plan), while TIFF/PDF export and a Faithful 4K PNG upgrade are paid options. The typical case is reusing a figure from an old thesis or slide. Common uses include manuscript figures, graphical abstracts, mechanism and workflow diagrams for papers and grants, and figures for presentations and lab meetings. Treat the output as a draft and check it against your target journal’s requirements before submitting. Visit PaperFig.
