The clearest version of a figure is often a whiteboard sketch that never gets redrawn. That is the gap PaperFig tries to close for researchers who think on whiteboards. It is an AI tool for drafting scientific figures. 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. There is also a figure enhancer for cleaning up an existing figure. PNG is the core download format, with TIFF/PDF export and a Faithful 4K PNG upgrade available on paid plans. The typical case is turning a photo of a whiteboard sketch into something presentable. Typical jobs are manuscript figure drafts, graphical abstracts for submissions, workflow diagrams for grants, and presentation figures. Signing up is free, with 150 credits to start (valid for 30 days) and 1 free figure per day for the first 7 days. Visit PaperFig.
