Three things to know about PaperFig, an AI tool for drafting scientific figures. First, typical outputs are mechanisms, method workflows and graphical abstracts. Second, PNG is the core download format, with TIFF/PDF export and a Faithful 4K PNG upgrade available on paid plans. Third, it can also take a figure you already have and enhance it. Examples span biomedical, materials, energy, environmental, bioengineering, CS/AI and geoscience research. It suits researchers making posters building a poster centrepiece figure. The workflow is three steps: upload or paste your material, add a one-line brief about what the figure should show, then review the draft and fix any labels. Common uses include manuscript figures, graphical abstracts, mechanism and workflow diagrams for papers and grants, and figures for presentations and lab meetings. Signing up is free, with 150 credits to start (valid for 30 days) and 1 free figure per day for the first 7 days.
