About This Site
SciFig is a free AI scientific figure generator built for researchers. Turn text, sketches, references, PDFs, or lab photos into publication-ready scientific figures in minutes — with every label, layout, and color fully editable. SciFig is an AI scientific figure generator that turns any input — text prompts, hand-drawn sketches, reference images, research PDFs, or lab photos — into publication-ready scientific figures in seconds. Built specifically for researchers, PhD students, educators, and R&D teams across 11+ disciplines including biology, chemistry, physics, engineering, computer science, energy, ecology, bioengineering, and astronomy. Unlike BioRender's fixed template library or raw AI image generators that produce flat, unusable pixels, SciFig generates science-grade figures where every shape, label, arrow, and color stays fully editable in the built-in vector canvas. Click any label to retype it. Circle any region to regenerate it. Inpaint or upscale to 8K — no full re-render needed. Export to editable PPTX, layered SVG, or 8K PNG / JPG with no Adobe Illustrator or Inkscape roundtrip. Powered by GPT Image 2, Nano Banana Pro, and Nano Banana 2 — three image models purpose-tuned for scientific figure generation across mechanism diagrams, pathway diagrams, graphical abstracts, and annotated figures.
