Sketch to scientific figure

Turn a rough sketch into a scientific figure draft

Sign in first, upload a reference sketch, and describe what its shapes and arrows mean. SciFig uses image-to-image generation to explore a cleaner visual version.

Visual targets for sketch refinement

These generated examples illustrate possible finish styles. They are not before-and-after records and do not prove exact sketch preservation.

Image-to-image workflow

Use the sketch as a reference, not a locked blueprint

Prepare a readable reference sketch

Use clear shapes, arrowheads, group boundaries, and short labels. Remove private or unnecessary information before upload. The current image-to-image workflow requires you to sign in before selecting a reference image.

Use high contrast and avoid crossed arrows
Number steps when sequence matters
Mark boundaries and branches clearly
Keep a local copy of the original sketch

Describe preservation priorities

State which geometry, order, connections, and visual groups must remain, and which style, color, spacing, or background may change. Do not assume the model understands the scientific meaning of a rough symbol.

Check every label and scientific term
Verify arrows, structures, and causal relationships
Compare the draft with the source data or manuscript

Compare the result with the original

Image-to-image generation may move, remove, duplicate, or reinterpret elements. Compare every node, label area, branch, arrow, and spatial relationship, then correct important geometry and text in an editing tool.

Confirm dimensions, file format, and resolution
Review the target venue's AI-use policy
Complete a final expert review before use

Image-to-image can change the meaning of a sketch

The model may alter connections, scale, labels, symbols, and topology even when asked to preserve them. Treat the output as a redraw candidate and verify it side by side with the original and supporting evidence.
