Three ways to start

Words, a sketch, or a reference.

Start from whatever you have. Each path ends on the same canvas, where you refine the figure by chat.

Describe it

Write the mechanism, components, labels and layout you want. The agent turns it into a plan, then a draft.

Write a brief

Sketch it

Draw boxes, arrows and words on a sketch pad. SFG reads the sketch, confirms what it understood, then draws the figure.

Open the sketch pad

Start from a reference

Upload a figure to redraw or restyle, or open one of 60 scientific templates and adapt it to your study.

Use a reference image

Workflow

One canvas, from first draft to final figure.

Describe it, circle what to change, and compare every version side by side.

Flat illustration of a single-cell RNA sequencing workflow
Publication-style overview of drug-loaded liposome structure and experimental characterization methods
Create a flat illustration of a single-cell RNA sequencing workflow. Show sample preparation, cell capture, barcoding, reverse transcription, sequencing and cell clustering. Use soft teal, blue and coral colors, clear arrows, readable labels and a clean white background.Describe · Generate · Refine · Download
2Circle and edit
Original flat illustration with a green CD4 T cell, kept unchangedEdited flat illustration with a purple CD4 T cell and the original labels preserved

Circle the original, send a color change, and generate a connected edited version. Both images are kept. “Make this T cell purple. Keep the labels.”

3Keep every version

Tumor microenvironment · Every version stays. One original. Multiple directions. Keep them all.

Your original stays. Your change becomes a new version.

Refine

Refine the details that matter.

Labels, arrows, layout. Tell AI what to change—and keep refining until it works for you.

Give every label the right meaning.

Replace shorthand with precise terminology, without rebuilding your figure.

OriginalUnchanged
Original LNP–mRNA delivery diagram with side-by-side panels, shorthand labels and straight arrows
Refined version Ready
LNP–mRNA delivery with the labels Endosomal escape and Cytosolic translation

Change “Escape” to “Endosomal escape” and “Ribosome” to “Cytosolic translation”.

Escape → Endosomal escape · Ribosome → Cytosolic translation

More precise labels. The same scientific illustration.

Scientific Figure Generator in brief

The essentials, kept current. Compare it with BioRender, FigureLabs, SciDraw and ConceptViz.

What it is
An AI tool for researchers that creates scientific illustrations, diagrams and graphical abstracts, then lets you edit them by chat.
Inputs
A written description, a hand sketch, a reference image, your paper’s abstract or PDF, or one of 60 scientific templates.
Editing
Circle a region and describe the change; edit text, split layers, remove backgrounds or objects. A free label check flags likely errors, and a project style keeps a set of figures consistent. Every edit is kept as a version.
Styles
Line art, 3D render and flat illustration.
Models
GPT Image 2.5 Flare (default), GPT Image 2.5 Sunburst and GPT Image 2.
Output
PNG at 1K or 2K with no watermark, and a 2× upscale (2K to 4K) for print. PowerPoint export with editable text labels is in beta; editable SVG is not available.
Cost
5 free figures for new verified accounts (3 at signup, 2 the next day), then 1 free figure a day without a subscription. A 1K generation or edit uses 10 credits, a 2K result 20. Plans from $9.90/month.
Good to know
AI helps with illustration, not scientific validation. Check every label against your evidence and your journal’s AI policy.
