A results paragraph goes in as written. The agent shows its plan, the model and the price first; nothing is charged until you press Generate.
Real run: the first draft took 45 s and 10 credits, then the agent reviewed its own figure against the paragraph. Replayed from a run on 28 October 2026; the figures, texts and label check are the ones it produced.
Real outputs from the 60 templates, each with the prompt that made it.

Scope
An image generator illustrates. It never supplies evidence. Knowing the line keeps your figures honest and saves you a wasted first try.
Refine
The figure from the first screen, changed three more ways in the same chat: a label, an arrow, a box. Each is one message or one click, 10 credits, and a new version beside the last; the earlier ones stay on the canvas, and the next edit can start from any of them.
Edit text reads every label in the figure and lists them; you retype the ones that should change. Only that text is redrawn.

The text edit has been submitted and returned — the label in the left panel now reads "NF-κB retained in cytoplasm" in place of "No nuclear translocation", with the rest of the figure unchanged.


Real run on 29 October 2026: 77 s and 10 credits; the message, the card, the reply and both figures are the ones from that chat.

Examples
Six of the 60 templates, each with the prompt that made it. Open one in the library to edit it, or use it as the reference for a figure of your own.

Structural Virology
Create a publication-ready scientific diagram of Icosahedral Virus Capsid Cutaway for Structural Virology. Render a centered icosahedral capsid with one wedge removed, expose the genome inside, and add a magnified capsomere assembly inset. Use clear directional arrows to show the main relationships and flow. Label capsid, capsomere, fivefold axis, threefold axis, genome, envelope absence, cutaway plane, and particle diameter. Use muted teal capsid, navy genome, cool gray shadows, and a small coral cutaway accent on a clean white background with precise, legible typography, balanced spacing, and no decorative elements or watermark.

Signal Transduction
Create a publication-ready scientific diagram of MAPK/ERK Cascade for Signal Transduction. Build a top-to-bottom signaling hierarchy from extracellular growth factor and receptor through RAS, RAF, MEK, ERK, nuclear entry, and transcription-factor activation. Use clear directional arrows to show the main relationships and flow. Label growth factor, receptor tyrosine kinase, GRB2, SOS, RAS-GTP, RAF, MEK, ERK, nucleus, transcription factor, proliferation, and differentiation. Use navy, teal, muted violet, pale gray compartments, and orange phosphorylation marks on a clean white background with precise, legible typography, balanced spacing, and no decorative elements or watermark.

Tumor Immunology
Create a publication-ready scientific diagram of Tumor Microenvironment for Tumor Immunology. Center a tumor nest around an abnormal vessel, distribute stromal and immune cell types by compartment, and connect activating or suppressive interactions with distinct arrow styles. Use clear directional arrows to show the main relationships and flow. Label cancer cell, cytotoxic T cell, regulatory T cell, macrophage, dendritic cell, cancer-associated fibroblast, endothelial cell, extracellular matrix, hypoxia, cytokine, and immune checkpoint. Use muted coral tumor, teal immune cells, violet stroma, blue vessel, and pale gray matrix on a clean white background with precise, legible typography, balanced spacing, and no decorative elements or watermark.

Bioengineering
Create a publication-ready scientific diagram of Microfluidic Organ-on-Chip for Bioengineering. Use an isometric exploded view with transparent microchannels above a substrate, then magnify the membrane-separated cell chambers and sensing region. Use clear directional arrows to show the main relationships and flow. Label medium inlet, vascular channel, tissue chamber, porous membrane, sensor zone, outlet, flow direction, and cultured cells. Use transparent cyan, muted coral cells, white polymer, and soft slate hardware on a clean white background with precise, legible typography, balanced spacing, and no decorative elements or watermark.

Single-Cell Genomics
Create a publication-ready scientific diagram of Single-Cell RNA-Seq Workflow for Single-Cell Genomics. Build a horizontal workflow from tissue and dissociated cells through droplet barcoding, reverse transcription, library sequencing, count matrix, dimensionality reduction, clusters, and marker interpretation. Use clear directional arrows to show the main relationships and flow. Label tissue, dissociation, viable cell, droplet, cell barcode, UMI, cDNA, sequencing reads, gene-cell matrix, UMAP, cluster, and marker gene. Use navy, teal, cyan droplets, muted violet clusters, and warm marker accents on a clean white background with precise, legible typography, balanced spacing, and no decorative elements or watermark.

Electronic Materials
Create a publication-ready scientific diagram of Semiconductor Heterojunction Band Alignment for Electronic Materials. Create three aligned energy-band panels for straddling, staggered, and broken-gap heterojunctions with common energy axes and carrier-transfer arrows. Use clear directional arrows to show the main relationships and flow. Label material A, material B, conduction band, valence band, band gap, electron affinity, Fermi level, electron, hole, type I, type II, and type III. Use navy and teal band edges, warm orange electrons, violet holes, and pale gray axes on a clean white background with precise, legible typography, balanced spacing, and no decorative elements or watermark.

Ask us a questionYou can get a picture there. Here the agent shows its plan and the cost in figures before anything is drawn, a free check reads every label back, you circle one region and only that region is redrawn, the export is an editable SVG or PowerPoint, and the disclosure sentence and license certificate come with the figure. Failed results are not charged.
No. Describe the figure and send it; the first preview is made without an account, one per browser. Sign up to keep it, remove the preview watermark and receive the rest of your free figures.
You can ask for changes to text labels, arrows, colors, elements, and layouts. Circle the relevant area and describe what to change and what to keep, such as correcting a gene name, reversing an arrow, or arranging panels side by side. Results vary, so review the whole figure after each edit. Full canvas editing currently requires a desktop browser.
No. Each edit creates a new image node connected to its source, rather than overwriting it. While you work on the canvas, you can compare versions or return to an earlier node and try another direction. Generated results are saved to your account.
New verified accounts get 3 free figures, plus 1 more for answering a short survey. Free figures are 1K. A figure is one 1K generation or edit; a 2K result, available after your first purchase, counts as two, and only results you receive are charged. After that, Basic is $9.90 a month for 20 figures, and a one-time pack starts at $9.90 for 15 figures that never expire. Every result comes without a watermark and includes its download. Explore plans and packs.
Every successful 1K or 2K result in your account includes a PNG download with no separate unlock charge. For editing elsewhere, two beta exports: an editable PowerPoint where every label is a real text box, and an editable vector package (SVG plus PowerPoint) where shapes and arrows become recolorable vector objects and labels stay text. Removing the text from a copy of a figure is one normal edit, counted as one figure; the copy stays on your canvas and serves both exports. Flat and line-art figures trace best; 3D renders and gradients come out flatter and rougher. Check the final pixel dimensions against your intended print size or submission requirements.
Yes. We claim no ownership of the figures made in your account and assign you any rights we hold, so you can publish, present, edit and sell them, with no credit line required; a free license certificate PDF is available for every figure. The limits are the rights in any material you supply and the model provider's terms, and copyright in AI-generated images varies by country. Read the publication and commercial rights page.
It depends on your target journal's policy and the type of figure. Check its rules on AI-generated images and disclosure before submission, and verify every label, structure, arrow, and image specification against your research. SFG helps create illustrations; it does not validate scientific results or guarantee journal acceptance. View the publication checklist.
Subscriptions are billed monthly or yearly, and the month’s figures are added every month on both. One-time packs never expire and never renew; larger packs cost less per figure. You can cancel a subscription’s renewal yourself with Cancel renewal on your Billing page. Cancelling is separate from a refund: contact us about your renewal date, remaining figures or refund eligibility. Open your Billing page.
Your prompts and uploaded reference images are processed by our image-service providers to generate and edit figures. Saved account figures are stored for later access; guest previews are temporary. Only upload material you are authorized to share with these services, especially unpublished or sensitive research. Contact support to request deletion of your account or related records.
