Best BioRender Alternatives: AI Scientific Figure Tools (2026)

How should you choose a scientific figure tool?

Choose by who does the layout: you placing every icon yourself, or AI drawing a first version that you then correct.

Scientific figures come in two families: concept figures that turn an idea into a diagram (graphical abstracts, signaling pathways, experimental schematics, study flowcharts) and data plots. This post covers concept figures and schematics. Data plots should come from your analysis tool or code, because an image model can invent numbers.

BioRender — the standard icon library

BioRender is the figure tool most life scientists know. You drag pre-drawn icons and templates onto a canvas, then add arrows and labels.

• A huge icon library — cells, proteins, and lab equipment are already drawn, so you never draw shapes yourself.
• Precise manual control — you decide where every element goes. The trade-off is time: every figure is assembled by hand.
• Free plan limits — according to BioRender's pricing page, the free plan allows up to 3 figures for personal and educational use and does not include permission to publish. Publishing requires a paid plan (Individual from $35/month billed annually).

Best for: researchers whose lab or university already holds a license and who are comfortable assembling figures from icons.

FigureLabs — AI that draws from text and sketches

FigureLabs launched in August 2025 as an AI tool for scientific illustration and quickly became one of the best-known names in the category.

• Text and sketch to figure — describe the figure or upload a hand sketch, and it returns a publication-style illustration.
• Partial edits and vectorization — fix labels, redraw a selected region, and convert results into editable SVG or PPTX.
• Credit-based — generations, redraws, and vector exports each use credits, and free use is limited to non-commercial purposes.

Best for: researchers who handle figures as a separate task and are comfortable writing English prompts.

Nubint Figure — an AI figure tool inside your writing workflow

Nubint Figure draws scientific figures from a sentence, lets you refine them on a canvas, and exports submission-ready files. It runs on the same account and plan as Nubint's paper writing and review tools.

• Three kinds of figures — illustrations (graphical abstracts, pathways, cell and device schematics), flowcharts (study flows, model architectures, cycles, timelines), and charts (beta). Charts are drawn by code from your uploaded table (CSV or XLSX), not by an image model, so no numbers are invented.
• 82 templates — pick a flowchart, model architecture, cycle, or timeline template and Nubint keeps its layout while swapping in your content.
• Start from a sketch or reference — three quick modes ("sketch to figure", "match a reference figure", "polish a figure") redraw hand sketches or old figures for submission.
• Point at what to change — edit by chat, redraw only a selected region, or change just the text inside the figure. Background removal, white background, aspect ratio, and upscaling are one click each.
• Submission-ready export — PNG and JPG on every plan, editable SVG and PPTX on paid plans. Each export can include a publication license certificate you can attach to your submission.

Best for: graduate students and researchers who want a graphical abstract or schematic draft fast, without assembling icons, and who write their paper in the same place.

Why isn't general image AI recommended for submission figures?

General image models struggle with labels and scientific accuracy, and you can't fix one wrong word without regenerating the whole image.

They produce attractive images, but label spelling often breaks and pathway steps can come out in the wrong order. AI figure tools follow the conventions of scientific figures (white backgrounds, tidy labels, panel layouts) and let you edit at the level of a word or a region.

Can I use BioRender's free plan for a published paper?

Not according to BioRender's pricing page. The free plan is for personal and educational use and doesn't include permission to publish.

If your institution holds a BioRender license, you may be able to publish under it, so check first. If not, and you want to start free, Nubint Figure lets you create figures and export PNG on the free plan. Whatever tool you use, check your target journal's image policy before submitting.

What is the best free BioRender alternative?

BioRender, FigureLabs, and Nubint Figure all have free tiers, but what you can do on each differs.

BioRender's free plan stops at 3 figures with no publication rights, and FigureLabs' free use is non-commercial. Nubint Figure's free plan needs no credit card and exports PNG and JPG at 1K. Drawing one or two real figures from your own paper is the most reliable way to see which fits how you work.

Can I submit AI-generated figures to a journal?

It depends on the journal. Many publishers ask you to disclose AI-generated images, and some don't accept generative AI images at all.

Check the AI image policy in your target journal's author guidelines, and if it's allowed, name the tool in the figure caption or methods section. Nubint Figure's publication license certificate proves your right to use the figure in a paper. It doesn't replace the journal's own AI policy.

Can I make data plots with AI?

Not with an image generator, because it can invent numbers.

Bar, line, and scatter plots must plot real values with code. Nubint Figure's charts (beta) are drawn with code (matplotlib) from the table you upload, so no value outside your data appears. Plots that need analysis, such as statistical tests or survival curves, belong in your analysis tool.

Conclusion

BioRender is the right fit for icon-level manual control. FigureLabs and Nubint Figure fit when you want a scientific figure draft from one sentence. If you also want to write and review your paper in the same place, start Nubint Figure for free and draw your first figure.
