Figran
AI scientific figure generator for research illustrations, flowcharts and plots
About Figran
Figran is an AI scientific figure generator built for researchers, students and educators who need to turn complex ideas into clear visuals. Instead of wrestling with general-purpose drawing tools or expensive illustration software, you describe the figure you want in plain language and Figran produces a scientific illustration you can refine with follow-up instructions. It is designed around the real work of science communication: explaining a signaling pathway, laying out an experimental workflow, or turning a CSV into a publication-ready plot. The problem it solves is the gap between having a result and being able to show it, which is where many papers, posters and lectures stall.
What sets Figran apart is that it is purpose-built for scientific figures rather than generic AI art. It supports reference images and text-guided edits, keeps labels and sequences intact, and gives researchers editable canvas elements for flowcharts and plots rather than a flat raster image. It offers access to multiple image models (including GPT Image 2, Nano Banana Pro and Seedream variants on higher tiers), exports without watermarks, and understands the formats scientists actually submit, including SVG, editable PPTX and high-resolution PNG. The tool does not validate experiments or replace scientific review; it helps you communicate what you already know.
You begin in the creation studio by describing the figure you need, naming the key objects, their relationships and the labels your reader must see. Figran generates a first version using the model and resolution you select, with the credit cost shown before you commit. From there you review the scientific details and describe any change in plain text, which creates a new version so your original is never lost. For process diagrams you can build editable flowcharts on the built-in canvas, and for quantitative results you can turn a CSV into an editable chart. When the figure is right, you download it as a PNG, or export canvas flowcharts and plots as SVG, with image layers and editable PPTX available on paid plans.
- •Text to scientific figure - Describe a mechanism, pathway or comparison and get a labeled scientific illustration you can iterate on with follow-up prompts.
- •Sketch and reference input - Upload a rough experiment sketch or reference image and Figran turns it into a consistent, clearly labeled figure while preserving the sequence.
- •Editable flowcharts and data plots - Build process diagrams and turn a CSV into a chart on a built-in canvas where shapes, labels and connections stay editable.
- •Multiple image models - Access GPT Image 2 plus GPT Image 2.5, Nano Banana Pro and Seedream models on higher tiers, with per-model credit costs shown before you generate.
- •Research-ready exports - Export watermark-free PNG at up to 4K, SVG for flowcharts and plots, and editable PPTX so figures drop straight into papers and presentations.
- •Transparent credits - Failed or timed-out generations release their reserved credits, and costs are shown up front so you always know what a figure will spend.
Figran is built for biomedical and laboratory researchers who need to explain mechanisms and workflows, graduate students preparing figures for a thesis or first paper, and educators turning dense material into something a class can follow. Researchers who want a clean graphical abstract, a labeled signaling pathway or a tidy data plot without opening a full design suite will find it fastest. Teams that iterate on figures across drafts appreciate the version history and text-guided edits, and anyone preparing a submission benefits from watermark-free, high-resolution and editable exports that respect journal requirements.
