Figran

Figran is an AI tool for making scientific figures from a written research description. It produces illustrations of biological systems, signaling pathways, mechanisms and experiment workflows, and includes a canvas for editable flowcharts and data plots. It is aimed at researchers, students and educators who need figures for papers, graphical abstracts, presentations and classroom material without drawing every element by hand.

The user names the key objects, their relationships and the labels a reader needs, and can attach reference images or a rough sketch of the intended layout. Figran generates an image, the user checks the scientific details, and a follow-up text instruction creates a new version while the original is kept. The credit cost is shown before each generation or edit, and failed or timed-out jobs release their credits.

Image generation runs on models such as GPT Image 2 and 2.5, Nano Banana Pro and 2, and Seedream 4.5 and 5.0, with output up to 4K on paid plans. Dedicated makers cover graphical abstracts, conceptual frameworks, PRISMA and CONSORT flow diagrams, neural network diagrams, pedigree charts, phylogenetic trees, Venn diagrams and heatmaps, and a CSV file can become an editable plot.

An account is required. Eligible new accounts get 20 welcome credits valid for 30 days, and signed-in visits can add 10 credits per 24-hour cycle. Pro costs $20 a month or $10 billed yearly for 1,200 credits, Ultimate $40 or $20 for 3,000, and Max $80 or $40 for 7,000. Images download as PNG, canvas work as SVG, and paid plans add editable PPTX.
