As answered by people managing Abfig and Opalstack.
Abfig's answer
Academic researchers, PhD students, and scientists who need to create graphical abstracts for journal submissions.
Abfig's answer
Purpose-built for graphical abstracts, not a general design tool. You start from your paper abstract and AI generates the figure, then export it sized to your target journal's dimensions at 300 DPI as TIFF or PNG.
Abfig's answer
Unlike BioRender or general tools like PowerPoint, Graphab focuses exclusively on graphical abstracts. No design skills needed — paste your abstract, let AI generate the figure, pick your journal, and export at submission size.
Abfig's answer
Graphab started from a recurring frustration in academic publishing: after months of research, authors are asked for a graphical abstract at the last minute and end up wrestling with PowerPoint or general design tools the night before a deadline. We wanted researchers to start from what they already have — their abstract — and let AI turn it into a journal-sized figure in minutes instead of hours.
Abfig's answer
Next.js (React) and TypeScript, PostgreSQL with Drizzle ORM, Better Auth, Stripe, Tailwind CSS, and AI image-generation models for figure generation.
