About SciFig
SciFig is an AI scientific figure generator that turns any input — text prompts, hand-drawn sketches, reference images, research PDFs, or lab photos — into publication-ready scientific figures in seconds. Built specifically for researchers, PhD students, educators, and R&D teams across 11+ disciplines including biology, chemistry, physics, engineering, computer science, energy, ecology, bioengineering, and astronomy.
Unlike BioRender's fixed template library or raw AI image generators that produce flat, unusable pixels, SciFig generates science-grade figures where every shape, label, arrow, and color stays fully editable in the built-in vector canvas. Click any label to retype it. Circle any region to regenerate it. Inpaint or upscale to 8K — no full re-render needed. Export to editable PPTX, layered SVG, or 8K PNG / JPG with no Adobe Illustrator or Inkscape roundtrip.
Powered by GPT Image 2, Nano Banana Pro, and Nano Banana 2 — three image models purpose-tuned for scientific figure generation across mechanism diagrams, pathway diagrams, graphical abstracts, and annotated figures. Get 200 free credits on signup, no credit card required.
How to Use
- Choose your input — Type a text prompt, drop a hand-drawn sketch, upload a reference figure, attach a research PDF, or snap a lab photo.
- Get a publication-ready draft — SciFig generates a journal-grade scientific figure in one of 6 publication styles, or let Auto pick the best style for your topic.
- Refine without starting over — Click any label to retype it. Circle any region to regenerate. Inpaint or upscale to 8K, all without re-rendering the whole figure.
- Export and keep editing — Download as editable PPTX, layered SVG, or 8K PNG / JPG. Continue editing in the built-in vector canvas anytime — no Illustrator roundtrip needed.
Key Features

- R&D documentation — Industry teams visualizing experimental design and results.
- BioRender / Illustrator / Inkscape replacement — End-to-end editable workflow with no third-party roundtrip.
Key Features
Pros & Cons
- Offers free starter credits (200 upon signup, up to 400 with invite) with no credit card required
- All figure elements remain editable after AI generation — labels, arrows, colors can be adjusted in the built-in canvas
- Supports multiple input types (text, sketches, references, PDFs, photos) for flexible workflow
- Exports to widely-used editable formats (PPTX, layered SVG) eliminating the need for separate vector design software
- Designed specifically for scientific figure creation with journal-style presets and specialized AI models
- Free tier has a limited number of credits; additional usage likely requires purchasing credits or a subscription
- Output quality and relevance depend heavily on the quality of the input prompt and chosen model
- Requires internet access as it is a web-based SaaS tool; no offline mode available
- May not support all niche sub-disciplines or highly specific graphical conventions equally well
- Generated figures may still need manual verification and fine-tuning for absolute accuracy in complex diagrams
