What is a scientific mechanism diagram?
MechFig is an AI scientific diagram generator for researchers, students, and science communicators. Paste a cascade, pathway, or mechanism-of-action description and get a clear figure for papers, posters, and PPT—without prompt engineering. Start with concrete topics such as Wnt/β-catenin signaling, the HPA axis, or the blood-brain barrier.
Unlike generic image tools, MechFig focuses on mechanism figures: ordered nodes, labeled intermediates, signaling arrows, and publishable structure. Start from curated examples (pathway, signaling, cellular, cosmetics) or describe your own cascade in plain language.
New accounts get free welcome credits to try the generator. Paid plans unlock higher monthly allowances when you need more figures. Export PNG for manuscripts and slides, reuse a curated pathway example as your starting structure, and review every label and biological relationship before publication.
How to generate a mechanism figure
- Describe the mechanism — list steps, receptors, enzymes, and the endpoint (e.g. melanin ↓ or gut barrier ↑).
- Optional: pick a scenario tab (Pathway / Signaling / Cellular / Cosmetics) and open an example as a style reference.
- Click Generate figure — MechFig builds a mechanism diagram you can download and reuse in papers or decks.
Built for research figures, not clip art
Unlike generic image tools, MechFig focuses on mechanism figures: ordered nodes, labeled intermediates, signaling arrows, and publishable structure. Start from curated examples (pathway, signaling, cellular, cosmetics) or describe your own cascade in plain language.
