What is a pathway diagram generator?

A pathway diagram generator turns a biological sequence into a labeled figure with inputs, receptors or organs, intermediate steps, arrows, feedback, and an endpoint.

Can I create Wnt, HPA axis, and signaling pathway diagrams?

Yes. Start from the Wnt/β-catenin, HPA axis, MAPK/ERK, or NF-κB examples, then replace the nodes and endpoint with your research context.

How is this different from a generic flowchart tool?

MechFig organizes figures around biological compartments, pathway nodes, activation or inhibition, and research-ready mechanism structure.

Is the pathway diagram generator free to try?

New accounts receive free welcome credits, and all public pathway examples can be browsed before generation.

AI pathway diagram generator

Pathway diagram generator for biology and research

Turn a biological pathway description into a clear, labeled research figure. MechFig is an AI pathway diagram generator for signaling cascades, endocrine axes, cellular mechanisms, and molecular pathways.

Start from a real example such as Wnt/β-catenin or the HPA axis, edit the nodes and endpoint, then generate a pathway figure for papers, posters, or teaching slides.

What you can generate

Biological pathway diagrams with activation, inhibition, and feedback arrows
Signaling pathways from receptor binding to transcriptional or cellular endpoints
Endocrine axis diagrams with organs, hormones, and negative feedback
Reusable pathway examples for Wnt, MAPK/ERK, NF-κB, autophagy, and more

How it works

1Choose a relevant pathway example or list your own trigger, nodes, compartments, and endpoint.
2Specify a horizontal cascade, vertical axis, or OFF-versus-ON comparison.
3Generate the pathway diagram, then verify every label and arrow before export.

Open example

From pathway text to a readable scientific figure

A useful pathway diagram has a visible logic chain: input → biological components → intermediate signaling or transport → endpoint. MechFig starts from this structure instead of generic decorative biology imagery.

For Wnt signaling, the HPA axis, or inflammation pathways, open the matching example first and adapt its scientifically recognizable layout.
