Mechanism Diagram Generator
Describe the molecules, cells and relationships. LitFigure drafts one mechanism figure, then you check every arrow before it goes into a paper.

One mechanism, one reading order
Ask for a left-to-right or top-to-bottom flow so the cause and the effect are not scattered across the panel.
Arrows are claims
Activation, inhibition and binding have to match the evidence you wrote. The draft does not decide which relationship is real.
Check whether labels can be edited
Labels in whole-image SVG may be outlines rather than editable text. PPTX availability and object editability depend on the document type. Inspect the exported file before relying on text or object editing.
What is a mechanism diagram generator?
A mechanism diagram shows how parts of a biological process act on each other: a receptor binds a ligand, a drug blocks a step, a cell changes state. It is a claim about relationships, not a decoration around the text.
Why it matters
- Readers use the figure to reconstruct the claim before they trust the paragraph
- A wrong arrow direction is a scientific error, even when the drawing looks polished
- A complete first draft is faster to correct than assembling icons one by one
- The same mechanism often has to be redrawn for a paper, a talk and a grant
Where it is used
- Results or discussion figures that explain a pathway
- Graphical abstracts built around one mechanism
- Review articles comparing competing models
- Grant specific aims and thesis defenses
How to make one
Name the parts and the relationships
List who acts on whom, and whether each arrow is activation, inhibition or binding.
Generate the draft
Open the studio with the description. The first image is a draft, not a finished submission.
Check arrows, then export
Correct the direction and the labels, then inspect the file type your document can actually export.
Frequently asked questions
Can this draw any biological mechanism?
It drafts biomedical mechanism figures from a written description. You still have to verify names, directions and whether the relationship is supported. It is not a substitute for a primary figure of raw data.
Should I start from text or from a sketch?
Use text when the story is clear and the layout is not. In the studio, switch to sketch mode if you already drew the layout and only need it redrawn. Edit-an-image mode is for changing a figure you already have.
Will the labels stay editable?
Labels in whole-image SVG may be outlines rather than editable text. PPTX availability and object editability depend on the document type. Inspect the exported file before relying on text or object editing.
Is the mechanism diagram generator free?
You can write the description and open the studio without paying. Verified accounts receive starter credits. Larger jobs use the credit packs on the pricing page.
