Describe the steps, the parts and what each arrow means. The agent plans the diagram, shows the plan and the credit cost, draws it, and lets you fix one region at a time.

What a mechanism diagram is

A mechanism diagram is an explanatory schematic that shows how a process happens, step by step: which parts take part, in what order, and what each arrow means. It covers a drug’s mechanism of action, a molecular or cellular mechanism, a catalytic or materials process, and how a device works. It is an illustration of a model, not a record of a measurement.

Describe your mechanism diagram

Send this example or describe your own mechanism. The result opens on a canvas where you mark any arrow or label and say what to change.

Publication-style line-art schematic of an HPLC flow path from solvent reservoir to detector and waste
Made with this generator from a text description.

What it draws

  • Mechanism of action of a drug, antibody or inhibitor, before and after treatment.
  • Molecular and cellular mechanisms: binding, cleavage, transport, assembly, signalling steps.
  • Catalytic, electrochemical and materials processes as numbered stages.
  • How a device or apparatus works, as a cutaway or a flow of states.

What it does not draw: data

  • No charts, plots, axes, error bars or significance marks: a drawn chart implies values you did not measure.
  • No micrographs, blots, gels, scans or any image that would pass for an observation.
  • No curved electron-pushing arrows for organic reaction mechanisms: image models do not draw valid arrow pushing. Use ChemDraw or a similar editor for those and this page for the overview schematic around them.

How to describe a mechanism diagram

The agent turns these five parts into a plan and shows it, with the credit cost, before anything is generated. The more exact the names and the arrow meanings, the closer the first draft.

  1. 01

    The process and its boundary

    Name the mechanism and where it starts and ends: “how cisplatin resistance arises through ERCC1-dependent repair, from DNA cross-link to restored duplex”.

  2. 02

    Every part, by its proper name

    List the molecules, cells, materials or components that must appear, with the exact labels: gene symbols, protein names, compound names.

  3. 03

    The steps in order

    Number the steps and say what happens at each. Left to right or top to bottom; say which.

  4. 04

    What each arrow means

    Binding, conversion, transport, activation, inhibition, and whether a step is established or hypothesised. Ask for solid arrows for the former and dashed for the latter.

  5. 05

    What to leave out

    Say “no background, no gradients, no extra molecules” so the draft stays reviewable.

What reviewers expect in a mechanism diagram

Arrows carry meaning, so define them

Reviewers read a plain arrow as conversion or movement and a bar-headed line as inhibition. If the figure mixes binding, catalysis and transport, use different arrow styles and define them in the legend.

Established versus proposed

Draw steps the field agrees on with solid arrows and your hypothesis with dashed ones, and say so in the legend. A mechanism figure that presents a hypothesis as settled is a common reviewer objection.

One mechanism per figure

If two outcomes are compared (sensitive versus resistant, with and without drug), draw them as two aligned panels with the same layout, so the difference is the only thing that changes.

Labels match the text

Use the same gene symbols, protein names and abbreviations as the manuscript, and define them again in the legend; figures are read on their own.

Before submitting, check the publication checklist, write the legend with the figure legend guide, and disclose the tool as the citing guide describes for your publisher.
