“Four-panel CRISPR-Cas9 mechanism: (a) guide RNA scanning DNA, (b) PAM recognition, (c) double-strand break, (d) NHEJ vs HDR repair.”
Figure 1. Mechanism of CRISPR-Cas9 genome editing. (a) The Cas9–guide RNA complex scans double-stranded DNA for a protospacer-adjacent motif (PAM). (b) PAM recognition triggers R-loop formation as the guide RNA base-pairs with the target strand. (c) Cas9 introduces a blunt double-strand break three base pairs upstream of the PAM. (d) The break is resolved by error-prone non-homologous end joining (NHEJ) or template-directed homology-directed repair (HDR).
A figure caption for every kind of figure
Multi-panel layouts, statistical charts, workflows or mechanisms — the figure caption matches the figure and your target journal's conventions.

Try it nowFrom description to figure caption in three steps
Describe the figure
Write what each panel shows — "(a) UMAP of 12k cells, (b) marker genes…" — and add the abbreviations you used.
Generate the figure caption
Our AI writes a precise, journal-style figure caption with panel labels, defined abbreviations and the correct tone for your target journal.
Copy and refine
Copy it straight into your manuscript, tweak any detail, or head to the workbench to make the figure it describes.
Frequently asked questions
- Is the figure caption generator free?
- Yes — writing a figure caption is free, you just need a (free) LabFig account. Generating the actual figure in the workbench is what uses credits.
- Will it label my panels correctly?
- Yes. Describe each panel and the caption is structured with panel labels (a, b, c) in the order you give them, so readers can follow along.
- Does it define abbreviations?
- It does. List the abbreviations you used in your description and they're spelled out and defined in the caption, the way journals require.
- Can I match a specific journal style?
- Pick Nature, Cell, Science, IEEE or a clean generic style and the caption adopts that journal's tone and conventions. You can always edit the result.
- Can I reuse the figure caption in my paper?
- Absolutely. Copy the figure caption into your manuscript, edit anything you like, and reuse it however you need — it's yours.
