MECHANISM
Mechanism & pathway diagrams
Describe molecules, cells and signalling relationships as one clear mechanism figure.
AI figure drafts for biomedical research
Biomedical mechanisms and workflows,
ready to revise.
Describe a mechanism or experiment and LitFigure drafts the figure. Revise in plain language or, for supported structured documents, on the canvas. Export availability and object editability depend on the document type.

ONE STUDIO, THREE FIGURE TYPES
Mechanism diagrams, experimental workflows and graphical abstracts
Start from a written description. Cover the three figure types scientific writing asks for most.
WORKFLOW
Experimental workflows
Turn multi-step procedures — isolate, activate, transduce, expand — into readable workflows.
GRAPHICAL ABSTRACT
Graphical abstracts
Compress a paper into a one-screen abstract: method, mechanism and takeaway at a glance.
Start with a complete figure
Built around biomedical research.
Explore labels, relationships and composition. Then adapt an example to your research.
Graphical abstract · AI concept exampleStart with this example →
Lipid nanoparticle delivery of mRNA
From encapsulation and cellular uptake to endosomal escape and protein expression. An AI-generated concept example, not experimental results.
Read the example brief
Create a graphical abstract of lipid nanoparticle delivery of mRNA. Show mRNA encapsulation, cellular uptake by endocytosis, endosomal escape, and ribosomal translation in the cytoplasm. Connect the stages with arrows and label mRNA, endosome, ribosome and protein. Do not depict mRNA entering the nucleus or altering DNA. No experimental data. White background, teal and coral palette.
Mechanism diagramStart with this example →
PD-1 / PD-L1 checkpoint
Connect cells, receptors and inhibitory signaling in one figure.
Read the example brief
Create a PD-1 / PD-L1 checkpoint mechanism diagram: PD-1 on a T cell binds PD-L1 on a tumor cell and inhibits T-cell activation. Label the cells and receptors, use an explicit inhibition symbol, a white background, and blue/red colors.
Experimental workflowStart with this example →
From PBMCs to CAR-T cells
Four connected stages: isolation, activation, transduction and expansion.
Read the example brief
Create an experimental workflow with exactly four numbered stages from left to right: 1. Isolate PBMCs from blood; 2. Activate T cells; 3. Transduce CAR construct; 4. Expand CAR-T cells. Show each stage with a readable label and connect adjacent stages using simple right-pointing arrows. White background, blue cells. Do not show patient infusion or treatment efficacy.
A real model revision
See how a biomedical figure changes after revision.
Compare a CAR-T workflow before and after a real natural-language edit. Download the original result to inspect it.
01 / REVISION REQUEST
“Change the thick black arrow between the first and second stages to red, keeping its shape and position.”
Switch versions and inspect the first horizontal arrow. Models can also redraw other details; compare versions before accepting a change.

No payment card required. Your first figure is on us.
02Canvas edits and exports cost nothing
Download PNG anytime. SVG converts on demand; PPTX for supported editable documents.
03Every revision keeps a version
Compare before and after, roll back when needed — no figure is ever lost to a bad edit.

AI output is a draft. Labels and scientific relationships need your review — we say so plainly.
FAQ
Frequently asked questions
Generation, editing, exports and credits — all in one place.
Can I still edit labels, colors and layout after generation?
It depends on the document type. You can keep revising in plain language, and supported structured documents expose editable canvas objects. Whole-image figures may not expose individual labels; in converted SVG, traced text may become outlines rather than text boxes.
Which export formats are supported?
PNG downloads directly for slides and layouts, SVG converts on demand, and supported editable documents export PPTX. See the help page for exact editability.
Can AI output go straight into a submission?
Treat output as a draft, not a finished figure. Verify labels, arrows and scientific relationships yourself, and check your journal’s policy on AI-assisted figures.
How do credits work?
A standard generation or a requested revision costs 1 credit; high quality costs 2. Manual canvas edits and exports are free. Subscription credits refresh per period; purchased credit packs never expire.
What happens when a generation fails?
Each image generation or requested image revision produces one candidate by default. A failed scientific inspection does not trigger an automatic redraw. If the request fails after credits are charged, the system attempts to return those credits. Contact support if the credit balance is not restored.
Is my research content safe?
Your prompts and figures live in your own project space, visible only when signed in. Downloads and sharing stay under your control.
