Best AI tools for scientific figures in 2026? I tested a few as a grad student.
I’ve been looking for a better way to make scientific figures for papers, posters, thesis diagrams, and graphical abstracts. BioRender is useful, but it can get expensive, and a lot of figures end up having the same recognizable style. General AI image generators can make pretty science-looking images, but most of the time they are not actually useful for research figures because the output is just a flat image.
That became the main thing I cared about: can I edit the figure after it is generated?
I tested a few options with common figure types like mechanism diagrams, cell signaling pathways, simple experimental workflows, and graphical abstracts.
The tools I tried:
- BioRender
Still good for polished biology figures and templates, but the cost adds up and the style is very recognizable.
- General AI image generators
Useful for quick visual inspiration, but not great for actual figure work. The images looked nice at first, but they were usually flat outputs that were hard to revise scientifically.
- Inkscape + BioIcons
Probably the best free/control-heavy workflow. You can make clean vector figures, but it takes more manual work and more design patience than I usually have when I’m trying to finish a poster or thesis figure.
- Figpad. ai
This was the most interesting one for me because the generated figure stayed editable. I could change labels, move arrows, adjust colors, resize objects, delete weird extra elements, and rearrange the layout without regenerating the entire image from scratch.
The biggest surprise was that image quality was not the real bottleneck. The bottleneck was revision.
A figure can look good at first, but the moment your PI or co-author says “move this arrow,” “change this label,” “make the mitochondria smaller,” or “can you make this match the rest of the figure,” a flat AI image becomes painful.
Another thing I liked about Figpad was the pricing model. It has a pay-as-you-go option, and the credits don’t expire, which is much better for occasional figure work. I don’t make scientific diagrams every day, so I’d rather pay when I actually need credits instead of keeping another monthly subscription running.
