Frequently Asked Questions
Can Plottie open Visio files?
Not directly. Plottie is not a Visio clone — it is an AI-powered scientific figure tool. If you need to recreate Visio diagrams, you can describe them in text and Plottie will generate a new version.
Is Plottie better than Visio for scientific diagrams?
For scientific diagrams specifically, yes. Plottie is designed for researchers and supports mechanism diagrams, pathway illustrations, and data visualizations that Visio does not specialize in. Visio is better for IT network diagrams and floor plans.
Does Plottie work on Mac?
Yes. Plottie runs entirely in the browser and works on Mac, Windows, Linux, and Chromebooks. Visio is primarily a Windows application.
What is the best free Visio alternative?
Draw.io (diagrams.net) is the most popular free Visio alternative for general diagramming. For scientific diagrams with AI generation, Plottie offers a generous free tier. Excalidraw is great for quick informal sketches.
Can I use Visio alternatives online without installation?
Yes. Plottie, Draw.io, Lucidchart, Miro, and Excalidraw all run entirely in the browser. No software installation is needed.
