Figviz - AI-powered STEM diagram generator for educators and researchers

What Is Figviz?

If you've ever spent 30 minutes in PowerPoint manually drawing a convex lens ray diagram, or wrestled with Illustrator trying to get the arrows right on a signaling pathway, you already know the pain. For science teachers and researchers, creating accurate, labeled diagrams isn't just tedious—it's a serious time sink that takes away from what actually matters: teaching, learning, and discovery.

That's exactly the problem Figviz was built to solve.

Figviz is an AI-powered diagram generator designed specifically for STEM—science, technology, engineering, and mathematics. Instead of fighting with generic drawing tools, you simply type a natural language description like "convex lens ray diagram with object between F and 2F" and get a clean, labeled, publication-ready diagram in seconds.

This isn't another generic image generator. While tools like DALL·E or Midjourney produce visually appealing images, they often get science wrong—showing incorrect bone structures, mislabeled organelles, or physics that defies the laws of motion. Figviz uses a self-developed AI model fine-tuned specifically for scientific and mathematical diagrams, so the output is accurate, labeled, and ready to submit or publish.

The numbers speak for themselves: over 25,000 educators and researchers have used Figviz to generate more than 320,000 diagrams, with an average user rating of 4.7–5.0 out of 5. From 8th-grade science classrooms to MIT doctoral defenses, Figviz is already making a real difference.

What You Can Do With Figviz

Every feature in Figviz is designed to save you time and deliver better results. Here's how each one works in practice.

You can use it to turn a sentence into a complete STEM diagram. Typing "block on incline free-body diagram with friction" is all it takes. The self-developed AI model interprets your description and generates an accurate, fully labeled diagram in seconds. No complex prompt engineering, no back-and-forth adjustments—just a clean result you can drop straight into your slide deck or worksheet.

You can use it to skip prompt writing entirely with 150+ preset generators. Not everyone wants to type out a description. If you need an animal cell cross-section, a Punnett square, a circuit diagram, or a free-body diagram, just pick from the library of single-purpose generators. Each one is pre-configured to produce a specific type of diagram, so you get consistent, high-quality results every time. They cover physics, biology, chemistry, earth science, mathematics, and more.

You can use it to choose the resolution that fits your workflow. Figviz exports in both PNG and SVG formats. Need a quick image for a slide? 1K or 2K works perfectly (1 credit each). Preparing a poster or a printed handout? 4K resolution delivers crisp, clear results (1.5 credits). Want to edit the diagram later? Download the SVG vector file and customize it however you like.

You can use it to upload a reference for style guidance. If you already have a diagram from a textbook or a paper, upload the PDF or image file. Figviz's AI analyzes the reference and adapts its output to match the style—so your new diagram fits seamlessly with your existing materials. This is especially useful for publishers and curriculum designers who need consistent visual standards.

You can use it to match diagrams to the right grade level. A plant cell for 8th graders looks very different from a MAPK signaling pathway for graduate students. Figviz lets you select both the subject and the difficulty level (middle school, high school, undergraduate, graduate/research). The AI then generates a diagram with the appropriate depth, complexity, and terminology for that audience.

You can use it to create labeled and blank versions in one go. Teachers love this feature: generate a "key version" with full labels for your lesson, and a "blank version" for student worksheets or quizzes—all in the same session. Your prompts are saved, so you can reuse them across classes and semesters without starting from scratch.

Who's Using Figviz?

The best way to know if a tool is right for you is to see how people like you are using it. Here's a closer look at the different types of users who rely on Figviz every day.

Physics teachers who used to spend 30 minutes on a single diagram. Sarah Klein, an 8th-grade science teacher in Ohio, remembers the days of sketching ray diagrams on a whiteboard and hoping her students could see them. Now she types a description and has a projector-ready diagram in seconds. "My students actually asked to zoom in instead of zoning out," she says, rating Figviz 4.9/5. Marcus Lee, a high school physics teacher in California, echoes the sentiment: "I used to spend 30 minutes drawing lenses and forces in PowerPoint. Now one sentence gives me a projector-ready diagram in seconds." — 4.8/5

Biology teachers who needed diagrams students could actually read from the back of the room. Emily Johnson, a middle school life science teacher in Texas, was frustrated with low-resolution cell images from Google searches. Figviz changed that. "The animal and plant cell diagrams are extremely clear—the labels are readable from the back of the classroom," she reports with a 5/5 rating. She also uses the "blank version" feature to create fill-in-the-blank worksheets instantly.

Graduate students racing against deadlines. Priya Sharma, a Molecular Biology PhD student at MIT, used Figviz to create all the pathway diagrams for her thesis defense. "Much faster than Illustrator," she says. Her rating: 4.7/5. David Chen, an Organic Chemistry postdoc at Stanford, uses Figviz to generate SN2 reaction mechanism diagrams for his grant applications. "It saves me hours of preparation time for every proposal." — 4.9/5

University professors teaching both undergrads and grad students. Dr. Maria Rodriguez, an Associate Professor of Physics at UC Berkeley, uses Figviz for both her undergraduate lectures and graduate seminars. "The diagrams are publication-quality," she says, rating the tool 4.8/5. What she values most is being able to generate everything from basic diagrams for freshmen to advanced Michelson interferometer schematics for her research group.

EdTech platforms and publishers automating content creation. Through the Figviz API, educational technology platforms and textbook publishers can integrate diagram generation directly into their workflows. A single API request generates up to 4 diagrams at once, with synchonous results returned immediately—no polling needed. This makes it possible to deliver "one diagram per lesson" quality at scale, without hiring a dedicated illustrator.

Figviz vs. Generic AI Image Tools

You might be wondering: why not just use DALL·E or Midjourney to generate diagrams? It's a fair question. Here's an honest comparison of what Figviz does differently—and where it has limitations.

In short: if you need a science or math diagram that's accurate, labeled, and ready to use, Figviz is the better choice. If you need a general-purpose image for marketing or creative projects, generic AI tools are more appropriate. They serve different purposes, and knowing which one to reach for saves you time and frustration.

Figviz Pricing Plans

Figviz is designed to be transparent and flexible. You only pay for what you need, and your credits never expire. Here's exactly how it works.

Get started with 3 free credits—no credit card required. Think of it as a risk-free trial that doesn't expire. Use them to generate a few diagrams and see if Figviz fits your workflow.

Credit consumption is simple: 1K and 2K resolution diagrams cost 1 credit each. 4K resolution costs 1.5 credits. Credits apply to both the web app and the API, so the same pool powers all your diagram generation.

We recommend most teachers start with the Plus plan at $30 for 72 credits. At 1–1.5 credits per diagram, that's roughly 48–72 diagrams—enough to cover a full semester of lesson materials, worksheets, and assessments.

For departments or schools purchasing on behalf of multiple teachers, the Power or Max plan offers the best per-credit value.

Enable Auto-refill and you'll get an extra 20% bonus credits at every refill. You can pause or cancel auto-refill anytime. Since credits never expire, there's no pressure to use them quickly.

One more thing worth noting: all generated images are watermarked-free and come with a commercial license. You can use them in your classroom, publications, presentations, and grant proposals without restrictions.
