Hi Product Hunt! 👋 We built Figviz after watching teachers spend entire evenings redrawing cell diagrams and free-body diagrams for worksheets — and watching generic AI image tools get the science embarrassingly wrong (mitochondria floating outside the cell, force arrows pointing nowhere). Figviz is a diagram generator that takes a sentence, a topic, or a PDF and returns an accurate, labeled figure for biology, chemistry, physics, and K-12 math. It's built for classrooms first: 🔬 Accurate + labeled — diagrams follow textbook conventions, every part named 📄 PDF in, diagram out — drop in a worksheet or paper, get the figure it needs 🖨️ Print-ready PNG export for worksheets, slides, and study notes 🧰 150+ free single-purpose tools (cell diagram maker, unit circle, and more) 🧑‍💻 API + MCP server — generate diagrams from your own apps or from Claude Pricing is simple: free to start (3 credits), then pay-as-you-go. No subscription. 🎁 For Product Hunt: our founding Lifetime deal is live — $199 (reg. $299) for 1,200 credits + 60/mo for a year, limited to 50 seats. We'd love your feedback — especially from teachers, students, and anyone who makes science content. What diagram should we nail next? — The Figviz Team
