Creative Tools for Visual Thinkers
Tronor builds cross-platform creative tools for illustrators, architects, educators, and teams who think visually. Based in Irvine, California, we're on a mission to make freeform visual collaboration accessible to everyone — on every device.
Our Mission
Visual thinking is a fundamental part of human creativity. Whether you're an illustrator exploring concepts, an engineer sketching architecture, a student taking visual notes, or a team brainstorming remotely — you deserve tools that feel as natural as pen and paper, but with the power of real-time collaboration and an infinite canvas.
That's why we built T-Sketch: a flexible, browser-based infinite canvas for freeform drawing, illustration, visual note-taking, and real-time collaboration. No downloads, no platform lock-in. It works on Windows, macOS, Linux, iPadOS, and ChromeOS — with pressure-sensitive stylus support, tilt detection, and palm rejection. Just open your browser and start creating.
Most creative tools force you to choose between professional drawing and collaboration. Most whiteboard tools don't support real drawing. T-Sketch bridges that gap — 24+ brush effects, atmospheric backgrounds, GPU-accelerated rendering, and real-time multi-user sync, all in one place. We're building for the way creative work actually happens: messy first, structured later.
What We Believe
Freeform First
Ideas start messy. We build tools for the discovery phase — freeform drawing, sketching, and illustration — not rigid drag-and-drop components.
Real-Time Collaboration
The best ideas emerge when people think together. Real-time drawing, live cursors, and instant sync are built into everything we make.
Truly Cross-Platform
Creative tools shouldn't lock you into one platform. T-Sketch runs in any modern browser — Windows, macOS, Linux, iPadOS, and ChromeOS.
GPU-Accelerated Performance
Smooth 60fps rendering, instant sync, and responsive interactions — because your creativity shouldn't wait for the software to catch up.
No Barriers to Start
No downloads, no installation, no accounts required for viewers. Share a link and start collaborating immediately. Free to get started.
Built for Everyone
From architects sketching systems to students taking visual notes to illustrators exploring concepts — our tools adapt to how you think.
