T-Sketch is an infinite canvas for sketching, drawing, and real-time collaboration. Think, plan, and create with your team on one shared canvas—whether you brainstorm on iPad or join from the web. DRAW FREELY • Infinite canvas — pan, zoom, and never run out of space. Your ideas can grow without limits. • Natural drawing — pens, brushes, and effects that respond to pressure and tilt. Use Apple Pencil for precise strokes. • Rich content — freehand strokes, lines and arrows, rich text, images, and searchable symbols on the same canvas. • Editable objects — move, resize, rotate, and recolor anything without redrawing. Iterate non-destructively. COLLABORATE IN REAL TIME • Work together — multiple people can draw and edit at the same time. See live cursors and changes as they happen. • Share by link — send a viewer or editor link so others can open the sketch in the app or in the browser. No account required for viewers. • Teams and projects — organize sketches in teams and projects. Control who has access. PRESENT AND EXPORT • Slides from your canvas — turn areas of your sketch into slides and present fullscreen. Sketch live during meetings or teaching. • Export — save as PNG images or export a full archive with all attachments for backup or sharing. MADE FOR CREATORS AND TEAMS • Cross-platform — use T-Sketch on iPad, on the web (Windows, Mac, Linux), or both. Same canvas, same collaboration. • Light and dark mode — the interface adapts to your canvas. Choose light, dark, or auto based on your background. • Optional Pro plan — free plan includes 1 project, 3 sketches, and 5 collaborators per sketch. Tronor Pro unlocks unlimited projects, sketches, and more collaborators. T-Sketch is built for visual thinking: brainstorming, system design, teaching, and creative exploration. Draw the way you think.
