Professional Ink Brushes
Powered by the same vector ink engine used in T-Sketch. Each brush produces smooth, anti-aliased mesh strokes rendered with Metal.
Pressure Pen
Responds to stylus pressure, direction, and acceleration for expressive strokes. End taper creates natural-looking line terminations.
Pen
A clean, fixed-width round brush for precise annotations. Smooth strokes with prediction-based fade-out for natural endpoints.
Calligraphy
An elongated tip that rotates to follow your stroke direction. Pressure controls size for elegant, flowing handwriting.
Highlighter
A chisel-tip brush with translucent colors, ideal for marking up documents or emphasizing areas on screen.

Three steps to annotate anything on your screen.

T-Annotate lives in your menu bar. Click the icon or press Ctrl+P to start annotating.
Draw
Pick a brush from the floating toolbar and draw on top of whatever is on your screen. Switch colors and sizes on the fly.
