The control layer your design tools don't own.

A systemwide pen stabilizer for macOS: smoothing, pressure curves, rulers, perspective, grid and composition guides, in every app that takes a pen, with no setup per app.

What is Hej Stylus?

Hej Stylus! is a systemwide pen stabilizer for macOS that smoothes your stylus input across every app that takes a pen, with no per-app setup. It smoothes position, pressure, tilt and rotation in real time through six smoothing slots, adds pressure curve mapping (linear, bezier, draw), six ruler tools, five perspective modes, a configurable grid and twenty-four composition guides. It runs as a menubar agent with a dockable interface and a click-through overlay, so nothing is written into your document. Pressure features need a pressure-sensitive pen on a graphics tablet. One-time purchase for €30, with a free 14-day trial. Always free basic smoothing. macOS only.

The Features

The Hej Stylus! V4 panel showing all sections: Presets, Recording, Smoothing, Pressure Mapping, Modulation, Rulers, Perspective and Grids.

  • Recording / Playback: capture a whole session or a single stroke, then play it back.
  • Smoothing: six slots in one row: three for position, one each for pressure, tilt and rotation, with ten filters across four channels.
  • Pressure Mapping: three curve modes: linear, bezier and freehand draw.

  • Perspective: five modes: Precise Angles and 1, 2, 3 and 4-Point, the 4-Point fully parametric.

Loved by illustrators

Artwork by Tommy Parker
As someone who can't consistently draw a smooth curve, I am forever grateful that Eilert created Hej Stylus. I can now actually focus on the work rather than my terrible curves!

Artwork by Curt Merlo
Hej Stylus is so ingrained into my process that I use it for every piece I make. I dread the day the power goes out and I am sent back into the dark ages when my lines were shaky.

FAQ

Frequently asked questions

Does Hej Stylus work with Wacom Intuos and Cintiq?

Yes. Hej Stylus! works with every graphics tablet that is recognized by macOS, including all Wacom Intuos, Cintiq, Huion, and Apple Pencil via Sidecar.

Does it support Photoshop and Illustrator at the same time?

Yes. Hej Stylus! is a global, system-wide stabilizer. It runs in the background and applies smoothing to any application that accepts pen input: Photoshop, Illustrator, Clip Studio Paint, Affinity, and more. No per-app setup needed.

What is the difference between Hej Stylus V3 and V4?

V4 is a full rewrite with a new UI, improved smoothing algorithms, and new features like physics-based smoothing, pressure buffer, and an expanded perspective toolset. V3 licenses are not transferable: V4 is a separate product.

Do I need Hej Stylus if my tablet already has pressure curves?

Tablet drivers offer basic pressure remapping, but Hej Stylus goes further: it smoothes position, pressure, tilt, and rotation simultaneously, adds ruler and perspective tools, and works identically across all apps without per-app configuration.

Is Hej Stylus available for Windows?

No. Hej Stylus! is macOS only. There are no plans for a Windows version at this time.

How much does it cost?

Hej Stylus! costs €30 as a one-time purchase. There is no subscription. The basic position stabilizer is free forever, and a 14-day trial of all features is included.

Is there an educational discount?

Yes. Educators and educational institutions can request a free license by emailing hello@hejstylus.com.
