The sauna
Heat, firewood and a philosophy of life. The natural meeting place in Bastu-Kalle’s universe.
Welcome to Boden
A growing northern Swedish comic world about sauna, coffee, friendship and the strangely important questions that arise in between.
“AI is the tool. Bastu-Kalle is the story.”
Bastu-Kalle
PontusBastu-Kalle Boden
Recurring characters, fixed settings, sauna philosophy, coffee and everyday life in northern Sweden. The goal is a comic world that feels familiar every time you open the door.
Heat, firewood and a philosophy of life. The natural meeting place in Bastu-Kalle’s universe.
Not a prop – part of the world-building. Some questions simply become easier after a cup.
Recurring characters and settings are developed with a consistent visual style, so the world remains recognisable from one story to the next.
Characters
Meet some of the recurring characters in Bastu-Kalle’s world – each with their own role, personality and place in the stories.

The centre of the world. Sauna, towel, coffee and an unwavering belief that most things can be solved at the right temperature.

A recurring part of Bastu-Kalle’s world, often right in the middle of events when Kalle’s ideas have to work in practice.

The sauna’s sacred coffee machine. High-tech, proud and a little sensitive.
The sauna’s charming heat source, with a personality all her own – warm, expressive and always at the centre of events.

One of Bastu-Kalle’s recurring originals. Igge has an unmistakable style of his own and likes to keep Refreshers close at hand.
How a page is built
The AI-assisted images do not come from a single button press. Story, visual references, selection and correction work together to keep the world coherent.
First the scene, the joke and the required characters are decided.
The correct character and setting references are selected before any new image is created.
Images are created, reviewed and rejected until the characters, setting and expression are right.
Dialogue is added and the finished panel is saved as the foundation for the next page.
AI & creation
One of the core ideas behind Bastu-Kalle is to explore how far a coherent comic world can be built with artificial intelligence as one of the creative tools.
The characters, stories, humour and settings are developed and directed by me. AI helps give the ideas visual form.
Because of a disability, I cannot create images with my hands in the way many traditional artists can. AI has opened a door that was previously closed and made it possible to give long-held ideas a visual form.
About the images
I am aware of the debate around artificial intelligence, copyright and the ethical questions that come with the technology. At the same time, AI has made it possible for me to work visually with ideas, stories, characters and imagined worlds that I have carried with me for a long time.
I describe, choose, change, reject and continue building. Characters and settings develop into established visual models and are reused to create continuity. The images are therefore not simply the result of an algorithm, but also of storytelling, humour, experience, selection and long-term world-building.

Press & presentation
“AI is the tool. Bastu-Kalle is the story.”
Bastu-Kalle is an AI-assisted comic world from Boden, with sauna, coffee, friendship and northern humour as recurring themes. The same characters and settings return to create continuity over time.
AI makes it possible to give a long-held inner visual world a visible form despite practical limitations in traditional image-making. The technology is used as a tool in a directed, iterative storytelling process.
About Bastu-Kalle
Bastu-Kalle is a long-term comic project. The ambition is to create a clear and recognisable world with recurring personalities, established settings, albums, books and stories that can live on over time.
This website is the project’s digital home and can continue to grow with more characters, stories, press material, ordering links and a larger comics archive.
