Our icon is a triangle. Not a geometric exercise, not a logo chosen for visual harmony — a specific triangle with a clinical name that has been reshaping lives since the 1970s.
A model with a name
Cognitive Behavioural Therapy — CBT — was developed by the psychiatrist Aaron Beck in the 1960s and refined through the following decades into one of the most rigorously studied psychological treatments in existence. At its heart is a deceptively simple observation: our thoughts, feelings, and behaviors do not operate independently. They form a loop.
Thoughts shape how we feel. Feelings influence how we act. Behaviors — the things we do, the patterns we repeat — feed back into how we think. Around and around. Beck called this the cognitive triangle, and for fifty years therapists have used it to help patients find where an unhelpful cycle begins — and where it can, carefully, be interrupted.
Cognitive Behavioural Therapy is a structured, evidence-based talking therapy that helps people identify and change unhelpful thought patterns. It is one of the most widely practiced and studied psychological treatments for conditions including depression, anxiety, OCD, PTSD, and many others. Sessions typically run 45–60 minutes and focus on practical strategies rather than open-ended reflection.
When we set out to design the CBT Assistant Pro mark, the cognitive triangle was the only starting point that made sense. It is not a decorative element. It is the product.
Three nodes, one loop
The mark has three circular nodes connected by curved arms. If you are looking at it right now, the top node represents your Thoughts — the mental commentary that runs constantly in the background of every waking moment. The bottom-right is Behaviors — the actions you take, the patterns you repeat without noticing. The bottom-left is Feelings — the emotional states that color everything else.
None of these is more important than the others. There is no hierarchy. The triangle is — almost — isosceles: the two side arms are equal, the base slightly shorter, and the top node is the largest. The mark says: these three things are in relationship with each other, and all of them matter equally.
“The mark doesn’t represent CBT. It isthe CBT model — rendered as a symbol you carry with you.”
CBT Assistant Pro · Design Rationale
Why the arms are curved, not straight
The connections between the nodes are not straight lines. They are quadratic bézier curves — paths that arc gently outward before arriving at each node. This was a deliberate choice made early in the design process, and it was almost abandoned twice.
Straight edges are rigid. They say: this connects to that, end of story. Curved paths suggest something more organic — flow, process, a conversation that bends around the complexities of real human experience. They suggest that the relationships between thoughts, feelings, and behaviors are not mechanical. They are fluid. They can change.
That quality is fundamental to CBT itself. The therapy does not argue that thoughts cause feelings in a simple chain. It argues that each element influences the others, that the relationships are dynamic, and — crucially — that any point in the loop can be an entry point for change. The curved arms encode that possibility.
The dot that doesn’t belong
Positioned just above and to the right of the Thoughts node. Off-axis, intentionally asymmetric. cx 47, cy 13, r 3.8— in a mark centered at x=40, it sits 7 units to the right of center. It doesn’t balance the mark. That’s the point.
Look closely at the mark and you’ll notice something slightly off-axis: a small, warm terracotta dot sitting above and to the right of the Thoughts node. It doesn’t belong to the triangle. It sits just outside it — almost touching the top node, but not quite.
The dot is the AI presence. The assistant. The other party in the conversation. It is positioned near Thoughts because that is where CBT most often intervenes first — not in the behavior itself, not in the feeling itself, but upstream: in the thought pattern that generates them. A gentle, external perspective, arriving at precisely the moment a thought forms.
The terracotta color — warm, earthy, distinctly human — was chosen in contrast to the clinical ink-dark of the rest of the mark. The mark is precise; the dot is warm. The therapy is structured; the assistant is caring. In three and a half millimeters, the whole value proposition lives.
The slow wave
In its animated form — when it appears as a loading indicator between sessions — the mark pulses. A gentle brightness travels clockwise from node to node, arm to arm: Thoughts → Behaviors → Feelings → Thoughts. The cycle takes four seconds.
Four seconds was not an accident. We tested faster cycles — at 1.5 seconds, the mark felt like a progress spinner, urgent and anxious. That was precisely the wrong tone for a clinical product. Slower cycles felt dormant. Four seconds is the pace of a slow, deliberate breath. The pace of a moment’s reflection before responding.
The wave is clockwise — following the direction most CBT practitioners use when introducing the model to a patient: notice the thought first, then see where it goes. It is not a progress bar. It is not telling you something is loading. It is a quiet reminder that the system is present, attending, and in no particular hurry.
A mark that teaches
Most apps design their loading screens to be forgettable. We considered this. And we concluded that the loading moment — those few seconds between opening the app and entering a session — was too important to waste on a spinning circle.
For clinicians who use CBT Assistant Pro regularly, the animated triangle becomes something over time that we did not fully anticipate in design: a small ritual. A moment to land. A visual cue that says you are in a space that thinks in a particular way, and that way has a name.
CBT works, in part, because of consistency — because the cognitive triangle becomes a reliable framework that practitioners and patients return to, again and again, until it becomes a habit of mind. An instinct. Every time the mark appears — on a loading screen, on a button, in a notification badge — it is doing something small but not unimportant: it is reinforcing the model.
It is quietly asking the same question that CBT has always asked: what are you thinking right now — and where does that thought want to take you?
