Code practice for designers.
Reading the front-end your design becomes is the rep designers skip when AI hands off both ends.
Is code practice useful for designers?
Design and code sit closer than they used to: design tokens compile to CSS, components map to JSX, and a generated mockup increasingly ships as generated code. Designers who once at least read the front-end to know how a layout truly behaved now get both the design and the build handed over by AI, so the loop between intent and implementation never passes through their understanding. Code reps keep reading unfamiliar code and predicting what it does in regular use, so you can still trace why a generated component renders the way it does instead of treating the build as a black box.
A code rep, for designers
A Set shows a short snippet, say a flexbox layout with a wrap and a fixed-width child, and asks you to predict how it renders before the answer shows. That is the same act as reading the CSS behind a handed-off component to understand why your spacing looks right in the mockup but breaks on a narrow screen.

How the habit fits a designers day
Designers who touch code do it irregularly, which is exactly when the skill rusts. A short code-reading rep before deep work keeps you able to predict what a snippet does, so when you open a generated component to understand your own design's behavior, reading it is still something you can do rather than something you ask AI to explain.
Questions designers ask
- I am a designer who does not code. Is this for me? It can be, but it is optional. Code is one of six Skills and you choose your mix. The reps are about reading and predicting code, not writing it, which is the part nearest a designer's work when mockups compile to front-end. If code feels far from your role, the reasoning, reading, and writing Skills fit more directly.
- Does Senwitt teach me to code? No. The reps focus on reading unfamiliar code and predicting behavior, not building software, and Senwitt is not a coding course. The relevant act for designers is being able to trace why a generated front-end behaves as it does, kept in practice through short, general snippets rather than project code.
- Why would a designer practice reading code? Because AI now generates both your design and its build, so the implementation can stay a black box. Studies on AI coding assistance point to reading and understanding skills fading when the tool does the work. The reps keep code-reading in use, so you understand how your own layouts actually behave.

Not brain training. Brain exercise.
Senwitt is a daily brain exercise app, not a brain training program. We do not claim to improve general cognition, prevent cognitive decline, or treat any condition. Independent scientific consensus — the 2014 Stanford Center on Longevity / Max Planck Institute statement signed by 70 neuroscientists, the 2016 Simons et al. review in Psychological Science in the Public Interest, and the FTC's 2016 settlement with Lumos Labs — has concluded that “brain training” claims are not supported by the evidence. Senwitt is built on a different premise: skills you actively practice get sharper; skills you stop practicing fade.
