The code is the easy part now.

AI writes the implementation. What's left is architecture, debugging intuition, and knowing what to build — all creative problems. Gletch keeps that part of your thinking sharp.

Get early access

Writing code stopped being the bottleneck.

Implementation is commoditised

A model writes the function in seconds. Deciding whether it's the right function is the part still worth paying for.

You reach for the same architecture

Every problem starts looking like the stack you know best, and the fit gets worse the longer you don't notice.

Debugging is a creative act

Hard bugs get solved by generating hypotheses nobody else considered — fluency under constraint, which is exactly what these exercises train.

Solving the wrong problem well

The most expensive engineering mistakes are beautifully built things nobody needed. Reframing catches that early.

Train the part AI can't do for you.

  • Practise hypothesis generation for faster debugging
  • Reframing exercises before architecture decisions
  • Track deep-work hours against a specific project
  • Capture technical and product ideas as they occur
  • Break out of stack-shaped thinking with outside inputs

Questions developers ask

No. Puzzles have one right answer. These exercises train divergent thinking — generating many viable options — which is what actually transfers to design and debugging work.
