Thinking Gym is a voice AI coach that trains the skill that interviews actually test — structured verbal reasoning in real time. Eight minutes a session. A calibrated score every drill.
You recognise a good design when you see one. You cannot produce one under pressure in 45 minutes with someone watching.
Feedback is inconsistent. Your peer is also guessing what the interviewer wants. You leave unsure whether you passed or failed.
Useful for exploration. Gives no structure, no time pressure, no calibrated score. It agrees with whatever you say.
// All three build recognition. Interviews test production.
"The engineers who train by speaking their designs aloud — under time pressure, with a coach that responds to exactly what they said — improve faster than those who study passively."
We know voice isn't frictionless. Open-plan offices, commutes, shared apartments — speaking aloud for eight minutes isn't always practical. That's why text mode is a first-class interface. But we believe voice produces better outcomes because it replicates the actual constraint of an interview: no editing, no backspace, no pause.
We're testing that assumption with our first cohort of engineers. Here is what a session looks like.
These are live transcripts from a voice session. The coach speaks, you respond aloud — what you see here is the conversation as it was transcribed in real time.
After each drill, your TGS updates — up or down — based on which concepts you covered, how many hints you needed, and the difficulty of the drill. It's an ELO-style rating that gives you a single number to improve.
