Your brain, unassisted

Gyms for the mind.

When machines took over physical work, we invented gyms. Now AI writes, remembers and reasons for us. ThinkReps is a 10-minute daily workout that keeps those skills yours.

Early members get 3 months of Pro free. Or start training now, no signup needed.

“Use it or lose it” applies to thinking too.

Lean on GPS and you stop learning the streets. Let autocomplete finish your sentences and you stop finding your own words. Aviation saw the same with autopilot, which is why pilots are encouraged to keep flying by hand.

AI is the most powerful autopilot ever built. Use it, but keep training the engine.

Five muscles. Three reps a day.

A rotating program like a real gym split, so every muscle gets worked three times a week.

Memory

Memorise word lists with memory-palace techniques, then recall them. The list grows as you level up.

Focus

Read a real article once, phone away, then answer questions without looking back.

Reasoning

Mental math and back-of-the-envelope estimates. No calculator, no search.

Expression

Three minutes of timed writing in your own words. Pasting is disabled.

Debate

Defend a side you didn't choose against an AI opponent, then rebut its counter-argument.

AI is your trainer, not your forklift.

1

You do the reps

Every exercise is done by you, from scratch. No copy-paste, no shortcuts.

2

The coach corrects your form

An AI coach scores your writing and arguments and tells you what to fix. It never rewrites a word for you.

3

You get measurably stronger

Levels, streaks and a strength score for each muscle show your progress over weeks.

Not another brain game.

Research on “brain training” is clear: practice mostly makes you better at the game itself. So we don't train abstract puzzles or promise a higher IQ. We train the real skills you actually use — reading carefully, remembering, estimating, writing clearly and arguing well.
