How Kleus works

By Yanis, founder of Kleus · Last updated 26 August 2026

Kleus works in four beats. You say what you want to learn; it builds a chaptered plan. Each day one 15 to 60 minute assignment arrives on WhatsApp or Telegram. You submit what you produced; it scores it out of 100, tells you what was solid, flaky or lacking, and writes tomorrow from the result. Miss a day and the plan bends. Go quiet and Kleus follows up, text first, a call only if you keep ignoring it.

1. Tell it what you want

Roman history, Python, negotiation, Spanish. You give Kleus the goal and the reason behind it, how many minutes a day you are actually willing to spend, and which days. It builds the plan while you wait: chapters, in order, sized to the time you committed.

The session length you pick is the destination, not day one. The first three real assignments ramp up to it from fifteen minutes, because a plan that opens with your hardest commitment is a plan that gets abandoned in week one.

2. Do today's assignment

One assignment lands in your chat. You read it, you do the work, and you submit what you produced: a paragraph, a program, a translation, an argument. Every assignment ends in something that exists afterwards. That is the deliberate part. A lesson you only watched leaves nothing behind to check.

3. Kleus grades it and writes tomorrow

Each assignment closes with a short check on what you produced. Kleus scores it out of 100 and names a band. The form is fixed everywhere: 82/100 - flaky on the proofs. Redo Thursday.

BandScoreWhat happens next
Solidabove 80The plan moves on. Nothing is repeated for the sake of it.
Flaky50 to 80The task counts as done, and the concepts you were weak on are pushed into the rest of the chapter so they come back inside your ordinary work.
Lackingbelow 50A focused redo is scheduled automatically, spaced a real assignment away rather than dumped on you tomorrow. No lecture, no choice to make.

The bands describe the work, never the person. Lacking work does not earn a lecture; it earns a redo. That distinction is not decoration: feedback that points at the self backfires often enough that it is the single most common way well-meant grading makes people worse.

Kleus decides when the redo lands, not you. Deadlines somebody else sets, spaced evenly, produce better work and fewer late submissions than deadlines people set for themselves (Ariely and Wertenbroch, 2002). People space their own badly.

4. Miss a day, keep the plan

Nothing breaks. There is no streak to lose and nothing to restart. The missed day is logged without commentary and the plan reshuffles around your life, so the chapter still gets finished. Missing one day barely dents a habit in the research; what breaks people is the shame spiral afterwards, and a plan that resets to zero is a machine for producing one.

What happens when you go quiet

This is the escalation lever, not the routine. It is described here in full, once, because a product that contacts you should be exact about when.

  1. Your assignment arrives at your scheduled time and goes unanswered.
  2. A nudge follows in the same chat, about an hour later.
  3. If the silence keeps going, the follow-ups get firmer, at the pressure level you set.
  4. If you keep ignoring them, Kleus places a real phone call at your scheduled time. It is the last rung, not the product.

You set how far that goes, from a gentle nudge to drill sergeant, and you can change it whenever you like. The default is high standards plus the assumption you can meet them, because controlling language mostly produces resistance.

Where it all happens

  • WhatsApp or Telegram. The assignment, the grade, the nudges. Whichever one you already live in.
  • The web dashboard. Your plan, your history, and a mirror inbox that shows every message from every channel in one place.
  • Email. Mirrors the daily assignment and the weekly verdict, so nothing depends on you keeping one app open.

The part nothing else does

A streak counts the days you opened an app. A body-doubling session proves you sat there. A checkbox proves you tapped it. None of them can tell whether you learned anything, and neither can you, until it is too late. Kleus grades work you produced, and writes tomorrow from the result. That is the whole argument, and the category page puts it next to what everything else in this space actually checks.

Try one real assignment. No account.

Not a demo. A real Kleus assignment, graded for real. Do it, see the grade, then decide.
