00For minds whose capacity changes · open source

Your capacity changes. Most software acts like it doesn't.

Some days you have four hours. Some days you have forty minutes. Kumbatio builds open-source tools that adapt to what you can handle right now.

This page listens. Set your energy with the dial - bottom right - and it adapts with you.

01The assumption

Software was designed for a brain that doesn’t exist.

Steady attention.Stable energy.Predictable output.One default brain.

Hours present do not equal work possible. When software assumes steady attention, people with variable capacity have to do the adapting themselves: mute the noise, simplify the view, and decide what can wait.

That extra work consumes the same capacity that was already limited. Most software never notices it.

Needing a different interface is not a discipline problem. It is a design requirement.

02The thesis

Energy is not time.

Seventy-five focused hours can produce more than a hundred and sixty depleted ones.

A calendar tells us how much time is available. It does not tell us how much cognitive capacity is available inside it. Every Kumbatio tool starts with that difference.

The relationship
wh · work hours
time you were present
ph · productive hours
hours when focused work was possible

ph ≤ wh

Always
03The proof

This page is already doing it.

Everything you are reading runs on energy-system - the same open-source engine that ships in our apps. No settings page, no account, no demo video. The page you are on is the demo.

Try the levels and watch what changes. The same state and strategies are available to any app that builds on it.

Set it here - we’ll wait

Set page energy level

What moves when you do

  • type weightfollows your level, 900 down to 400
  • palettedims toward candlelight as you deplete
  • density & motionreduces at lower levels

Nothing is dropped. At low energy the page says less - it never says it worse.

04The ecosystem

One model. Different tools.

The products do different jobs. What they share is one energy state and the same rule: the person sets their capacity, and the software responds.

The engine runs outside this product line too, at entro314 labs, the studio behind Kumbatio: Meltemi, an email client in private beta, plus Entromail and Equidock, both pre-release. Each uses the SDK without adopting the rest of the Kumbatio product line. Ask for an invitation.

05The pledge

What we commit to.

Trust does not come from a promise on a landing page. These are product choices you can check in the source and in the software itself.

  • 01

    An open foundation.

    The energy-system SDK and specification are open source. You can inspect, test, and fork them.

  • 02

    Your data is not for sale.

    We do not sell personal data. You can ask to access, correct, or delete the data we hold.

  • 03

    AI that asks first.

    AI features are opt-in. Anything that speaks or acts for you requires your consent.

  • 04

    No hidden energy scoring.

    You report your own capacity. Software must not infer it unless you explicitly opt in.
