Kumbatio · open source

How much of you is here today?

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

Most software models your time and assumes it is constant. Nothing models your energy. Set yours below and this page changes with it - every section reads at your level.

01Where it costs most · email

The queue you never agreed to.

Nowhere does the missing variable cost more than email. It is the one channel where any stranger can put work on your plate, for free, without asking what today has already taken from you.

Every other queue in life has feedback. A restaurant has a waitlist. A support desk has ticket numbers. Even the internet's own transport slows senders down when receivers are overwhelmed.

Email has none. Infinite senders, one finite person, no signal about capacity. This is one ordinary day. Watch it arrive.

nobody asked.
nobody had to.

02What people say · 2024–2026

We read the complaints. All of them.

Before building anything, we read what people actually say about email: Reddit threads, Hacker News arguments, app-store reviews, support forums, lawsuits. These three quotes stand for thousands.

EXH.01The vendor
I will never invest in setting up an email client again, because it will just disappear.

Said in a thousand ways, after every shutdown and every forced migration. Trust is now the scarcest feature in the category.

composite
EXH.02The machine
Search cannot find last week’s message. Sync silently loses things. The app eats gigabytes.

Boring failures, endlessly repeated, in mature products that should have solved them a decade ago. Polish is not the cure.

composite
EXH.03The AI
The AI arrived uninvited, switched itself on, and started speaking in my name.

People were not rejecting help. They were rejecting help they never agreed to. Consent is the feature.

composite: each quote is what the record says in a thousand places, in one sentence. nobody is quoted verbatim.

03Where the hurt is

“Email is broken” means six different things.

Sorted from the plumbing down to the person. The top is engineering. The middle is honesty. The bottom three are where people actually hurt, and where an energy model applies.

  1. L1

    Protocol

    leave it alone

    SMTP and IMAP are ancient, open, and the reason email outlived every walled garden. Not the enemy - the ground.

  2. L2

    App

    table stakes

    Speed, search, sync, offline. Must be fixed, and fixing them wins nothing lasting.

  3. L3

    Vendor

    won with honesty

    Local data, an open exit door, opt-in AI, published workings. Winnable with policy rather than code.

  4. L4

    Obligation

    where we work

    The only channel where any stranger can put work on your plate, for free, forever. The loop below answers this.

  5. L5

    Content

    where we work

    A note from your mother and a shipping notification, rendered as the same object, demanding equal attention.

  6. L6

    Workflow

    where we work

    Pressed into service as task manager, approval system, scheduler - jobs it has no structure for.

the coral rows share one cause: every triage system sorts by properties of the message. none sorts by the state of the person receiving it.

04What an energy-aware inbox does

Answer the sender. Capture the obligation. One act.

Say your energy is at 50 today. Mail that demands something, from outside your trusted circle, gets two things at once: the sender receives an honest acknowledgment, and the obligation is scheduled for a day you will have room for it.

Email guilt has a precise anatomy: unacknowledged, unbounded obligation. This bounds it twice. The sender is answered, so the social debt clears. The task is placed against real capacity, so the cognitive debt becomes planned work.

  1. I · arrivesfrom: stranger · wants: a decision

    It arrives

    Mail from outside your circle. It wants something, and it does not know what today cost you.

  2. II · acknowledged

    The sender gets facts

    “Received and queued · response horizon: Thursday.” Facts, never promises - an unkept promise in writing is worse than silence.

  3. III · scheduled

    Placed against capacity

    The obligation becomes planned work on a day with room for it. Planned work is tiring. It is not corrosive.

The end

This page will not ask you for anything else.

If you want the tools when they ship, the waitlist is one form. No account, no drip campaign, nothing that arrives uninvited. That would rather miss the point.
