Your software knows things nobody wrote down.

The rules that make your software unique live in code nobody reads and in the heads of people who moved on. The risk: recreating all this knowledge during a rewrite. That is where the heartbreak comes from.

Kingsheart joins your team like your best software engineer and product manager and user experience designer and that go-to expert that seems to know all the answers.

Reads and understands
Your code, your documents and your tickets, all of it, before it changes a line.
Asks
Your people the questions the code cannot answer.
Learns
A picture of how your product really works, and keeps it current as the work goes on.
Rebuilds, but better
It adds the new things you have never been able to add.

Six steps. Your team signs off every one.

Nothing moves to the next step until someone on your team says yes.

Discover
It maps the product: the code, the business rules and the people who know them.
You confirm what it found.
Plan
Findings become a plan in phases, each with the tests it must pass.
You approve the plan.
Execute
The approved plan runs, step by step.
You review the work.
Verify
The old and the new run side by side, checked rule by rule.
You accept the result.
Deploy
The rebuilt product goes live when you say so, not before.
You choose the moment.
Outcomes
A modern AI-native product with your retained IP that passed rigorous testing.
You see it all.

AI proposes. People approve. Proven systems execute.

It asks before it acts.

Kingsheart, Heart for short, finds what matters and asks the people who know.

Heart

It never forgets. And every fact has a signature.

Most AI memory is a silent scratchpad. Kingsheart keeps a versioned record of what it learned, where each fact came from and who approved it. The knowledge stays when people move on, and every next project starts further ahead.

Your code. Your IP. Your call.

Kept apartEach product Kingsheart works on lives in its own workspace, fully separate from every other one.
Nothing runs without a yesKingsheart proposes. A person on your team approves before any change is made.
Every fact has a nameWhat Kingsheart learns is kept with its source and with the person who approved it, so you can always trace why.

What Kingsheart is not

~~An editor for developers~~
~~A robot that ships on its own~~
~~A replacement for your team~~
~~Another chatbot~~

It's the team that knows your whole product, and never forgets it.

Heart asks about the order

Step 10 waits on 04, and the blocked task on 04 has been open since yesterday. Do I keep 10 waiting, or split 04 so the part 10 needs can finish on its own?
