The short version

How a change travels

Someone asks for a change. Before anything moves, Loom measures it and checks it against rules you wrote. Then it writes down what happened, every time, whether the change went through or not.

Putting it back

The undo is written at the same moment as the change

Loom works out the change that reverses it at the moment the change is made, and saves it. It does not reconstruct it afterwards from how the page looks now.

Press once and the questions that were removed come back word for word, not rewritten.

End to end

Five steps, every time

  1. 1

    Someone asks for something

    They ask in their own words, about one page. Nothing has moved yet.

  2. 2

    The AI writes down what it wants to change

    The model does not write code. It sends back an exact list: add this, remove that, move the other, change a setting.

  3. 3

    The change is measured

    Loom measures how much of the page it moves, what it touches, and whether it can be taken back cleanly.

  4. 4

    Your rules decide

    You get one of three answers: do it, hold it for a person to review, or reject it. Loom tells you which of your rules decided.

  5. 5

    What happened is written down

    Loom records who asked, what moved, and the change that puts it back. Nothing is overwritten.

Your rules

You decide what may change, before anyone asks

A rule is a line you write once: this part may be rearranged, that part may not, and anything bigger than this waits for a person. They are read the same way every time, whether or not somebody is watching.

Say the price may never be edited, and then no request edits the price. Not yours, not a visitor's, not the AI's.

The record

Every change leaves a note you can read later

The record holds who asked, what they asked for, what actually moved, which of your rules allowed it, and what putting it back would restore. Loom keeps it whether the change went through or not.

Six months later you can ask why a section moved, and get an answer rather than a guess.

When the answer is no

A refused change leaves the page exactly as it was

Nothing is half-applied. If an AI model asks for something your rules do not allow, or something that does not make sense, the page you are serving does not move. The attempt is still written down.

A request to delete your contact details is refused, your page is untouched, and the refusal is in the record.

Who is asking

The same request can get a different answer

Your rules can tell the difference between you, a colleague, a visitor and the page reacting on its own. The same words from a stranger and from you do not have to mean the same thing.

See it happen

Ask this page to rearrange itself

Everything above and below this band is a piece the page can be asked to move. Pick one, watch what happens, and read what the page wrote down about it.

What did you come here for?

Each one is a real request, checked against the rules this site runs under, exactly as it would be on a page of yours.

This site protects three things from being taken away: what it says it is for, the menu and the links at the bottom. Of the five above, three go through on their own, one stops and asks you first, and one is refused outright. The two that do not just go through are the ones worth watching.

Allowed

What the page wrote down

  1. 1

    You asked for something

    “Skip ahead. Can I undo a change the AI makes?”

  2. 2

    The change was worked out

    This moves the band about putting a change back up to just under the headline, and leaves every other band where it was. Nothing is copied and nothing is rewritten. The band now under the headline is the one that was further down.

  3. 3

    The change was measured

    10 pieces moved, in 1 step. Weighed as middling. It changes the shape of the page rather than the wording inside it.

  4. 4

    Your rules decided

    It can be taken back, it moves little enough, and it was worked out rather than guessed. Decided by the set of rules this site calls “front-door”.

  5. 5

    Putting it back

    The change that reverses this was written at the same time. It is 1 step, and it is recorded like anything else.

This change was worked out from the page itself rather than asked of an AI, which is why it is so sure of itself. Your rules do not treat the two differently: they weigh the change, never who wrote it.

These five are prepared, so the whole sequence runs here without calling an AI model. To ask for something in your own words, try the demo. It is a page you can type into.

That is the short version

This page is the short version on purpose. The documentation has the long one: what a rule can say, what the record holds field by field, and how to wire it into a page you already have.
