Fault Lines

The cracks
in your world,
found for you.

An AI close-reader for fiction writers.

The Accord — Chapter IAnalysing…

The Binding prohibited unsolicited contact. The system’s first message arrived three minutes before her request was logged. The panel had scored her withdrawal as irreversible, though no one had explained how that threshold was calibrated. Somewhere in the founding charter was a clause that, if invoked, would dissolve the Binding entirely.

Chapter I

Every world has cracks.
You wrote them in without knowing.

The timeline contradiction buried in chapter seven. The law your system invokes in act two that it quietly ignores in act four. The character who knows something she has no way of knowing.

These aren’t failures of imagination. They’re the cost of building something large enough to be real. Fault Lines reads your manuscript the way a structural engineer reads a building — looking for what holds, and what doesn’t.

Chapter II

Three kinds of finding.

Fault Lines doesn’t just flag errors — it reads for the shape of the problem.

Conflict

Two facts that can't both be true.

A character who left before dawn arrives in time for something that happened at midnight. A law that prohibits an action the system performs without comment.

"Farida's qualification gap is stated twice with different figures — 2y 11m here, 3y 1m earlier. One of them is wrong."
Gap

Something the world requires but never shows.

The system needs a second authorisation. The second authoriser never appears. The logic demands an explanation the prose quietly skips over.

"The panel's 'irreversible' scoring of withdrawal is never explained or contested — who calibrated it, and by what standard?"
What-if

A fork in the road the story didn't take.

Not an error — an opening. A rule, a decision, or an event that creates a door the draft left closed. The question that sharpens everything around it.

"What if the panel's faithful waiting is the structural violence — not a failure of the Binding, but its perfect operation?"
