Causality Linking

Draw cause-and-effect arrows between scenes. See which events depend on what — and what's floating without support.

⚠️

Paradox Detection

Writing time travel? Plot Forge flags when an effect appears before its cause. Your readers won't catch it — but we will.

🔄

Backside Flip

Hit Tab to flip your entire grid to a metadata view: goals, conflicts, outcomes, turning points — scene by scene.

📊

4-Mode Analysis

📐

Multi-Plot Thinking

Subplots, timelines, POVs — each gets its own column. See how they weave together or where they drift apart.

Chronological View

Toggle to see your story in timeline order. Debug cause-before-effect across time frames — instant timeline debugger.

👥

Characters & Settings

INT. DETECTIVE'S OFFICE — NIGHT

Rain hammers the window. SARAH spreads crime scene photos across the desk, arranging them like puzzle pieces.

SARAH
(tracing a connection)
The fingerprint at the warehouse matches the one from the café. He was there both times.

MARCUS
That's impossible. The café incident was three days before the warehouse even existed.

Sarah pins a red thread between two photos. The timeline doesn't add up — unless someone is lying about when it started.
