The tools professional screenwriters reach for.
Three engines working together: beat structure, dialogue, and rewrite assistance, each trained on how stories actually work.
Stop guessing where your structure breaks.
The beat engine reads your treatment or rough outline against proven story structure patterns. It surfaces what is present, what is missing, and what needs attention before you have invested weeks in scenes that won't hold together.
- Detects up to five structural gaps in a three-act arc
- Surfaces missing turning points with specific, not generic, notes
- Flags unresolved subplots before they become buried rewrites
- Works from rough treatments, not polished synopses
Every character speaks in their own voice.
The dialogue assistant reads your prior scenes to build a vocal fingerprint for each character. When you pause, it offers lines that sound like that character, not like generic AI output.
- Trained per-character, not per-genre
- Reads speech pattern, register, and vocabulary from your scenes
- Offers one or two alternatives, never a flood
- You decide what fits. Nothing changes without your approval.
Your script stays yours at every revision.
Rewrite mode scans as you write and flags lines worth reconsidering. It never changes a word without your permission. Every suggestion is one sentence. You read it, decide, and move on.
What it scans
Passive action lines that drain energy. On-the-nose dialogue that states what subtext should carry. Over-explained reactions that slow the scene.
What it does
Flags the line inline with a one-sentence suggestion. Shows the original beside the option. Waits for your decision before anything changes.
The philosophy
Mugafi assists. The story is yours. The most useful thing is knowing which line needed work, not having a machine write a replacement and call it theirs.
