For Screenwriters
Scene-by-scene intensity mapping and genre benchmarking. Compare your structural arc against films that got made, in your genre, and see exactly where yours diverges.
Every reader brings their own taste. Coverage tells you what one person thought on a given day. It doesn't tell you whether your second act structure holds up against a successful film in the same genre.
A thriller's intensity arc looks nothing like a drama's. Without a benchmark, you're writing toward an imagined standard rather than a measurable one.
You make changes, the script feels different. But is it structurally better? Gut feel is unreliable. You need a before and after you can point to.
Quanten Arc maps your screenplay against the structural patterns of 200+ produced films, giving you an objective view of where your narrative arc sits relative to genre standards. Not what someone thinks of your story, but how its shape compares to films that got made. The difference between an opinion and a benchmark.
Structural clarity at every stage, from first draft to final submission.
Scene-by-scene emotional intensity scored and visualised as a curve. See the shape of your story at a glance.
Your arc overlaid against films in the same genre. See where you match the pattern. See where you deliberately, or accidentally, diverge.
Automatic detection of act breaks and structural turning points. See whether your structure lands where it should.
Submit multiple drafts and track how the structural shape shifts. Confirm your revisions are moving the needle before you send the script out again.
Send your results to a writing partner, producer, or manager. A concrete structural benchmark is an easier conversation than "I think act two needs work."
Results in minutes, not weeks. No waiting for a reader to have availability.
Submit your screenplay PDF or Final Draft file.
Get your scene-by-scene intensity curve automatically generated.
See how your arc compares to films in the same genre.
Use the data to identify the structural sections that need work.
Check your structural shape before the script goes out. Know which act needs work before a reader tells you, and before the pass counts against you.
Submit a revised draft and see exactly how the structural arc has changed. Confirm your rewrite is improving the shape, not just the dialogue.
Share your arc analysis with a producer or development executive as part of the conversation. Structural data is a stronger starting point than 'I think the pacing is there now.'
It shows you the structural shape of your script as a scene-by-scene intensity curve, then overlays that curve against the median of produced films in the same genre. You can see at a glance where your arc matches genre conventions and where it diverges, and identify which specific scenes or acts are pulling the structure in the wrong direction.
Reader notes describe what someone experienced. The intensity arc shows you the structural shape that produced that experience. A note that says "act two drags" is an observation; an intensity map that shows a flat plateau from scenes 40 to 70 is a diagnosis you can act on.
A weak second act typically appears on the intensity map as a sustained flat section with no meaningful escalation. Comparing your arc against the genre median makes this visible: if comparable films show a wave pattern through act two and yours shows a plateau, that is the structural gap to address.
Yes. Upload each draft separately and both analyses are stored in your library. You can view the arcs side by side to see exactly which scenes changed structurally between revisions and whether the overall shape improved.
Your screenplay is deleted from our servers immediately after analysis. We retain only the structural arc data: intensity scores, act markers, and benchmark comparisons. No readable script content is ever stored.
Coverage reflects one reader's subjective response. Structural analysis measures the shape of your narrative arc against an objective benchmark. The two serve different purposes and work best in combination: coverage for craft notes, structural analysis for knowing whether the arc is where it needs to be.
The library currently includes drama, thriller, horror, romantic comedy, science fiction, and action. We continue adding films across genres. You can browse the catalogue to see what is available before uploading.
The Creator plan is designed for screenwriters. It includes screenplay uploads, scene-by-scene analysis, full benchmark access, and draft comparison. The Explorer plan gives access to the benchmark library for studying produced films without upload capability.
Your screenplay is deleted from our servers immediately after analysis. We retain only the structural arc data. No readable script content is ever stored.
Our benchmark library is built on published screenplays analysed under fair use. We don’t store or redistribute third-party scripts.
