Quanten Arc vs ScreenplayIQ
ScreenplayIQ and Quanten Arc both process screenplays automatically and return analysis quickly. The similarity ends there. ScreenplayIQ returns AI-generated feedback covering the main craft dimensions of a script. Arc maps the structural arc of the screenplay and benchmarks it against a library of produced films. Both are useful. They are answering different questions, and the one you need depends on where you are in the writing process.
What ScreenplayIQ is
ScreenplayIQ is an AI-powered script analysis platform that returns structured feedback on a screenplay's craft elements. Upload a draft and the platform returns notes covering areas including story, character, structure, dialogue, and concept. The output is qualitative and explanatory, delivered in readable prose rather than raw data. For writers who want a fast, automated read of a draft without waiting for a human coverage reader, it offers a practical alternative.
The feedback is organised, consistent in format, and produced quickly. It is most useful in the development phase, when a writer wants a structured read of a draft to help identify what is and is not working before investing in further revisions.
What AI feedback can and cannot tell you
AI-generated feedback on a screenplay is impressionistic by nature. A model trained on screenwriting principles can identify that a character arc feels incomplete, that dialogue in a particular scene reads as expository, or that the second act appears to lose momentum. These observations can be useful, especially in early development where the priority is finding and fixing story-level problems.
What AI feedback cannot do is tell you where your act-two tension plateau sits relative to the genre norm, benchmarked against the produced films your script is in conversation with. It cannot show you whether your midpoint falls inside or outside the expected structural window for your genre, or how your character presence patterns compare to the films a development executive will have as mental reference points when they read your script.
The gap is not a failure of the tool. AI feedback was designed to give writers qualitative craft observations. It was not designed to produce structural positional data benchmarked against a curated reference library. Those are different problems, and they require different approaches.
How Quanten Arc approaches the same script
Arc does not generate feedback notes. It generates structural data. Every scene in the screenplay is scored for narrative intensity. The scores are plotted as a tension curve across the full script. Structural turning points are identified and compared to genre conventions. The complete arc is then overlaid against the arcs of 250-plus produced films filtered by genre, showing precisely where the script's structure aligns with or diverges from what the genre produces.
The output is quantitative and positional. Arc does not tell you what to think about your script. It tells you where your structure sits relative to the benchmark, scene by scene, with enough specificity to act on before the script goes to anyone who matters.
Side by side
Primary function
Quanten Arc
Structural benchmarking against produced films: scene-by-scene intensity mapping, character presence, genre composition, narrative beat classification
ScreenplayIQ
AI-generated feedback notes covering story, character, structure, dialogue, and concept
Output type
Quanten Arc
Charts, tension curves, character presence maps, genre composition breakdown, and genre benchmark overlays
ScreenplayIQ
Structured written feedback organised by craft category
Benchmarking
Quanten Arc
Compares your arc directly against 364 produced films filtered by genre
ScreenplayIQ
Feedback reflects the model's general understanding of screenwriting craft. No film-by-film benchmark comparison.
Scene-level data
Quanten Arc
Every scene is scored. The full tension curve is plotted across the complete script.
ScreenplayIQ
Holistic reading of the script. No per-scene structural data produced.
Objectivity
Quanten Arc
Data-driven and consistent. The same script produces the same structural output every time.
ScreenplayIQ
AI-generated observations can vary between runs. Feedback is qualitative and interpretive.
Strict Confidentiality (No Human Involved)
Quanten Arc
Fully automated. Your screenplay is never read by a person and is deleted immediately after processing.
ScreenplayIQ
Review the platform's current data and privacy policy before uploading full drafts.
Best use case
Quanten Arc
Pre-submission structural audit on a complete draft
ScreenplayIQ
Development feedback during or after drafting, when craft-level observations are useful
What it cannot do
Quanten Arc
Does not generate qualitative prose feedback on dialogue, character voice, or thematic clarity
ScreenplayIQ
Cannot show where your structure sits relative to produced films in your genre
Which is right for you?
You are in active development and want craft-level feedback on a draft.
AI feedback tools like ScreenplayIQ are well-suited to this stage. When you are still working through story problems, character arcs, or dialogue, structured craft notes give you material to react to and revise against. The feedback is most useful when the script still has room to move.
You have a finished draft and you are preparing to submit or pitch.
Arc is designed for this moment. Once the draft is complete and you believe the story works, the remaining question is structural: does the architecture of this script match what the genre expects? Arc answers that with data rather than impressions, and the comparison to produced films gives you specific information to act on before the script goes out.
You want both kinds of feedback.
They are not mutually exclusive. Use AI feedback tools during development to work through craft-level observations, then run Arc at the end to validate the structure before submission. The two tools operate at different levels of the same problem, and using them in sequence gives you both qualitative development feedback and quantitative structural confidence.
