AI screenplay consultant delivering full script coverage in under a minute
A complete script coverage report is returned in roughly 60 seconds, replacing a process that normally takes an analyst days.
Each script is assessed on premise, originality, dialogue, structure, logic, tone, conflict, pacing and craft, with detailed notes and scores rather than a single verdict.
The report includes character summaries plus recent film comps and cast suggestions you can use directly when pitching or building projections.
You get logline, synopsis, summary, keywords, genres, content rating and a recommended release strategy in one document.
Cognition's autonomous software engineer that ships real pull requests
Devin plans, writes code, runs tests, and opens pull requests across complex, multi-repository codebases without waiting for line-by-line approval.
Devin provisions Windows, Mac, and Linux VMs, builds and runs the project, and tests in a real browser - even recording itself using the feature it built.
Mention @Devin in a thread to delegate a fix, or connect CI, PagerDuty, and issue trackers so it reacts to failures and alerts automatically.
Delegate a large task and Devin splits it across parallel cloud agents that keep working after you close your laptop, then reports back.
