Signal-based clip detection
PeakCut scores moments from four signals — chat spikes, audio energy, on-screen events, and the story in the transcript — so the clips it surfaces are the ones that actually pop.
AI video automation platform
PeakCut
PeakCut is a full product delivery record for an AI video automation platform: it takes a long stream, interview, or raw footage and produces publish-ready short-form content without manual editing. The system scores peak moments from multiple signals, cuts vertical clips with karaoke captions, generates faceless story videos and AI-presenter episodes, speaks in a cloned voice across many languages, and schedules everything to YouTube Shorts, TikTok, Reels, and X. It proves Nythral can ship a complete AI product — pipeline, editor, generation, billing, and a launch-grade marketing site — as one system.

Delivery record
From service CRM into a modular SaaS platform.
The work connected marketing, CRM, marketplace extensions, microservices, and daily shop operations into one product architecture.
02
AI generation pipeline
Beyond clipping, the platform generates original content: AI presenters, faceless explainers, and synthesized voiceovers, rendered from a topic rather than filmed.
03
Editor and publishing
A timeline editor allows caption, music, and scene changes without re-rendering, and the output is packaged per platform with titles, hashtags, and scheduling.
04
Product, billing, and launch
The build includes subscription tiers, a generation credit system, onboarding and waitlist flow, transactional email on Nmail, and a public beta marketing site.
Product screens
Real product surfaces, staged like a launch system.
Key screens, workflow states, launch pages, and operating surfaces are arranged as a moving system instead of static thumbnails.

Peak-moment scoring
Multi-signal analysis turns hours of footage into a ranked shortlist of publish-worthy moments automatically.
Generation, not just clipping
AI presenters, faceless stories, and cloned-voice narration make it a content studio rather than a trimming tool.
End-to-end product
Pipeline, editor, publishing, billing, and a launch site delivered as one shipped AI system.
Outcomes
Built for real delivery pressure.

Peak detection
The core promise on the landing surface: paste a long VOD and PeakCut scans it, scoring peak moments and surfacing the clips worth publishing.

03
Shipped a timeline-based editor for caption styling, music, and scene order plus per-platform titles, descriptions, hashtags, and scheduling.
