CastCut - Conversational Podcast-to-Video Editor

A web editor where podcast hosts and B2B marketers paste their audio or video and just talk to the editor to produce branded clips, captions, and audiograms.

Target user

B2B marketers and podcast hosts turning long episodes into shareable video clips weekly

Features
  • Conversational edits like 'cut from minute 4 to 12' that respect transcript context
  • Brand kit: fonts, colors, logo, animated captions applied automatically
  • Clip suggestion engine: pre-cuts 8-12 viral moments per episode for review
  • One-click export to LinkedIn, YouTube Shorts, and X with platform-specific ratios
Why now

B2B podcasting has exploded but most teams still pay editors $200/episode; conversational tooling cuts turnaround from days to minutes.

Longevity
7/10

Short-form repurposing of long-form audio/video is a durable behavior driven by YouTube Shorts, TikTok, Reels; Opus Clip and Descript are shipping agentic features (Agent Opus, Video MCP), signaling the category is still actively expanding rather than commoditizing.Pricing - OpusClipCompare Descript, Riverside & 3 Alternatives (2026) | StackFilter

Feasibility
4/10

Non-trivial build: requires accurate multi-speaker transcription, captioning, multi-track timeline, brand templates, audiogram rendering, and tight LLM agent orchestration; well-funded competitors (Descript, Opus Clip) have shipped comparable stacks, and the GitHub trending source itself notes this needs Remotion + MCP + Agent Skills — a multi-month engineering effort for a solo team.The Best AI Tools for Editing Podcast Videos - reelmind.ai6 AI-Powered Tools to Streamline Your Podcast Video Editing
