Castmagic and AmpliForge both turn long-form audio and video into content. The difference is scope: Castmagic focuses on transcribing and repurposing an episode, while AmpliForge runs the full content supply chain — extract, generate, distribute, analyze and attribute — on EU-native, GDPR-compliant infrastructure.

Best for
B2B marketing teams wanting a full, EU-compliant content supply chain
Podcasters & creators repurposing episodes
Choose Castmagic if you're a podcaster or creator who mainly needs fast transcripts, summaries and social snippets from each episode. Choose AmpliForge if you're a B2B marketing team that needs the whole pipeline — brand-voice RAG, direct LinkedIn publishing, and analytics with CTA/UTM attribution — with EU data residency and a GDPR DPA.
Castmagic does not state EU data residency in its public documentation, so treat it as US-hosted. AmpliForge is EU-native — transcription, AI routing and storage all run in the EU, with a Data Processing Agreement under Article 28 GDPR.
AmpliForge adds the distribution and measurement half of the pipeline: direct LinkedIn publishing, a content queue, analytics, and CTA/UTM click attribution — plus brand-voice RAG grounded in your own content.
Castmagic ranges from $19 to $139/mo (annual), with a Business tier from $699–$999/mo. AmpliForge is in private beta with founding pricing and a 7-day free trial.
Turn one asset into weeks of distribution-ready content — in your brand voice, EU-native.
