Questions & answers
PostMux uses AI to transcribe your video, identify key insights, and transform them into platform-native content. Twitter threads get punchy hooks and numbered takeaways. LinkedIn carousels get visual slides. Newsletter segments get longer-form summaries with clear CTAs.
PostMux analyzes your speaking style and adapts its output to match your tone. You can also review and tweak every piece of content before it goes live — or let it auto-post if you're feeling bold.
Currently we support Twitter/X, LinkedIn, and email newsletters (via popular providers like ConvertKit, Mailchimp, and Beehiiv). More platforms are coming soon.
Absolutely. By default, PostMux queues content for your review. You can approve, edit, or reject each piece. If you prefer a hands-off approach, enable auto-posting in your settings.
Cancel anytime from your dashboard. No contracts, no cancellation fees. Your remaining subscription time will still be honored.
No. We only process the audio to generate transcripts and content. We don't store your video files. Transcripts are kept to allow re-generation of content.
