Upload your recording, walk away. Castmatic handles transcription, show notes, and social content — automatically delivered to your inbox before you finish your coffee.
Built for podcast agencies, networks, and high-volume creators who can't afford to spend 4 hours on post-production
Your listeners don't care how long your show notes took to write. Spend that time on your next guest.
What used to take a VA two hours and a back-and-forth review cycle now runs unattended. Upload once. Done.
Show notes are built from your actual transcript — covering the real topics, guests, timestamps, and insights from your episode. No hallucinated filler.
Platform-specific social posts — right character count, right tone. Copy, paste, schedule. Zero extra thinking required.
No workflow to configure. No new tool to learn. Just submit and let it run.
Drop an MP3 or paste a URL to your hosted audio. Any standard format works — no conversion needed. Processing starts the moment you submit.
Whisper transcribes your audio with high accuracy. Claude then writes long-form show notes, a concise summary, and social posts for LinkedIn and X — all from your actual content.
Your complete content package lands in your inbox. Everything is structured and ready to paste — into your podcast host CMS, email newsletter, or social scheduler.
Replace this with a real quote from one of your first customers. Their exact words, in their voice — not a paraphrase. A specific, concrete outcome works best.First Last — Host of [Podcast Name] · [Number] episodes automated
MP3, WAV, M4A, OGG, and most standard podcast audio formats. You can also submit a direct URL to your hosted audio file — useful if your episode is already on a CDN, podcast host, or cloud drive.
Most episodes are fully processed within 3–8 minutes. Longer recordings (90+ minutes) may take slightly more time. You get an email notification the moment your content package is ready — no need to sit and wait.
Transcription is powered by OpenAI Whisper, which performs at near-human accuracy on clear podcast-quality audio. For strong accents, heavy crosstalk, or low-quality recordings, accuracy may vary — but we've found it handles the vast majority of podcast content without issue.
The entire pipeline is automated. Content is generated by Claude (Anthropic's AI model), working from your actual transcript. You remain in the loop — everything is a draft for you to review and approve before publishing.
Yes. During onboarding we configure prompts to match your show's voice, preferred show notes structure, header style, and social media tone. Custom templates are available — bring your existing format and we'll match it.
