How it works
Drop a 60s clip
Any 30–60 second segment that captures the energy of your show — a strong cold open, a punchy guest moment, or a self-recorded "what this show is" intro.
We transcribe + glow it up
The clip gets transcribed via Deepgram, then a senior-producer-style AI builds a complete promo pack from the transcript: title, tagline, full 220–340 word description, and 5 social captions.
Share the public URL
Every glow-up gets a clean indexed URL like easycaststudio.com/glow-up/abc12345 with the promo pack laid out for sharing. Send to co-hosts, sponsors, or post directly to social.
Why this is different
Audio in, not a topic prompt
Most podcast generators take a typed topic and pretend the prose is yours. The Glow-Up takes your actual recorded voice — the AI writes for the show that already exists, not the show you described.
A public URL, not a chat dump
Each glow-up is a real shareable page — clean URL, OG image, indexable. Bookmark it, send it to a sponsor, link from your bio. Compounds with every glow-up your audience makes.
Honest about what audio gets used
Your audio is transcribed and discarded — we don’t store it. Only the AI-generated promo pack persists at the public URL. No private clips on our servers.
Frequently asked
- How long can my audio clip be?
- Up to 60 seconds works best — long enough to capture the show’s voice, short enough to keep transcription tight. Files larger than 10MB will be rejected (about a minute of compressed audio).
- Do you store my audio?
- No. The audio is sent to Deepgram for transcription and discarded immediately afterward. Only the AI-generated promo pack (title, tagline, description, social captions) is saved at the public URL. The transcript itself is stored alongside the promo pack so visitors can see the source.
- What audio formats work?
- MP3, M4A, WAV, OGG, and WebM. If you’re recording on a phone or laptop, every modern recording app exports one of these. Export to MP3 if your tool gives you a choice — the transcription works the same on all of them, but MP3 keeps the upload small.
- What if I don’t have a recording yet?
- Self-record a 30-second voice memo describing your show — what it’s about, who it’s for, what makes it different. The transcript-driven AI generates a real promo pack from a sketched-out audio summary. Better than typing the prompt.
- How is this different from the Launch Pack?
- The Launch Pack takes a typed topic and produces a launch bundle for a show that doesn’t exist yet. The Glow-Up takes audio of a show that does exist and produces a promo pack tuned to its actual voice. Different inputs, different use cases — Launch Pack for pre-launch planning, Glow-Up for marketing an existing show.
- Is this really free?
- Yes. Two free glow-ups per device per day. Output is yours to use commercially. Want unlimited, plus the recording studio that generates them while you record? Start a 14-day free trial of EasyCast Studio.
