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 is used only to build the pack and is never shown on the public page.

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.

How it works

Step 1

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.

Step 2

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.

Step 3

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.
