About

Professional broadcasting relies on precision. The difference between an amateur hobby cast and a chart-topping production often lies in pacing and structure. This tool solves the 'Editor's Nightmare' - recording 90 minutes of audio for a 30-minute slot - by forcing structure before the microphone turns on.

Unlike standard text editors, this system treats your script as a sequence of modular time-blocks. It uses a dynamic algorithm to convert word count into estimated spoken duration based on industry-standard speaking rates. This allows creators to visualize the rhythm of their show, ensure ad spots hit their required length, and balance content distribution.

The integrated Teleprompter creates a seamless workflow from writing to recording, featuring hardware-ready mirroring (for beam splitter glass) and variable scroll speeds. Whether you are producing a narrative NPR-style piece, a daily tech briefing, or a true-crime deep dive, the database of templates provides the architectural foundation used by professional networks.

Formulas

Accurate time estimation is vital for broadcast compliance. The tool uses a weighted word-count algorithm.

Segment Duration (t):

{

t_manual if lockedWR × 60 if auto

Where W is word count and R is Words Per Minute (default 150).

Total Show Runtime (T):

T = n∑i=1 t_i + T_buffer

We apply a heuristic buffer T_buffer of 5% to account for natural pauses and breath work.

Reference Data

Segment Type	Standard Duration	Role in Flow	Production Note
Cold Open	15 - 45 s	The "Hook"	Extract the most shocking quote or fact from the episode.
Intro Music / Jingle	10 - 15 s	Branding	Establish audio identity. Fade out under the host's voice.
Host Intro	30 - 60 s	Context	Who are you? What is this show? Why listen today?
Pre-Roll Ad	30 - 60 s	Monetization	High conversion slot. Mention the sponsor early.
The "Meat" (Act I)	10 - 15 m	Value Delivery	The core topic. Keep pacing tight. Use sound design.
Mid-Roll Ad	60 - 90 s	Revenue	Often read by the host (Native Ad). Highest CPM value.
Guest Feature	20 - 40 m	Authority	Interview or deep dive. requires distinct questions/segments.
Listener Mail/Q&A	5 - 8 m	Engagement	Community building. Read 1-2 questions.
Outro / CTA	30 - 45 s	Action	"Subscribe, Rate, Review". Point to show notes.

Frequently Asked Questions

Simple word counts assume a robotic, constant speed. This tool allows you to set different "Physics" for different blocks. A "Music Bed" has a fixed time regardless of words, while an "Ad Read" might need to be spoken faster (160wpm) to fit a 30-second slot. You can lock specific segments to manual time to override the calculator.

Yes. The Teleprompter mode includes a "Flip X" and "Flip Y" toggle. This mirrors the text so it appears correctly when reflected onto a beam-splitter glass placed in front of your camera lens.

No. All data is stored locally in your browser's LocalStorage. This ensures zero latency and allows you to work offline. However, clearing your browser cache will remove your saved scripts, so we recommend using the "Export JSON" feature for backups.

The "Solo Educational (20m)" template is ideal for beginners. It follows a classic "Hook -> Intro -> Content -> Summary -> Outro" structure that keeps listeners engaged without requiring complex production or guest coordination.

Yes. The "Markdown" export is compatible with Notion, Obsidian, and standard text editors. The PDF export generates a clean, read-only version for printing or sharing with co-hosts.
