Chapters are essential — and they're a pain

Chapters drive discovery. Writing them drives you nuts.

YouTube rewards videos with chapter markers by showing them in search previews and letting viewers skip to what they want. Spotify and Apple use chapters to build in-app jump points that keep listeners engaged longer. Every podcast growth article says to add chapters. Almost nobody does, because writing them by hand means re-scrubbing the entire episode with a notepad open.

LumiClip is the podcast chapter generator built to kill that chore. The model transcribes the episode, detects where topics actually start and end, and returns a ranked list of chapter markers with accurate timestamps — copy-paste ready for every major platform.

Why creators pick LumiClip

Three reasons LumiClip writes better podcast chapters

Accurate, on-format, and in every platform's expected syntax.

Topic-aware boundary detection

Chapters start where the conversation actually shifts — not on 5-minute rounded marks. You get real cut points listeners can use to jump to the part they want.

Platform-perfect formatting

YouTube wants `0:00 Intro`. Spotify accepts a different format. Apple does its own thing. The generator outputs each format separately so you copy once per platform.

Works on any episode length

2-hour interview? 90-minute panel? 20-minute solo show? The pipeline scales to multi-hour episodes without losing resolution on short topic blocks.

How it works

Three steps from episode to pasted chapters

Drag in, review, paste. That's it.

  1. 1. Upload or link the episode

    Paste a podcast URL or upload MP3/MP4/WAV. Multi-hour and multi-track episodes are fine.

  2. 2. AI detects topic boundaries

    LumiClip transcribes the audio, runs topic segmentation, and proposes chapter markers with clean, on-topic titles and second-accurate timestamps.

  3. 3. Export per platform

    Copy the YouTube-formatted list, the Spotify list, or the Apple Podcasts list — each pre-sized and pre-formatted. Paste into the description field and publish.

What's inside

Features built for real podcast chapter workflows

Every detail here exists to save you a step between "finished editing" and "chapters published."

Topic-boundary segmentation

A model trained on long-form speech detects where topics genuinely change, not just where a pause lasted more than 2 seconds. Fewer false positives, cleaner outlines.

Auto-generated chapter titles

Each chapter gets a short, descriptive title that tells the listener what the section is about — ready for the description field with no editing required.

Platform-specific output

YouTube chapters need `0:00 Intro` format on separate lines. Spotify accepts slightly different formatting. Apple uses its own XML-style field. The generator outputs all three.

Editable preview

Adjust any timestamp, rewrite any title, merge two chapters, or split one — in-browser, before you paste. No exporting to a separate editor.

What changes for you

More chapters shipped, more search traffic, less busywork

Chapters done right in under a minute per episode.

Instant
Chapter markers

What was a 20-minute scrub-and-type task is now a 60-second review and paste.

Higher
YouTube search surfacing

Videos with chapters show up with rich snippets in YouTube search — direct boost to click-through from discovery.

Longer
Listener session time

On Spotify and Apple, chapters give listeners a way to land on the section they care about — which increases the chance they keep listening instead of bouncing.

More capabilities

Everything LumiClip ships around chapters

Chapters are one slice of a full podcast workflow — here's what else lives in the same dashboard.

YouTube-format output

`0:00 Intro` on its own line, sequential timestamps, descriptive titles — ready to paste into the video description field.

Spotify-format output

Chapter markers that match Spotify's expected podcast chapter structure, ready for hosts that support the format.

Apple Podcasts support

Output a chapters file that can be uploaded alongside the episode on hosts that support Apple's chapter markers.

Merge and split chapters

Too many 90-second chapters? Merge them. One 12-minute chapter covering three topics? Split it. All in-browser, drag-handle-style.

Auto-generated chapter titles

The model names each chapter based on content — no generic "Part 2" placeholders. Titles can be edited freely.

Works with video podcasts

For video podcasts, the output doubles as YouTube chapter markers — same timestamps, ready to paste into the YouTube description.

Bulk processing

Queue up a season or a back catalog and generate chapters for every episode in one batch.

Multi-language chapters

Chapter titles can be auto-translated into your audience languages if you're publishing localized feeds.
