ChapterGen

ChapterGen turns uploaded recordings into editable YouTube chapter markers, making it a focused option for creators preparing long-form video or audio. Its upload-first workflow is useful before a video is public, but the free allowance covers only two short videos.

Overview

The service transcribes a recording, detects topic changes and creates descriptive chapter titles with timestamps. You can edit both before copying the result into a YouTube description. Chapters start at 0:00, matching YouTube’s expected format, though the generated divisions and titles still merit review before publishing.

Unlike tools that depend on a public video link, ChapterGen accepts uploads for unpublished, private and unlisted videos. That makes it practical during preparation, including when a creator wants to add chapters before making a video public.

Key features

File support and languages

ChapterGen supports audio-only recordings as well as video, so podcasts, interviews and voice recordings can use the same chapter workflow. The FAQ names MP4, MOV, AVI, WebM, MKV, MP3, WAV, M4A, AAC, OGG and FLAC, with a maximum file size of 500 MB. The homepage upload prompt shows a shorter list—MP4, MOV, WebM, MP3, WAV and M4A—so files in the additional FAQ formats may require checking in the upload flow.

The site says its Whisper-based AI auto-detects language and supports more than 90 languages. This is useful for multilingual creators who do not want to set a transcription language manually, though the language claim does not establish how well each language handles specialized terminology or accents.

Editable, copy-ready chapters

Generated titles and timestamps can be adjusted before copying. That control matters because automated topic boundaries may not align with the chapter divisions a creator wants to present. The output is formatted for a YouTube description, not described as a publishing or channel-management tool.

Uploaded files are automatically deleted after processing, according to the homepage. This is a useful privacy measure for unpublished material, but it is not a substitute for reviewing the service’s own data practices when handling sensitive recordings.

Pricing

The free plan costs nothing and allows two videos of up to 20 minutes each, with no signup. That is enough to try the workflow on short clips, but it is restrictive for full-length interviews, courses or podcast episodes.

Starter costs $5, paid once for five videos, with no subscription. It suits occasional users who need more than the free allowance but do not need a recurring plan. Creator costs $12, paid once for 15 videos, also with no subscription; it is the better fit for a small batch of longer-form projects. The published plan terms do not state a per-video duration allowance for either paid package, so creators should confirm that their intended uploads fit before buying.

Platforms

ChapterGen runs on the web. Its file-upload workflow and copyable output suit creators working from a browser, while no other platform is identified.

Who it's for

ChapterGen is best suited to YouTube creators who want chapter text from an audio or video file, especially podcast and course creators working with long recordings. It also makes sense for tutorials, webinars, product reviews and vlogs. The upload route is a particular advantage when a video is not yet public. It is less compelling for users needing substantial free capacity or a broader publishing workflow.

Pros and cons

Pros

• Works from uploads, including unpublished, private and unlisted videos, so a public YouTube URL is not a prerequisite.
• Handles audio-only files as well as video, covering podcast and interview workflows.
• Editable titles and timestamps let creators refine chapter boundaries before copying.
• One-time Starter and Creator plans avoid a subscription commitment.
• Automatic deletion after processing is a privacy-conscious approach for uploaded recordings.

Cons

• The free plan stops at two videos of up to 20 minutes each, limiting its usefulness for longer recordings.
• Paid plans sell fixed video batches, which may not suit creators who need ongoing chapter generation.
• The homepage upload prompt names fewer formats than the FAQ, creating uncertainty for some file types.
• Generated chapters still need editorial review; the service creates suggested titles and boundaries rather than replacing that judgment.

Alternatives

For broader podcast-related tools, see Podcast Show Notes Software. Pick DomeScribe instead if you want an option spanning mobile, desktop and web with a free tier that includes 30 minutes of transcription and TXT export. CraftNote is a better fit when calendar syncing and weekly recording allowances matter more than YouTube chapter formatting. Choose audien·to for multiple output types, a 90-minute daily free allowance and 67-language support. Deciphr may suit users seeking a wider written-content workflow, with a free text-only tier up to 40 minutes. DriftNote is oriented toward podcast summaries and Notion sync, rather than direct YouTube chapter generation. EditClips.online offers a broad collection of browser tools, while Podlink focuses on podcast download analytics and show pages. Podnotes is another transcription and content option, with 50 free minutes to try its app.

Verdict

Choose ChapterGen if you need editable, YouTube-formatted chapters from an uploaded recording, particularly before a video is public, and prefer paying once for a defined batch. Look elsewhere if you need a generous free allowance, recurring high-volume use or tools beyond chapter generation.
