# AudioPod vs NarrationBox: Which Audiobook Tool?

NarrationBox sells monthly word allowances with a large voice catalog. AudioPod narrates on your subscription credits or, with no plan, at $19 per finished hour, quoted from your manuscript — and exports ACX-spec MP3s plus an M4B with chapter markers. Neither lets you submit AI narration straight to ACX.

## AudioPod

AudioPod's Audiobook Studio takes a PDF, EPUB, DOCX or pasted text and narrates it paragraph by paragraph with multi-voice casting and voice cloning in 100+ languages. Subscribers pay from credits; without a plan it is $19 per finished hour, or $79 with a person checking the finished book.

## NarrationBox

NarrationBox is an AI narration tool. Its pricing page lists monthly plans measured in text-to-speech words (the free plan has 1,000 words with watermarked, low-quality export), voice clones per plan, word top-ups, 1,500+ voices across 80+ languages and accents, and a done-for-you audiobook service with chapter exports.

## Who each suits

- AudioPod: Self-published authors producing a finished, chaptered audiobook; subscribers who already hold credits.
- NarrationBox: Users narrating short text regularly within a monthly word allowance.

## Recommendation

Choose AudioPod to price one book upfront from its manuscript, or to narrate on credits you already have. Choose NarrationBox if a specific voice in its larger catalog is the deciding factor.

## Switching from NarrationBox

1. Export your manuscript as DOCX, EPUB or PDF.
2. Upload it to the Audiobook Studio; it splits chapters and quotes finished hours.
3. Cast voices (or clone your own), then regenerate any paragraph that needs it.
4. Export ACX-spec MP3s and an M4B with chapter markers.

## FAQ

**What is the cheapest way to narrate one book with AI?**
Without a plan, AudioPod charges $19 per finished hour, quoted from your manuscript before you pay. Subscribers narrate from monthly credits at 0.9 credits per character (about 8,333 characters per $1 of pay-as-you-go credit).

**Can I upload an AI-narrated audiobook to ACX?**
Not directly — ACX requires a human narrator. AudioPod's files meet the ACX audio spec; Audible is reached through an aggregator that distributes there or through Amazon's own virtual-voice programme.
