Audibloom

Overview

Audibloom accepts PDF, EPUB, and TXT uploads, pasted text, or a public URL. It detects narrator and character dialogue and assigns distinct voices in a multi-voice workspace, making it more suited to dialogue-rich books than a basic single-voice conversion workflow. Each chapter can be edited and rendered independently, which gives authors room to revise sections without rebuilding the whole audiobook.

Document handling addresses common manuscript problems: PDF processing removes repeated headers, footers, and page numbers and restores paragraph flow across page breaks. EPUB 2 and EPUB 3 imports preserve chapter order and the table of contents. Paid plans support PDFs up to 100 MB.

Key features

Chapter and voice control

Distinct character voices and chapter-level editing offer useful control over a full-cast production. The Free plan has six starter voices; Creator expands that to 20+ standard voices and includes multi-character narration. Higher tiers add voice cloning, with three cloned voices on Studio.

Export and rights

Audibloom currently exports chapter-level MP3 audio. The Per-book Pack includes an MP3 ZIP export, while Author Pro adds MP3 ZIP and WAV chapters. Chaptered M4B packaging is planned, so readers whose distribution workflow depends on that format should look elsewhere for now. Paid plans include commercial distribution rights and let authors keep 100% of royalties without revenue share.

Pricing

Audibloom is freemium, with no free trial. The free plan costs $0 forever and allows five minutes of generated audio per month, six starter voices, PDF/EPUB/TXT uploads, and watermarked MP3 downloads. It is useful for a short preview, but the minute cap and watermark make it unsuitable for delivering a finished commercial audiobook.

• Creator: $15/ month for two hours per month, 20+ standard voices, no-watermark MP3, and multi-character narration. This is the entry paid tier for authors producing modest amounts of audio who need clean downloads.
• Per-book Pack: $29/ book for up to 12 hours per book, MP3 ZIP export, no subscription, and no monthly cap. It suits one-off projects better than recurring production, though its export remains MP3.
• Author Pro: $39/ month for 10 hours per month, MP3 ZIP and WAV chapters, voice cloning, a pronunciation dictionary, and standard email support. It fits authors who need more editing polish or WAV delivery.
• Studio: $99/ month for 30 hours per month, three cloned voices, five parallel books, a priority render queue, a dedicated Slack channel, and weekly office hours. Its capacity and support are aimed at small presses managing several books at once.

The free tier is sharply limited in both time and watermarking; Creator removes the watermark but still caps monthly production at two hours. Per-book Pack avoids a recurring bill, while the monthly plans make more sense for ongoing output. Match the quota to manuscript length and production cadence before choosing a tier.

Platforms

Audibloom runs on the web, so its listed platform is browser-based rather than a desktop or mobile app.

Who it's for

Audibloom is a strong fit for indie authors, KDP publishers, and small presses that want character casting, chapter-level revision, and commercial rights without royalty sharing. It is less suitable for authors who require M4B packaging now, or who want to publish beyond the free tier without a watermark but produce only a small amount of audio each month.

Pros and cons

• Pro: Separate chapter editing and rendering make targeted revisions practical.
• Pro: PDF cleanup and EPUB structure preservation reduce common import problems.
• Pro: Paid plans retain all royalties and grant commercial distribution rights.
• Con: Current exports are chapter-level MP3s; M4B packaging is not yet available.
• Con: Free generation is limited to five minutes monthly, and downloads carry a watermark.
• Con: Creator's two-hour monthly quota may constrain longer or frequent productions.

Verdict

Choose Audibloom if you want a chapter-editable, multi-voice audiobook workflow and commercial rights without royalty sharing. Its strongest case is the combination of manuscript cleanup, character casting, and independently renderable chapters. Choose another tool if M4B packaging is essential, or if the free tier's five-minute watermarked preview is not enough to judge your project.
