SonifAi is an AI-powered platform that converts any text into professional audiobooks. Features include: natural-sounding AI voices with emotional expression, automatic translation between 35+ languages, AI-generated background music matching your content mood, AI-generated cover art, multi-voice narration with unique voices for each character, and the ability to publish and share your creations with the world.

How many languages does SonifAi support?

SonifAi supports 35+ languages including English, Spanish, French, German, Russian, Japanese, Chinese, Korean, Arabic, Hindi, Portuguese, Italian, Polish, Turkish, Dutch, Swedish, and many more. You can translate content from any language to your preferred output language - for example, read a Japanese manga in English or a Russian novel in Spanish.

How long does it take to create an audiobook?

Most audiobooks are generated in just a few minutes. A typical book chapter (5,000-10,000 characters) takes 2-5 minutes to process. Premium users enjoy up to 5x faster generation through parallel processing. The process includes text analysis, optional translation, voice synthesis, soundtrack generation, and cover art creation - all fully automated.

Can I download my audiobooks?

Premium users can download their audiobooks as MP3 files with no DRM or restrictions. You can download the full audiobook with soundtrack, the soundtrack only, or the voice-only version. Standard users can stream their content online. Premium status is automatically granted when you spend $50 or more in a calendar month.

How does pricing work?

SonifAi uses pay-as-you-go pricing with no subscriptions required. Simple Voice costs $0.10 per 1,000 characters (~$10 for an average book). Theatrical Voice with emotional expression and multi-character voices costs $0.18 per 1,000 characters (~$18 for an average book). Translation adds $0.03 per 1,000 characters. Volume discounts available: 10% off at 100K+ chars, 15% at 250K+, 20% at 500K+, and 25% at 1M+ characters.

What is Premium status?

Premium is automatically granted when you spend $50 or more in a calendar month and lasts for 30 days. Premium benefits include: MP3 downloads, 5x faster generation, first regeneration free, unlimited playlists, private sharing with access codes, permanent content storage, verified creator badge, and the ability to follow other creators playlists.

What is the difference between Simple Voice and Theatrical Voice?

Simple Voice provides clear, neutral narration ideal for technical documentation, articles, and non-fiction content. Theatrical Voice offers dramatic, emotional voice acting with the ability to assign unique voices to different characters - perfect for fiction, novels, and content with dialogue. The AI automatically detects characters and assigns appropriate voices.

What types of content can I convert?

You can convert virtually any text content: novels, book chapters, short stories, fanfiction, articles, blog posts, research papers, scientific documents, comics and manga text, newsletters, personal notes, study materials, scripts, and more. Maximum input is 100,000 characters per project. Foreign language content can be automatically translated before conversion.

Can I share my audiobooks with others?

Yes! You can publish your audiobooks to the SonifAi marketplace where anyone can discover and listen. Standard users can publish publicly. Premium users can also use private sharing options: access codes for specific groups, or private links for individual sharing. You can control whether others can download your content and build a following of subscribers.

What if I am not satisfied with the result?

You only pay after confirming you are happy with your audiobook. If not satisfied, you can request a regeneration (first one is free for Premium users, 50% cost for standard users) or get a full refund to your balance. We want you to love your audiobook before committing to pay.

How does the AI soundtrack work?

SonifAi analyzes your text to understand the mood, genre, and emotional tone, then generates original background music that matches your content. The soundtrack is unique to your audiobook - no generic stock music. You can preview with or without soundtrack and adjust the volume balance between voice and music.

Is there a subscription option?

SonifAi primarily uses pay-as-you-go pricing with no mandatory subscriptions. However, power users who bring their own API keys can access an Unlimited plan for $99/month. Most users find the pay-as-you-go model more cost-effective - you only pay for what you create with no monthly commitments.
