Generate Long-Form Audio
Without Limits

Transform large transcripts into high-quality audio tracks using AI-powered text-to-speech. Break through platform limitations with intelligent chunking.

The Problem with Long-Form TTS

Most text-to-speech platforms have strict limitations that prevent you from generating high-quality audio for long transcripts.

5000 Character Limit

Platforms like Elevenlabs, GenAIpro, and Minimax.io restrict single requests to 5000 characters, making it impossible to process large transcripts in one go.

Quality Degradation

Even when approaching the limit, audio quality noticeably decreases. You're forced to compromise on quality or manually split your content.

We intelligently break down your large transcripts into optimal chunks, process them seamlessly, and merge them into a single high-quality audio file.

Smart Chunking

Automatically splits your transcript at optimal points to maintain context and quality

Parallel Processing

Processes multiple chunks simultaneously for faster generation times

Seamless Merging

Combines all audio parts into a single, high-quality final file
