Why Online TTS is Better Than Desktop Software

Cloud-powered AI voice on any device, always up to date

No Installation, No Updates

Desktop TTS software requires downloading large installers, managing updates, and troubleshooting compatibility issues. TTS.ai runs in your browser — always the latest version, always compatible, zero maintenance. Open a tab and start generating.

  • No 500MB+ downloads
  • No driver or dependency issues
  • Automatic updates — always the latest models
  • Works instantly on any computer

GPU Power Without a GPU

Running neural TTS models locally requires an expensive NVIDIA GPU with 8-24GB of VRAM. With TTS.ai, the AI processing happens on our dedicated GPU cluster (4x Tesla P40, 96GB VRAM). You get studio-quality voice synthesis from a budget laptop, a Chromebook, or even a phone.

  • No GPU required on your device
  • Works on Chromebooks, tablets, and phones
  • Same quality from any device
  • 4x Tesla P40 GPUs handle the processing

Works on Every Device

Desktop software runs on one computer. TTS.ai works on every device you own — start a project on your laptop, continue on your tablet, listen on your phone. Your generation history and settings sync across devices when you create a free account.

  • Desktop: Chrome, Firefox, Safari, Edge
  • Mobile: iOS Safari, Android Chrome
  • Tablets and Chromebooks
  • Synced history across devices

19+ Models in One Place

Installing even one TTS model locally requires hours of setup — Python environments, CUDA drivers, model weight downloads. TTS.ai gives you instant access to 19+ models through one web interface. Switch between Kokoro, Bark, Tortoise, and CosyVoice2 with a single click.

  • No Python/CUDA/PyTorch setup
  • No multi-gigabyte model downloads
  • Switch models with one click
  • New models added automatically

Často kladené otázky

Common questions about online text to speech

No. TTS.ai runs entirely in your browser. Our GPU servers handle all AI processing and deliver audio directly to your browser. You do not need to install any software, plugins, or extensions.

TTS.ai works in all modern browsers: Chrome, Firefox, Safari, Edge, Opera, and Brave. It works on Windows, macOS, Linux, ChromeOS, Android, and iOS. Any browser that supports HTML5 audio playback is compatible.

Yes. The interface is fully responsive and works on smartphones and tablets. Generate speech, preview voices, and download audio from your mobile device with the same features and quality as the desktop experience.

Yes, and often better. Our GPU servers run the same open-source models that desktop users install locally, but with powerful NVIDIA Tesla P40 GPUs. You get the same or better quality without managing GPU drivers, Python environments, or model downloads.

Kokoro generates audio in under 2 seconds for typical text lengths. Most models deliver results within 5-15 seconds. Speed depends on text length and model complexity. Our GPU cluster processes requests in parallel for consistent performance.

Free models (Kokoro, Piper, VITS, MeloTTS) have no daily or monthly limits. Without an account, there is a rate limit of 3 generations per hour. Creating a free account removes this restriction. Premium models require credits.

No. You can generate speech immediately without creating an account. An optional free account gives you higher rate limits, generation history, voice favorites, and access to premium models. Basic TTS is always available without signup.

Yes. All models use permissive open-source licenses (MIT, Apache 2.0) that allow commercial use. Audio generated through TTS.ai can be used in YouTube videos, podcasts, apps, products, and advertisements without licensing fees.

Yes. Text submitted for TTS generation is processed and immediately discarded. We do not store, analyze, or share the content of your text inputs. Generated audio files are temporarily cached for download and then automatically deleted.

Yes. Use our REST API to add TTS functionality to any website or application. The API accepts text input and returns audio, allowing you to build custom TTS interfaces. API documentation with code examples is available at /api/.

Each generation supports up to 500 characters. For longer texts, split at natural sentence boundaries and generate multiple audio files. The API supports automated chunking for processing texts of any length programmatically.

No. Online TTS requires an internet connection since our GPU servers process the audio generation. For offline use, download generated audio files as MP3/WAV while connected, or self-host open-source models on your own hardware.
