When 15.ai went offline, it left a big gap for anyone who relied on it for realistic, character-driven voice generation. I was right there with you, searching for a tool that could deliver those smooth, emotional, character-style voice-overs without a hassle. After it went offline, I started testing every alternative I could get my hands on.
In this article, I’ll walk you through six of the best 15.ai alternatives I’ve personally tried. Some offer ultra-realistic voice cloning, others bring the fun of animated character voices, and a few even let you create your custom voices.
If you’re looking for a new go-to tool for AI voiceovers, here are the top 6 I discovered.
What is 15.ai and why are we looking for alternatives?
15.ai was a beloved AI voice generator known for creating eerily realistic voices of fan-favorite characters like SpongeBob, GLaDOS, and Twilight Sparkle. It gained a cult following thanks to its emotional depth, fast generation, and uncanny ability to mimic character tones using minimal training data. Just type your text and you’d get high-quality, expressive voice lines within seconds.
However, despite its popularity, 15.ai went offline in September 2022 and remained unavailable for nearly three years. It finally relaunched in May 2025 as 15.dev, but many users remain cautious about depending on it again due to the long hiatus and lack of updates during that period.
That’s why I decided to explore more stable and actively maintained alternatives. If you’re searching for tools that can match or even outperform what 15.ai offered—whether for voiceovers, content creation, or just for fun—here are six standout options I personally tested and reviewed.
