Interview with SoulBox Founder
Your Bots. Your Voice. Your Rules.
SoulBox is a platform for creating AI-powered bots with real personalities, custom voice cloning, and multi-bot group conversations. Every bot speaks with a unique cloned voice through real-time text-to-speech.
Custom Bot Personalities
Design bots with distinct personas, backstories, moods, and behavioral traits. Each bot remembers past conversations and evolves over time.
Voice Cloning & TTS
Upload or record a voice sample and SoulBox clones it. Every bot speaks with its own unique voice through advanced text-to-speech synthesis.
Group Conversations
Put multiple bots in a room together. They debate, joke, argue, and riff off each other in real-time with full audio playback.
One-on-One Chat
Have private conversations with any bot. Text or voice input, real-time TTS responses, karaoke-style word highlighting, and message replay.
Public Bot Community
Share your bots publicly or discover bots created by others. Browse the community library and add them to your conversations.
NSFW Controls
Full content control per bot and per conversation. Enable or disable explicit content with hard-enforced LLM guardrails.
From Idea to Conversation in Minutes
Create a Bot
Give it a name, personality, age, gender, mood, and backstory. Pick an AI model.
Clone a Voice
Upload a voice sample or record one. SoulBox clones it for text-to-speech synthesis.
Start Talking
Chat one-on-one or drop multiple bots into a group conversation with a topic prompt.
Listen & Share
Every response is spoken aloud with the cloned voice. Share bots publicly or keep them private.
Every Bot Has Its Own Voice
SoulBox uses advanced multi-provider text-to-speech with automatic failover. Upload a voice sample, normalize the audio, and your bot speaks with that exact voice. Volume normalization ensures consistent levels across all bots.
