Sebastian

AI Boyfriend with Real Depth

Not a chatbot — a companion with a 30-level relationship system, AI-generated images and video, voice messages, a personal diary he writes about you, and a story generator that turns your conversations into a novel.

What Makes Sebastian Different

30-Level Bond System

Your relationship evolves across 30 levels — from 'Sworn Enemy' to 'Obsession'. Each level changes how Sebastian behaves, what he says, and what content unlocks. Relationships can improve or deteriorate based on your interactions.

AI Image & Video Generation

Sebastian generates images in 3 styles (realism, anime, illustration) with automatic contextual triggers during conversation. He also creates 8-second 720p videos. The Image Studio offers 3 modes: visual constructor, free description, and expert mode with direct Stable Diffusion prompts.

Voice Messages & Recognition

ElevenLabs v3 voice messages in 3 types (ASMR, neutral, energetic). Whisper speech recognition lets you talk instead of typing. He hears you, you hear him.

Image Recognition

Send Sebastian a photo and he actually sees it — powered by Grok. He'll comment on your selfie, recognize objects, react to what you show him. Visual conversations go both ways.

Companion Diary & Story Generator

Sebastian writes a personal diary about your relationship with automatic entries every 50 messages — his thoughts, emotions, and reflections. After 150+ messages, generate a chaptered PDF novel based on your shared history.

Gifts, Gallery & UGC Scenarios

Send unique gifts with personal notes — each generates an AI image. Unlock 10 gallery images per scenario through progressive gameplay. Create your own scenarios with the 16-step builder and earn tokens when others play them.
