Chat with millions of AI characters or build your own
Browse and chat with a vast library of community and official characters across genres and fandoms.
Design a character's look, backstory, personality and voice, then share it with the community.
Talk with characters using voice chats and Voice Notes, not just typed messages.
Long-form, in-character conversations built for storytelling and immersion rather than quick answers.
Your own dedicated GPU workspace for open-source AI art and video
Launch a private, dedicated GPU machine in roughly 90 seconds with no installs, drivers or local hardware required, and drive it from any device including a phone.
Run industry-standard open-source interfaces side by side — Automatic1111, ComfyUI, Fooocus, Forge and Kohya — and launch multiple machines at once for parallel work.
Pull models, checkpoints, LoRAs, embeddings and textual inversions from Civitai, Hugging Face or your own drive in one click, and add any extensions or custom nodes.
Each machine is yours alone, with up to 200 GB of persistent private storage, an auto-stop timer, and file access without launching a machine.
