Supertone vs PirateDiffusion

Supertone builds voice tools for creators, streamers, and post-production teams. The lineup spans Shift, a real-time voice changer for gaming and V-tubing, plus Clear and Air, audio plugins that clean dialogue and match ADR to production tracks. The company also ran cloud Play, API, and Voice Builder services, which shut down on August 31, 2026, while Shift, Clear, and Air continue under new ownership.

Most voice AI vendors sell text-to-speech APIs. Supertone splits the problem across use cases instead. Its neural models are trained on large voice datasets, which is where the heavy science sits. Shift targets sub-second latency for live voice conversion without a GPU, while Clear and Air are offline DAW plugins built for film and TV workflows.

Streamers and V-tubers use Shift to swap personas in Discord, VRChat, or live streams. Post-production engineers reach for Clear to strip noise and reverb from location dialogue, and Air to make replacement lines sit in the same acoustic space as the original take.

Shift runs on Windows 10+ and macOS 10.14+ with a free tier that unlocks 100+ voices through monthly credits. Clear sells for a one-time $69 license and Air for $99, both available as AU, VST3, and AAX plugins with native Apple Silicon support.

PirateDiffusion runs as @piratediffusion_bot on Telegram and generates images, video, music, and LLM chats from slash commands. Type // for guided skills, /render for manual Stable Diffusion prompts, or /wf workflows to call models like Wan 2.2, LTX 2.3, Hunyuan, FLUX 2, and SDXL without opening a desktop UI. A linked Graydient web studio at my.graydient.ai handles inpainting, file archives, and visual workflows the chat interface cannot.

Credit-based image apps meter every render. PirateDiffusion advertises unlimited generations on paid plans with no token wallet, bundling the Telegram bot with Graydient's browser webUI. That makes it better for high-volume Stable Diffusion experimentation than services that charge per image, though free accounts show ads and stay in a restricted mode until Patreon activation lifts NSFW limits.

Telegram creators, hobbyists, and community groups use PirateDiffusion for quick mobile renders, custom PollyGPT character bots, and multi-step video extensions via /wf commands. Setup starts with /start and /debug in Telegram plus a Graydient account; Plus members unlock additional LLM model switching beyond the default Llama3 /llm command.
