About

Lemon is an AI voice agent designed to turn natural speech into completed tasks across any application, enabling users to execute work without typing or switching between tools. It operates through a simple interaction model where users press a key, speak their intent, and the system carries out actions such as replying to messages, drafting documents, performing research, or delegating tasks directly within their current workflow. Unlike traditional voice-to-text tools, Lemon focuses on “voice-to-action,” meaning it interprets intent and produces finished outputs rather than just transcribing speech. It is built to eliminate context switching, allowing users to stay in the same tab while interacting with emails, documents, or other apps, significantly reducing interruptions and improving focus. It supports features such as instant search, document creation, tone editing, ideation, and dictation, functioning as a second brain that accelerates everyday knowledge work.

About

StepAudio 3 is StepFun’s next-generation audio model family, built to understand, generate, and interact through voice, sound, and music. The lineup includes StepAudio 3 Realtime for natural full-duplex conversation, StepAudio 3 ASR for speech recognition, StepAudio 3 TTS for speech synthesis, StepAudio 3 Gen for general-purpose audio generation, and StepAudio 3 Music for long-form music creation. Realtime is designed around a continuous listen-converse-think-act loop, understanding not only words but also hesitation, laughter, emotion, pauses, backchannels, and interruptions. It can think while speaking, reason through harder questions without breaking conversational flow, and use tools to complete tasks once it understands the user’s intent. StepAudio 3 Gen unifies zero-shot TTS, voice design, vocal generation, sound effects, music, and mixed audio generation within one framework, while StepAudio 3 Music supports text-controlled songs, instrumentals, vocal arrangement, and more.
