SpeakoFlow lets you dictate into other apps and ask an AI assistant for help without leaving your work. It's for people who want voice typing, spoken conversations and meeting notes with processing on their own computer.

Waves Clarity Vx DeReverb is a proprietary neural audio plug-in for reducing room reverberation in recorded speech and singing. It is for music producers, podcast creators and dialogue editors who need to reduce unwanted acoustics while retaining the vocal performance.

Revornix is an AI knowledge workspace for people who collect articles, research papers and recordings and want to ask questions across their library. It connects saved material in a personal knowledge graph and uses those relationships to inform its answers.

Kokoro Clipboard TTS reads selected or copied text aloud on Windows and macOS using Kokoro-82M. It's for people who want to listen to text across desktop apps while keeping it private. Speech generation works offline, and both clipboard text and audio stay on your machine. It doesn't require an account or API key, and it has no telemetry.

Podcastfy turns source material into podcast-style audio conversations for creators and developers. It's an alternative to NotebookLM's podcast feature for people who want to customize the conversation or include podcast generation in their own software.

audio.cpp runs audio models locally for developers building speech tools and people generating or processing audio on their own hardware. It brings multiple audio tasks into one C++ runtime built on ggml.

Memo AI turns audio and video into transcripts, translated subtitles and notes for people reviewing interviews, meetings or podcasts. Speech recognition works offline, and speaker identification runs locally.

WhisprStream turns speech into text at your cursor in other Mac apps. It's for people who dictate notes, email, or coding prompts and want speech processing to stay on their own computer.

sonible smart:gate is a proprietary audio gate plug-in for people mixing music or cleaning up recorded tracks on macOS and Windows. Its AI processing detects a chosen sound source, such as vocals, electric guitar or piano, rather than relying only on volume to decide when the gate opens. That helps when the sound you want to keep changes level or a competing instrument is louder.
