DescriptionClownfish Voice Changer is a free Windows voice-effects application from developer Bogdan Sharkov, whose official site identifies Shark Labs, Sofia. It changes audio at the microphone capture-device level, so applications using that configured input can receive the effect. Current main download packages target Windows 10 and 11. The main app includes pitch and character effects, a sound player, a music player, keyboard controls and VST plugin support. The base effect list should not be confused with a library of AI-generated voices. Its documented VC Client connection uses a separate external voice-conversion tool; the external software, model setup and permissions are additional considerations. Installation requires administrator rights and choosing the capture device to modify. The official instructions say the default capture device is selected initially, with other devices available through Setup. Choose the installer matching the operating system and the VST variant you need. Enable a voice effect, use Hear microphone to preview it, and test the actual microphone in your call or game before relying on the result. Clownfish's separate Terminal Edition routes an audio input to a chosen output and lists Windows, macOS and Linux downloads. It requires additional software to create a virtual audio device. Those downloads do not mean that the main Windows graphical app has the same interface and setup on Mac or Linux. The official site includes a free software license notice permitting use and redistribution subject to its conditions. That software permission does not automatically license outside plugins, voice models, music or sounds. Use the official download page for the current edition and setup notes. Compare Voicemod for a desktop voice catalog and soundboards with Free and PRO access; Clownfish is an alternative when a Windows device-level effects workflow fits your needs.LLMStack is a source-available builder for AI agents, workflows and chatbots that combine model calls with your own data. Its visual builder can chain multiple models and connect data sources, making it more suitable for assembling an application or process than for simply opening a personal chat app. The project documents deployment on your own infrastructure and points to Promptly as its hosted offering. Supported data inputs include documents, websites and connected sources such as Google Drive and Notion. The builder provides preprocessing and vectorization for retrieval workflows. Apps can be shared publicly or with selected people, and viewer and collaborator permissions control access to shared work. The repository also documents HTTP API access and Slack or Discord triggers. Plan for infrastructure, model-provider usage, credentials and permissions as separate decisions. Installing a self-hosted builder does not make externally hosted models free or keep every data request local. Start with a limited workflow and representative documents, review the generated output, and confirm the permissions required by each connected source before expanding access. Compare AnythingLLM when a document-chat workspace is the main need; LLMStack is oriented toward composing the application and its workflow.
