VoiSistant

Product Introduction

1. VoiSistant is a macOS menubar application that converts spoken language into polished text or real-time translations using AI enhancement and Microsoft’s text-to-speech (TTS) technology. It operates locally by default for privacy and integrates seamlessly with cloud-based large language models (LLMs) for advanced text refinement.
2. The core value of VoiSistant lies in streamlining voice-to-text workflows by eliminating manual editing, reducing app-switching, and ensuring data privacy through local processing for TTS and optional cloud integration for AI enhancements.

Main Features

1. VoiSistant provides lightning-fast speech-to-text conversion with automatic punctuation, smart formatting, and support for multiple languages, enabling users to generate draft-quality text in seconds.
2. The app offers one-tap AI refinement using customizable LLM providers (OpenAI, Gemini, Ollama, etc.) to fix grammar, adjust tone, and optimize style, ensuring text aligns with professional or personal communication standards.
3. Integrated Microsoft TTS delivers natural-sounding voice playback with adjustable voices, while global hotkeys and auto-paste functionality allow direct insertion of processed text into any application without manual copying.

Problems Solved

1. VoiSistant addresses the inefficiency of manual text editing and workflow disruption caused by switching between voice recording, translation apps, and text editors.
2. The product targets professionals, multilingual communicators, and content creators who require rapid, polished text output from voice inputs while maintaining control over privacy and data processing locations.
3. Typical scenarios include drafting emails with AI-enhanced clarity, translating customer queries in real time during multilingual meetings, and generating error-free meeting notes through voice dictation with automated formatting.

Unique Advantages

1. Unlike competitors, VoiSistant supports hybrid processing by allowing users to choose between local TTS for privacy and cloud-based LLMs for advanced AI features, avoiding vendor lock-in.
2. Its pipeline functionality enables sequential post-processing actions such as translating text, saving to history, and triggering Apple Shortcuts, which most voice assistants lack.
3. Competitive advantages include macOS-native menubar integration for instant access, compatibility with both proprietary and open-source LLMs, and offline-capable TTS using Microsoft’s high-quality voices without requiring constant internet connectivity.

Frequently Asked Questions (FAQ)

1. Does VoiSistant store or transmit voice data to third parties? VoiSistant processes speech-to-text and TTS locally by default, with cloud LLM usage being optional and configurable; no data is collected or shared unless explicitly enabled by the user.
2. Which languages are supported for translation and TTS? The app supports translation between English, Italian, Spanish, Russian, and other major languages, with Microsoft TTS offering over 100 natural voices across multiple dialects.
3. Can I use VoiSistant without an internet connection? Local speech-to-text and TTS functions work offline, but AI refinement and translation require internet access if using cloud-based LLMs like OpenAI or Gemini.
4. How do I switch between different LLM providers? Users can select and configure LLM providers (OpenRouter, LM Studio, etc.) directly in the app’s settings, with API key integration for seamless switching during text processing.
5. Are custom TTS voices supported? VoiSistant utilizes Microsoft’s prebuilt neural voices for TTS and does not currently support custom voice models, but users can adjust speech speed and pitch within the app.
