VoiSistant

Overview

VoiSistant is a native macOS menubar application launched on October 27, 2025, that transforms speech into polished text through AI-powered refinement, instant translation, and natural voice playback. Rather than competing with macOS’s built-in dictation (which processes up to 60 seconds per session and requires manual formatting) or full cloud-based transcription services, VoiSistant addresses a specific productivity gap: converting casual voice input into production-ready text that can be pasted directly into emails, documents, messages, and other applications with minimal manual editing.

The platform prioritizes privacy through local-first architecture—speech-to-text processing occurs on-device using Apple’s native speech recognition, while optional cloud integrations (OpenAI, Gemini, Ollama, LM Studio, OpenRouter) enhance text through AI refinement only when explicitly enabled by users. This hybrid approach enables privacy-conscious professionals to use AI enhancement without requiring cloud processing of voice data by default.

Developed by IEVGEN KHOPTIAR under TrendsLab, VoiSistant targets creators, multilingual professionals, and busy teams who need rapid voice-to-text conversion without application switching or extensive post-processing. The app is available free on the Mac App Store (App ID: 6749696981) and requires macOS 14.6 or later.
