nex-voice

Voice note transcription and intelligent action item extraction for capture and organization of verbal communication. Record and transcribe voice notes, voice messages, and meeting recordings in Dutch and English using OpenAI Whisper with selectable model quality (tiny to large). Automatically extract structured action items from transcripts including tasks (moet, must), reminders (vergeet niet, don't forget), scheduled calls, email actions, meetings (afspraken), decisions, and deadline-based items. Full-text search across all transcripts to find past conversations and action items by keyword. Manage extracted actions with completion tracking, priority levels, and due date assignment. View pending and overdue action items to stay on top of commitments. Optional LLM integration for intelligent action extraction and transcript summarization. Perfect for busy professionals, meeting attendees, and business owners who prefer speaking notes over typing and need to convert voice into organized action items and searchable records. All audio files and transcripts stay secure on your machine.
