AI Voice Recorder for Field Workers
AI Tools
VoiceField is a PHP 8.x + MySQL-based AI voice recorder designed for field service workers including plumbers, electricians, HVAC technicians, mechanics, and cleaning teams. The application allows field workers to record or upload voice notes directly from any mobile browser without installing an app. Once recorded, the audio is automatically transcribed using AI speech-to-text services such as OpenAI Whisper, AssemblyAI, or Vosk, and then processed by an AI model such as Google Gemini or Anthropic Claude to extract fully structured job data including client name, address, phone number, job type, work performed, materials used, action items, urgency level, and follow-up date.
AI Voice Recorder for Field Workers
VoiceField is an AI-powered voice recording and job documentation system built for tradespeople and field service professionals. Field workers record or upload a voice note from any mobile browser — no app download required — and the system automatically transcribes the audio and uses AI to extract a fully structured job record: client name, address, job type, work performed, materials used, action items, urgency level, and follow-up date. The complete job record is saved to a searchable dashboard and can be exported as a PDF report, CSV, or JSON for CRM integration. Coderobotics offers this script with complete source code, no encryption and no domain restrictions.
The Problem It Solves
Field workers spend valuable time after every job typing up notes, filling in job sheets, and updating records — often from memory, hours later. VoiceField eliminates that entirely. Workers speak naturally at the job site, and AI handles all the admin.
