Private Mic
This is a privacy-first voice capture and knowledge management solution that converts spoken conversations into searchable insights. Combining custom embedded hardware with AI-powered transcription and summarization, it enables secure recording, organization, and retrieval of voice notes, meetings, and personal recordings while ensuring complete data ownership.
About Private Mic
PrivateMic combines a custom ESP32-based recording device with a companion mobile application to create a seamless voice-to-knowledge workflow. Users can capture audio with a single button press, while the system securely transfers recordings to the mobile application over BLE or WiFi for processing.
The platform leverages advanced AI services for speech-to-text transcription and intelligent summarization, helping users quickly review and understand key information from their recordings. To ensure maximum privacy, all audio files and generated summaries are automatically stored in the user’s personal Google Drive account, with no data retained on developer-controlled servers.
Beyond simple recording, PrivateMic provides an intelligent search and question-answering experience across historical recordings, allowing users to retrieve information and uncover insights from past conversations. The solution serves as a secure alternative to traditional voice assistants for professionals, researchers and individuals who prioritize data privacy and ownership.
The project showcases expertise in embedded systems, AI integration, mobile application development and privacy-focused cloud architectures.
