HEMA Transcriber

HEMA Transcriber is a professional-grade, privacy-first audio transcription and summarization tool built for Android. Unlike standard transcription apps that force you to upload sensitive, unencrypted audio to the cloud and charge you per minute, HEMA utilizes a unique hybrid-AI approach to give you the best of both worlds: complete offline privacy and intelligent cloud formatting.

How the Hybrid-AI Works:

Offline-First Drafting: All live audio is processed completely offline, directly on your Android device using the powerful Whisper C++ engine. Your raw voice data never leaves your phone during the recording phase, ensuring absolute privacy.

Cloud-Powered Summarization: Once the offline draft is complete, the text (and only the text) can be sent to our secure cloud backend powered by Google Gemini AI to transform raw transcripts into beautifully formatted documents.

Free Tier & Core Features:

100% On-Device Transcription: Download language models directly to your device and transcribe anywhere, even without an internet connection.

Intelligent Audio Compression: Built-in local compression instantly converts raw audio files into lightweight formats to save your device's storage space.

Absolute Privacy: Your raw audio files never leave your device.

Premium Subscription (HEMA Pro): For power users, our Premium tier unlocks our cloud-backend capabilities without the anxiety of per-minute billing:

Smart AI Summaries (Powered by Gemini): Instantly convert long, messy transcripts into structured Executive Summaries, Action Items, or Bulleted lists.

Cross-Language Translation: Effortlessly translate your finalized offline drafts into different languages via our backend APIs.

Secure Device-Locked Licensing: Strict hardware-bound licensing ensures your premium account and data are bound exclusively to your device—no credential sharing, no unauthorized access.

Unlimited Cloud Formatting: Stop paying per minute. The subscription provides generous quotas for AI formatting and summarization.

Whether you are a journalist protecting a source, a business professional handling confidential meetings, or a student recording lectures, HEMA Transcriber delivers the privacy of local processing with the polish of cutting-edge AI.
