The fastest way to dictate text without giving up control of your data

OiPer is a privacy-first voice-to-text desktop app built for speed and flow. Hold your global hotkey to record, release to transcribe, and watch text instantly appear in your active application.

Quick Recording and Transcription

- Global hotkey activation with simple press and release workflow
- Instant text injection into whichever application is active
- Optional text cleanup through local or online processing

Privacy-First Architecture

- Transcription runs locally on your machine
- Audio and activity logs remain on-device
- No outbound data transfer without explicit user choice

Flexibility and Control

- Choose backend mode: auto, cpu, or gpu
- Connect your preferred online provider with custom base URL
- Support for multiple LLMs for highly accurate specialized text

Privacy and Security

Local processing keeps transcription, logs, and audio on-device by default. Nothing leaves your machine unless you explicitly enable an online provider.

Online optimization is optional, API key based, and easy to turn off whenever you choose.

Settings and Configuration

- Speech model downloads and model-size management
- Backend switching for auto, cpu-only, or gpu acceleration
- Base URL, API key, and model name configuration
- Local or online text optimization selection
- Advanced LLM transcription for specialized terminology
