Cross-platform desktop app that transcribes your voice into any text field using a keyboard shortcut, with all processing done locally on your machine.

Handy is a desktop speech-to-text tool that works with any text field on your computer. Press a keyboard shortcut, speak, release, and your words appear wherever your cursor is. No cloud. No subscription. No copy-paste step.
It's built for people who want voice input without giving up privacy. Unlike browser extensions or cloud-based dictation tools such as VoiceTypr or VoiceInk, Handy processes everything locally. Your audio never leaves your machine.
The feature set is deliberately minimal:
Setup is light. A small icon appears in your system tray or menu bar when transcription is active, so you always know when it's listening.
The tool is cross-platform, running on macOS, Windows, and Linux. It does one job well. There's no dashboard, no account, and no settings beyond what you actually need to change.
For anyone who types a lot and wants a faster, hands-free alternative for drafting messages, filling forms, or writing notes, Handy covers that use case without adding complexity.

Dictation app powered by OpenAI Whisper and NVIDIA Parakeet. Runs locally on macOS, Windows, and Linux with zero data retention and 100+ language support.

OpenWhispr is a voice dictation tool that transcribes speech directly into any app on your computer. It runs on macOS, Windows, and Linux, and works entirely offline using local AI models. For anyone who types a lot, whether drafting emails, chatting in Slack, or writing code in Cursor, it's a faster alternative to the keyboard.
The core pitch is speed and privacy together. Speaking is roughly three times faster than typing, and OpenWhispr doesn't trade your data for that speed. Audio processed locally never leaves your device. Even when using cloud processing, audio isn't stored or logged after transcription.
Key capabilities:
You can bring your own OpenAI API keys for unlimited cloud transcription at no extra cost beyond what OpenAI charges. The free tier includes 2,000 words per week and five hours of meeting recordings per month. Paid plans add unlimited transcription, device sync, and an agent mode for chatting over your recorded data.
For teams comparing it to tools like Superwhisper, the main differentiator is the combination of fully local processing, an auditable open-source codebase, and cross-platform support. The code is public on GitHub, so the privacy claims are verifiable rather than just policy language.
