Private Offline Voice Input

A desktop dictation tool that defaults to local recognition and handles Chinese-English mixing

Problem

Users asking for the best voice input method list two hard requirements: privacy protection and solid Chinese plus English recognition. Mainstream options either upload audio to the cloud or struggle with Chinese technical vocabulary and mixed-language speech, rarely satisfying both.

Solution

A desktop dictation tool that defaults to a local Whisper-class model, keeping audio on-device. It optimizes prompts and lexicons for Chinese-English mixing and developer terms, with a custom dictionary. Users can opt into a cloud model for higher accuracy, but the default path is fully offline.

Users

Privacy-conscious bilingual users, developers, writers, and sensitive professions like journalists and lawyers

MVP

Offline local transcription; global hotkey to start dictation; Chinese-English mixing tuned; custom terminology dictionary; one-click insert at cursor

Revenue

One-time purchase plus optional subscription for cloud high-accuracy mode and dictionary sync

Why now

Local speech models now run well on consumer hardware, privacy concerns keep rising, and mainstream IMEs remain cloud-first; a solo dev can win on bilingual mixing and developer lexicons
