High-Accuracy Voice Input Windows App Usable in Any Software or Browser (Powered by Whisper AI | Website and Payment Features Included)
オンラインBusiness
Business description
A voice input desktop application for Windows. With a global shortcut (any key you set), it enables voice input into any application or browser. It adopts OpenAI's Whisper-large-v3 to achieve high-accuracy Japanese recognition.
It can greatly cut typing time in your existing PC work. In addition, as AI users rapidly increase and opportunities for long-form input grow, demand for this app, which reduces keyboard-input time, is expected to rise further.
Not only the desktop app itself, but also the official website/landing page, user dashboard, and Stripe payment features are all implemented, so it can launch immediately once marketing begins.
【Main Features】
- Start recording instantly with a global shortcut
- Automatic silence detection (stops automatically when you finish speaking)
- Automatic text input
- Custom shortcut settings
- History saving
【Current Revenue Model】
- Free plan: up to 10 times per day (no registration required)
- Paid plan: unlimited use for ¥1,000/month
- Fully integrated Stripe payments, with a 7-day free trial
【Target Market】
Because it can be used across all apps and browsers, the target audience is limitless:
- Programmers (vibe coding in VS Code, IntelliJ, etc.)
- Writers and bloggers (writing articles in Word, Notion, Google Docs, etc.)
- Businesspeople (meeting minutes and email replies in Gmail, Slack, Teams, etc.)
- Students (writing reports and lecture notes in any editor)
- Customer support (reply work in business systems, chat tools, etc.)
- Creators (idea notes in Figma, Adobe products, etc.)
【Market Environment】
Overseas there are strong competitors such as Whisper Flow and SuperWhisper, but the voice-input market itself is still in its early days, with enormous room to grow. The Japanese market in particular is completely blank, and awareness of overseas products is nearly zero outside the AI-interested segment. At ¥1,000/month (about $7), less than half the price of competitors, plus a low entry barrier thanks to a Japanese UI and support, we believe there is a great opportunity.
【Current Status】
Development is complete, but marketing and user acquisition have not yet been carried out.
As a result, the current user count and revenue are zero, but the product itself is complete and ready to launch immediately.
