Voice typing that actually works — everywhere

Most voice tools break on Gmail, Notion, and React apps. STTBox injects into the page's native input events, so it works where others fail.

🌐
Works on every website
Native input event injection bypasses React, Vue, and Angular — text lands where your cursor is on any site.
🤖
AI autocorrect & smart punctuation
On-device language model fixes homophones and grammar before text hits the page. Say "period" to insert a period.
🌍
50+ languages
English, Chinese, Japanese, Spanish, French, German, Arabic, Hindi, Korean, and 40 more — switch instantly from the toolbar.
⌨️
Keyboard shortcut toggle
Press Alt+V (or your custom shortcut) to start and stop. No clicking, no popups — just speak and type.
🔒
Privacy-first architecture
Audio is processed by Chrome's built-in speech API and never leaves your device. No audio storage, no data brokers.
✨
Context-aware tone
Detects LinkedIn, email, Slack, code editors — and adjusts formality, capitalization, and spacing automatically.

What people are saying

★★★★★
"I switched from Voice In after hitting the daily limit for the third time. STTBox has no limit and it just works. The AI correction on Notion is actually impressive — it catches most of my speech errors before I even notice."

Content Writer, Chicago
★★★★★
"I code and write documentation all day. The context detection is the killer feature — it switches from casual tone in Slack to technical in GitHub automatically. I didn't even set it up, it just worked."
KT
Kenji T.
Senior Engineer, Tokyo
★★★★★
"Hablar es tres veces más rápido que escribir para mí. STTBox en español es excelente, entiende el contexto y prácticamente no comete errores. Perfecto para mis correos en LinkedIn."

★★★★★
"I have RSI and typing is painful. STTBox literally changed how I work — I can draft emails, write reports, even code comments with my voice. The privacy guarantee was what convinced me to try it."

★★★★★
"ChatGPT + STTBox is a productivity superpower. I think out loud, it types, GPT responds. My idea-to-output speed tripled. I've tried every voice extension — this one has the best React/SPA compatibility."

First, make sure the Chrome microphone permission is granted for that site. STTBox works on almost all sites, but a few (like bank dashboards) use strict Content Security Policies that block extensions. If you find a site that doesn't work, report it and we'll investigate.
