How Zahvox works in Japan
Chrome and Safari cover the majority of Japanese traffic on both desktop and mobile, both of which support the Web Speech API. To start, open /tool in a supported browser and grant microphone permission once. Live transcription shows your words appearing as you speak, with a small delay while the browser processes each phrase. You can pause, resume, and edit inline — Zahvox is a writing surface, not a passive recorder.
The mic icon stays visible so you always know when the tool is listening. Your audio never touches a Zahvox server: the browser sends short audio snippets to its own speech engine (usually Google for Chrome and Edge, Apple for Safari) and returns text. When you close the tab, nothing is stored. You can copy the final text with one click or download it as a plain text file.

On the roadmap for Japan: Japanese. To try a different language today, switch your browser or system language and the underlying Web Speech engine will use its matching model where available.

Zahvox vs. voice-to-text alternatives available in Japan
Japan users have three main options for turning voice into writing today. None of them are wrong — they just solve different problems. Here is an honest comparison so you pick the right tool for the job.
| Tool | Best for | Cost | Signup |
|---|---|---|---|
| Zahvox | Solo writing — emails, notes, drafts | Free core tool | Not required |
| Built-in OS dictation | Typing into any app quickly | Free with your OS | System account |
| Browser-based free tools | Similar solo writing use | Free | Varies |
| Paid meeting transcription | Multi-speaker meeting notes | Subscription | Account required |
Zahvox's honest edge is the writing surface — a clean workspace built for editing what you just said, with zero signup and zero install. For multi-speaker meeting notes, use a dedicated meeting tool. See a longer breakdown on the alternatives and compare pages.
FAQ — Voice-to-text in Japan
Does Zahvox work in Japan?
Yes. Zahvox is fully available across Japan. The free web tool works in Chrome, Edge, and Safari on any Japanese network, with no signup and no local install required.
Can I dictate in Japanese with Zahvox?
You can dictate in Japanese today by setting your browser and system language to Japanese. Chrome, Edge, and Safari use a Japanese speech engine in that case. First-class Japanese support is on Zahvox's roadmap.
Is Zahvox APPI compliant in Japan?
Zahvox's free tool never uploads or stores your audio on our servers, so most controller obligations under the APPI do not apply for personal use. Businesses handling client voice should still confirm their own PPC-related duties.
Is voice-to-text accurate?
Yes, for clear speech at a normal pace. Zahvox uses your browser's built-in speech engine, which reaches 90%+ accuracy for common accents in quiet rooms. Accuracy drops in loud rooms, with heavy code-switching, or with rare technical terms.
Does voice-to-text work offline?
No. Zahvox's free web tool relies on your browser's Web Speech API, which sends audio to the browser vendor's speech servers. An offline mode is not part of the free browser tool. Native offline dictation is on the roadmap for future clients.
Is my voice data private when using an online voice-to-text tool?
Zahvox never uploads or stores your audio on a Zahvox server. Your browser handles the mic and sends short audio snippets to its own speech engine (usually Google for Chrome and Edge, Apple for Safari), which returns text. No account and no recording are created.
What is the difference between voice-to-text and dictation?
Dictation is a broad term for speaking your writing. Voice-to-text is the technology that converts speech into written characters. Zahvox is a voice-to-text web tool built for writing — not for transcribing meetings with multiple speakers.
Do I need to install anything to use Zahvox?
No. Zahvox runs entirely in your browser. Open the tool page, grant microphone access once, and start speaking. There is nothing to install, no signup, and no download for the current free experience.
Which browsers support voice typing?
Chrome, Edge, and Safari support the Web Speech API that Zahvox uses. Firefox has limited support. On mobile, Chrome on Android and Safari on iOS both work. You need microphone permission granted once for the page.
Can I add punctuation by voice?
Yes. Say the punctuation word — for example, 'comma', 'period', 'question mark', or 'new line'. Different browsers handle punctuation commands slightly differently, so a quick edit pass at the end is normal for polished writing.
Is Zahvox really free?
Yes. The current web tool is free with no signup, no time limits, and no credit card. Future advanced features (AI cleanup, saved history, templates) will be part of paid tiers, but the core voice-to-text tool stays free to use.
How is Zahvox different from Google Voice Typing or Apple Dictation?
Built-in OS dictation is a system feature that types into any app. Zahvox is a dedicated writing surface with editing tools, one-click copy, and download — plus a clean workspace for polishing the draft, not just capturing it.
How is Zahvox different from Speechnotes or Otter.ai?
Speechnotes is the closest browser-based free alternative. Otter.ai is a paid meeting transcription tool with speaker labels and account storage. Zahvox is a free, no-signup writing surface — best for solo writing, not multi-speaker meetings.
Can I export or download the transcribed text?
Yes. You can copy the text with one click or download it as a plain text file directly from the tool. Nothing is stored on Zahvox's servers, so the copy or download is your only record of the session.
Does Zahvox work for meetings with multiple speakers?
No. Zahvox is built for one voice — your writing. For multi-speaker meeting transcription with speaker labels, use a dedicated meeting tool. Zahvox is faster than those tools when the goal is your own draft.
Who built Zahvox, and how your voice is handled
Zahvox is built by Hussain Jatoi and launched by Hussainjatoi.com. The company is small on purpose — a real founder shipping a real tool. Read the about page for the full story and the roadmap for what is next.
Honest privacy note
Zahvox's free web tool uses the browser's Web Speech API. That means short audio snippets are sent from your browser to your browser vendor's speech servers (Google for Chrome and Edge, Apple for Safari) so it can return text. Zahvox itself never receives, stores, or replays your audio. No account is created for using the tool, and closing the tab removes the transcript. This is different from claiming "100% offline" — we would not tell you that when the browser engine is doing the recognition work.
Japan's Act on the Protection of Personal Information (APPI), overseen by the PPC, treats voice recordings as personal data when they identify someone. Zahvox's free tool never uploads or stores audio on our servers, which keeps personal use simple.
