Most reads fail for two reasons: the text is too small to catch at a glance, and the scroll is faster than your natural speaking pace. Push the font size up until you can read a full line without moving your eyes, then lower the speed until you stop rushing. Write in short sentences — a script written for the ear scrolls far better than one written for the page.
Zahvox is built for people who speak faster than they type. The fastest way to a natural-sounding script is to speak it first in the free voice-to-text tool, tidy the transcript, then read it back here at your own pace.
Zahvox starts with free tools, but the larger platform is being built for voice-to-writing workflows across notes, emails, replies, drafts, and future extension experiences.
Current web experience available today. Browser extension, AI cleanup, personas, writing modes, saved history, and desktop app are in development or planned.
This free tool supports the Zahvox voice-to-writing workflow. Use the main voice tool to capture rough thoughts, then use this utility to clean, measure, format, or prepare the text before copying it into your workflow.
Zahvox starts with the reality that many people can explain ideas faster than they can type them.
The output should be easy to review, edit, copy, download, and reuse in the tools you already use.
Extension, cleanup, writing modes, personas, desktop, and saved history are planned as the platform grows.
