How our tools work
- In your browser. The work happens on your device, so nothing you paste, record or upload is sent to our servers.
- Free, without catches. No account, no email gate, no watermark and no artificial limits.
- Clear about what changes. Each tool shows exactly what it found and changed, and explains its results in plain language.
- Fast on any device. Pages load quickly on phones and laptops, and the tools keep working if your connection drops.
