Yes — 100% free, no signup, no watermark, no usage cap. Everything runs locally in your browser. Your script never leaves the page unless you enable the optional HD MP3 read-along, which sends text to our TTS server and gets back an audio file.

The pace selector and Timed mode use the same empirically-calibrated wpm/cpm tables as the Speech Time Calculator on this site — within ±3 % of real TTS playback. So if you pick "Conversational · 160", the script finishes in the time the calculator predicts.

When enabled, the script is spoken aloud while it scrolls — and the scroll is driven by the audio's playback position, not a timer. So if the voice slows down at a long sentence, the scroll slows too. Browser engine is instant; HD MP3 takes 2-10 s to generate but gives studio quality.

Web Speech Recognition listens through your mic and matches what you said against the next words in the script, then nudges the scroll position so the next un-read word stays on the marker line. Works best in quiet rooms with clear speech. Falls back to fixed-pace scroll if recognition isn't supported (Safari, Firefox).

Yes — flip "Horizontal mirror" for beam-splitter rigs (the text reads correctly when reflected off the glass). "Vertical mirror" handles upside-down hardware mounts. Combine both for ceiling-mounted glass.

No — the recording captures only your microphone. The TTS audio plays through your speakers/headphones but the mic only picks up your voice. Use headphones to prevent bleed.
