Enable Auto-Narration

Automatically converts textual slides into Audio Narrations! Automatically calibrates Slide Time mappings.

TTS Engine & Voice

Default loads on every page open. Switch any time — the dropdown picks up the new default.

Chatterbox Model

Turbo supports inline [laugh]/[sigh]/etc. tags. Multilingual unlocks Japanese (and 22 more) — pick the language to the right.

Chatterbox Expression Tags

Heads up: tags work only on Turbo (Base will speak them as letters). Clicking a tag here copies it to clipboard AND auto-switches the model to Turbo. No wrap tags exist for Chatterbox — style is controlled via API sliders.

Countdown Overlay (Q slides)

Overlays countdown numbers on the last 5 seconds of each Question slide.
