Everything ThreadCast does

A complete breakdown, by category.

Narration

  • Multi-voice author assignment

    Each unique username is hashed to a voice from your device's Web Speech library. The same username always gets the same voice, across every thread.

  • Gender-aware matching

    Voices are grouped by presentation, so usernames tend toward matching voice characteristics. Makes long threads with many authors far easier to follow.

  • Post & comments

    The main post body is read first, then comments in thread order. Nested replies are indented in tone and attribution.

  • Adjustable speed

    Set playback speed per session. Slower for dense technical threads, faster for casual browsing.

Queue

  • Multi-thread queue

    Open multiple threads into the queue without navigating away. Each queues up as a separate episode.

  • Drag to reorder

    Rearrange your queue freely. Change your mind after building it.

  • Auto-advance

    When one thread finishes, the next starts automatically. Keep listening without touching your device.

  • Import / export settings

    Back up your voice preferences and queue config. Move between devices or restore after reinstall.

Sleep mode

  • 10 ambient tracks

    Hand-picked ambient audio: Burning Mist, Drifting, Evening Prayer, Mullan Sun, Paths We Left Behind, Reflections Of Light, Renew Tranquilium, Reverie, Shoreline, Transcend.

  • Fade-to-silence timer

    Set a timer. Audio gradually fades over the final minutes, so you drift off without a jarring stop.

  • Screen-off compatible

    Playback continues when you lock your screen. Works on both the Android app and Chrome with screen-off extensions.

Privacy & performance

  • Zero network calls for audio

    All speech synthesis uses the Web Speech API, which runs locally on your device. No audio data is ever sent anywhere.

  • No account required

    Install and use immediately. We never ask for an email, Google account, or Reddit login.

  • No analytics on content

    We collect no data about what you read. The extension operates entirely on-device.

  • Minimal permissions

    The extension only requests access to reddit.com. No broad host permissions, no history access.
