Multiple Groq keys & smoother recovery

Keep dubbing moving with ordered Groq API keys, clearer validation, and automatic rate-limit recovery.

Groq API keys

  • Add multiple Groq API keys and switch automatically when a key is rate-limited.
  • Test every configured key at once and see how many are working.
  • Duplicate keys and invalid key formats are rejected before saving.

Reliability

  • Rate-limit retries respect Groq's Retry-After delay when available.
  • Dev-mode FFmpeg resolution now falls back correctly to the bundled binary.
v1.1.0 Latest

Logo & watermark

Brand your exports with your own logo, and set a default so every new project picks it up automatically.

Logo & watermark

  • Burn a logo into the exported video, positioned in any corner or centered.
  • Adjustable size and opacity, previewed against your video before you render.
  • Set a default logo once in Settings — every new project starts with it applied.
v1.0.0

First public release

Dub any video or audio into another language with an AI voice and matching captions, on your own Windows PC.

Dubbing

  • 72 languages, with source and target chosen independently.
  • Around 400 Microsoft Edge neural voices — no API key, no account, free to use.
  • Word-level timing from Whisper, so captions and voice stay on the beat.
  • Lines are re-timed inside the voice engine rather than stretched afterwards, so pitch and tone stay intact.
  • Audio-only mode for podcasts and voiceovers.

Review before you commit

  • The whole translation is editable line by line before a single second of voice is generated.
  • Listen to any line in the project's voice, with your edits applied.
  • Preview any voice — it speaks a sample sentence in that voice's own language, so you hear the real accent.

Captions

  • Burned into the video, plus separate .srt and .vtt files.
  • 33 bundled fonts, including Nastaliq and Naskh for Urdu and Arabic.
  • Import your own fonts.
  • Per-word highlighting, three highlight styles, and a no-background option.
  • Right-to-left scripts render in correct reading order.

Setup

  • ffmpeg ships inside the app — nothing to install alongside it.
  • The installer adds WebView2 and the Visual C++ runtime only if your PC is missing them.
  • 3-day trial with 3 dubs a day, started from inside the app.

Known limitations

  • Windows only — there is no macOS or Linux build.
  • The installer is not code-signed yet, so Windows SmartScreen shows an unknown-publisher warning. Choose More info, then Run anyway.
  • Output video is capped at 1080p. Higher-resolution sources are downscaled, never upscaled.
  • Everything runs online — there is no offline dubbing mode.
