Local-first · Private

Private lyric video maker — your audio never leaves your device

Threnic is built local-first: your unreleased track, your lyrics, and your artwork stay on your own computer. Rendering happens on your GPU, in your browser. Nothing is uploaded, streamed, or stored on our servers — so you can make a lyric video for a song no one has heard yet without it ever touching the cloud.

Why local-first matters for musicians

Most online lyric video makers upload your audio to their servers to render it. For an unreleased demo, a leaked-sensitive master, or a client's track under NDA, that is a real risk — your file now lives on infrastructure you don't control. Threnic takes the opposite approach: the audio you load is read directly by the browser and processed by your local GPU. It is never transmitted anywhere.

This is genuinely hard for cloud-based competitors to match. Their whole architecture depends on server-side rendering. Threnic's render pipeline runs client-side, which is exactly why your files can stay private.

What stays on your device

  • Your audio file (MP3/WAV) — read locally, never uploaded
  • Your lyrics, whether typed, pasted, or imported from LRC
  • Background images and artwork you add
  • The entire render and 4K export — encoded on your own GPU
  • Saved projects — stored in your browser, not our database

Private and still fully featured

Local-first doesn't mean stripped down. You get the full audio-reactive effect suite, real-time preview, precise lyric timing, and export up to 4K without a watermark. Privacy is the default, not a mode you have to switch on.

Frequently asked questions

Is my music uploaded to Threnic's servers?

No. Threnic uses a local-first architecture. Your audio, lyrics, and images stay on your device, and rendering happens in your browser using your own GPU. Nothing is uploaded, transmitted, or stored externally.

Can I make a video for an unreleased song safely?

Yes — that is exactly what local-first is for. Since your file never leaves your computer, you can build a lyric video for a demo or unreleased master without it touching the cloud.

Where are my projects saved?

Locally in your browser. You can also export a .thren project file for backup or to move between computers.

Does anything get sent to the server at all?

Your creative assets do not. Threnic has no accounts or billing; the only thing sent is anonymous, cookieless usage analytics, which never include your audio or video content.
