Upload a song.
We test it, we grow it.

RunSound generates videos from your track, posts them organically on TikTok and Instagram, and learns which one actually connects — before a single dollar of ad budget gets spent.

Upload a song or idea →
Free to test. You approve any ad spend before it happens.

Upload once. The agent handles the rest.

No dashboard to babysit — you get a status update, not a to-do list.

01 — Upload

Song or idea

A finished track, or a handful of rough hooks you haven't decided between yet.

02 — Generate

Videos, automatically

Lyric video, dance cut, visualizer — several variants made from your track.

03 — Test

Posted organically

Live on TikTok and Instagram. We read completion rate, saves, and shares.

04 — Boost

You approve, we spend

Real ad budget goes only behind whichever version actually worked.

Got 10 half-finished ideas and don't know which one to finish?

Upload the rough hooks — voice memos are fine, nothing needs to be mixed. RunSound turns each one into a short test video, posts them organically, and tells you which idea actually landed before you spend another hour finishing the wrong song.

Common questions.

Yes, once — we post to your own accounts, never anyone else's. You authorize it during signup, same as connecting any scheduling tool.
No. The agent proposes a winner and a budget once organic testing shows a clear signal — real ad spend only starts after you approve it.
Yes — that's the idea-testing flow. Upload a rough voice memo or hook, we generate a short test video and post it, and you get a ranked signal before you finish the song.
Idea testing and the organic test phase are free. If a video is worth boosting, you approve a specific daily ad budget before anything is spent — no subscription, no surprise charges.
