Your viewers don't notice the cuts.
They feel the audio breaks.

Drag in your AI clips. Weft stitches them together and seals the audio seams — no heavy editor, no DAW, no hour in post.

Scene-aware, not stitched

Weft sees the frame — then fills the room.

Weft isn't crossfading two audio clips. It looks at what's on screen — the space, the textures, the action — and synthesizes the ambient sound that should be there. The cut doesn't get blended. It gets understood.

The invisible problem

A gap your ears
can't unhear.

Every clip carries its own sonic fingerprint. Cut between two, and the room tone drops. The brain registers it before the eye does.

30–120min
Per cut, manually
Hunting room tone, matching EQ, blending crossfades.

Of post-production time
Eaten by audio cleanup on a multi-clip montage.

How Weft works

Three steps. Zero touch.

Drop your timeline, click once. ~15 seconds per seam.

Step 01

Spectral fingerprint

Weft analyzes each clip's ambient signature — spectral centroid, noise floor, room tone.

librosa · Gemini Vision
Step 02

AI bridge synthesis

A 350ms ambient bridge that inherits both clips' sonic DNA — scene-aware, not a generic crossfade.

AudioGen · ElevenLabs
Step 03

One-click placement

The bridge drops onto a new A2 track, aligned to your cuts. Ready to render.
