Upload a clip, mark where the extension should begin on the waveform, and the AI writes what comes next in the same style. Add lyrics or keep it instrumental.
No parameters are preset on this page. Upload a clip, check the marker on the waveform, and press generate; add lyrics and a style for more control.
Songs written in a rush often stop before they feel finished: a verse and a chorus, a loop that begins to groove, a theme that needs a bridge. An extender listens to what you have and writes the next section in the same key, tempo and sound, so you are not starting a second song from scratch.
The page works from the clip you upload and the point you mark. That point is the handover: everything before it is context, and everything after it is generated.
The marker is placed close to the end of your clip by default, which is right for continuing a track forward. If the last second ends on a tail or a fade, drag the marker back to the last clear musical phrase. A join on a downbeat or the end of a bar sounds more natural than one placed mid-chord.
You can also place the marker in the middle of a clip to replace the ending with something new. Run it from a few different points and compare the results; each costs 9 credits.
Without any input, the model infers the style from the audio. If you want to steer it, switch on custom settings and give the extension its own lyrics, a style description and a title. Reusing the style tags from the original generation keeps the continuation consistent.
For a bridge or an outro, ask for it in the prompt. Describing the role of the section, such as a stripped back bridge with a rising piano, tells the model what job the new music has to do.
The extension is generated music, so the join may not be seamless and the continuation can drift in energy over longer outputs. Because the uploader trims clips to 60 seconds, an extension is best treated as a way to grow an idea section by section instead of rebuilding a long song in one step. Keep the original files, and crossfade the extension in an editor if the joining point is audible.

Typical jobs for a longer track.
Turn a 30 second loop into a section long enough to build on.
Stretch a short cue to cover a longer scene, then fade it in your editor.
Place the marker at the final phrase and ask for a closing section.
Run several continuations from the same point and pick your favourite.
Upload, choose the join point, generate.
Add one audio file. Longer files open the trimmer so you can pick up to 60 seconds to send.
Trim to the best section first
The marker starts near the end of the clip. Drag it on the waveform to continue from earlier in the track.
End on a musical phrase, not mid-note
Optionally switch on custom settings for lyrics, style and title, or toggle instrumental. One run costs 9 credits.
Reuse the original style tags so the continuation matches
