Use the AI song extender to continue a song you made with Nano AI Song. Choose a track from your library, set the point where the music should continue, and give the next section a direction. Your original song stays in your library.
Sign in to open your library and look for Extend on a finished track. Eligible tracks were created within the last 14 days and have compatible song information. Each extension costs 1 Nano AI Song credit. Opening the library or editing your instructions does not start a generation.
Choose a song from your libraryOpen a completed generation in your library and listen to the version you want to continue. Select Extend beside that track. If a generation has more than one result, make sure you choose the right recording: the same lyrics can lead to different melodies and arrangements.
Enter a position in seconds that is after the start and before the end of the recording. For example, 75 means one minute and fifteen seconds. Listen around that moment before submitting. A pause after a vocal line or the end of a musical phrase can be a useful place to try.
Give the result a title and, if you want, add a style direction. For a song with vocals, you can also supply lyrics for the new section. Review your choices, then submit the extension. When it finishes, the new result appears as a separate generation in your library.
Before you extend music, decide what the extra section needs to do. Perhaps a verse stops before the story is finished, or the ending arrives too quickly after the chorus. A specific aim makes it easier to judge the result. You might ask for a quieter ending with piano, or a new verse that keeps the drums steady. Keep the direction close to the recording if you want continuity. A large change in genre or energy may sound like a different song, and a continuation is not guaranteed to reproduce every detail of the original performance.
The continuation position tells the AI song extender where to pick up the music. It does not set a target length for the finished result. Listen to a few seconds on either side of your chosen point, especially if someone is singing. Cutting through the middle of a word can make the transition harder to judge. Write down the position you tried so you can compare it with another attempt. If the result feels abrupt, consider a nearby phrase boundary and a simpler instruction before spending another credit. The length and musical transition of each generated result can vary.
For vocal tracks, the optional lyrics field is a place to write the words you want in the continuation. Read the previous line first. If the original verse ends with a question, the next lines might answer it; if the chorus has just finished, a short new verse may give the song somewhere to go. Try lines with a similar length and rhythm to the section you liked. You can use section labels such as [Verse] or [Outro] to suggest structure, but the performance may interpret them differently. Use words you have the right to provide. You do not need to paste the full original song merely to add a few new lines.
Each extension is a new generation, so you can return to the original recording while judging the new one. A descriptive title helps: try a name such as Late train, quiet ending rather than giving every attempt the same name. Listen for whether the new section develops the melody, whether the words are understandable, and whether the transition works for your intended use. An AI song extender can give you another direction to explore; it cannot promise a particular vocal delivery or a perfect edit. Save a download of a result you want to keep and listen to the full recording before using it in a video or sharing it.
You can extend eligible songs generated in your own Nano AI Song account within the last 14 days. The generation must be finished and contain compatible information for the selected track. Your library shows Extend when a track is eligible. Older tracks, unfinished generations, or recordings without the required information are unavailable for extension even if you can still listen to them.
This tool starts from a track in your Nano AI Song library. It does not accept uploaded audio, external song links, or another person's library tracks. If you have only a written idea or your own lyrics, start a new song in the studio first. After generation finishes, check the library for the Extend action.
No. The original generation remains in your library, and the extension has its own result. Choosing a continuation position does not edit or delete the original audio. Keep both versions while you compare the result. You can return to the source recording if the new section does not fit what you had in mind.
An extension uses 1 Nano AI Song credit when you submit it. You need to sign in and have enough available credits. If the generation fails, the credit is returned automatically. While a request is still processing, wait for its status or use the recovery option shown in the library instead of starting another request for the same attempt.
The continuation point selects where to continue, not how many seconds to add. There is no exact output duration control. For an instrumental source, you can describe the musical direction, but a result without vocals is not guaranteed. Listen to the generated audio before deciding whether it fits your project, especially when you need background music without singing.
