Capabilities

Tools 12

begin_local_export

Widget only: reserve a free 720p export to render in the browser.

Discovered
choose_style

Applies one of the three proposed style options (1, 2 or 3) to the lyric video. Replaces any edits made to the current style.

Discovered
create_lyric_video

Turns a song the user attached (MP3/WAV) into a word-synced lyric video and proposes three visual styles. Pass the lyrics if the user gave them; otherwise they are transcribed from the audio. Takes about 10–40 seconds. Creates a new project each call.

Discovered
edit_lyrics

Replaces the text of one lyric line (numbered from 1, as listed by get_lyric_video), keeping its timing. Use it to fix misheard or misspelled words.

Discovered
export_hd_video

Renders the lyric video in 1080p without a watermark, as 16:9 (landscape) or 9:16 (vertical). Requires the user's LyricVideoGenerator account: it uses 1 credit from their plan (or is free if this song was already unlocked on the website). Credits are refunded if the render fails. Returns an exportId; the widget shows progress and the download link.

Discovered
export_video

Free export: a 720p, 16:9 MP4 with a small watermark and a 2.5-second end card. It renders on the user's own computer inside the widget (about as long as the song), so this tool shows the widget and starts the export there; the user downloads the MP4 from the widget when it finishes. If their ChatGPT app can't render video, the widget offers to open the project in their browser instead.

Discovered
finish_local_export

Widget only: complete a browser-rendered export after its upload, or fail it with an error.

Discovered
get_export

Returns the status of a video export and, when finished, its MP4 download URL.

Discovered
get_lyric_video

Returns a lyric video project's processing status, its three style options, the style now applied, and its numbered lyric lines.

Discovered
open_in_browser

Widget only: a short-lived link that opens this project in the user's browser, where it can be exported.

Discovered
update_style

Changes the look of the current lyric video style: layout, word animation, colors, font, text size, background, and chorus emphasis. Send only the fields to change. Colors are #RRGGBB. Unreadable color combinations and unknown fonts are corrected or rejected with a reason.

Discovered
upload_local_export

Widget only: storage upload target for a browser-rendered MP4.
