How it works
One line, from the script to the film.
Five chapters follow one line of Halfway, the fictional 38-second pitch the front page plays a 35-second cut of, from the script to the film: "Twenty minutes for her. Twenty minutes for you." The pinned stage replays the cut as you read.
1 of 5
You write the script.
2 of 5
Your voice reads it, with a time for every word.
3 of 5
A cue names the word or phrase each picture waits for.
4 of 5
The slide is plain HTML, and each picture carries its cue.
5 of 5
A browser films the slide, and every landing is measured.
Underlined phrases are cues. The small number is how many seconds into this section the picture appears. Click a word to move the stage there. Tab in, use the arrow keys, and press Enter to play from a word.
The stage replays the 0:35 cut the front page plays, from its slides and its recorded voice. The full 0:38 film is on its own page.
Change one number
One number lives in three files. Only its section was voiced and recorded again.
Section 3 of Halfway, the pitch this page takes apart. Press both: the same cloned voice, before the edit and after it.
Last month, eleven thousand people met in the middle. Coffee. Lunch. One first date that became a second.

Every landing is measured against its word.
Make one
One line to install.
curl -LsSf https://decktalk.ai/install.sh | shIt installs uv, then DeckTalk, and never runs sudo. Two more lines make a first film, with placeholder narration and no key.
Next: the full 0:38 film and its script, uv, end to end, a 3:16 tutorial made the same way, or the quickstart.
