Prompt pieces, like Lego. You build the video.

AI Prompt Builder is a library of small, single-feature prompt pieces — a lighting piece, a camera-move piece, a grade piece. Pick the pieces you need, add them to your main prompt, and get exactly that feature. We make the tested pieces; what you build with them is your call.

Honest status, up front

All 38 pieces below are written and complete as drafts — none of them is labelled “Tested” yet, because a piece only earns that label after a real run on a real tool, with the proof recorded. 26 pieces are in the launch batch (waves T1–T3) and are being tested first; the rest are listed as coming soon, never as finished listings.

How the launch batch works

Testing runs in waves. T1 — six code-route pieces (speed ramp, easing, beat cuts, morph, kinetic type, logo reveal) tested in-house first. T2 — twelve hero generator-side pieces (push-in, orbit, golden hour, the Consistency Lock, product turntable, UGC testimonial…) tested on real generations. T3 — eight pieces proven inside the T2 stacks they naturally ride in. Pieces that pass ship as Tested; what broke gets recorded on the piece page, not hidden.
