The Artifice Girl.
Movie from 2023 that seems to have slipped under the radar.
It’s about a man who develops an AI to target online predators played out through 3 short 30 minute acts.
I don’t know where they found the lead child actress but she blew me away. Movie absolutely floored me with how good it was.
Glad you enjoyed it. It really just came out of nowhere for me. I found it on some YouTube list iirc
