Everything runs in this tab. Nothing is uploaded — no server, no analytics; Rendre hands renders over browser to browser. Nothing is kept unless you download it.

Video export uses mp4-muxer (Vanilagy, MIT License). Cull & rank and Tinct's blind test share the Glicko rating system (Mark Glickman, 1995). Built by Phil Renato and Claude (Anthropic) as a companion to Rendre, Phil's research renderer — part of renato.design.
