What makes it different
No manual video editing needed - guides are automatically converted to polished videos
Failed runs cost nothing, only finished video minutes are charged
Credentials never appear in videos - login happens in separate unrecorded browser
Native integration with coding agents via MCP server
Guides adapt to UI changes - buttons can move and labels can change without breaking
Made specifically for singing, not audio editing or professional production
