OpenCode AI renders nearly everything in Berkeley Mono and treats the page like a manpage or README. Cream paper surfaces, almost-black ink, and ASCII cues make the interface feel radically terminal-native and unusually disciplined.
OpenCode Manual sits inside the Product family and is best known for monospaced product clarity with terminal-manual discipline. Use it when you want interfaces that feel ai coding tool homepages while still shipping with a clear reusable spec.
