Developers — free API, no keySupport & FAQWhy ROK vs the big AIs
Most AI assistants lock their real tools — web search, file work, image generation — behind signups and paid plans. ROK's take is simpler: chat with files, code, and the web for free, no account to start, with your history staying on your device. Where the big three match that, the matrix below says so — and where they don't, it says that too.
