Block Reddit, HN, and YouTube everywhere

The usual context-switch traps stay blocked on your whole machine. New browser profile? Incognito? Still blocked.

Start focus from Cursor or Claude

Native MCP. Ask your assistant to lock distractions before a refactor or debugging session. No separate focus app competing for attention.
