// The problem

You're flying blind
on your Claude plan.

r/ClaudeCode

"4 hours of usage gone in 3 prompts. Used plan mode to refactor a frontend. Worst part is I just re-subscribed."

r/ClaudeAI

"There's no way to know how much of your limit you've used until you suddenly hit it mid-conversation."

r/AI_Agents

"I had no idea my agent was burning through my plan that fast. By the time I checked I had used 80% in a single session."

How people describe it: "flying blind" "hit the limit mid-conversation" "no way to know" "burned through"
