Prism by brian

You're three tabs deep into a debugging session. You've got the error, the relevant function, an API response, and some docs open. You switch to Claude and spend the next five minutes copy-pasting everything in manually. Again.
PRISM fixes that.
It's a Firefox sidebar where you build up your AI context while you work — right-click anything to add it to the tray, capture whole pages in one click, set a session goal, organise by group and label. When you're ready, Generate assembles everything into a perfectly structured prompt. One more click fires it at Claude, ChatGPT or Gemini.
Smart type detection adds proper code fences automatically. A live token meter keeps you under budget. Sensitive data gets flagged before you accidentally share an API key. Aging indicators tell you when a snippet is going stale.
