Unique

In-page quality monitor for Claude, ChatGPT, Gemini, and Perplexity so you see when a thread is worn out.

Problem

Long chats on Claude, ChatGPT, Gemini, or Perplexity quietly get worse. People keep going until answers feel vague, then blame the model instead of the thread.

What it is

A Chrome extension that watches those chats and scores how tired the conversation feels:

  • Token fill, re-asking, and heuristic signals
  • On-page pill, popup ring, and badge so you can see quality while you work
  • Works on Claude, ChatGPT, Gemini, and Perplexity

Approach

Read the open chat in the page, score it locally in the extension, and surface a simple status so you can decide when to start fresh.

Outcome

You can tell when a thread is worn out and start a new chat before the answers fall apart.
