Browser Companion
What Growthract Companion does
A browser extension that captures a real response from your own ChatGPT, Claude, Gemini, Perplexity, or Copilot session.
Short answer
Growthract Companion is a browser extension that captures the actual response from your own logged-in ChatGPT, Claude, Gemini, Perplexity, or Copilot session — a real, point-in-time observation, not a simulated score.
What this means
Nothing is sent anywhere at capture time. You review the captured response, then choose to send it to Growthract yourself. The extension only reads the page content on a supported AI provider's site — it doesn't read cookies, tokens, or any other site.
What to do
Open the Companion popup on a supported provider's page, insert or ask your prompt, capture the response, then send it to Growthract to save it as an observation.
