What Flint does

Flint is a Chrome extension that reads the text you type in Claude.ai and sends it to our server to analyze and score it, helping you write better prompts.

What data we collect

• Prompt text: The text you type into Claude.ai is sent to our backend for analysis. We do not store this text after returning the result — it is processed and discarded immediately.
• No personal data: We do not collect your name, email, IP address, or any identifying information.
• No browsing history: Flint only activates on claude.ai. We do not read any other tabs or websites.

What we don't do

• We do not sell your data
• We do not store your prompts
• We do not share anything with third parties
• We do not require an account or login

Third-party services

Flint uses Groq (groq.com) to process prompt analysis. Prompts are sent to Groq's API and are subject to Groq's privacy policy. Groq does not retain prompt data for training purposes.

Local storage

Flint stores your usage statistics (number of prompts analyzed, scores) locally in Chrome storage on your device. This data never leaves your browser.
