FAQ
Common questions
Which AI platforms does Flint support?
Flint works on ChatGPT, Claude, Gemini, Perplexity, Grok, Microsoft Copilot, DeepSeek, and Poe — with more platforms added regularly.
Does Flint read my conversations?
Flint only reads the text in the prompt box you're actively typing in. We never access your conversation history or AI responses.
How is my data stored?
Your prompt history is stored securely and is only accessible by you. You can delete your data at any time from the dashboard.
Is there a free plan?
Yes — the free plan gives you 30 prompt scores per month with full access to one-click rewrites. Pro unlocks unlimited scoring and advanced analytics.
How is Flint different from just asking the AI to improve my prompt?
Flint scores before you send — so you fix the prompt before the AI ever sees it. It also learns your personal style over time, something a fresh AI chat can't do.
