Prompt Enhancer is free forever with your own Claude API key

The pricing question always comes up, so let me be upfront: Prompt Enhancer is free forever if you bring your own Claude API key.

No subscription, no per-prompt markup, no account wall. Your key lives in your OS keychain, and your text goes straight to Anthropic — nothing routes through our servers. You pay Anthropic directly for what you actually use (usually fractions of a cent per prompt).

The idea was simple: a utility this small shouldn't ask for a monthly fee. You already pay for the model — we just make your prompts better before they get there.
