Frequently asked questions
What is BYOK?
BYOK (Bring Your Own Key) means you use your own API key from Google, OpenAI, or Anthropic. Your key is stored locally in your browser and sent directly to the provider. We never see or store it.
What does Pro include?
Pro gives you access to Claude, GPT, and Gemini without needing your own API key. We handle the API costs — you just use the tools. It also includes unlimited AI chat, tool history, and an ad-free experience.
Can I use the tools without AI?
Absolutely. All 25+ developer tools work perfectly without AI or any API key. AI features are optional enhancements.
Is my data safe?
Yes. All tools run entirely in your browser. Your data never leaves your device. When using AI features, data is sent only to the AI provider you choose.
