Questions people ask

Are these tools really free?

Yes. There is no signup and no paywall. AI drafting uses your own free key from a provider such as Groq or Google, so you are never billed by us.

Why “learn by doing” instead of one-click generation?

One-click output teaches nothing and is often wrong. Each tool makes you brief, check and improve — the skills that transfer to any AI tool.

Do I need an AI key to use this?

No. The guided template teaches the same skill with no AI at all. If you add your own free key (Groq, Google Gemini, OpenRouter, Mistral or Cerebras), the tool can also draft and revise. The key stays in your browser and requests go straight to that provider.

Where is my work saved?

In this browser only (local storage), until you copy or download it. Nothing you type is sent to Open Practice.
