For cloud AI, yes: your own key from Google Gemini, Anthropic, OpenAI or OpenRouter (Gemini has a free tier). Or run a local model with Ollama or LM Studio and no key is needed.

KZRS itself is free (10 pages a day) or a one-time Supporter code per year. The AI is billed by your provider, not by KZRS. Only the bubble text is sent, so requests are small; the price depends on the provider and model you pick. Gemini's free tier and local models (Ollama, LM Studio) cost nothing.

No. Only the text inside the bubbles goes to the AI provider you choose. Detection, OCR, cleaning and typesetting run on your computer.

16: English, Indonesian, Javanese, Malay, Spanish, Portuguese, Japanese, Korean, Chinese (Simplified and Traditional), Thai, Vietnamese, Tagalog, Russian, Arabic and Hindi.

Yes. Remove the old device in Supporter activation, then activate the code on the new computer.

With a local model (Ollama, LM Studio) everything runs offline. A Supporter licence keeps working 30 days offline and renews itself when you are online.
