HOW IT WORKS:

Moka is free. The artificial intelligence runs with YOUR API key (BYOK) — you choose the provider (DeepSeek, OpenAI, Z.ai, Grok, Groq, and more). The keys are encrypted on your device.

Use an affordable AI like DeepSeek and pay only cents per book. With OpenAI, you also get neural voice and video transcription.
