Your private AI homework helper—bring your own API key, zero data leaves your device
Students risk their personal homework data being exposed through cloud storage in popular AI learning apps lacking privacy protections.
PrivyTutor provides a specialized browser-based interface for homework help using student-supplied LLM API keys (OpenAI, Anthropic, etc.), with all API calls made directly from the browser. Homework chats stay ephemeral or local-only unless exported, ensuring no data ever reaches our servers. Parents love the transparency of BYO keys for full control over data privacy.
