Lekh AI is a native application designed for iPhone, iPad, and Mac that operates powerful artificial intelligence models entirely on-device. Its main purpose is to provide users with comprehensive AI capabilities without requiring internet connectivity or cloud-based services, ensuring complete privacy and data security.

The app combines multiple AI functionalities including LLM chat, vision capabilities, PDF and document analysis, image generation, and voice interaction features. Users can chat with various AI models such as Gemma, Qwen, Llama, Phi, Mistral, and OpenELM, and engage in voice chat using Kokoro TTS technology.

Lekh AI operates entirely offline, running all AI processing locally on the user's device without any cloud APIs or external server dependencies. This unique approach eliminates data transmission to third-party servers and ensures that no user information leaves the device.

The primary benefit is complete privacy and data security since all processing happens locally. Use cases include private conversations with AI assistants, document analysis without uploading sensitive files, image generation without cloud dependencies, and voice interactions that remain entirely on-device.

The target users are individuals seeking private AI assistance on their Apple devices, particularly those concerned about data privacy and wanting to avoid subscription fees. The app requires no integrations with external services since everything runs natively on iOS, iPadOS, and macOS devices.
