LetterMint AI is a complete AI-powered content creation and productivity suite that runs full Large Language Models entirely inside the user’s browser. No backend servers, no API keys, no monthly subscription fees. Powered by WebLLM and WebGPU hardware acceleration, it delivers real AI inference using models like Llama 3.2, Phi 3.5, and Gemma 2 on hardware users already own.
This is not a wrapper around a cloud API. This is not a UI mockup with fake responses. LetterMint AI downloads real LLM weights into the browser cache and runs genuine on-device inference with streaming output. Completely offline-capable once models are cached.
