Kiln

AI is quietly flattening everyone's voice. The more I used Claude and ChatGPT to write faster, the less I sounded like myself. Kiln is a Mac app that fine-tunes a local LLM on your own writing in 20 minutes. You drop a folder, or connect Notion and Apple Notes through MCP. An Opus 4.7 orchestrator spawns sub-agents in parallel to clean your corpus. Three classifiers we distilled from 5,000 Opus labels run locally to judge quality, preference, and style. Once trained, your voice runs on Ollama. And the cool part: Kiln also exposes it as an MCP server. So you can plug it into Claude.app and Claude will write as you.
