LLM Context Harvester

Export full Claude, Gemini and Meta AI chats (reasoning, artifacts, code) to Markdown + JSON.

Copy-pasting an AI chat loses half of it: the reasoning, the artifacts, the code formatting, the math. LLM Context Harvester exports the conversation open in your tab, in one click, from Claude, Gemini and Meta AI: • every message, in order (full history, even on long chats) • reasoning: Claude thinking, Gemini thoughts, Meta AI reasoning steps and sources, web searches • Claude artifacts (final version) and Gemini Canvas source code • code blocks with language, math (LaTeX), tables, SVG / Mermaid diagrams You get two files in Downloads: a clean Markdown file ready for an LLM agent, and a unified JSON file. You can also copy the Markdown to the clipboard. Everything runs locally in your browser. Nothing is collected or sent anywhere. Not affiliated with Anthropic, Google or Meta.
