Summarize Anything · swyxio bundle
Summarizes arbitrarily long text (1k-1M words) using recursive map-reduce with any LLM backend. Accepts raw text, markdown, transcripts, articles, codebases, or any plaintext input.

Pluggable backends: OpenRouter, Ollama, OpenAI, Anthropic, Gemini, or any OpenAI-compatible endpoint. Use this skill when someone says "summarize this", "give me a summary", "TL;DR", "make this shorter", "create a YouTube description", "write a tweet about this", "generate titles", "thumbnail ideas", or provides long text and wants any condensed output.

Exclude ordinary fast requests and backend-only changes with no user-facing operation affected.
