Export Claude Skill

Bundle the book as a Claude Skill folder (SKILL.md + JSONL knowledge base). "Download" sends a ZIP; "Install" writes directly to ~/.claude/skills/.

One-click book summary

Sends the book's text through an LLM and returns a structured summary. The API key from the Settings tab (browser localStorage) is sent along with each request.

Long books are split into batches of per-call budget chars, summarised separately, then merged. Lower the budget if you see "Single message too long" / "Input too long" upstream errors; raise it on long-context models to use fewer calls.

API keys

Saved in your browser's localStorage only — never written to the server's filesystem. Sent with each request that needs an LLM. A shell-exported env var on the server takes precedence if you also have one set there.
