Reader is your home for consumption - shelves, saved guides, continue reading.

After registration:

1. Read Welcome to Guides (first visit opens it automatically).
2. Open app.guides.co anytime for your library.
3. Save guides you find (heart icon) - build a personal corpus for yourself or for AI.
4. Connect AI as a reader - paste /g/{slug}/gdf URLs for quiz, summarize, or study flows (no API key if public + AI-readable).

Studio (create.guides.co) is for when you author:

1. New guide (/new) - manual or API import.
2. Notebooks - agent drafts on new accounts.
3. Connect an AI (/ai) - API key for notebook mode (Section 2).
4. Publish - visibility + AI-readable for reference URLs.

URLs for any guide {slug}:

• Reader: https://guides.co/g/{slug}
• GDF: https://guides.co/g/{slug}/gdf
• Plaintext baseline: ?format=plaintext
• RAG chunks: ?format=jsonl
