Fanout – ChatGPT Query Analyzer por Sam Steiner

Fanout opens alongside ChatGPT and makes the hidden machinery of a conversation visible: every search query the model generated, every source it cited, which domains it trusted, and what named entities it identified — all organized by the prompt that triggered them.

WHAT IT SHOWS
• Search queries the AI generated (the "fanout") and any queries you typed
• Grouped and ranked citations from ChatGPT's web search
• Footnote sources and supporting links
• Named entities identified in the response
• Image search queries
• Domain frequency table across the whole conversation

FEATURES
• Side-by-side panel — stays open as you navigate between conversations
• Live search filter across all sections
• Show/hide individual data types
• Export as CSV, JSON, or Markdown
• History tab — last 20 analyzed conversations stored locally
• Citation quality indicators for missing or thin snippets

COMPLETELY PRIVATE
Fanout makes no network requests of its own. It reads your ChatGPT conversation using your existing browser session — the same data your browser already has — and displays it locally. Nothing is sent to any server. No analytics, no tracking, no account required. All history stays in your browser's local storage and never leaves your machine. The full source code is on GitHub.

Requires an active ChatGPT account and a conversation that used web search.
