GreedySearch for Pi
Multi-engine AI web search for Pi via browser automation.
- No API keys
- Real browser results (Perplexity, Bing Copilot, Google AI)
- Optional Gemini synthesis with source grounding
- Chrome runs headless by default — no window, purely background
Install
pi install npm:@apmantza/greedysearch-pi
Or from git:
pi install git:github.com/apmantza/GreedySearch-pi
Tools
greedy_search — multi-engine AI web searchwebsearch — lightweight DuckDuckGo/Brave search (via pi-webaio)webfetch / webpull — page fetching and site crawling (via pi-webaio)
Quick usage
greedy_search({ query: "React 19 changes" });
greedy_search({ query: "Prisma vs Drizzle", engine: "all", depth: "fast" });
greedy_search({
query: "Best auth architecture 2026",
engine: "all",
depth: "deep",
});
// Headless is the default — no window. To force visible Chrome:
greedy_search({ query: "Bing captcha setup", engine: "bing", visible: true });
Parameters (greedy_search)
query (required)engine: all (default), perplexity, bing, google, geminidepth: standard (default), fast, deepfullAnswer: return full single-engine output instead of previewheadless: set to false to show Chrome window (default: true)visible / alwaysVisible: set to true to always use visible Chrome for this search
Environment variables
| Variable | Default | Description |
|---|
GREEDY_SEARCH_VISIBLE | (unset) | Set to 1 to show Chrome window instead of headless |
GREEDY_SEARCH_ALWAYS_VISIBLE | (unset) | Set to 1 to force visible Chrome for all GreedySearch runs |
GREEDY_SEARCH_IDLE_TIMEOUT_MINUTES | 5 | Minutes of inactivity before auto-killing GreedySearch Chrome |
GREEDY_SEARCH_LOCALE | en | Default result language (en, de, fr, es, ja, etc.) |
CHROME_PATH | auto-detected | Path to Chrome/Chromium executable |
Depth modes
fast - quickest, no synthesis/source fetchingstandard - balanced default for engine: "all" (synthesis + fetched sources)deep - strongest grounding and confidence metadata
Runtime commands
Inside Pi, prefer the extension commands (no package path needed):
/greedy-visible # launch visible Chrome for captcha/login/cookie setup
/greedy-status # show GreedySearch Chrome status
/greedy-kill # stop GreedySearch Chrome
/set-greedy-locale # set default result language (de, fr, es, ja, etc.)
Git install path:
GS=~/.pi/agent/git/github.com/apmantza/GreedySearch-pi
node "$GS/bin/launch.mjs" --status
node "$GS/bin/visible.mjs" # visible mode
node "$GS/bin/visible.mjs" --kill # strong visible/port cleanup
node "$GS/bin/kill-visible.mjs" # same as visible.mjs --kill
node "$GS/bin/cdp-visible.mjs" list # safe CDP: GreedySearch visible Chrome only
node "$GS/bin/cdp-headless.mjs" list # safe CDP: GreedySearch headless Chrome only
node "$GS/bin/cdp-greedy.mjs" list # safe CDP: any GreedySearch Chrome mode
npm global install path:
GS="$(npm root -g)/@apmantza/greedysearch-pi"
node "$GS/bin/launch.mjs" --status
node "$GS/bin/visible.mjs"
node "$GS/bin/visible.mjs" --kill
node "$GS/bin/kill-visible.mjs"
node "$GS/bin/cdp-visible.mjs" list
node "$GS/bin/cdp-headless.mjs" list
node "$GS/bin/cdp-greedy.mjs" list
Chrome is auto-cleaned after 5 min idle. Override with GREEDY_SEARCH_IDLE_TIMEOUT_MINUTES=10 or disable with 0.
CDP safety: use cdp-visible.mjs, cdp-headless.mjs, or cdp-greedy.mjs for debugging. They always set CDP_PROFILE_DIR to the dedicated GreedySearch Chrome profile and never fall back to your main Chrome session. Avoid calling raw bin/cdp.mjs manually unless you explicitly set CDP_PROFILE_DIR.
Requirements
Known engine quirks
Bing Copilot
Bing Copilot detects headless Chrome and sandboxes all AI responses inside nested iframes (copilot.microsoft.com → copilot.fun → blob:). In this mode the copy button is hidden and the Cloudflare Turnstile challenge blocks content delivery. The clipboard-based extraction cannot work.
Auto-recovery: When Bing or Perplexity fails with a headless-only extraction error (clipboard, verification, timeout, Cloudflare), GreedySearch automatically switches to visible Chrome and retries, even in fast mode. If manual verification is required, the visible browser is left open and the tool returns instructions to solve the challenge and rerun the same search.
