WebInfo: Watch an AI Agent Find the Answer for You

WebInfo is an AI agent that does web research for you. Ask a question in plain English and it searches the web, opens the real websites in its own browser, reads them, pulls out the exact fact and highlights the sentence it came from on the real page. You watch it work live, with a breathing gaming-style cursor moving over the sites and a step-by-step agent log. Every answer comes with its source link and a word-for-word quote, and if the fact isn’t there it says so instead of guessing. How it works: FastAPI streams each step to the browser. Tavily finds the pages and their text in one search, headless Chromium (Playwright) opens them, Gemini Flash-Lite extracts the answer as JSON with verbatim quotes, and Postgres caches answers and tracks API usage. It runs in Docker on a free Google Cloud e2-micro VM, deployed from GitHub. What we optimized: answers dropped from 34 s to as fast as 5 s, because Gemini reads the search text while the browser opens the page in parallel. Results are ranked by relevance to the question, and model numbers and years must match. Each new question costs 1 search credit and 1–2 Gemini calls, and repeat questions cost zero. Hard caps keep it on free tiers, so it runs for $0. It blocks private addresses, respects robots.txt and treats page text as untrusted. Example: asked for the AMD Developer Hackathon ACT III prize pool on lablab.ai, it opened lablab.ai, answered $17,000+ and highlighted the proof on the page.
