Yellow Pages

Screenshots, not summaries — deep research agent for nonprofit social service monitoring

Watch Demo

About

Nonprofits spend hours going through thousands of provider websites to keep contact info accurate. Typos and duplicates prevent successful referrals — just over half in one nonprofit I worked with.

Yellow Pages monitors websites, de-duplicates data, and verifies information with a from-scratch deep research agent that's 10x faster and 3x cheaper than OpenAI's. It shows screenshots as proof instead of summaries.

Since my February hackathon, 2 nonprofits have been helped and a 3rd is now using the site, saving hundreds of hours.

Details

Nonprofits manually re-check 5k+ websites quarterly. Missing emails lead to failed referrals.

Solution

Autonomous agents that notify of website changes with screenshot proof and de-duplication.

Impact

Found ~10% of websites with errors across 10k+ providers. Nonprofits save hours prioritizing.

Tech

Custom deep research agent, semantic change detection, headless browser automation.
