Every time your AI needs live and accurate information, it has to do web searches, which cost thousands of tokens and does not guarantee accuracy or freshness.
havdu replaces the search with one focused and efficient fetch.

What this looks like
Without havdu
"Is it going to be sunny today?"
Your AI runs a web search. Opens 5–20 pages. Pulls thousands of tokens of HTML, ads, navigation, related-stories widgets into context. Spins for 10–30 seconds. Returns a confident answer with no clear source. Two chatbots, same question, often give conflicting answers. You can't tell which is right.
With havdu
"Is it going to be sunny today?"
Your AI fetches havdu.com/q/weather/your-city. One call. ~700 tokens in. Under 2 seconds. Returns the forecast with a named source and a timestamp from minutes ago. Same question, same chatbot, deterministic answer.
Same question, same chatbot. One fetch instead of a crawl.

How to use it
01 Paste a snippet into your chatbot's custom instructions. Once. You never have to do it again.
02 Ask about live data normally. Your AI will fetch havdu instead of crawling the web.
03 If your AI can't fetch URLs directly, it will show you one to paste back. Works every time, regardless of whether havdu is indexed for your query yet.

Who this is for

Built for

AI power users who ask about live data a lot. Builders making agents who don't want to wire up six APIs for casual queries. Anyone whose chatbot keeps spinning for 20 seconds to tell them today's weather.

Not built for

Mission-critical systems. Commercial products. Anyone needing uptime guarantees. Anyone whose AI's native tools already handle the query well.

Before you rely on it

havdu is early. It's free, run by one person, depends on third-party providers, and will sometimes break. The verticals above all work today. If you're using havdu for anything you can't afford to be wrong about, verify against the source.
