It can't make things up.

The assistant knows nothing on its own. It reads only the structured official record, cross-references real data points, and shows the source behind every answer — so it can't invent a vote, a quote, or a bill that doesn't exist.

$8/mo — the AI assistant

It runs on a real model, and every question it answers costs real money. So instead of ads, data sales, or paywalling public records, we charge the people who use the expensive part. That's what keeps the record free and the project independent — no ads, no lobbying money, no selling your data.

Keep the record open. Ask it anything.

Independent, nonpartisan. No ads, no paywalled public data.
