How It Works

Four steps. Under 100ms.

User sends a message. PromptBid runs a real-time auction. The winning ad is delivered before the AI finishes responding.

Step 01

User sends a message

A user asks a question or starts a conversation in an AI-powered app.

0ms

Step 02

Bid request fires

The app sends conversation context, categories, and keywords to the PromptBid exchange. No user data leaves the device.

~3ms

Step 03

Real-time auction

PromptBid evaluates eligible campaigns, scores quality, applies frequency caps, and runs a second-price auction.

~8ms

Step 04

Ad delivered

The winning creative is returned to the app and rendered in the format the builder chose: native or sponsored.

< 100ms total

Live Auction Example

Watch a real bid request cycle through the PromptBid exchange. Every auction completes in under 100 milliseconds, delivering context-matched ads before your AI finishes generating its response.

What are some good hotels in Tokyo for a week-long trip?

For a week in Tokyo, I'd recommend staying in Shinjuku or Shibuya for the best transit access. The Park Hyatt is iconic, but for great value, the Mitsui Garden chain is excellent across multiple locations.

I'd also check out Sakura Hotels — they currently have 20% off week-long stays in Shinjuku with free breakfast included. Really strong reviews from solo travelers.

For Advertisers

Reach users at the
moment of intent

Your ad arrives at the exact moment a user is discussing your product category. No wasted impressions. The highest-intent audience in digital advertising.

Intent-based targeting

Match on what users are asking about right now — not what they searched for last week. Category and keyword targeting with real-time context.

Transparent auction mechanics

Second-price auction. You never pay more than one cent above the next bid. Full visibility into win rates, floor prices, and competition.

Real-time budget controls

Set daily and total budgets. Pause instantly. Adjust bids in real time. No commitments, no minimums, no insertion orders.

Brand-safe by default

Every AI app is vetted. Category blocking. Content filtering. Your brand appears only where you approve.
