promptbl.ai is the unified ad layer for AI conversations. Publishers monetize their chat surfaces with native, contextual placements. Brands buy ads across every LLM in one console.
Every placement is keyed to the user's exact question — typeset into the model's response, in milliseconds, with the same reporting layer brand teams already use everywhere else.
We sit between advertisers and AI publishers — analyzing prompts, scoring intent, ranking ads, and deploying the most relevant placement back into the model's response. In milliseconds. With receipts.
A high-performance bidding stack that monitors prompts, evaluates intent, and deploys the most relevant ad — natively typeset into the model's response — in under 40 milliseconds.
AI conversations are the highest-fidelity demand signal ever shipped on the open web. promptbl turns prompt-level signals into actionable audience insights — emerging categories, unmet needs, competitive gaps, all updated in real time.
We're onboarding 30 launch partners through Q3 — brands, agencies, and publishers. Tell us about your buy or your surface and we'll route you to the right team, usually within a day.
