AI ad network

Gravity is an example. It describes itself as an ad network for AI: brands reach people inside conversations with LLMs, agents, chatbots and AI search, and the host apps earn from the ads. It lists the kinds of places ads appear, namely chat apps, coding assistants and IDEs, consumer AI apps and AI search, but names no specific publisher apps. Gravity claims 20+ AI platforms and 1B+ users across the network; both figures are self-reported.

Matching is contextual. Gravity compares recent conversation messages with active campaigns, runs an auction and returns the winning ad. Ads show only on websites and apps Gravity has verified, and when a Gravity ad is on screen no other ad can be. Formats in Gravity’s docs include text, server-rendered designs, images, rich frames and product carousels, all carrying a “Sponsored” label, although its FAQ lists only two formats.

A network can also deliver beyond its own publishers. Gravity campaigns have a network mode that can include partner delivery on OpenAI; OpenAI-only delivery needs account access.

Buying an AI ad network means buying context, not specific apps: you can choose countries, devices and an English-only option, but not individual publishers. Gravity bills per 1,000 impressions, or per attributed conversion where the account allows it, and offers no click billing for new campaigns. There is no minimum spend. Expect a learning period of up to 30 days, or 2 to 3 months for Conversions campaigns. Through Admux, the Gravity leg draws from the same prepaid balance as your ChatGPT and Google legs, and runs under your scoped Admux key instead of Gravity’s single full-access account key.
