About Promptai Expand
Promptai provides a unique way for developers to access specific AI models without direct cost. By watching targeted developer-tool advertisements during the idle periods of their AI agent tasks, users earn compute credits.
These credits can then be used to pay for running models like Fable 5, Opus 4.8, and GPT-5.5. This model turns dead wait time into valuable compute resources, making advanced AI accessible directly within IDEs like Cursor and Claude Code.
Advertisers benefit from reaching a highly engaged developer audience, creating a symbiotic ecosystem where compute is funded by attention.
