Frigade, a YC W23 startup, has released an Assist API that gives in-app AI agents a single tool call to generate on-screen visual guides instead of relying on outdated help-center text or web searches. The tool uses a browser-based agent trained on a test account to understand a product's UI, then either produces a step-by-step visual walkthrough, returns a conceptual explanation, or declines if it can't help.
