Heyflow vs. Knak

Heyflow is the AI-first funnel platform for performance marketers, agencies, ecom brands, and growth teams. Building a funnel or landing page is no longer the hard part: turning paid traffic into real revenue, leads, and bookings is.

Knak is the AI production layer for enterprise marketing. The system between creative brief and send, where your team and AI build on‑brand campaigns that are more personalized, more tested, and live in days.

Collaboration, feedback, and structured approvals happen inside the same system where the work gets done, not across Slack threads, annotated PDFs, or disconnected tools.
