| Which plan to pick | Start on Free and let the read-only agent audit one account for a fortnight. Copilot is the sweet spot for most small brands, because the analysis is the valuable part and you can make the edits yourself. Go to Operator once you trust its suggestions enough to approve them from your phone. | Plus on the yearly plan is where the value is: research and analytics for one brand at a price close to Foreplay alone. Add the Ad Launcher only if you launch dozens of ads a week by hand today. The Creative Hub on its own is hard to justify when Google Drive and Slack exist. | Start on Free and build your welcome and abandoned cart flows before you pay anything. Move to Email when you cross 250 contacts, and only add SMS once email is working, because text messages cost extra per send. |
