| Which plan to pick | Basic does the job for a solo marketer or founder who wants a serious swipe file. Step up to Workflow when you have a team or you want to track specific competitors and connect it to Claude. Agency only makes sense if you brief for many brands. | 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. | 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. |
