Preflight tells you whether a campaign can run. Review tells you whether it will get you anywhere: does anyone get a message after accepting, does any message ask for a next step, do the messages say what you sell, who is left with nothing. The Campaign review panel in the Builder: the readiness bar and bottom line, then Stops the goal and Would work better, with a message shown Now and Suggested

Open Review

In the campaign’s Builder, click Review in the toolbar. The number on it is how many problems there are (in red) or, when there are none, how many tips (in gold); a check mark means nothing was found. It is checked again on every change, so the number goes down as you fix things.

Read what it found

At the top, a bar with three parts and the bottom line: Won’t work as it is (one part, red), Needs work (two) or Ready (three, gold), with the AI’s sentence when it has given its opinion. Below, what to fix in two groups: Stops the goal (for example: people who accept never get a message, or no message asks for anything) and Would work better (a follow-up, a path for people who don’t accept, a message that names your offer). Each line says what is wrong and what to change; the step’s name at the right of the line opens it. Lines from the AI have a small sparkle.

Fix in one click

  • Add a follow-up: adds a wait and a follow-up message after the step, and opens it so you can adjust the text.
  • Add a follow and a like: people who don’t accept your invitation get a follow right away and a like 5 days later, so they still see you.
  • The step’s name (for example Message (step 4)): opens the step to change it.
  • Tell Kerux what you sell: opens your business profile (Settings > Business profile). Without it, nothing can check that the messages fit your offer.

Ask the AI for its opinion (Pro)

Click Ask the AI for its opinion. The AI reads the whole campaign and your business profile, and tells you the goal it sees, an honest bottom line (Ready, Needs work or Won’t work as it is) and up to five things to change. For a weak message it writes a new one: See the text shows the step’s text Now (struck through) and the Suggested one, and Use this text puts it in the step. Nothing changes until you click. The AI’s opinion is part of Pro, Agency and the free trial; viewers don’t see the button. If the AI isn’t available or can’t answer, the panel says so and the checks above still apply.
Review opens by itself once: when the AI or a template has just built the campaign and has something to say, or when a campaign has a problem. After that, the number on the button tells you. A campaign you just created, with nothing but its Start, isn’t checked yet: the Review button shows no number, Review shows no problems, doesn’t open by itself and says Add your first step. Kerux then checks the campaign as you build it: whether people get a message after accepting, whether you ask for a next step, whether the messages say what you sell. On a campaign the AI or a template just built, if your AI is set to proactive (Preferences > AI assistant), the AI’s opinion runs by itself. Each AI opinion uses about one AI credit.
If you change the campaign after the AI’s opinion, Review says so: click Analyze again to update it. The checks themselves are always up to date and never use credits.
