Fair or Dark — the psychology in your marketing copy, honest or not

Paste one landing page, pricing page, email, checkout or popup and pick the challenge it is failing at. Free in your browser: the psychological principles it pulls and the dark patterns it risks (a countdown, a shaming 'no thanks', a pre-ticked add-on, a hidden fee), every price per day and the Rule of 100 framing. Then a map lane rates each principle working, weak or misused and honest or not, and an apply lane writes honest rewrites and A/B tests.
