The checkout said €171.
The final payable total was €218.
That €47 gap wasn’t a calculation error. It was interface design.
Honest Mode is a concept for a browser-side decision layer that helps people see how an interface is shaping their choices before they complete a purchase.
In this fictional airline checkout, the user wants one economy flight with cabin baggage only, no insurance, and no paid seat. Yet the original experience preselects €42 in optional extras, delays €47 in mandatory charges until the final step, introduces unverified urgency, and gives accepting extras far more visual weight than declining them.
Honest Mode first lets the user experience the problem.
Then it scans the interface, identifies five manipulative patterns, connects each finding to visible evidence, separates measurable financial cost from possible behavioral influence, and explains what changed.
But detection is only half of the product.
Honest Mode rebuilds the same booking around the user’s stated intent. Mandatory charges are shown immediately, optional extras are presented transparently, accept and decline receive equal visual weight, cancellation terms are clarified, and every explicit decision is recorded in an Honesty Receipt.
Original payable default: €218 Honest total: €176 Optional defaults removed: €42 Mandatory charges revealed late: €47
The result is not simply a cheaper checkout. It is a decision the user can understand, verify, and confidently own.
Honest Mode is a six-screen high-fidelity prototype built in Flowstep, covering:
01 — Intent capture 02 — Manipulative checkout 03 — Diagnostic scan 04 — Evidence-based X-Ray 05 — Transparent rebuild 06 — Honesty Receipt
The prototype includes connected navigation, selectable findings, dynamic pricing states, explicit consent, and an end-to-end interactive walkthrough.
Built with Flowstep, Flowstep MCP, ChatGPT, and Codex.
Honest Mode is built around one belief:
Interface design should not only optimize conversion. It should protect the quality of the decision.

The €171 to €218 reveal is such a strong way to frame the problem. I really like that Honest Mode doesn’t just flag dark patterns, but rebuilds the same flow around the user’s actual intent. The Honesty Receipt is a great ending too it makes the decision feel clear and accountable. Good luck

Thanks Faadil, appreciate the thoughtful feedback! I wanted Honest Mode to go beyond simply calling out problems and actually rebuild the decision flow around user intent. Glad the Honest Receipt ending resonated with you.
