Twelve working mock interfaces that demonstrate real manipulative design patterns, each with its ethical counterpoint.
Each card below is a working mock interface, not a picture of one. The buttons, timers, counters and checkboxes all do something. Interact with a card and read the tactic, the exploit, and the ethical version it produces. All of the interfaces and copy here are original - no real product is depicted.

Six cover-letter templates driven by a pasted job description, with a real ATS keyword-match readout that stems and de-duplicates, plus an ASCII-safe plain-text export.

Spaced-repetition decks that live in your browser.

APA 7, MLA 9, Chicago 17 and Harvard from one form for books, journal articles, websites and reports, with each style's own author rules and a BibTeX tab.

Plain text CV in, styled PDF out.

Run a pattern live against sample text: every match with its position, numbered and named capture groups, a match count, and a replacement preview.

Decode a JWT header and payload without verifying the signature, with base64url handled correctly, the algorithm flagged as claimed-only, and an expiry check.

A real entropy estimate in bits from character-class pools with a repetition penalty, an estimated crack time, a common-password list check and a live verdict.

Batches of UUID v4 values from the browser's own CSPRNG, plus CRC32, FNV-1a and DJB2 of any text with both hex and decimal output.
