Copy Studio

Persuasion built in, proof required

Most tools write whatever you ask for and leave you to worry about whether it is true. This one builds on seven established persuasion levers, then refuses every claim it cannot trace back to something you supplied.

Four fields, two of them optional. The more specific the detail, the less we have to work around.

The seven levers

Drawn from the primary social-psychology literature and cited to source. The rule library, weighting and substantiation model are our own.

Crowd Evidence
Under uncertainty, buyers copy the behaviour of people similar to themselves. Specific, attributable numbers do this work; vague superlatives do not.
Cialdini, Reno & Kallgren (1990), J. Pers. Soc. Psychol. 58(6) — descriptive vs. injunctive norms
Credentials
Buyers defer to demonstrated expertise. The transferable version is a credential you can produce on request, not an adjective.
Milgram (1963), J. Abnorm. Soc. Psychol. 67(4) — deference to legitimate authority
Genuine Constraint
A real limit on supply or time raises perceived value through loss framing. A fabricated limit is the single fastest way to destroy repeat purchase.
Worchel, Lee & Adewole (1975), J. Pers. Soc. Psychol. 32(5) — the cookie-jar scarcity study
Give First
Unrequested value delivered before the ask creates a felt obligation to reciprocate. Free shipping, a sizing tool, a real guide.
Regan (1971), J. Exp. Soc. Psychol. 7(6) — favour-then-request compliance
Small Yes
A small, voluntary, low-friction action makes the larger purchase consistent with a choice the buyer has already made.
Freedman & Fraser (1966), J. Pers. Soc. Psychol. 4(2) — foot-in-the-door compliance
Affinity
Buyers buy from people and brands they like. Origin, faces, and plain second-person language beat corporate register.
Burger et al. (2004), Pers. Soc. Psychol. Bull. 30(1) — incidental similarity and compliance
Shared Identity
Stronger than liking: the buyer and the brand are categorised as the same kind of people. "For X" beats "loved by X".
Tajfel et al. (1971), Eur. J. Soc. Psychol. 1(2) — minimal group categorisation
