The difference between output and correspondence.
Patron researches the prospect, frames the strategy, and drafts in CASL's voice. It shows the reasoning and the letter together, with a coded check of anything that would stop it sending: an invented number, an unverified fact, a missing citation, a machine tell. Codified craft, not generic AI.
What Patron shows you: the brief, the letter beside it, and a short list of anything that blocks sending. Heavier diagnostics stay in a drawer.
The dossier, the strategy, and the keystone: the one fact true of this donor alone. You read the letter against it.
In CASL's voice, every donor claim cited to the dossier. A discovery check rewrites any line that isn't both unexpected and true.
One verdict, hold or clear, on what stops a letter: placeholder text, a broken citation, an unverified fact, an off-scale ask.
The ten craft passes, the donor simulation, and the vital-signs charts. To consult, never the product.
A draft is easy. The seam a fundraiser spots in two seconds is the hard part. Deterministic checks, not tone scoring.
Tests the purpose against the verified facts before drafting. Name a wing the plan doesn't list, and it flags that first.
Any number that traces to no source in the dossier or your inputs holds the letter. This catches an invented statistic.
No leftover scaffolding, no empty fields, no citation dropped by an edit.
A CASL fact outside the verified set, an unconfirmed wing, a superlative, holds the letter until a person clears it. Enforced in code.
Em dashes, the antithesis button, stock flourishes. A regex scan. A stray em dash holds the letter on its own.
An unresolved source conflict, or an ask out of scale with the campaign. The numbers and the sources have to agree.
Accept changes and rebuild, and Patron re-scores the whole letter, showing what improved and what got worse before you send.
Donor focus, concreteness, hedges, and tells, scored before and after every rebuild. A change that makes it worse is visible before you send.
Every rewrite pass obeys the writer's fact rules, so a later edit can't slip in a number the draft was forbidden to invent.
Most AI tools for fundraising train on what already exists on the open web. Patron trains on the practitioners who codified the craft.
Every draft uses the names CASL uses internally, never generic nonprofit copy.
