Oh Boiler

Reusable writing templates where AI drafts the body and you keep the soul

Variable-driven templates

Save a structure once and swap the personalized details — names, roles, specifics — per recipient, so the body adapts without rewriting.

Eight writing categories

Start from templates for proposals, cover letters, cold emails, reports, newsletters, onboarding, performance reviews, and life-event notes.

AI-assisted body drafting

Let the tool produce the routine parts of a message while you supply the few sentences that carry the real signal.

Boilerplate removal

Strips out the greeting, framing, and obligatory close so your writing sounds like a person, not a form letter.

Strengths & Pros

+Strong focus on reusable structure and variables rather than one-off generation
+Covers eight practical, high-frequency writing categories
+Encourages authentic, personal writing instead of generic output
+Tunable tone for different audiences and industries
