Oh Boiler

Oh Boiler is a writing tool for anyone whose inbox is their job. Its central idea is that templates are not lazy — bad templates are. A good template is a skeleton rather than a costume: it removes the sentences nobody enjoys writing (the greeting, the framing, the obligatory close) and leaves the few lines that actually carry meaning for you to write yourself. The product's tagline captures this balance: AI writes the body, you write the soul.

In practice, each template is a structure plus a list of variables. You save the structure once, then fill the variables — names, roles, a specific detail, an inside joke — differently for every recipient, and the body adapts automatically. Because two filled-in copies read as genuinely different letters, you can send many personalized messages without retyping the same spine. Oh Boiler ships with eight starting categories: business proposals, cover letters, cold emails, reports and weekly updates, newsletters, customer onboarding, performance reviews, and birthday or life-event messages.

Oh Boiler positions itself for people who write the same email hundreds of times a year: recruiters, founders, studio leads, and account managers. Pricing is a paid model detailed on its pricing page. The tool also emphasizes craft — it argues that the only sentences worth writing fresh are the ones with the specific detail that makes a reader pause.
