Oh Boiler

Oh Boiler is a writing tool that turns repetitive letters into reusable templates with named variables. Save the structure of a cover letter, cold email, proposal or performance review once. Each new send is just what changes — the recipient name, the specific detail, the paragraph that is yours. AI handles the boilerplate. You write the soul. Browser extension for Gmail and Outlook included. Built in Lisbon by a four-person studio. The one feature we will not ship: auto-send.
