Oh Boiler

Oh Boiler stores the structure of every letter written well, so the next ones go faster without sounding generic. It focuses on the writing adults do repeatedly, offering templates that separate the boilerplate from the personal contribution. The tool emphasizes keeping the voice and the structure while reusing the shared framework across messages.

It is built as a tool for people who write the same emails many times a year, such as recruiters, founders, studio leads, and account managers. It aims to preserve the writer’s voice while avoiding repeated boilerplate, so letters feel like they were written by a human each time.

The product presents templates as a skeleton with variables that adapt to the recipient. Users fill in placeholders like names, the role, and a specific detail once per recipient, and the body is generated while the soul remains the writer’s.

Oh Boiler combines a structured template engine with per-recipient memory and brand voice presets, and it integrates with common writing apps to fit into existing workflows.
