Oh Boiler is a reusable template tool for situations where you write the same thing repeatedly. Its core idea is: templates are not laziness; bad templates are. A good template is a skeleton, not a costume. It saves you the seven sentences nobody likes writing—the greeting, the setup, the routine closing—and leaves the three sentences that actually matter for you to write yourself.
Purpose
Oh Boiler is for the things you have to write over and over: cover letters tailored to different roles, cold emails tailored to different prospects, performance reviews for different reports, proposals, Monday updates, newsletters, welcome emails, birthday wishes, and so on. It is officially described as "reusable templates for the things you write a second time."
Main capabilities
- Templates and variables: each template consists of a structure plus a set of variables. Variables are placeholders filled in once per recipient, such as name, role, inside joke, specific detail, and so on. The skeleton stays the same; the soul changes. Two filled-in copies will read like completely different letters.
- Built-in template library: official templates built by working writers and refined through hundreds of uses, all available for free. For example, "12-line cold email" (12 lines, 8 variables, finding a reply rather than performing sincerity), "Friday wins email" (three parts, 15 variables), "performance review skeleton" (three groups of strengths, one growth area, closing paragraph).
- AI fill assistance: the Pro plan includes AI fill for any variable. You can paste a job description, a LinkedIn profile, or a company's latest blog post, and Oh Boiler drafts the variable content, which users can edit before sending.
- Recipient memory: the Pro plan provides per-contact variable memory.
- Version history: the Pro plan provides 12 months of version history.
- Integrations: the Pro plan supports Gmail, Outlook, and Notion integrations; the team plan supports native Slack sharing.
- Export: the free plan supports export to clipboard, plain text, and Markdown.
- Browser extension: the free plan includes Chrome and Firefox browser extensions.
How to use it
Users choose a template, fill in the variables for each recipient, and the template body is generated automatically. The official page shows several examples, such as rewriting the boilerplate version of "Hi Sarah, I hope this email finds you well..." into the concise version "Sarah — quick Q2 check-in...", and rewriting a boilerplate cover letter version into one aimed at specific content in the job description.
Use Cases
For those who write the same email two hundred times a year and still get it slightly wrong each time: recruiters, founders, studio leads, account managers, and anyone whose inbox is their work and who quietly gave up on novelty by the fortieth Tuesday. Official mentions specifically for: role-tailored cover letters, prospect-tailored cold emails, report-tailored performance reviews.
Plans and Limitations
Three plans are offered, with no annual lock-in. Free Starter: 5 active templates, unlimited variables per template, export to clipboard/plain text/Markdown, browser extension. Pro: unlimited templates, AI fill assistance (choice of 8 models), recipient memory (variables by contact), 12-month version history, Gmail/Outlook/Notion integrations, priority email support. Team: includes all Pro features, shared template library, brand voice presets, SSO (Okta, Google Workspace), admin controls and audit logs, native Slack sharing. Data is stored in databases in the EU (Frankfurt), and the official statement says user content will not be used to train models; AI fill assistance only sends the prompt content the user explicitly sends to the model the user explicitly selects, and does not retain it. Supports full export of data in plain JSON at any time. Official emphasis: Oh Boiler is different from snippet tools: snippets paste fixed blocks, while Oh Boiler templates hold variables and prompt for filling them in per recipient. The structure is boilerplate, but the soul (the variable content) belongs to the user, and the result reads like a letter. The above information all comes from official materials; specific price figures, cost breakdowns for each plan, the total template limit, or the specific model names for AI fill are not yet provided as further details.
