About Ohboiler - AI-Powered Custom Templates
What Is Ohboiler
Ohboiler (ohboiler.com) is a set of free writing tools for the documents people put off writing: a resignation letter, a LinkedIn summary, a slogan, a city name spelled right in a cold email. You fill in a few fields, pick a tone, and the page returns text you can actually send. It runs in a web browser, with no account and nothing to install.
The method is custom templates rather than open-ended chat. Every tool carries a finished structure written in advance, and your answers fill the variable slots: your role, your company, your notice period, whether you want to give a reason. That's where the AI template generator label comes from. You get the same clean shape every time, and you give up the freedom to ask for something the template was never built to hold.
The limits follow the same design. There's no long-form assistant here, no saved history and no export pipeline. Close the tab and the draft is gone unless you copied it out. If your task is a cover letter rewrite or a resume overhaul, Ohboiler sends you to its guides and tool comparisons instead of writing the file for you.
Getting Started
- Open the tool for your task. The resignation letter generator, slogan generator, LinkedIn summary generator and city name generator each sit on their own page.
- Fill in the facts. Name, manager, company, job title and date for a letter. Empty fields show a bracket where the detail goes, so you won't send a blank by mistake.
- Set the options. Choose a tone, add a notice period in weeks, and switch the reason, the thank-you or the handover offer on or off.
- Read the result out loud. Change any line that doesn't sound like you, then copy the text into your email client or document.
- Check the numbers. The resignation letter generator shows your last working day and moves a weekend finish to the following Monday.

Key features
Custom templates with fixed structure and open variables
Each tool runs on a pre-written skeleton, and the fields you fill decide what lands inside it. The resignation letter keeps five parts in the same order regardless of length: the decision, the date, an optional reason, thanks, then the handover. That structure is why the output reads clean on the first pass and why you don't need to edit for coherence.
Three tones from one set of answers
Warm, neutral and brief share the same skeleton, so switching tone doesn't change the facts or the order. You can put the two versions side by side and pick the one that matches your manager. For slogans, the range widens to four tones and six lines per run, which is enough to see a direction before you commit.
Notice period math done for you
Instead of leaving you to count backwards from a calendar, the resignation letter generator adds whole weeks to your letter date and prints the resulting last working day. If that day lands on a weekend, it shifts to Monday and tells you it did. Anyone who has argued with HR about the exact end date will recognize the value.
Optional sections you can switch off
The reason, the thank-you paragraph and the handover offer are toggles, not fixed text. Turn any of them off and the letter closes up without a dangling sentence where the paragraph used to be. That's the part most template libraries get wrong: they leave a gap that reads like an editing mistake.
Drafts that never leave your browser
Ohboiler assembles the text in the page from the fields you typed. Nothing is sent to a server, and there's no email capture, no account and no cap on how many versions you produce. Close the tab and the content is gone. For a resignation, where a leaked draft becomes something you have to manage, that matters more than a saved history would.
Pages built to be read by AI agents
Every page on the site has a plain markdown twin: add .md to any URL and you get the clean version. There's also a site index at /llms.txt, an open sitemap and no authentication. If you run an assistant that pulls references, Ohboiler is one of the few free writing tools that hands over structured text instead of a wall of markup.
Pros and cons
Pros
- Free to use with no signup, no email capture and no limit on the number of versions.
- Output keeps a fixed, editor-written structure, so the first draft is usually sendable.
- Notice period and last working day are calculated, including the weekend shift to Monday.
- Text stays in the browser, which suits sensitive documents like a resignation letter.
- Markdown versions and an open site index make the pages easy to pull into an AI workflow.
Cons
- Scope is narrow: the tools cover a resignation letter, a slogan, a LinkedIn summary and city names, not full documents like a cover letter or a resume.
- Generation is template-driven, so you can't ask for a length, a format or a detail the skeleton doesn't include. You edit around the template instead of directing it.
- Nothing is saved, so there's no draft history and no way to return to a version you closed, unless you copied it out first.
- No mobile app and no team features: sharing means pasting the text into your own tools.
Frequently asked questions
Yes. Every tool runs without payment, without a signup and without an email address. There's no cap on how many letters or slogans you generate, and no paid plan sits behind the free one.
