Editorial Policy

Probably Useful publishes guides to help people understand the tasks behind our tools. Our goal is practical, accurate content written in plain language.

How we choose topics

We focus on questions that naturally support a useful task: how a calculation works, what a technical format means, how to avoid a common mistake, or what someone should know before using a tool.

Sources and verification

When a guide depends on rates, rules, specifications, or other factual information that can change, we prefer primary and authoritative sources such as government agencies, official documentation, standards bodies, and the provider responsible for the information.

We may also use reputable secondary sources for context, but important claims should be checked against the strongest source reasonably available.

Writing and editing

Content is written for clarity first. We avoid adding length simply to make an article look comprehensive. Examples should be realistic, formulas should be shown when useful, and limitations should be stated when they could affect the result.

Updates

We aim to review content that can become stale. An article may be updated when a rate changes, a product changes, a better source becomes available, or a reader points out something that needs correction.

Corrections

If we find a material error, we aim to correct it promptly. If you believe something is incorrect or misleading, please contact us with the page URL and the detail you think should be reviewed.

Commercial relationships

Probably Useful may earn revenue from advertising, sponsorships, affiliate links, or paid partnerships. Commercial relationships do not change the formulas used by our tools or the standards we apply to factual content.

When content contains a material affiliate or sponsored relationship, we aim to disclose it clearly enough for readers to understand the relationship.

Artificial intelligence and automation

Automation and AI-assisted tools may be used as part of research, drafting, coding, or editing workflows. Content should still be reviewed for usefulness and accuracy before publication. We do not consider automated generation a substitute for verification.
