About PulsarPass

PulsarPass exists to answer one kind of question well: “Which is right, and why?” Affect or effect, colour or color, “my family and I” or “me and my family”, what ATP means in a text, how to reply when someone says “I don't deserve you”. These are small questions, but getting them wrong in an email, an essay or a job application costs people confidence.

What makes our guides different

• The answer comes first. Every guide opens with a direct answer and a quick-answer box, so you can get what you need in ten seconds.
• Three countries, not one. Most usage sites write only for American readers. We show what is standard in the United States, the United Kingdom and Australia, and tell you plainly when there is no difference.
• Reasons, not just rules. We explain why a rule exists, where it bends, and where dictionaries or style guides disagree.
• Practice built in. Each guide ends with a short quiz and answers, because the difference only sticks once you have used it.
• One page per question. We don't publish near-duplicate pages. When we improve a guide, we update the original and show the date.

What we cover

We currently publish 60 guides across five areas: confusing words, UK, US and Australian English, meanings and slang, idioms and phrases, and how to respond and other ways to say.

Who writes PulsarPass

The PulsarPass editorial team writes and fact-checks every guide against major American, British and Australian dictionaries and style guides. We focus on one thing: giving you the right word, with the reason behind it, in plain English.
