How to Simplify a Payslip

Why Payslips Are Confusing

Most payslips are generated by HR software and use industry-standard abbreviations that employees are never taught to read. You might see codes like "PAYE," "NI Cat A," "EE Pension Contrib," or "Basic Sal" without any explanation. Even worse, the layout varies by employer, making it nearly impossible to find a universal guide.

The good news: you don't need a degree in accounting to understand your own pay. Simplifier's AI can read any payslip and explain every term in plain English — including why your net pay is lower than your gross pay, what tax code you're on, and whether your deductions look correct.

Step 1 — Add Your Payslip to Simplifier

Open the Simplifier app on your iPhone. You have several ways to add your payslip:

• Take a photo: Tap the camera icon and photograph your printed payslip. Simplifier reads the text automatically using OCR.
• Upload a PDF: If your payslip is a PDF (common for digital payslips emailed by employers), use the file upload option to import it directly.
• Paste text: If you have a text version, paste it into the text input field.
• Share from Files or Mail: Tap the Share button in another app and select "Simplifier" to import directly.

Your payslip content is never stored on our servers — it's analyzed and discarded immediately.

Step 2 — Choose an Analysis Mode

Simplifier offers four ways to understand your payslip. Here's which one to use:

• Summarize — Gets you the key numbers fast: gross pay, total deductions, net pay. Best for a quick overview.
• Explain — Breaks down every term and line item in plain English. Best when you want to understand what each deduction means.
• Ask — Ask a specific question, like "Why is my tax higher this month?" or "What is my annual salary based on this payslip?" This is the most powerful mode for payslips.
• Simplify — Rewrites the payslip content in clear, simple language. Useful for sharing with someone else who needs to understand it.

Step 3 — Read and Verify Your Results

Simplifier will return a clear breakdown of your payslip. For example, if you use the Explain mode, you might receive:

• "What is my effective tax rate based on this payslip?"
• "Is my tax code correct for a single person with no extra income?"
