Plain-words pages on keeping private things private: what staff paste into artificial intelligence, and how to black out a document so it stays blacked out. If you are not sure where to start, start with the copy-paste test.

When trust is built to be used later

Slow-burn romance and investment scams, pages that change what they send, and warnings that mix true advice with false claims, with four habits that work against all three.

One rule for any request for money

One line to use before money moves, and how it applies to a bank message, a supplier, a relative, a recruiter and an offer to get money back.

Turn on two-step login

What a second check is, where to start, which kinds are stronger, and links to the official steps for Google, Apple and Microsoft.

The copy-paste test is not enough

Everybody checks a blacked-out document by trying to copy the words out of it. That test catches the most common mistake and misses eight others. Read this one first.

The free tools

Is It Really Blacked Out? — drop in a PDF (Portable Document Format) file and it shows what anyone could still get out of it.

Hide Names from artificial intelligence — use any artificial intelligence on a message about real people without handing over their details.

Check what you send to an artificial intelligence — spots names, numbers and passwords before you press send.

Prompt injection checker — before an artificial intelligence reads a web page, email or document for you, check the text for hidden instructions aimed at it.

Invisible character remover — find and remove zero-width spaces, hidden messages, look-alike letters and tracking codes in copied text.

Before You Pay — check a payment page or a message asking for money before you pay, and stop payments nobody agreed to.

Before You Invest — check a trading, crypto, forex, loan or pension offer for the tricks financial regulators warn about, and find the official register of firms in your country.

Can I Afford This? — what a loan, a credit card or buy now pay later really costs, a pay planner, and two ways to pay off debts compared.

Before You Buy a Course — check a money-making course, coaching offer or side hustle for the warning signs regulators describe, and see how many sales it takes to earn the price back.

Subscription Check — find every repeat payment on your own statement, the yearly total, overlaps and price rises, and how to cancel.

Sort My Saved-for-Later Reading — newsletters, saved emails, bookmarks and notes mixed into one document sorted by your topics, without giving anyone your email login.

Delete My Details — write to a company that holds your details and ask it to show you or delete them.

How the paid tool works

How Redaction Studio works — why it turns each page into a picture, and what that costs you.

What each check looks for — the ten places words can hide inside a PDF file.

Every tool runs on your own phone or computer. Turn the internet off and it still works. None of them certifies anything or makes anybody compliant with any law.
