Introduction

Hi, and welcome back. After PDFs and spreadsheets, we now give Claude the easiest kind of file to make: images. We'll turn a receipt photo into a table, understand an error screenshot, turn a whiteboard photo into meeting notes, review a product photo, and learn the limits and privacy rules.

Step 1: What can be read from an image

Every day we photograph receipts, save screenshots, and snap the whiteboard after meetings. They all hold work information, but rarely get processed any further. Claude can read those images. It recognizes text and numbers, understands app screens, and explains what it sees in a photo. It works just like attaching a PDF: click the attachment button or drag the image in. Screenshots can usually be pasted straight from the clipboard, too. Five kinds of images are useful most often. First, photos of receipts and bills, which can become an expense table. Second, app screenshots and error messages, which can be explained in everyday language along with steps to fix them. Third, photos of a whiteboard or handwritten notes after a meeting, which can be tidied into meeting notes and a task list. Fourth, charts or tables saved as images, for example from someone else's report, whose numbers can be pulled out to work with. Fifth, product photos, which can be reviewed for lighting and composition, and given a caption. Let's practice four of them, one at a time.

Step 2: A receipt photo becomes an expense table

First practice, with Laras. She photographs a receipt for ingredients from the market, then asks Claude to turn it into a table and flag any numbers that aren't clear. Claude reads the receipt image. The result is a four-row table: UHT milk, palm sugar, plastic cups, and ice. Notice the question mark in the palm sugar row. The seller's handwriting isn't clear, so Claude isn't sure between thirty-two thousand and thirty-eight thousand. Laras looks at the original receipt. The price is thirty-eight thousand. Claude updates the palm sugar row to one hundred fourteen thousand, and the total spent to four hundred fifty-seven thousand rupiah. Asking Claude to flag unclear numbers is very important. Without it, Claude might pick one of the numbers without telling us. Laras copies the table into her October expense spreadsheet. Four new rows go in at once, without retyping them one by one. Then she adds them up with a SUM formula. The result is four hundred fifty-seven thousand, matching Claude's calculation and the receipt. Imagine handling every receipt like this. By the end of the month, Laras has a complete expense record that she can later compare with her sales data.

Step 3: A screenshot of an error message

Second practice, with Dewi. Her office stock app shows an error message while importing data. Dewi isn't an IT person, so she takes a screenshot and asks Claude. Claude reads the screenshot. Claude explains that a date in row fifteen has a different format, then gives three safe steps. Notice the final note: don't delete any data in the app. Dewi tries, but the import still fails. She doesn't force it, and asks Claude to write a message for the IT team instead. Claude writes a clear message: what the error is, which steps were tried, and the result. The IT team will be very grateful for a report like this. One important habit: before taking a screenshot, close or mask sensitive information such as balances, passwords, and customer data that happens to be on screen. From Dewi's example, there are three sentences worth writing every time. First, I'm not an IT person. With this sentence, Claude explains without confusing technical terms. Second, what steps are safe for me to try? The word safe makes Claude avoid suggestions that could delete or damage data. Third, when should I stop? That way you know your limit, and ask the IT team or the app provider for help before the problem grows. These three sentences work for any app, from a cashier app or accounting software to the office printer settings.

Step 4: Whiteboards and product photos

Third practice. After the warehouse meeting, the whiteboard is covered in scribbles. Dewi photographs it and asks Claude to tidy it into meeting notes with a task table. Claude reads the whiteboard photo, including the handwriting and the arrows. The right panel shows the meeting notes: three decisions and a task table with who, which task, and the deadline. Claude also honestly notes that some writing is cut off in the corner of the board. Dewi checks the deadlines and owners, then shares the notes with the team. A whiteboard photo that would usually be forgotten in the phone's gallery is now a clear task list. A small tip: before erasing the board, photograph it straight on from the front, and make sure the whole board fits inside the frame. Fourth practice, with Nadia. She photographs the Sunset Coffee gift hamper and asks for a photo review for Instagram, three suggestions, and one alt text. Claude gives three practical suggestions: window light, a plain cloth background, and an angle slightly from above. There's also alt text, a description of the image that screen reader apps read aloud for blind users. Nadia reshoots the photo with those suggestions, then pastes the alt text into Instagram's upload settings. The Sunset Coffee account becomes friendlier for every reader.

Step 5: Image limits and privacy

Now the limits. Blurry, dark, or tilted photos make letters and numbers easy to mix up. The fix is simple: reshoot it straight, with enough light. Handwriting is easy to misread, like the palm sugar price earlier. Always ask Claude to flag anything it's unsure of. Small or dense numbers, such as a long receipt, can lose digits. Crop the image into sections so they're clearer. Long tables in an image can lose rows. Match the number of rows in Claude's result against the number of rows in the image. The more important the number, the more you must check it. For money amounts, always match them against the original receipt or document. Finally, privacy. Don't upload photos of ID cards, passports, bank cards, or credit cards, even just to read one number. Don't upload screenshots that show passwords or OTP codes. An OTP code is a secret one-time code sent by text message or an app. Don't upload photos of other people's faces without permission, including photos of customers or coworkers. Be careful with transfer receipts that show customers' account numbers, too. Claude doesn't need data like this. If an image still needs reading, mask the sensitive parts first, or use a different, safe image. Claude's data policy can change, so read Anthropic's official pages. The screens in this video are simulations.

Done!

We've turned a receipt photo into an expense table, understood an error screenshot, tidied a whiteboard photo into meeting notes, reviewed a product photo, and learned the limits of images and the privacy rules. In the next episode we give Claude two files at once to compare, such as two supplier quotes or an old and a new version of a contract. See you there!
