Google Lens Tricks for Students, Shoppers and Travellers

Google Lens is one of those features sitting quietly on almost every Android phone, and most people only use it to scan a QR code or figure out a plant in their balcony. Which is a shame, because it can do a lot more.

I use it almost daily – to copy text from a printed notice, translate a menu in Chennai, or figure out where someone bought a lamp. Here are the tricks I find genuinely useful, with steps.

Where to Find Google Lens

Depending on your phone, Lens hides in a few places:

• Google app – tap the camera icon in the search bar.
• Your camera app – many Android phones have a Lens button or mode built in.
• Google Photos – open any photo and tap the Lens icon at the bottom.
• Chrome – long-press an image and choose Search with Google Lens, or use the Lens icon in the address bar.
• Circle to Search – on supported Android phones, long-press the home button or navigation bar and circle anything on your screen.
• iPhone – use the Google app or Google Photos app.

For Students

1. Copy text from printed notes or books

This one saves so much typing.

1. Open Lens and point it at the page.
2. Tap Text at the bottom (or just tap on the text).
3. Select the lines you want, then tap Copy.
4. Paste into Google Docs, WhatsApp or your notes app.

Bonus: Lens has an option to Copy to computer if you’re signed into the same Google account in Chrome on your laptop. Super handy for assignments where you need to quote a few lines.

Handwritten notes work too, if the handwriting is reasonably neat. Mine doesn’t always qualify.

2. Get help understanding a homework problem

Point Lens at a maths, physics or chemistry question and tap Homework (where available). Lens shows explanations, related videos and step-by-step help from the web.

Honest warning: use it to understand the method, not just copy the answer. Exams don’t come with Google Lens. Try the problem first, then use Lens when you’re stuck.

3. Translate notes or study materials

Got a reference in Hindi or another language you’re not comfortable with? Tap Translate and Lens overlays the translation right on the image. You can pick the source and target languages at the top.

4. Identify diagrams, historical buildings, or specimens

For biology or geography projects, Lens can identify plants, insects, rocks and landmarks. Treat the result as a starting point – then verify from your textbook.

For Shoppers

5. Find where to buy something you saw

See a nice kurta in a friend’s photo? A lamp in a café? Open Lens, point it (or open the photo in Google Photos and tap Lens), and tap Search. You’ll see visually similar products with shopping links.

Tip: crop the selection box tightly around the item. Otherwise Lens might focus on the background.

6. Compare prices

After a Lens search, scroll the results – you’ll often see the same or similar item listed across different shops with prices. It’s a quick way to check if a store price is fair.

Just be careful with unknown websites offering very low prices. If a site you’ve never heard of is selling branded shoes at 80% off, that’s often a scam. Stick to known sellers.

7. Scan barcodes and QR codes

Lens reads barcodes on products and QR codes on posters or menus.

Safety note: before opening a QR code link, look at the URL Lens shows. If it’s a strange-looking website, don’t open it. And never scan a QR to “receive money” – that’s a UPI scam trick.

8. Check reviews of a book or product

Point Lens at a book cover or product packaging to bring up reviews, ratings and details.

For Travellers

9. Translate signboards and menus instantly

This is my favourite. Point Lens at a signboard, menu or notice in another language, tap Translate, and the translated text appears right on top of the image.

It works for many Indian languages – useful when you’re travelling to another state – and lots of international ones.

For travel without good internet: install the Google Translate app and download offline language packs before your trip. The Translate app’s camera mode works even without data for downloaded languages.

10. Identify landmarks and places

At a monument or old building, point Lens at it to see the name, history and related information. Nice for those “what is this place?” moments.

11. Save contact details from visiting cards

Point Lens at a business card. It can detect phone numbers, emails and addresses – tap to call, email, or add to contacts.

12. Find out what a dish is

Point Lens at a dish (or a photo of it) to get its name and recipes. Results aren’t always perfect, but it’s surprisingly good with common dishes.

Everyday Tricks

13. Identify plants, flowers and pets

Lens can tell you the plant species in your balcony or a dog’s breed. For plants, check results with another source before eating or touching anything unfamiliar.

14. Solve “what’s this cable/part?”

Got a random charger or cable in a drawer? Point Lens at it to see what it is. Same for spare parts – helpful at a hardware store.

15. Use Circle to Search on screenshots

On supported phones, circle something in a video, Instagram post or chat to search it without leaving the app. Great for “what’s that song / place / shirt?”.

Privacy: What to Know

• When you use Lens, the image is sent to Google for processing. Don’t scan sensitive documents like Aadhaar, bank cards or passwords.
• Lens activity may be saved in your Google Activity (myactivity.google.com). You can view and delete it there, or turn off saving.
• Be mindful when pointing Lens at people. Lens is designed not to identify random people by face, and you shouldn’t try to use it that way.

When Lens Gets It Wrong

Lens is very good, but not perfect:

• Blurry or dark photos give poor results. Use good light and hold steady.
• Handwriting can be misread – double-check copied text.
• Translations can miss context or local slang. Fine for menus and signs; not great for legal documents.
• Plant and mushroom identification can be wrong. Never eat something based only on a Lens result.

Small Habits That Make Lens Work Better

A few things I’ve learned from using Lens almost every day:

• Clean your camera lens. Sounds silly, but a smudged lens from your pocket makes text recognition noticeably worse.
• Hold the phone parallel to the page. Tilted angles distort text, and Lens copies it with mistakes.
• Use the crop handles. Drag the corners to select just the part you care about – one paragraph, one product, one word.
• Try a screenshot instead. If Lens struggles live, take a photo first, then open it in Google Photos and use Lens there. Steadier image, better result.
• Check your language settings. For translation, set the source language manually if auto-detect keeps guessing wrong.
