How to use Lens Gemini: there isn’t one button called “Lens Gemini”, but Google Lens and Gemini now work together in several places. You can use either one to ask questions about a photo, your screen or the world in front of your camera. Lens is best for fast identification and translation. Gemini is best for a back-and-forth conversation about what it sees. This guide explains each route on Android, iPhone and Chrome, when to choose which, and what to do when a feature is missing.
How to use Lens Gemini: the short answer
Open Google Lens, point it at something or upload a picture, then ask a question in AI Mode. For longer conversations, send the same picture to Gemini. On Chrome for desktop, use “Ask Gemini” and the “Select from screen” tool to draw boxes around anything on a page. Menus change often and some features arrive country by country, so use the steps below as a guide rather than a script.
Key takeaways
- Lens identifies objects, translates text and finds matching products or pages quickly.
- Gemini keeps a conversation going, so you can ask follow-up questions without starting again.
- Lens works with AI Mode, which can ask several searches at once about the objects in your photo.
- Chrome on desktop has a Gemini tool for selecting parts of your screen.
- Availability depends on your device, language and country.
Lens or Gemini: which should you use?
| Situation | Better choice | Why |
|---|---|---|
| “What plant is this?” | Lens | Quick match with web results |
| Translate a menu or sign | Lens | Built-in translation, including live view |
| Find where to buy something | Lens | Strong at product and web matching |
| Explain a chart or diagram, then ask more | Gemini | Follow-up questions in one chat |
| Work through a maths or science problem | Gemini | Step-by-step explanations |
| Analyse a recorded video clip | Gemini | Lens Live works on a live camera, not saved clips |
| Keep a saved history to return to | Gemini | Chats stay in your history |
These differences come from a hands-on comparison published by Android Police in June 2026. Its author found that Lens is quick and frictionless for identifying things, while Gemini wins on follow-up questions and multi-step problems. Gemini’s answers on details such as counts weren’t always accurate, so check anything important.
Method 1: ask Gemini about a photo in Google Lens (AI Mode)
Google brought AI Mode into Lens in April 2025, and it keeps getting wider. The idea is simple: Lens sees the objects, and AI Mode runs several searches about both the individual items and the whole scene.
- Open the Google app or the Lens app on your phone.
- Tap the Lens icon in the search bar, or open Lens directly.
- Take a new photo or choose one from your gallery.
- Type your question, or hold the shutter button and speak it.
- Read the answer, then ask a follow-up question in the same thread.
Google’s example was a bookshelf. Lens recognised each book, considered how the books related to each other and suggested similar titles with links. You can use it for any busy scene: a desk, a fridge shelf or a wardrobe.
Method 2: use Ask Gemini on your Android phone
If your phone supports it, you can launch Gemini by pressing the side button (or using the voice trigger) while something is on screen.
- Open the page, photo or app you want help with.
- Launch Gemini with the side button or by saying the wake phrase.
- Choose the option to ask about your screen. Gemini captures what is showing.
- Type or say your question, such as “Summarise this article” or “What does this error mean?”
The capture is saved to your Gemini chat history, so you can come back to it later. If your phone lacks the screen option, take a screenshot, open Gemini and attach the picture. It takes an extra step but works the same way.
Method 3: send a photo to the Gemini app on iPhone or Android
- Open the Gemini app.
- Tap the plus button in the prompt box and choose camera, photos or files.
- Pick or capture the picture.
- Write a clear question. A good pattern is what you want + what to focus on + the format: “Read this receipt and list the items and prices in a table.”
Our list of Gemini prompts includes many that work well with pictures and documents.
Method 4: Gemini in Chrome on desktop
On a computer, you don’t need to leave the page. Chrome has an “Ask Gemini” button, and a newer tool lets you point at what you want.
- Make sure you are signed in to Chrome with your Google account and that Gemini in Chrome is enabled. It does not work in Incognito windows.
- Click “Ask Gemini”.
- Click the plus sign to open the Add menu.
- Choose “Select from screen” and draw boxes around the parts of the page you care about. You can select more than one area.
- Type your prompt, for example “Compare these two prices” or “Explain this graph”.
Reports say the tool is rolling out gradually and needs a recent version of Chrome. If you can’t see it, update the browser first. You can also use Lens in Chrome to search with an image from a web page.
Method 5: create and edit images in Lens
In October 2025, Google added a Create option to Lens and put Nano Banana into AI Mode. After you capture a photo, the image goes into the AI Mode prompt box, where you describe the edit you want. Google said it was rolling out in English in the US and India, with more countries and languages to follow. If you can’t find it where you live, try the full Gemini app instead. Our Nano Banana prompt guide shows how to word an edit.
Good questions to ask about a picture
- “Identify this plant and tell me how often to water it.”
- “Read the text in this image and translate it into English.”
- “What’s wrong in this screenshot? Explain the error in plain words.”
- “Turn this handwritten list into a tidy checklist.”
- “Describe the objects on this shelf and suggest how to organise them.”
- “Compare the two products in this photo and show a table of the differences.”
- “Explain this diagram to a ten-year-old, then give me three quiz questions.”
Why you can’t find the feature
| Problem | Likely reason | What to try |
|---|---|---|
| No AI Mode in Lens | Not rolled out to your account or country yet | Update the Google app, check your language, try again later |
| No Create tab | Available only in some countries and languages | Use the Gemini app for image editing |
| Ask about screen option missing | Device or version difference | Take a screenshot and attach it in Gemini |
| Select from screen missing in Chrome | Old Chrome version or Incognito | Update Chrome, use a normal window |
| Answers look wrong | AI can misread photos | Retake in better light and verify key facts |
Privacy and safety tips
Photos can show more than you realise: addresses, faces, documents and children. Before you send a picture, crop out private details. Don’t upload other people’s photos without a good reason, and don’t share ID or banking documents. Work or school accounts follow their organisation’s rules. Check Google’s privacy settings for how your Gemini activity is stored, and remember that AI answers about plants, medicine or legal papers are general information, not professional advice. Our disclaimer covers this site’s information-only approach.
