How to Use Lenso AI: A Complete Tutorial for Reverse Image Search

Finding the original source of an image is not always easy. A photo may be reposted on different websites, edited, cropped, used without credit, or shared under a different name. In many cases, typing keywords into a search engine is not enough because you may not know what to search for.

That is where reverse image search becomes useful. Instead of describing an image with words, you can upload the image itself and search for visually similar results across the web.

Lenso AI is one of the tools built for this purpose. It allows users to search by image across categories such as people, places, duplicates, similar images, and related visuals. It also includes features like face search, source tracking, filters, alerts, collections, Research Mode, and API access for developers.

In this guide, we’ll walk through how to use Lenso AI step by step, what each feature does, and how to get better results from your searches.

What is Lenso AI, and why use it?

Lenso AI is a reverse image search tool built with AI-powered image recognition technology. It allows users to upload, paste, or drag an image into the platform and search for matching or related images across different categories.

This AI is useful when a normal text-based search is not enough. For example, you may have an image but not know where it came from, who appears in it, where it was taken, or whether it has been reused somewhere online.

You can use Lenso AI to:

• Find where your photos appear online.
• Check if someone is using your images without permission.
• Find duplicate, cropped, edited, or filtered versions of an image.
• Search for a person using face search.
• Identify places, buildings, landscapes, or landmarks.
• Find visually similar images for research or inspiration.
• Track image usage over time with alerts.
• Add reverse image search features to an app using the API.

How to Use Lenso AI

In this section, you’ll explore how to use Lenso AI step-by-step:

Step 1: Visit Lenso AI

• Go to Lenso AI using your desktop or mobile browser.
• On the main page, you can start a search by uploading an image, dragging it into the upload area, or pasting it. 
• The platform also supports image-based searching across categories such as people, places, duplicates, similar images, and related images.

Step 2: Upload Your Image

• Choose the image you want to search.
• This can be a portrait, product photo, screenshot, travel photo, artwork, social media image, or any image you want to investigate.
• Once uploaded, Lenso AI scans its image index and displays results based on the content of your image.

Step 3: Review the “All” Results First

• After uploading your image, start with the general results view. 
• It is recommended to check the “All” category first to get a broad idea of what Lenso AI found before moving into a more specific category.
• This helps you quickly understand whether the platform found people, duplicates, similar images, related images, or location-based matches.

Lenso AI Search Categories Explained

Lenso AI organizes image search results into several useful categories. Choosing the right category helps you get more accurate results. Let’s have a look at them: 

1. People: The People category is used for face search. It helps find the same person in different photos, environments, hairstyles, expressions, or accessories. This is useful for checking where your face appears online or finding public images of a person from a photo.
2. Duplicates: The Duplicates category helps find exact or near-exact copies of an uploaded image. It can detect edited, cropped, filtered, or altered versions of the original image. This is one of the best categories for copyright checks, image theft detection, and source tracking.
3. Places: The Places category helps identify similar landscapes, buildings, landmarks, and locations. This can be helpful when you have a travel photo, an architecture image, or an unknown location and want to find visually similar places.
4. Similar: The Similar category shows images that look like your uploaded image but are not necessarily duplicates. These results may share a similar layout, subject, color, style, or visual composition. This is useful for visual research, design inspiration, marketing, and content planning.
5. Related: The Related category shows images connected to your uploaded image, even if they are not visually identical. This can help you discover contextually connected visuals, related topics, or broader image matches.

How to Check Image Sources

To find where an image appears online, open a result and check its source. Users can open the source page, view the image in a new tab, or save the result.

This is especially useful when you want to know:

• Where an image was published
• Who used the image
• Whether your photo was copied
• Which website hosts the image
• Whether an image has multiple sources

How to Use Filters in Lenso AI

Filters help narrow your results and make searches more accurate. Lenso AI supports basic filters such as:

1. Text filter: Add keywords to guide your search
2. Domain filter: Search within a specific website or domain

For example, if you want to check whether your image appears on a certain website, you can use the domain filter. The tutorial recommends using English words for text search and top-level domains for domain filtering.

How to Sort Search Results

Lenso AI also allows users to sort image results. You can sort by:

• Newest or oldest results
• Best or worst match
• Random results
• Diverse results

Use “Best Match” when you want the most accurate results first. Use “Newest” when you want to find recently indexed image matches. Use “Diverse Results” when you want broader variations of the same person, place, or object.

How to Set Alerts in Lenso AI

Alerts are useful when you want to monitor an image over time. To set an alert:

• Upload your image
• Open the category you want to monitor
• Click the alert or bell icon
• Name your alert
• Save it

Lenso AI stores alerts in the user panel and can send email notifications when new matches are found. This feature is helpful for photographers, brands, content creators, public figures, and anyone who wants to monitor image reuse online.

How to Use Research Mode

Research Mode is a deeper search feature available with the Professional subscription.

It gives access to more results and advanced filters. According to Lenso AI, Research Mode can provide up to 10,000 results for People and Duplicates searches. It also includes advanced filters such as language, domain, date range, image size, and keyword in page title.

Research Mode is useful for:

• Copyright investigations
• Face search
• Brand monitoring
• Source verification
• Large-scale image research
• Finding more duplicate results

How to Save Results to Collections

Lenso AI lets users save useful results to Collections. You can save individual results, multiple sources, or all sources connected to a result. Saved results are stored in your user profile so you can revisit them later.

Collections are helpful when you are organizing research, building a copyright case, tracking image usage, or comparing multiple sources.

How to Use Lenso AI API

Lenso AI also offers API access for developers. The API allows developers to add reverse image search and face search features to their own applications. The product page states that the Developer subscription includes API access and up to 5,000 API calls per month.

This can be useful for:

• Software platforms
• KYC tools
• Copyright monitoring tools
• Marketplace verification
• Media monitoring systems
• Image processing workflows

Conclusion

Lenso AI is a useful AI reverse image search tool for anyone who needs to find where an image appears online, detect duplicates, search for faces, identify places, or verify image sources. Its category-based search makes the process simple, while features like filters, sorting, alerts, Collections, Research Mode, and API access make it practical for both casual and professional users.

For photographers and creators, Lenso AI can help protect visual content. For marketers and researchers, it can speed up visual discovery and source verification. For developers, it offers a way to integrate reverse image search into custom apps without building the technology from scratch.
