Online investigation: understanding the OSINT industry
Investigations moved online a long time ago. First of all, it's much easier and faster to find information about a specific person, and secondly, people leave a lot of digital footprints across the internet.
However, a simple Google search is often not enough, and the whole process can be time-consuming because there is simply too much information appearing online. That's why it's better to use reliable tools that can make the entire investigation process more effective and faster.
The OSINT industry is a result of the shift toward online investigations. More and more specialists rely mostly on online investigation tools to verify information and solve cases.
Today, many investigations are conducted entirely within the OSINT ecosystem, involving dedicated specialists, platforms, and even companies that focus exclusively on open-source intelligence.
AI Face Search in OSINT and Investigations
Best website to investigate someone online in 2026
Lenso.ai is currently one of the best solutions for investigating someone online, as it offers not only an advanced reverse image search engine but also one of the best face search tools available, along with many additional features that can support your investigation.
By having only an image, you can reveal as much information as possible about a specific person and discover clues that may be crucial to an ongoing investigation. Let's check how exactly lenso.ai can help you.
How to investigate someone online with lenso.ai ?
As mentioned earlier, all you need to start with is an image.
The best approach is to collect various photos of the person you want to investigate (taken from different angles and at different ages), as this may bring different results. The better the image quality, the better the results are likely to be.
Search by face
Once you upload an image to lenso.ai, you'll see several categories of results. Let's start by checking the "People" category, as this is where you'll find exact face matches to the photo you uploaded, as well as photos:
- featuring the person alongside other people (if any exist)
- taken at different ages
- etc.
Under each photo, you'll find one or more source URLs, making it easy to check where the image was originally published and in what context. Sometimes, these sources can reveal additional information about the person, their background, or even details such as their name and surname.
Find exact copies with copyright image search
If you want to find exact copies of the image you uploaded, simply switch to the "Duplicates" category and check whether there are any matches. As mentioned before, each image result includes one or more source URLs, allowing you to quickly verify where the image was originally published.
Check a general reverse image search
Besides that, you can also search for similar or related images, which may sometimes reveal new information. There is also a text search feature available that can help you find images based on a specific text query.
Try Research Mode
And that's not all! Lenso.ai offers many more features, one of which is Research Mode. This feature enables a deeper search and can reveal up to 10,000 image search results within the "People" and "Duplicates" categories.
Besides that, there are advanced filters available that can make your search even more effective:
- domain filters (include/exclude specific domains)
- keywords in title
- date range
- image quality
- language (include/exclude)
Create Alert for new images
Sometimes, you may not be satisfied with the results or may not find anything at all, but that's not a problem with lenso.ai. You can create an alert for a specific image and category, and whenever a new image match appears, you'll receive an email notification.
This is especially useful for ongoing online investigations, particularly when there is very little information available about a specific person and you're looking to uncover any new leads.
Implement API into your own investigation service
If you're operating at a more advanced level or running your own investigation platform or company, you may be interested in implementing a face search API and lenso.ai offers that option as well.
You can easily integrate lenso.ai's facial search engine into your own system. The API also comes with several advanced filters, making it an even more powerful solution:
- domain include/exclude
- date range
- best match / worst match sorting
Alternative websites for online investigations
Besides lenso.ai, there are plenty of reliable investigation tools that may help you. Here are some of the platforms worth trying:
- pixalytica.com: for KYC verification and background check reports.
- eyematch.ai: focused exclusively on face search.
- skopenow.com: provides comprehensive online investigation solutions.
- penlink.com: offers digital intelligence and investigative tools.
- fivecast.com: specializes in fraud detection and intelligence gathering.
