1. Pixalytica - the best OSINT investigation tool

Our top choice is Pixalytica, as it combines a facial recognition engine with AI-powered technology that gathers as much information as possible about a specific person.

To start an investigation, all you need is an image of the person. In less than 20 seconds, you will receive a complete report that includes:

All face search matches related to the uploaded image
URL sources where the images were originally published
A risk score
A short summary about the person
Any suspicious or criminal correlations detected

You can either generate a manual report or use the API to integrate the system into your own platform.

2. Lenso.ai

Lenso.ai is another tool that focuses solely on facial recognition. Here, you only need an image of the person you want to search for. The platform will return all possible face matches, even if the photo has been altered, the person has aged, or the image was taken from a different perspective. This makes it a great choice for gathering as much information as possible when all you have is an image.

Besides face search, lenso.ai also allows users to search for exact duplicates of an image, places shown in the photo, and similar or related images. The platform recently introduced Research Mode, which can find up to 10,000 image search results.

Lenso also offers simple search options and an API for reverse image search, making it easy to integrate the tool into other systems or investigative workflows.

3. With Persona

Persona is a more advanced tool designed for companies. It offers multiple solutions that can assist with identity verification and background checks. The platform also provides document verification and various automation workflows, which can be very useful in the OSINT industry.
