The right image annotation tool for the right use-case

Choose the annotation tool according to your project, your model, your objectives and your budget.
Build your annotation project pipeline with the help of our project manager and customize the components according to your needs: APIs, KPIs, UX, QC, Labels, etc.
Our solution: an image annotation platform + a dedicated project manager + a trained workforce  


This type of annotation is the simplest and the most cost-effective but it often generates a lot of noise, making therefore the learning more difficult. With our oriented 2D Bounding Box solution, we can reduce the noise by up to 80%.

  • Classic or oriented 2D Bounding Box

  • Hierarchization of labels

  • Output format customization

  • UI customization

  • Annotation outside the image


Get additional data to the 2D annotation such as width, height and depth to train your algorithm.

  • Automatic 3D Bounding box

  • Label hierarchy

  • Visualization of a treasury

  • Output format customization

  • UI customization

  • Annotation outside the image


Annotate your objects by delimiting their contours to remove any possible noise and thus facilitate the learning of your model. Our Polygon annotation tool offers a wide range of features to meet all your needs:

  • Annotation by instance

  • Infinite number of segments

  • Point orderings

  • Output format customization


Easily generate pixel-perfect masks from your annotated images to train your computer vision model. Segmentation is a precision job; that's why we focused on the fluidity and technicality of our tool.

  • Zoom up to x42

  • Automatic removal of unlinked segmentations

  • Management of occlusions and overlays

  • Automatic edge detection

  • Color customization

woman's face annotated by the "order of points" technology - computer vision


Train your facial recognition models to detect emotions and expressions with ease with our customizable point annotation tool.This annotation technique requires a methodical and chronological work where rigor is essential; that's why we have developed a specific interface.

  • Odonnation of points

  • Annotation of extreme points

  • Annotation outside the image

  • Customization of the UI

  • Customization of the output format


Train your human, animal or any other ordered structure skeleton recognition models with our customizable point annotation tool.
This annotation technique requires methodical and chronological work where rigor is paramount which is why we have developed a specific interface:

  • Forced scheduling to limit errors

  • Annotation of the extreme points

  • Annotation outside the image

  • Customization of the UI

  • Customization of the output format


Train your computer vision model to recognize and delineate lanes, streets, sidewalks, parking spaces ... thanks to our Polyline annotation tool developed specifically for autonomous vehicles.
The Polyline is a technical annotation because the variables are numerous. This is why isahit has developed an intuitive interface to easily manage a large number of annotations:

  • Polyline by Instance

  • Overlay of annotations

  • Hierarchy of labels

  • Visualization of a thesaurus

  • Customization of the output format

  • UI customization


Improve the performance of your model with our 'Human in Loop' transcription solution. We correct in real time the predictions of your algorithms and thanks to our diverse community of contributors (+39 countries and 20 languages) and intervene on international issues.

  • Customized API

  • Diverse workforce trained in these subjects

  • Response time under 30 seconds

  • Customization of the transcription tool

  • Transcription system using Dialogue and Timestamp


Get the most out of your classification project, which usually seems so easy but can quickly become complex as the list of classes grows.
Our classification tool makes complex projects manageable because we reduce subjectivity with an intuitive classification interface.

  • Dynamic label list

  • Classification system with scale

  • Hierarchization of labels

  • Visualization of a thesaurus

  • Customization of the UI


Lidar 3D point Cloud Annotation is one of the most difficult annotation and required a robust & fast annotation tool but also a workforce trained specifically to your use-case and supervised by a dedicated and experienced project manager. We developed our solution based on our client's feedback to match all their needs.

  • Dynamic label list

  • Smooth navigation

  • Customised label display

  • Visualization of a thesaurus
