What else you get

Auto pre-labeling

We make suggestions based on what has already been processed before. You only need to approve or correct the suggestions while labeling your own datasets.

Native Active Learning

Heartex uses cluster annotation and active learning to train your model on diverse examples first. You can fine-tune the model by labeling similar objects later to optimize the model’s quality score.

Transparent process

If your data set has missing variables, or your collaborator labeling results differ too much, you'll see that early enough. Make adjustments and save time and money on labeling everything — just monitor the model's quality score at the early stages of training.

Easy to get started

  1. Sign up for Heartex and add your dataset objects
  2. Connect your AI model through Heartex API or choose one of our pre-trained models
  3. Label a small batch of objects, yourself or collaboratively with your team members
  4. See your model’s quality score improve as you go through the dataset
  5. Start using your model as soon as you want. If necessary, you can keep improving its quality score as you go.
