Trusted insights
We refine AI outputs with targeted human review to produce reliable, high-quality labels.
Humans: the final frontier
AI that reads your world. See user emotions, intentions, and preferences in video — 20x faster and for a fraction of the cost.
AI that can read the room!
We help AI understand how people feel and respond by combining multimodal models with targeted human insight.
Real-world context
We use large-scale video, audio, and log data to capture how emotional responses vary across real-world situations.
Human-like intent
Systems that better match how people perceive and interpret multimodal content.
Unlocking the final frontier of AI: truly understanding humans.
Today’s AI struggles to understand human emotion, intent, and preferences because it learns mostly from static text. We combine video-based AI with trusted and targeted human feedback to better capture real emotional signals and reduce noise.
We use focused, high-quality human feedback only where it matters most, reducing the need for large-scale labeling. This helps quickly refine vision-language models by improving accuracy with less data and faster iteration.
Time-based feedback
High-bandwidth human signals captured at the speed of thought, frame by frame.
Behavioral science
AI methods paired with deep insights from human psychology to surface what matters.
One platform, many domains
From games to healthcare, the platform adapts to the signals each field needs.
Video Engine
Few-shot and transfer learning meet video understanding, and proprietary AI-human co-annotation models.
Built for Cross-Industry Applications
The HF.ai platform is designed for scenarios where understanding humans matters. It captures signals like attention, fatigue, stress, and engagement, and can be applied in driver assistance systems, warehousing, patient care, social media, games user research and beyond
Alertness
Attention
Empathy
Engagement
Fatigue
Stress
From raw video to actionable insight.
A guided workflow that blends AI speed with human judgment — annotate, refine, and surface the moments that matter, all in one place.
AI labels
Get quick labels from our video understanding agents
Task
Let AI select sections that require further clarification and send them to human annotators.
Annotation
Human annotators provide reliable, time-continuous labels on the videos.
Insights
Get insights that enable informed decision-making for your next move.
Refine & Improve
Iterate on your AI models with targeted feedback loops. Retrain on validated labels to boost AI model accuracy
Built on research, tuned for reliability.
A stack designed to do more with fewer labels — combining few-shot temporal models, annotator evaluation and automated quality control, all rooted in decades of academic research.
Few-shot temporal learning
Generalize labels from a handful of annotations — taking time-continuous data labeling to the next level.
Less but more reliable data
The breakthrough isn't volume, it's quality. Focus annotation effort exactly where it moves the model.
Annotator reliability estimation
Automatically detect unreliable annotators early to keep subjective labels grounded in trustworthy truth.
AI-powered automation
Integrated tools for cleaning, processing and visualizing feedback — built on years of academic research.
Built by leaders in affective AI.
