The Future of Data Annotation

Your voice is the
fastest annotation tool
ever built.

We didn't build Voice Annotation because it was easy.
We built it because 1.3 billion people deserve to annotate data
without touching a keyboard.

The Problem

AI teams were
drowning in
annotation work.

Every AI model needs labeled data. Hundreds of thousands of images, videos, and audio files — each requiring a human to carefully describe what they see, click bounding boxes, type labels, and submit.

The process is slow. It is expensive. And it excludes the vast majority of the world's population who either don't have the technical training or the physical ability to work with annotation tools built for keyboards and mice.

We watched medical researchers in developing countries struggle to annotate X-rays. We saw automotive engineers manually label thousands of frames. We met ML teams paying $2,000 per month for annotation platforms that still required hours of manual work.

Before vs After

Traditional Annotation

Open annotation tool, find the image, zoom in, draw bounding box
Manually type each label — color, position, condition, size
Export to specific format, convert manually for each team
Average 45-90 seconds per annotation
Requires technical training and desktop access

AnnotateAI Voice

Open browser, press the microphone button
Speak naturally — "red sedan, left door damage, moving forward"
Instant export to JSON, YOLO, COCO, CSV, HuggingFace and more
Average 8-12 seconds per annotation
Works on any device, in 50+ languages, no training required
"We didn't want to build another annotation tool. We wanted to remove annotation as a bottleneck entirely.

Industries We Serve

Built for the teams
building tomorrow's AI.

Medical AI

Radiology & Diagnostics

Radiologists describe findings out loud as they review scans. Voice Annotation captures anatomy, severity, size, and recommendations — structured instantly for ML pipelines.

70% faster than manual labeling

Autonomous Vehicles

LIDAR & Camera Labeling

Engineers label traffic scenes, pedestrians, and road conditions at full speed. YOLO and COCO export ready for model training pipelines.

10x throughput vs competitors

E-commerce

Product Recognition

Catalog teams annotate thousands of product images daily. Brand, color, condition, and stock status — spoken once, structured forever.

500+ annotations per hour

Defence & Intelligence

Satellite & Aerial Imagery

Analysts annotate aerial imagery hands-free. Coordinates, vehicle types, movement direction — all captured in structured JSON with full audit trail.

Classified-grade data handling

AI / ML Startups

Training Data at Scale

Build high-quality training datasets 6x faster than your competitors. Export directly to HuggingFace, LabelStudio, or your own pipeline.

HuggingFace-ready output

Accessibility

Inclusive Annotation

1.3 billion people with mobility or dexterity challenges can now contribute to AI development. Voice is the most natural human interface ever created.
