Multimodal Data

Beyond text — with the same discipline.

Modern models see, hear and read. OmniTech annotates and evaluates across images, video, audio, speech and documents — with domain specialists and the layered quality assurance that governs our text work.

Scope a multimodal program By modality
By modality

Annotation and evaluation across every input.

Images

Classification, bounding boxes, segmentation, captioning, attribute tagging, and generation-quality & prompt-adherence review.

Video

Temporal labeling, event and action tagging, tracking, and evaluation of generated video for coherence and artifacts.

Audio & speech

Transcription, diarization, intent and sentiment labeling, pronunciation review, and TTS/voice quality evaluation.

Documents

Layout and entity extraction, key-value and table parsing, classification, and evaluation of document understanding.

Text

NER, classification, spans, relationships and structured extraction — the foundation, done to spec.

Cross-modal

Image-text and video-text alignment, grounding, and multimodal instruction-following evaluation.

We deliberately scope to modalities we can staff and qualify for. We do not claim specialized capabilities — such as LiDAR, sensor-fusion or clinical medical imaging — unless we can genuinely build the qualified team for your program. Ask, and we’ll be straight with you.

Working with physical-world demonstrations?

Our Physical AI specialization covers egocentric collection, action segmentation and interaction labels with dedicated quality workflows.

Physical AI & Egocentric Data
Specialists, not a generic crowd

The right eyes on the right data.

A radiology-context caption, a legal document, a generated film clip and a multilingual voice note need different expertise. We qualify contributors per modality and per domain — and hold them to gold standards and adjudication just like every other program.

  • Modality- and domain-specific qualification
  • Consistent guidelines and edge-case libraries
  • Layered QA, secondary review and adjudication

Tooling

Tool-agnostic by design

Teams work in your platform, an approved third-party annotation tool, or a client-controlled environment — whatever your security and workflow require.
